Energy-efficient heating for offices, shops and retail

Air Conditioning as an Energy-Efficient Heating Strategy: A Practical Advantage for UK Businesses and Property Owners:

As UK organisations navigate rising operational costs, decarbonisation pressures and tighter emissions expectations, many are reassessing their heating strategy. One technology is emerging as a clear leader for both cost efficiency and sustainability: modern air conditioning systems operating as high-efficiency heat pumps .

These systems are no longer simply cooling appliances; they are versatile, low-carbon HVAC assets delivering highly efficient heating across commercial premises and multi-occupancy buildings — often outperforming traditional gas, oil and biomass systems on both cost and performance.

Exceptional Heating Efficiency With Immediate Operational Benefits

Heat pump–driven air conditioning doesn’t generate heat through combustion. Instead, it transfers heat from the outside air — even in cold conditions — and multiplies the usable output. This gives it a significant efficiency advantage.

Typical performance figures show:

300–400% heating efficiency (COP 3–4)
Substantial reductions in energy consumption compared with gas or oil boilers
Lower carbon intensity, supporting CSR and ESG commitments
Consistent heat delivery with precise digital controls

When energy costs are unpredictable, the ability to generate multiple units of heat from a single unit of electricity provides meaningful and immediate savings for commercial budgets.

The volatility of UK gas and oil prices continues to place pressure on businesses. Air-conditioning-based heating systems, by contrast, offer:

Predictable operational costs
Lower peak demand costs when paired with smart controls or timers
No oil deliveries, no fuel storage, and no exposure to supply-chain price spikes
Reduced maintenance compared with combustion boilers or biomass systems

For many SMEs and commercial property operators, switching key areas — offices, customer-facing spaces, workshops, meeting rooms — to heat-pump-based AC can reduce winter heating expenditure without compromising comfort.

Practical Advantages for Commercial Premises

Air conditioning as a year-round HVAC solution offers several professional advantages:

Zoned heating control to eliminate unnecessary energy usage
Rapid response times , ideal for variable occupancy patterns
Integrated cooling capability for summer trading and staff comfort
Enhanced indoor air quality via onboard filtration systems
Minimal disruption during installation , especially in retrofit scenarios

For landlords, developers and facilities managers, these systems also streamline compliance with evolving UK environmental standards and offer strong long-term asset value.

A Future-Ready Heating Solution Aligned With UK Policy

As the UK transitions away from fossil-fuel heating, businesses and property investors increasingly need solutions that demonstrate sustainability, resilience, and cost efficiency.

Modern air conditioning heat pumps meet all three requirements:

Contribute to lower carbon emissions
Reduce reliance on oil, gas and solid fuels
Support EPC improvements and future regulatory compliance

Keep outdoor units clear of leaves and frost.

�� The Business Case

A well-maintained system isn’t just about comfort—it’s about protecting your bottom line. Lower energy bills, fewer emergency callouts, and a healthier workplace environment all add up to stronger business performance and higher customer spend.

Final thought: Winter is not the time to forget your air conditioning—it’s the time to future-proof it. Bedfordshire businesses that invest in maintenance now will enjoy smoother operations and fewer headaches when summer rolls back around.

The cost of ignoring maintenance!

Tue, 13 May 2025 21:36:08 GMT

How regular servicing can save your company thousands!

For businesses in Bedfordshire, like many places in the UK, an air conditioning system is not just an expense—it’s an investment.

But what happens when that investment is neglected? Ignoring regular maintenance might seem like an easy way to cut costs, but in reality, it can lead to far bigger expenses down the line.

1. Higher Energy Bills: Over time, dirt, dust, and wear can cause your air conditioning system to work harder to achieve the same results. This inefficiency drives up energy consumption and, in turn, your utility bills. Some studies suggest increased energy costs of between 15% and 25%. Regular servicing ensures your system runs at peak performance, keeping costs in check.

2. Costly Repairs or Replacements: Minor issues in your AC system can escalate quickly if left unchecked, leading to major breakdowns that require expensive repairs—or even a complete replacement. Routine maintenance helps identify and fix these problems early, saving your business thousands in emergency costs.

3. Lost Productivity: A malfunctioning air conditioning system can disrupt your business operations. Whether it’s overheating equipment or uncomfortable employees, the downtime and reduced productivity can significantly impact your bottom line. Most people associate air conditioning systems as purely providers of comfort to individuals, but think of the applications like server rooms, ICT suites, labs and product storage facilities. Preventative servicing helps you avoid these unnecessary interruptions.

4. Shortened Lifespan: Neglecting maintenance can cause undue strain on your system, leading to faster wear and tear. Regular servicing can extend the lifespan of your AC unit, maximizing your investment and deferring the need for a costly replacement. If a typica system replacement cost is in the region of £2,000.00, wouldn't you prefer to service your system regularly, in lieu?

5. Potential Legal and Compliance Issues: Depending on your industry, maintaining optimal indoor air quality could be a legal or regulatory requirement. Regular air conditioning servicing helps ensure you stay compliant and avoid any penalties or reputational damage.

6. Manufacturers Warranty: with some manufacturers offering significant warranty periods of multiple years, regular servicing should be thought of as an insurance policy. Failure to service your equipment will invalidate your warranty, which means your replacement parts will now need to be paid for, which is potentially thousands of pounds of unnecessary costs!

By committing to routine maintenance, Bedfordshire businesses can not only avoid these risks but also enjoy the peace of mind that comes with knowing their air conditioning system is reliable. Think of it as an insurance policy for your comfort, productivity, and financial health—one that pays dividends in the long run.

Radon - the importance of adequate ventilation!

0017206600 (K EDWARDS) — Fri, 31 Jan 2025 16:41:43 GMT

What is Radon?

Radon is an invisible, odourless and tasteless gas that occurs naturally in soil, rocks and water. As a naturally occurring radioactive gas, it forms during the decay of uranium, which is present in small amounts in nearly all soils. Radon can rise from the ground and enter enclosed spaces like homes, workplaces and schools. Once inside, it can accumulate and pose potential health risks. Some Radon may be present in homes and offices through the presence of items like granite counters or worktops, in small quantities.

Why is Radon testing important?

The Environmental Protection Agency classifies Radon as a carcinogen, and it is the leading cause of lung cancer among non-smokers in the UK. As a result, Radon testing is crucial to ensure the safety and well-being of those living or working in buildings. After, unless you measure something, how can you control it?

How often should a Radon test be carried out?

The frequency of Radon testing is dependent on several factors, including the type of building, the region where the building is located and the presence of other environmental or health-related risks. For commercial buildings, such as office buildings, it is recommended that Radon testing be done at least once a year. Commercial buildings are often in more densely populated areas and are likely to have higher concentrations of Radon due to being surrounded by other buildings with elevated levels of Radon. Additionally, office spaces may have poor air circulation which can further elevate Radon levels. In some areas, with higher than normal background Radon, it is not unknown for mortgage lenders to insist on a Radon test prior to offering a mortgage!

What can be done to combat high radon levels?

Radon can't be removed or reduced, but it can be diluted to safe and manageable levels. That's where we come in - we can install ventilations systems which adequately dilute your environment, be that a home or commercial environment. Get in touch to find out more.

If you would like a Radon test for your office, or home, get in touch today.

What is the 'ideal temperature' of Air Conditioning systems?

Fri, 24 Jan 2025 18:14:46 GMT

The general answer is - whatever suits the individual! But, there are other more specific factors which can assist you if you're wondering about the 'perfect temperature' for your a/c system.

The ideal indoor temperature can vary depending on several factors, including the season, humidity levels, and the age and sex of the occupants(1). Here's a detailed overview:

Winter

During winter, maintaining a balance between comfort and energy efficiency is crucial:

Healthy Adults: The World Health Organization (WHO) recommends setting indoor temperatures to around 18°C for healthy, well-dressed individuals (2).

Elderly and Children: For older adults, young children, or those with health conditions, the ideal temperature is slightly warmer, around 20°C. (3)

Summer

In summer, the goal is to keep indoor spaces cool without excessive energy consumption:

General Recommendation: Aim to keep indoor temperatures between 20-22°C (4). If using air conditioning, you may wish to consider setting your setpoint to around 23-24°C to save energy while maintaining comfort. As a rule of thumb; the higher the ambient temperature, the higher your setpoint can be to still feel comfortable.

Humidity's Role

Humidity levels significantly impact perceived temperature and comfort (5).

High Humidity: Feels warmer, so maintaining an indoor relative humidity (RH) between 30-50% can help manage comfort efficiently (5).

Low Humidity: Can feel cooler but may cause dryness; using humidifiers in winter when heating is on can balance this. Water features, fish tanks/bowls and pot-plants located in the appropriate room can assist with this as well.

Gender and Age Considerations:

Men and Women: Studies indicate that women generally prefer slightly higher indoor temperatures than men. The average neutral temperature can be about 2-3°C higher for women.

Infants: Ideal room temperatures for infants range between 16-20°C to reduce risks associated with being too warm or cold (3).

Older Adults: Keeping main living areas around 20°C ensures comfort and reduces health risks linked to colder environments (3).

Tips to Maintain Ideal Temperature:

Insulation: Proper insulation helps maintain temperature consistency and reduce energy costs (4).

Ventilation: Ensuring good ventilation, especially in high humidity areas like kitchens and bathrooms, helps maintain comfort (5).

Smart Thermostats: Use smart thermostats to automatically adjust temperatures based on occupancy and time of day.

By balancing temperature and humidity, you can create a comfortable and healthy indoor environment for everyone.

Tue, 12 Nov 2024 12:09:10 GMT

We get asked a lot about the efficiency of modern A/C units and, in truth, its a complex query with many answers.

In an era where energy efficiency is paramount, modern air conditioning units have made impressive strides. These advancements are not just about cooling our homes and offices, but doing so sustainably and economically.

1. Energy Efficiency Ratings: Today's AC units come with improved SEER (Seasonal Energy Efficiency Ratio) ratings. Higher SEER ratings mean more efficient units, leading to lower energy consumption and reduced utility bills.

2. Smart Thermostats: Integration with smart home technology has revolutionized how we control our indoor climate. Smart thermostats learn your habits and adjust the temperature accordingly, ensuring optimal comfort while saving energy.

3. Inverter Technology: Unlike traditional units that operate at full capacity until the desired temperature is reached, inverter ACs adjust their speed to maintain a constant temperature. This reduces wear and tear on the unit and significantly cuts down on energy use.

4. Eco-Friendly Refrigerants: Modern units use refrigerants that are less harmful to the environment. These eco-friendly options not only reduce greenhouse gas emissions but also improve overall system efficiency.

5. Regular Maintenance and Upgrades: Regular servicing of AC units, including cleaning filters and checking for leaks, ensures they operate at peak efficiency. Upgrading older systems to newer, more efficient models can also provide significant savings.

In conclusion, the efficiency of modern air conditioning units is a blend of advanced technology, smart controls, and eco-conscious materials. These innovations not only enhance our comfort but also contribute to a more sustainable future.

Legionella and Air Conditioning

0017206600 (K EDWARDS) — Wed, 07 Aug 2024 18:16:05 GMT

and do you need to be worried?

Firstly, where does Legionella come from?

Legionella is a bacteria found in most natural bodies of water throughout the world, and in man-made water systems such as hot tubs, cooling towers, fountains, some air conditioning systems, and showers. It is not found in chlorinated water systems or well water. The bacteria can be spread through airborne droplets, and people become infected when they breathe in contaminated mist or vapour.

Old plumbing systems can provide a hospitable environment for legionella to proliferate as well. If these systems are not properly maintained and cleaned, the chances of contracting Legionnaires’ disease increase significantly. It is important to keep these systems clean, sanitized, and well-maintained to reduce the risk of infection.

Thats all very well, you might say, but what are the risks of contracting Legionnaires disease from my air conditioning system?

The reality is, the risk is very small. The fact is, from an air conditioning system point of view, there are not that many a/c systems in the UK which are capable of allowing Legionella to proliferate. Your split system or VRF system, installed in your home, or office or shop is not at risk of giving you Legionnaires disease. This is because Legionella is a water-borne bacteria and does not thrive in the types of a/c systems which are used in the UK. In the UK we primarily use split systems, multi-split systems, VRF & VRV systems. These kinds of systems do not use water as a cooling agent, and, whilst its true these systems do generate condensate as a waste product, the water is not present in the conditions needed to allow legionella to proliferate.

What are those conditions? Good question! These are mainly:

the water temperature in all, or some, parts of the system should be between 20-45 °C, which allows growth of the bacteria
it is possible for water droplets to become aerated and then airborne , as in an aerosol form.
the water will be well shaded and out of direct sunlight
there are deposits within the water that can support bacterial growth via nutrients for the organism growth e.g. rust, sludge, scale, organic matter and biofilms

Typically, these are not conditions found in the average UK a/c system - with the exception of Cooling Towers.

Oh, well what are Cooling Towers?

These are the often quite large systems, usually located on the rooftop of commercial buildings, which dissipate the heat from the water coolant which is used to cool down the hot components of large commercial a/c systems. This kind of system is not that common in the UK nowadays and is only ever seen on large commercial sites. We believe Legionnaires disease, whilst serious and of concern in larger commercial systems, is not an issue which the average user or owner of an a/c system in the UK will need to be worried about.

What are the dangers of Legionella?

Legionella bacteria can cause a potentially fatal form of pneumonia called Legionnaires' Disease, as well as the less severe Pontiac Fever. People exposed to Legionella bacteria can become very ill and even die from this infection. The symptoms of Legionnaires’ Disease include fever, coughing, chest pains, and difficulty breathing. Anyone can become infected with Legionella bacteria, but those at higher risk include people over the age of 50, smokers, those with chronic lung disease, people with weakened immune systems, and those who take medications that suppress their immune system.

What are multi-split systems?

0017206600 (K EDWARDS) — Sat, 01 Jun 2024 13:18:02 GMT

We are often asked; "Can more than one indoor unit be connected to just the one outdoor unit?"

In a word - YES! This type of system is called a multi-split system and differs slightly from a split system, which is a system which has one outdoor unit connected to one indoor unit.

A multi-split system is a design of a/c system that shares similarities with a split system but allows for multiple indoor units to be connected to a single outdoor unit.

In a multi-split system, each indoor unit serves a separate zone or room within the building, providing individualized climate control. These indoor units can vary in type and capacity, such as wall-mounted units, ceiling cassettes, or ducted units, depending on the specific requirements of each space.

The outdoor unit of a multi-split system contains the compressor, condenser coil, and fan, which is similar to a traditional split system. However, it is designed to accommodate multiple refrigerant lines connected to the various indoor units and this is the primary difference between the to systems

Multi-split systems offer several advantages:

Flexibility: With the ability to connect multiple indoor units to a single outdoor unit, multi-split systems offer greater flexibility in terms of zoning and installation options. This makes them suitable for buildings with multiple rooms or areas that have different cooling or heating needs.
Space-saving: By consolidating the outdoor equipment, multi-split systems help save space and reduce the 'footprint' and visual impact of HVAC installations, especially in situations where installing individual split systems for each room may not be feasible.
Energy efficiency: Multi-split systems often incorporate advanced technologies, such as variable-speed compressors and individualized temperature control, to optimize energy consumption and reduce operating costs.
Cost-effectiveness: While multi-split systems may require a higher initial investment compared to single-split systems, they can offer cost savings in the long run, particularly for buildings with multiple zones or rooms that need to be cooled or heated.
Customization: Multi-split systems allow for customization based on the specific requirements of each space, including the selection of indoor units with different capacities, styles, and features to meet the occupants' comfort preferences.

Overall, multi-split systems provide efficient and customizable cooling and heating solutions for buildings with multiple rooms or zones, offering comfort, space savings, flexibility, and energy savings.

What is a 'split system'?

0017206600 (K EDWARDS) — Thu, 11 Apr 2024 11:00:20 GMT

We are often asked 'what exactly is a split system?'

We know the Air Conditioning industry is guilty of using a lot of confusing jargon, but this one is very easily explained!

A Split System is a type of Air Conditioning setup that consists of two main components: an indoor unit and an outdoor unit. The way to remember it is - you have an indoor and outdoor unit and they are 'split apart' and connected by pipework.

The indoor unit typically contains the evaporator coil, air filter, and blower fan (sometimes called a scroll or fan wheel), which are responsible for cooling or heating the air inside the building. This unit is usually installed in a room or space that requires climate control, such as a living room, bedroom, or office.

The outdoor unit, more accurately known as the condensing unit, houses the compressor, condenser coil, and fan. Its primary function is to release heat absorbed from the indoor air into the outdoor environment, allowing the refrigerant to cool and circulate back into the indoor unit to continue the cooling or heating process.

A split system operates by circulating refrigerant between the indoor and outdoor units through a set of refrigerant lines, or pipes. These systems are known for their simplicity, efficiency, and versatility, making them popular choices for residential and small commercial applications.

Split systems offer several benefits, including:

Space-saving: The separation of the indoor and outdoor units allows for flexible installation options, even in spaces with limited room for bulky HVAC equipment.
Quiet operation: With the noisy components such as the compressor and condenser fan located outdoors, split systems tend to operate more quietly compared to traditional HVAC systems. Modern indoor units are often circa 19dba on low speed!
Energy efficiency: Split systems often incorporate advanced technologies, such as inverter compressors and variable-speed motors, to optimize energy consumption and reduce utility bills.
Zoning capabilities: Some split systems support zoning, which enables different areas of a building to be controlled independently, enhancing comfort and energy efficiency. These split systems are called 'multi-splits'.

Overall, split system air conditioning systems offer effective cooling and heating solutions while providing comfort, efficiency, and flexibility for a variety of residential and commercial applications.

Spring Servicing

Sun, 25 Feb 2024 16:03:54 GMT

and why is it important?

Well, it seems Spring is just around the corner. It's likely you've seen the daffodils and other bulbs starting to flower, you'll have seen the colourful blossoms starting to appear on the trees and, no doubt, you've noticed the days are starting - ever so slowly - to get longer. It all means summer is just around the corner!

It also means that your a/c is likely to need its Spring service as well. There's a good chance your condensing unit - the outdoor unit, in other words - has a fair amount of leaf debris and perhaps even vines or moss build-up around it and this can seriously impact its performance.

There's also a good chance that you'll have some bacteria build-up on the evaporator coil of your indoor unit and this can cause some unpleasant smells. Many people comment that this smell is like an ammonia or a urine-like odour and, whilst it's not dangerous, it can be quite unpleasant. It's most noticeable as you change from cooling to heating, or vice versa, and with the cooling season around the corner, there will be many of you who might be affected by this. The good news is that this is very easily treated; we apply a biocide to evaporator coils as part of our servicing and then apply a deodouriser application afterwards which leaves the unit nice and fresh smelling.

Of course, a service will include more checks on your system to ensure its running smoothly and is ready to face the coming warmer months. Get in touch today and we'll ensure your unit is fighting fit and ready for whatever the summer months throw at us!

Why does your a/c unit smell?

Mon, 09 Oct 2023 22:25:54 GMT

At Bedfordshire Air Conditioning we are often asked about smells from Air Conditioning systems. It’s not a pleasant subject and it’s quite subjective too as, what one person finds unpleasant another person may not, and what someone can smell quite strongly, someone else might not be able to smell at all.

However, usually a smelly air conditioning unit can be attributed to several factors:

1. Mould or Mildew: the evaporator coils and other parts of the indoor unit can accumulate moisture or condensate over time, creating a damp environment that’s conducive to the growth of bacteria, mould and mildew. These micro-organisms can produce unpleasant odours.

2. Clogged Drain Pipe, or pump: a clogged drain line lead to water build-up in the unit, creating a breeding ground for bacteria, mould and mildew. The stagnant water can emit musty smells.

3. Dusty Filters: if the air filters are dirty, they can become a source of odours as dust, dirt and debris accumulate on them.

4. Stagnant Water: water that doesn’t properly drain or evaporate can become stagnant and emit bad smells.

5. Chemical Odours; sometimes, a chemical or burning smell can indicate a problem with the units electrical components, or wiring. Be aware of this one and call us out straight away if you experience this!

6. Outside contaminants: if outdoor air pollutants enter the unit, they can contribute to bad smells circulating through the system.

7. Inside contaminants: remember your air conditioning unit will, in the main, only recirculate air already in your room. If you have food which has gone off in the office somewhere, or a water-logged pot plant where the soil has become stagnant/sour or perhaps if your return air grille is positioned too close to a kitchen or the toilets (yes; we have had all of these situations in the past!) then your a/c unit may simply be circulating odours which already exist within the room.

To address these issues, consider the following steps:

* Regularly clean or replace air filters

* Keep the unit maintained and clean, including the evaporator coils and drainage system. Your unit may need a biocide application - ask us what this means!

* Use a professional HVAC company – like Bedfordshire Air Conditioning – for regular maintenance and inspections.

* Run the fan on the unit for a while after turning off the cooling, to help dry out any excess moisture - this is easy and can be done by anyone. In fact, a lot of modern a/c units have this function automatically.

If the sell persists or seems unusual, it’s a good idea to consult with us to diagnose and address the specific cause of the odour. Why put up with a smelly a/c unit?

What are the benefits of installing Air Conditioning?

0017206600 (K EDWARDS) — Wed, 30 Aug 2023 17:18:29 GMT

We were recently asked by a customer - "why should I have a/c installed? I mean, what reasons are there?"

Good question! While the answers might seem obvious to us, perhaps there are other customers who are thinking the same. So, perhaps a good premise for this months blog!

Ok, well there are several reasons why someone might want to install air conditioning. Here are some potential benefits of air conditioning:

Comfort: Air Conditioning can help to maintain a comfortable indoor temperature during hot weather, making it easier to sleep, work, and relax. Of course, the same is true in winter as all Air Conditioning systems can heat as well.
Improved air quality: Air conditioning can help to filter and cleanse the air, removing pollutants and allergens that can cause respiratory problems and other health issues. Some Air Conditioning systems have quite fine filters which allow them to remove very fine particles and some manufacturers, like Panasonic and LG, offer systems which can ionise water particles in the air, which can inhibit mould, pollen, viruses, bacteria and even odours!
Increased productivity: When temperatures rise, people tend to feel sluggish and less productive. Air conditioning can help to improve focus and concentration, which can lead to increased productivity and better work performance.
Better sleep: Sleeping in a hot and humid environment can be difficult and uncomfortable. Air conditioning can help to create a cool and comfortable sleeping environment, leading to better sleep quality and more restful nights.
Energy Efficiency: All Air Conditioning systems can heat as well as cool these days and all Air Conditioning systems are Heat Pumps too, which means they are very energy efficient whilst in heating mode. Why not use your a/c system to heat your office, bedroom or living room instead of your central heating system - and save some money whilst doing it?
Protection of equipment: Air conditioning can help to regulate the temperature and humidity in a room, which can help to protect sensitive equipment, like computers and servers, and prevent damage from heat and moisture.

Overall, installing air conditioning can help to improve comfort, air quality, productivity, sleep quality, and the protection of equipment. It can be particularly beneficial during the hot summer months when temperatures can be high and humidity levels can rise but is also very useful in winter when you need energy efficient heating!

Does my A/C unit need a 'top up' of gas?

0017206600 (K EDWARDS) — Mon, 14 Aug 2023 19:18:41 GMT

Air conditioning units use a refrigerant to cool the air. This refrigerant, or gas, circulates around the system in a sealed and infinite cycle; it doesn't get 'used up' or get burned etc. If a system is operating as it should, that gas will circulate throughout the pipework for as long as the system continues to operate.

So, under normal circumstances, you shouldn't need to add refrigerant to your AC unit regularly, or indeed, at all.

Over time, however, it's possible for the refrigerant levels to decrease due to leaks. If your AC unit is losing refrigerant, it's important to address the underlying issue – typically a leak – rather than just adding more refrigerant. Adding refrigerant without fixing the leak will result in an ongoing problem and can damage the environment due to the harmful nature of some refrigerants. It's also against the law - the F Gas Regulations specifically - for an engineer to add refrigerant to a system without first identifying and repairing the leak(s).

Refrigerants can harm the Ozone Layer and they are significant contributors to Global Warming. Refrigerant is also expensive, so no-one wants refrigerant leaks!

If you suspect your AC unit is losing refrigerant, it's best to contact us as soon as possible. We can diagnose the issue, repair any leaks, and ensure your AC system is working efficiently and safely. In fact, regular maintenance by a professional can help prevent refrigerant leaks and other issues in the first place.

What is REFCOM?

Sat, 29 Jul 2023 14:38:35 GMT

And why should it concern me?

REFCOM is a UK-based organization that is responsible for regulating the refrigeration, air conditioning, and heat pump sector. It is the largest organisation in the UK which is accredited by the UK government to certify businesses that install, maintain, and repair refrigeration, air conditioning, and heat pump systems.

REFCOM was established to ensure that these systems are installed, maintained, and repaired safely and efficiently. It provides a number of services, including certification, training, and technical support, to help businesses in the sector meet the necessary standards and regulations.

REFCOM certification is important for businesses in the refrigeration, air conditioning, and heat pump sector in the UK because it demonstrates that they are competent and reliable. It also helps to ensure that these systems are installed and maintained safely, protecting both the technicians and the general public. If you are a consumer, end user or a customer of a company who installs or services Air Conditioning systems, then you really must ensure that that company is REFCOM registered!

In addition to its certification and training services, REFCOM also promotes best practice in the sector and works with industry partners to develop technical standards and guidance.

Overall, REFCOM is an important organisation in the UK that helps to regulate the refrigeration, air conditioning, and heat pump sector, ensuring that these systems are installed, maintained, and repaired safely and efficiently.

What does Indoor Air Quality mean?

Fri, 07 Jul 2023 21:20:49 GMT

And why is it important?

Indoor Air Quality - or IAQ - refers to the condition of the air inside buildings or enclosed spaces, such as homes, offices, schools, and public buildings.

Good Indoor Air Quality means that the air is clean and free of harmful pollutants and irritants, such as mold, dust, chemicals, and other particles that can cause health problems.

Indoor Air Quality can be affected by a variety of factors, including outdoor pollution, building materials, heating and cooling systems, cleaning products, and even human activities like smoking and cooking. Poor indoor air quality can cause a range of health problems, including respiratory issues, allergies, and headaches.

Maintaining good Indoor Air Quality is important for both the health, productivity and comfort of the people who live or work in a building. Strategies for improving Indoor Air Quality may include proper ventilation, regular cleaning and maintenance of HVAC systems, and the use of air purifiers or other air-cleaning devices.

Simply opening up a window is probably not enough these days to achieve better Indoor Air Quality; for instance the outside air coming in through the window is not filtered and if coming from a busy road or an industrial area, for example, it may not be any better than the internal air anyway. Also, open windows are very energy inefficient, with all the expensive heat being lost to the exterior. Instead, introducing filtered Fresh Air via a MVHR (Mechanical Ventilation Heat Recovery) is a far better option.

R410a refrigerant phaseout

0017206600 (K EDWARDS) — Sun, 28 May 2023 17:18:19 GMT

And what does this mean for you?

R410A refrigerant is being phased out in the UK as part of the European Union's F-Gas regulation, which aims to reduce the use of fluorinated greenhouse gases (F-gases) that contribute to global warming. R410A has a high global warming potential and is being phased out in favor of refrigerants with a lower global warming potential. Refrigerant is the fluid which is circulated around the your a/c system; it is sometimes called 'gas' or 'freon. The former is a generic industry name, the latter is a trade name from a specific manufacturer.

The phase-out of R410A began in 2015, and the EU has set targets to gradually reduce the amount of F-gases that can be sold and used in the EU, including the UK. Specifically, the EU has set a target to reduce the supply of HFCs (hydrofluorocarbons) by 79% by 2030 compared to average levels in 2009-2012.

In the UK, a ban on the use of virgin R410A refrigerant for servicing and maintaining air conditioning and refrigeration systems came into effect on January 1st, 2020. This means that only reclaimed or recycled R410A refrigerant can be used for servicing and maintaining existing systems. From January 1st, 2025, a ban on the use of all HFC refrigerants, including R410A, will come into effect for new equipment and systems with a few exceptions.

Therefore, it is important for individuals and businesses to start planning for the transition away from R410A to alternative refrigerants or more efficient air conditioning systems to comply with the regulations and reduce their environmental impact.

If you own or operate systems using R410a, then you really should be making plans for their replacement in the next financial year or two. Please do get in touch and we can talk a little more about your options.

What are TM44 surveys and are they compulsory?

Mon, 15 May 2023 20:00:47 GMT

Air Conditioning Energy Assessments are now a legal requirement under The Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007 SI 2007/991 amended by SI 2007/1669, SI 2007/3302 and SI 2008/647.

As your Maintenance provider we would like to make you aware of Legislation which is relevant to your site. It is a Legal requirement in the U.K to have an Air Conditioning Assessment, most commonly known as a TM44 inspection, carried out on Air Conditioning systems with more than 12kw of combined Cooling Capacity.

The inspections are required to be carried out in an independent manner every five years by a qualified assessor with a Government Accredited Certificate. The aim of the report is to look for energy saving opportunities relating to the system within the building. Sampling can be used depending on the make, model and age of the units on site. A site survey is carried out, an extensive report is compiled and lodged on the Landmark, a Certificate is issued valid for 5 years.

We are able to offer you TM44 inspections, if you wish to find out whether your building meets the threshold for this requirement please get in touch.

Planning Permission

Fri, 05 May 2023 21:34:18 GMT

Do I need Planning Permission to install Air Conditioning?

This is one of the most common questions we get here at Bedfordshire Air Conditioning.

In general, Planning Permission is not required for Air Conditioning units as long as the units are installed in accordance with the conditions set down under Permitted Development Rights. This means you won’t have to apply for planning permission but there are exceptions, for example;

If your house is in a Conservation Area, or in an Area of Outstanding Natural Beauty, or, if your house is a listed building.

So, what are the conditions of Permitted Development Rights?

The external unit is not installed on a pitched roof or a chimney breast
There is no wind turbine at the property
The external unit is not installed within 1 metre of the edge of a flat roof
The volume of the external condensing unit (the outdoor unit) is not more than 0.6m³
The condensing unit is more than 1 metre away from the boundary of the property
The condensing unit is sited at ground floor level
There is only one condensing unit on the property.

Whilst neighbours cannot complain to the council about the appearance or the aesthetic of your outdoor unit, they can do so on the ground of it being too noisy. This can be complicated to get right as noise levels are subjective so please do get advice from us at BAC on this matter.

How much does it cost to run an Air Conditioning system?

Tue, 25 Apr 2023 09:31:17 GMT

The cost of operating an air conditioning unit in the UK will depend on a number of factors, including the size and efficiency of the unit, the length of time it is used, and the cost of electricity in the area - this will take the form of a kW/hr tariff.

On average, it can cost anywhere from £50 to £300 per year to operate an air conditioning unit in the UK. However, this is just a rough estimate, and the actual cost will depend on the specific circumstances of the unit.

To get a more accurate estimate of the cost of operating an air conditioning unit in the UK, it's important to consider the following factors:

Size of the unit: Larger air conditioning units will typically be more expensive to operate than smaller units, as they require more energy to run.
Efficiency of the unit: Air conditioning units are rated using the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, the more energy efficient the unit is. Choosing a unit with a high SEER rating can help to reduce operating costs.
Length of time the unit is used: The longer an air conditioning unit is used, the more it will cost to operate. Turning the unit off when it is not needed can help to reduce operating costs.
The temperature setting you have your unit set on: generally speaking the lower the temperature setting, the more energy your unit will consume. The reverse is also true when your unit is in heating.
Cost of electricity: The cost of electricity can vary significantly depending on the area. In general, air conditioning units will be more expensive to operate in areas with higher electricity costs.

Overall, the cost of operating an air conditioning unit in the UK will depend on a variety of factors. By considering the size, efficiency, and usage of the unit, as well as the cost of electricity in the area, it is possible to get a rough estimate of the operating costs.

What Are The ‘F Gas Regulations’?

Fri, 14 Apr 2023 11:30:57 GMT

What Are The ‘F Gas Regulations’?

The F Gas Regulations are a set of rules in the UK that are designed to
reduce the use and release of fluorinated greenhouse gases (F gases), which
are potent contributors to climate change. The regulations apply to
businesses and individuals who use, handle, or release F gases, and they
set out a number of requirements that must be followed.

The main F gases regulated by the regulations are hydrofluorocarbons
(HFCs), which are commonly used in refrigeration, air conditioning, and
heat pump systems. The regulations require businesses and individuals who
use these systems to:

• Keep records of the amount of F gases they use and release

• Repair and maintain the systems in a way that minimizes the release of F gases

• Replace systems or parts that are likely to fail with alternatives that have a lower global warming potential (GWP)

• Recover and recycle F gases when systems are decommissioned or disposed of

• Train employees who work with F gases

The F Gas Regulations are in place for a number of reasons, including:

• To reduce greenhouse gas emissions: F gases are potent contributors to
climate change, and reducing their use and release can help to reduce
greenhouse gas emissions and mitigate the impacts of climate change.

• To protect the environment: F gases can have a number of negative
environmental impacts, including damaging the ozone layer and contributing
to air pollution. The regulations aim to minimize these impacts.

• To promote the use of alternatives: The regulations encourage the use of
alternatives to F gases that have a lower GWP, which can help to reduce
greenhouse gas emissions and the environmental impacts of these substances.

Overall, the F Gas Regulations are in place to reduce the use and release
of F gases in the UK, which are potent contributors to climate change. They
set out requirements for businesses and individuals who use refrigeration,
air conditioning, and heat pump systems to minimize the release of F gases
and to use alternatives with a lower global warming potential.

MVHR’s - what are they?

Wed, 15 Mar 2023 15:19:29 GMT

MVHR stands for "Mechanical Ventilation with Heat Recovery." It is a type of ventilation system that is used to provide fresh air to a building while also reducing energy loss.

MVHR systems work by drawing in fresh air from the outside and passing it through a heat exchanger. The heat exchanger captures the heat from the outgoing air and transfers it to the incoming air, warming it up before it is distributed throughout the building. This process helps to maintain a comfortable indoor temperature and minimise odours and humidity while also reducing energy loss.

MVHR systems can be used in both new and existing buildings. They are particularly useful in buildings that are airtight and energy efficient, as they can help to maintain good indoor air quality without compromising the building's energy performance.

There are two main types of MVHR systems: decentralized and central. Decentralized systems have a unit installed in each room, while central systems have a single unit that serves the entire building.

MVHR systems are a cost-effective and energy efficient way to provide fresh air to a building, as they help to reduce energy loss and maintain a comfortable indoor environment. They are also low maintenance and easy to operate, making them a popular choice for many homeowners and building owners.

Heat Pumps for Heating?

Wed, 15 Mar 2023 15:18:48 GMT

In the UK, gas boilers are being phased out as part of the government's plans to decarbonize the heating sector and reduce greenhouse gas emissions. The goal is to transition to low carbon heating technologies, such as heat pumps and district heating systems, which emit significantly less carbon dioxide than gas boilers.

Under the government's Heat Networks Investment Project (HNIP), funding is being provided to support the development and expansion of heat networks, which use central boilers or other low carbon heat sources to provide heat to multiple buildings. The goal is to have 30% of heat demand met by heat networks by 2030.

In addition, the government has set a target for all new homes built after 2025 to be "zero carbon," which means they will produce as much energy as they consume and will not be connected to the gas grid. Instead, they will rely on low carbon heating technologies, such as heat pumps, to meet their heating and hot water needs.

It's important to note that while gas boilers are being phased out in new homes, they will still be allowed in existing homes until they reach the end of their lifespan. There is no specific date for when gas boilers will be banned in the UK.

Overall, the government's plans to phase out gas boilers are part of a wider effort to decarbonize the heating sector and reduce greenhouse gas emissions. This will require the adoption of low carbon heating technologies and a shift towards heat networks and other decentralized heating solutions.

Air Conditioning

Wed, 15 Mar 2023 15:17:03 GMT

Air Conditioning is a popular feature in homes and businesses in the UK, particularly in the warmer months of the year. It provides a comfortable and controlled environment by regulating the temperature and humidity of a space.

The main type of air conditioning systems in the UK are 'split systems'. Split systems consist of an indoor unit that is installed inside the building, and an outdoor unit - the correct name being a Condensing Unit - that is installed outside. These systems can be expensive to install, but they offer efficient cooling, and heating, and are quite unobtrusive.

Air conditioning systems work by drawing in hot air from the room and passing it over a refrigerant, which circulates throughout copper pipes called an evaporator coil, and which absorbs the heat and cools the air. The cooled air is then blown back into the room, while the heat is released outside through the condensing unit.

In the UK, air conditioning units are rated using the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, the more energy efficient the unit is. It's important to choose an air conditioning system with a high SEER rating, as it can save money on energy bills in the long run. Units may also have a COP (Coefficient Performance) rating and this can also be used to decide energy efficiency.

Air conditioning systems can be used to cool and dehumidify a space, as well as to heat it. In the UK, air conditioning systems that can heat a space are known as "reverse cycle" or "heat pump" systems. These systems work by reversing the flow of the refrigerant, allowing them to extract heat from the outside air and bring it into the building via the indoor unit.

It's important to properly maintain an air conditioning system to ensure it runs efficiently and effectively. This includes cleaning or replacing the filters regularly, checking for and sealing any refrigerant leaks, and having the system serviced by a professional on a regular basis.

Overall, air conditioning is a convenient and effective way to regulate the temperature and humidity in a space in the UK. By choosing an energy efficient system and properly maintaining it, it can provide comfortable and controlled indoor environments all year round.

VAT 2022

Wed, 15 Mar 2023 15:16:30 GMT

During the recent Spring Statement, Chancellor Rishi Sunak announced that the VAT rate which applies to the installation of a/c systems in domestic/residential properties will be 0%

This replaces the previous rates of 5% and 20% which have applied over the past few years. In fact, it introduces some much needed clarification to this topic as many have struggled with the previous HMRC advice which has not been clear at all and open to interpretation, and therefore error.

So, any a/c system which is installed after 1st April 2022 in a domestic or residential property will be charged at 0% provided the invoice is paid for by an individual - as opposed to a company or charity or public sector organisation - and, crucially, the system must be able to heat as well as cool. This is because a/c units are Air Source Heat Pumps and it is this very efficient technology which the government is keen to increase the uptake of among households.

If the idea of almost instant and energy efficient heating or cooling isn’t enough for you, if the idea of filtered and treated air circulating throughout your premises isn’t enough for you, if the idea of a stylish and fashionable unit which complements your decor isn’t enough for you….. then maybe a VAT free invoice at the end of the job might finally convince you to have a/c installed?? We all like a bargain and this certainly sounds like one to us!

Go on; what are you waiting for??

R32 Refrigerant

Wed, 15 Mar 2023 15:15:55 GMT

Most end users don't know - or care - what refrigerant their equipment uses. But they should. With the continuing rising cost of R407C and R410A, which have been the mainstays of air conditioning refrigerant for the last 20 years or so, maintaining existing air conditioning equipment is becoming increasingly more expensive for systems that are no longer considered up to date. R32 refrigerant is being used as their replacement and most, if not all, manufacturers now use R32 in their latest ranges of equipment. So why is R407c and R410a refrigerant becoming so expensive and what can you do about it?

Legislation

Well, the requirements of the 2014 EU fluorinated greenhouse gas (F-gas) regulations, which include the phasing out of HFC’s, means that manufacturers need to not only reduce refrigerant emissions in their systems but also make them increasingly more energy efficient.

Advancing heat exchanger technology, improved design and manufacturing processes, more rigid preventative maintenance all aid the overall aim, but the most important element is utilising refrigerant with a lower GWP (Global Warming Potential).

From 2009 to 2012 HFC sales in the EU averaged 183 million tonnes of carbon dioxide equivalent a year. This provides the baseline for the phase down which will be enforced on to the EU market every year until 2030 and, incrementally, less and less HFC refrigerant such as R407c and R410a, will be available. Already we have significantly less refrigerant available to the market, as you can see below

Would an R32 system be right for you?

Of course, R32 has many advantages in that its a high pressure refrigerant, with lower GWP and ODP ratings than its ancestors. It's efficient, its cheaper than the older refrigerants and it's likely to be on the market for along time to come. However, it can not be used as a 'drop in' refrigerant; that is to say, you can't simply remove the old refrigerant and insert R32 in to an existing system. R32 is slightly flammable under the right conditions so great care must be used when handling it and, importantly, when designing a system which uses it. Bedfordshire Air Conditioning recommends that all old, failing or redundant equipment be replaced with new equipment specifically designed to operate on R32 refrigerant.

F-Gas News: F-gas violators face £200,000 fines:

Wed, 15 Mar 2023 15:13:22 GMT

After receiving support from the industry, the Fluorinated Greenhouse Gases (Amendment) Regulations 2018 were laid before the UK Parliament on Tuesday, 30th January. Subject to the expected approval, they will come into force within the next few weeks and enforcement bodies will be able to apply civil penalties from April 1. Wales and Northern Ireland have decided not to adopt civil penalties at the moment.

The new civil penalties would apply to a range of F-gas contraventions. The deliberate release of F-gases would remain as a criminal offence but there would still be the option to apply a civil penalty in such cases instead.

The maximum fine of £200,000 could be applied to offences such as the intentional release of F-gases to atmosphere, breaches of the quota limits for placing HFCs on the market, and failure to comply with an enforcement notice.

Fines of up to £100,000 are proposed for less serious offences, such as contravening requirements and procedures for minimising emissions or leakage and recovering F-gases from equipment. It would also be levied on non-F-gas certified individuals handling F-gases or on those not fulfilling the requirements to register for and verify quota usage.

A maximum fine of £50,000 could be applied to breaches including failing to correctly label equipment, failing to comply with the requirements for declarations of conformity for importing products containing F-gases and failing to keep records of F-gases used in equipment or F-gas sales.

More minor breaches such as not reporting within the prescribed deadline on F-gas production, import, export, destruction and feedstock usage could carry a maximum fine of £10,000

Non-complying companies and those who use 'cowboy' companies should take note!

Global Warming Performance

Wed, 15 Mar 2023 15:12:34 GMT

According to 2014 EU F-Gas Regulation (517/2014), EU countries must reduce the Global Warming Performance year by year. This regulation defines how each industry needs to contribute to reach the total EU target.

In the air conditioning industry, this will affect single split air conditioning systems containing less than 3kg of fluorinated greenhouse gases - that is to say the split systems in most peoples offices, shops and homes. The refrigerant within this system must be less than 750 global warming potential (GWP) by the year 2025. Most manufacturers are ready now to supply any kind of single split and multi split system with up to five ports, in addition to commercial splits of up to 14kW so this should present no problem.

For many years, R32 has been used as a component part of the R407C and R410A refrigerant blends. On its own, however, R32 offers a number of significant advantages over blended refrigerants.

First, R32 has a much lower impact on global warming when compared to its blended predecessors - its GWP is significantly lower than that of R410A. When considering future legislation and the anticipated reduction in the availability of refrigerants, plus a drive towards the use of lower GWP refrigerants, it makes sense to start to use R32 systems for all new projects going forward.

R32 is also a more efficient alternative to R410A, with realistic efficiency increases of up to 10 percent, leading to significant energy savings for building services managers and end users.

As R32 is already a familiar component of R410A, the switch does not present any new challenges to installers procedures, including piping and testing, which remain the same. As with all refrigerants, R32 must be safely handled at all times and spaces properly ventilated when it is being charged and recovered from air conditioning units. R32 is mildly flammable and must be handled by F Gas certified engineers but this is true of all refrigerants on the market currently anyway.

In conclusion, the reasons why Bedfordshire Air Conditioning has decide to select and specify R32 systems going forward is;

- lower GWP rating

- cost neutral compared to R410a equipment

- more energy efficient than R410a equipment

- lower ODP rating

- cheaper refrigerant for servicing requirements

- more sustainable refrigerant in the long term.

We anticipate R410a refrigerant playing its part in air condition landscape for a few years to come but expect that this refrigerant will be phased out in the main within the next 2 to 4 years.

Heat recovery ventilation

Wed, 15 Mar 2023 15:11:56 GMT

If you’ve followed the news at all over the past few months you will have noticed all the items focusing on air quality and in particular the harmful effects of pollution leading to a major public-health crisis. It is estimated that 9,000 people in London alone are dying prematurely each year because of long-term exposure to air pollution. For the whole of the country the estimate is that it is up to 40,000 people a year.

According to the Building Research Establishment (BRE), exposure to air pollutants also depends a lot on our exposure to indoor air and when we spend an estimated 90 per cent of our time inside buildings, then we really need to ensure that they are able to provide a respite from the toxic outdoors and deliver a fresh and comfortable environment.

At the same time, we all need to ensure that our homes are as energy efficient as possible, not only to help combat rising fuel prices, but also to protect the building fabric by reducing the chances of condensation and mould thereby reducing maintenance requirements.

So how can you introduce fresh air into a home without letting bad air in, or heated air out?

Heat recovery ventilation

Mitsubishi Electric has led the way on what is known as Mechanical Ventilation with Heat Recovery (MVHR) in the commercial sector with its popular Lossnay system and the manufacturer has now translated all of this technical know-how into an easy-to-fit unit that is an ideal and cost-effective way of introducing MVHR, room by room.

“We’ve worked with customers to introduce full Lossnay systems but this can involve major refurbishment work for existing buildings as it requires ducting throughout a property so whilst this works really well for a huge number of properties, there are some that need a more straightforward solution. ” explains Janvi Patel, ventilation expert for the Hatfield-based company.

“Our new VL-50 Lossnay unit can be fitted to an outside wall and ducted out using one single pipe, and will then capture up to 84% of the heat energy that would otherwise be wasted.”

Lossnay achieves this by using a fine paper core, which allows the heated outgoing air to transfer this heat energy to bring the incoming air closer to the room temperature, thereby keeping the inside fresh without wasting energy. Pollutants, smells and even outdoor noise are filtered out by the unit, meaning that the inside is both fresh and comfortable, whilst the heat recovery element also means it is highly energy efficient.

Easy to fit

Only one single pipe connection to the outside is needed for the unit, making it ideal for retrofitting into existing buildings. The VL-50 is available as a pull-cord, hard-wired, or wireless remote controlled unit and measures just 52cm by 24.5cm. The unit can be fitted vertically or horizontally to suit the interior décor and provide installation flexibility and needs no pipework other than the connection through the wall to the outdoors.

“Lossnay recovers both latent heat and sensible heat, meaning the incoming air is comfortable and the home doesn’t suffer from static or dryness,” adds Patel, “it’s all about increasing the comfort whilst minimising the energy needed to do so.”

The added advantage is that adequate effective ventilation is known to help reduce instances of condensation which can lead to mould and mildew. These are also harmful to health and, if left untreated, damaging to the fabric of the building. With low sound levels, low power consumption and easy maintenance, the VL-50 provides a quick and easy way to introduce highly energy efficient, heat recovering ventilation to existing properties.

“The overall outcome of course, is providing comfortable, fresh temperatures inside homes whilst also providing protection from rising air pollution.”

Refrigerant rocketing prices

Wed, 15 Mar 2023 15:10:33 GMT

Most people would know that refrigerant, or 'gas' as it's known, is an integral part of a refrigeration or air conditioning system; it's the fluid which gets pumped around the system allowing your system to cool or heat your room. Some of you will know also that refrigerant prices have sky-rocketed over the last 12-14 months. Why though?

Put simply, the large increases we are now experiencing are down to the good old fashioned ‘supply & demand’ dynamic. One of the major components used in the manufacture of some refrigerants are Hydrofluorocarbons, more commonly known as HFCs. These HFCs contain a high GWP (Global Warming Potential) and, as a result, are being forced out of the market place under the government’s phase-down of HFCs. So as supply drops and demand continues, prices rise.

Our supply partners have had their HFC quota cut by 40% in 2018 so certain refrigerants, particularly R410a & R407c, will be in short supply. Like anything that is scarce, it comes at a cost!

Our recommendation; use R32 refrigerant for new installations instead of R410a and tighten up on your leak testing as part of your maintenance regime as, in this instance as well as many others, prevention is better than the cure!

Autumn Servicing

Wed, 15 Mar 2023 15:06:39 GMT

The summer has gone and autumn has well and truly settled in. You might think your #airconditioning units can be forgotten about for a few months and you can start thinking about turning your units back on again in the spring.

The fact is though that most air conditioning units continue to operate over the winter; this is true for units which cool server rooms & comms rooms etc as well as systems which serve shops, offices and even homes because these systems also provide heating in these cooler months - this is the reason why these units are called #heat pumps !

As the leaves fall and the winds pick up, leaves and other materials can gather around your outdoor units causing failures, which can be expensive to repair, or can cause your system to run inefficiently, delivering you less comfort and costing you more to run. Damp or wet leaves and further debris building up around your #condensing unit can cause mould and mildew to build up too, potentially clogging up your coil. If your system operates on #heating, then the outdoor unit will go in to defrost mode often and this 'melt' water may cause leaves etc to clog further around your condenser coil.

Why not let Bedfordshire Air Conditioning give your air conditioning systems a winter service? Contact us today!!

TM44 Air Conditioning Inspections

Wed, 15 Mar 2023 15:05:27 GMT

TM44 – what is it and how does it impact me?

TM44 is the CIBSE document which is used as a guidance note to comply with the Energy Performance of Buildings Directive (EPBD) within the UK. This relates to inspections of Air Conditioning systems within buildings.

Which systems require an air conditioning inspection? Well, buildings containing air conditioning systems with an overall rated output of more than 12kW must comply and have a TM44 inspection. Note: this isn’t just if you have a unit over 12kW – this is cumulative so if you have 3 units rated at 5kW, you must have a TM44 inspection as your overall rated output is 15kW. If you have any doubts as to how to calculate this rating, please do get in touch as we’re happy to assist.

Increasingly, companies who want to achieve ISO accreditation, specifically ISO 14001 and ISO 18001, are requiring TM44 inspections. Many are surprised to learn they are in fact not compliant presently. Failure to show a TM44 certificate can jeopardize your ISO accreditation, as well as landing you a substantial fine.

With air conditioning systems in a typical building being responsible for up to 40% of energy consumption, the reasons for knowing how efficient your systems are is not just a matter of compliance.

Your inspection report will show you improvements you can make to your systems to make them more efficient and this may include replacing them completely – to take advantage of energy efficient inverter compressors, EC or digital motors, higher pressure and more efficient refrigerant and modern units with higher COP’s and SEER’s and more efficient heat transfer properties such as high efficiency coils. Often it might be a recommendation to have your coils thoroughly cleaned, or advice on how to set your controller up to prevent out of hours operation, or perhaps just adjusting your set-point.

Whilst it is a legal requirement to have an inspection undertaken, it is not a legal requirement to undertake any of the recommendations noted in the report. Be aware though, the person who controls the operation of the system – not the person who adjust the set-point from time to time but the person who controls the technical functioning and operation of the system – is responsible for ensuring this inspection takes place. Enforcement of TM44 inspections lies with Trading Standards Offices in your local area. If your system is non-compliant, the person responsible for the technical functioning may be liable for a personal fine.

Best to be compliant we say here at Bedfordshire Air Conditioning!

Heat Stress

Wed, 15 Mar 2023 15:04:24 GMT

So; with the forecast and much-anticipated heat wave now upon us, it's fair to say that not all people are looking forward to it. Those who have to work in hot and humid conditions will be suffering rather badly and being too hot can be very much like being too cold; it's debilitating, demoralising, uncomfortable, unproductive and, in extreme cases, potentially dangerous. This is true for staff and customers alike.

What is heat stress then? Stress occurs when the body's own means to control its core temperature starts to fail. The H.S.E says heat stress may affect a company at any time of the year but there is an increased risk during the warmer months of summer. This is because it's not just the season which can affect the human body and cause Heat Stress; other contributing factors are also Humidity, Work Rate and Clothing, as well as air temperature.

Ok; so what are the effects of Heat Stress? Well, like many things, individuals have different tolerances and thresholds and different circumstances will affect different people in different ways. Typical symptoms are; heat rash, muscle cramps, moist skin, an inability to concentrate, fainting and also heat exhaustion. An individual may also experience fatigue, headache, giddiness and nausea. In more serious cases, one may be affected by heat stroke, including confusion, convulsions and - in extreme cases - loss of consciousness.

What can be done about Heat Stress? Like all things, prevention is better than the cure. If working practices can be changed to take in to account the hotter conditions, then they should be. Sensible procedures should be put in place regards staff uniforms or dress standards; for example blazers, long sleeve shirts, ties and long woollen skirts are not ideal! If barriers can be put in place to block or reduce radiant heat or solar gain, such as window tinting or screens, then this is also a good idea. Creating air movement, via fans or natural ventilation, is a low cost option and often of immediate benefit. Engineered solutions such as ventilation systems and air conditioning systems can offer a controlled and measurable approach to reducing the temperature and removing heat stress.

Most offices and buildings can have modern air conditioning systems installed these days and we'd be only too happy to assist you with a design and proposal for your particular application.
