What size air conditioner do I need?

Having air conditioning installed is a worthwhile investment, a significant expense, and a decision that requires careful planning.

You may already have done some research yourself, perhaps you’ve looked at how air conditioners work, and which size and types you favour. There may be some features that you consider are important, such as running costs, aesthetics, or smart technology.

However, bad choices can lead to disappointing results, and soaring energy bills, something we that all wish to avoid. In this article we explain why buying an air conditioner with the correct output, should be top of your list, and a crucial part of the selection process.

Does size matter?

Yes, we know it’s a cliché, but size matters. In fact, it is the most important consideration.

An air conditioner that’s too small will not heat or cool your room effectively, and one that’s oversized will be inefficient and expensive to run. It important that we first establish that size in terms of physical dimensions, and size in terms of output, are two separate entities.

From now on we want you to think of size as your unit’s ability to produce cool and/or warm air. In this industry we measure size in kW (kilowatts), and sometimes BTU (British Thermal Units).

Simply put, size is all about output, or in technical terms, the duty. The duty has a direct impact on how your AC system will perform in terms of efficiency and running costs.

Bigger is not necessarily better

A unit that is oversized for an area can put too much pressure on the system’s components. It will be costly to run, and costly to repair, if your system packs up.

Physical size doesn’t indicate the efficiency or power of a unit, technology advancement means that some of the smaller more compact designer air conditioners can offer much more than the older bulkier systems.

An oversized system will stop and start more often. This is not energy efficient and will lead to increased energy bills. Not only that, but you will also struggle to maintain an optimum temperature and will often find that the room is too hot or too cold.

The correct size ac unit will effortlessly keep your room at the optimum temperature.

Undersized unit = oversized bills

An undersized AC unit will need to run constantly, and will not be powerful enough to reach, and maintain, the optimum room temperature. This will mean higher energy bills. An undersized unit that is having to work too hard, can also hit your wallet hard in terms of maintenance costs, and could result in your unit having premature wear and tear, breakdowns and a shortened life span.

Other factors that will affect size …

There are several variables to consider that will impact selection of the duty (kw or BTU) of an air conditioner:

How well insulated is the building?

Adequate insulation directly affects the efficiency of your air conditioner, if you do not have a well-insulated property this will need to be considered when calculating kw size. Poorly insulated homes or workplaces may require an AC system with a higher output.

Is the room south-facing?

South facing rooms are exposed to more sunlight and heat, which means that you will have more heat gain. Your AC system will need to work harder to keep south facing rooms cool and you would need to make additional allowances in your calculations for this.

How much of the external walls are made of glass?

The size and orientation of the windows is especially important. South facing windows result in high solar gain which will be taken into consideration when calculating KW/ BTU size. You may need a more powerful unit.

Where is the room located?

Warm air rises, so an air conditioner in a loft space will need more cooling capacity than a ground floor room.

Is there electrical equipment within room?

Rooms such as comms rooms or entertainment rooms contain heat generating electrical equipment, and this increased need for cooling will need to be catered for when choosing the size of your air con unit or units.

Is the room an above average height?

A room with a high ceiling has much more volume than a room with a standard ceiling height and a larger unit may be considered more suitable here.

How to calculate the correct size …

Use our simple calculator to estimate the correct size air conditioner for your room

    This calculator uses the simple formula of 125 watts of cooling per square metre to estimate the best size for your space, however it is important to remember that there are other variables (such as those above) that will need to be factored in.

    Always round up to the nearest 0.5kw

    This is for estimation purposes only; a qualified engineer will be able to tell you the exact size for your individual requirements.

    Here is an example of how to estimate AC size for a room …..

    A room that meets standard criteria of 5 metres in width 7 metres in length which gives me a total area size of 35m2. Based on 125 watts per square metre I would need a minimum of 4.375kw of cooling.

    Simply …
    5 x 7 = 35 x 125 = 4,375 (watts)

    Air conditioning unit size required = 4.5kw or around 15,300 BTU. Click below to see BTU to KW conversion chart.

    How much does air conditioning cost?

    2Fez6PZRqWs7fM4dXM2c AdobeStock 20283529

    Commercial installations

    Each commercial air con installation will present with entirely different heating and cooling requirements.

    To meet these diverse applications there are a range of air conditioners available with different set ups and layouts, from single split systems to complex VRF or VRV systems.

    As one size does not fit all, it would be difficult for you to estimate the cost of your installation. Therefore, it is essential that you enlist the expertise of an experienced and accredited AC installer, who will confidently identify your needs and design a tailor-made air con system to fit your individual circumstances perfectly.

    Domestic installations

    Firstly, use our size calculator to estimate the size unit you will require. Then refer to the table below to get an idea of your air conditioning cost of installation.

    Remember when considering size, it is important to consider the different variables listed above.

    This table is for estimation purposes only, the final price of your install will be dependent on which manufacturer you choose the pipe run (distance from indoor to outdoor) and which type of unit you opt for (e.g. wall mounted, ducted).

    Why Does My Air Conditioning Smell Bad?
    8 Reasons and Fixes

    air conditioning66

    If you notice an unpleasant smell coming from your air conditioning unit, your ductwork, or your surroundings are not smelling as fresh as they should, it could be a sign that your air con system needs attention.

    We have consulted with a qualified service and maintenance technician, as to what are the most likely causes.  Drawing from his many years of experience in the industry, in this article we discuss eight of the most common aircon smells that are reported, and how best to tackle them.

    uvdSq6Xfed9KQwLrQFvS air con picture1

    1. Burning/Electrical Smells

    1aircon

    Your air conditioner contains many electrical components, and a malfunction of one of these could present a fire risk.

    If you smell burning, this could be down to an ELECTRICAL FAULT. Switch off your unit and contact your AC professional URGENTLY.

    Never attempt to solve a burning issue yourself, you will be putting yourself at risk of serious injury. This problem is one for the experts only.

    Not all burning smells are hazardous, a slight burning smell could be a result of dust burn off if you have not used your aircon for some time. However, we would still recommend that you SWITCH OFF AND SEEK ADVICE before assuming that this is the case.

    BE PROACTIVE. There are steps that you can take to prevent air conditioning fires and being proactive is the best way to protect yourself, your loved ones, or colleagues.

    Never obstruct your air conditioner. Never store flammable materials nearby. A thorough, comprehensive, and regular service by a specialist engineer will ensure that your equipment is clear of debris, functioning properly, and any early signs of wear and tear will be picked up, and dealt with, before they cause a serious issue.

    2. Damp, mildew or mouldy smells

    2aircon

    What causes the damp, musty, wet socks or rotten wood smells coming from your air conditioner?

    The build of up of human and pet dead skin cells and hair may sound harmless enough, however these particles provide a perfect breeding ground for any bacteria, mildew and mould in your AC unit.

    Contained within your air conditioning unit is a filter. Its main function is to prevent dust, hair, dirt and other particles from reaching the components in your system. If your filter becomes clogged by the build-up of these unwanted particles, then the bacteria and mould that thrive in this environment will quickly multiply.

    This bacteria and mould release an unpleasant odour, that your air conditioner will then circulate around your room. The spores from the mould, and bacteria, can also be circulated, potentially putting your health at risk.

    The filter in your aircon unit also helps to reduce the presence of dust mites, allergens, and pollutants, which can cause asthma attacks or respiratory illnesses, another reason why regular cleaning is very important.

    A service by a professional will keep your home, or working environment, free of unpleasant smells, and will help to make it a healthier place to be too.

    For domestic installations it is advised that your air con is thoroughly cleaned and inspected by a specialist once a year. For commercial installations, twice a year is recommended. This process involves stripping back the filter, fan scrolls, coils and cases and cleaning with specially formulated products.

    3. Rotten Eggs (refrigerant leaks and dead animals)

    3aircon

    Concerned that the rotten egg/sulphur smell coming from you aircon could be a refrigerant leak or a dead animal?

    Refrigerant Leaks

    AC systems manufactured prior to 2010 contained R22 (Freon) refrigerant, which if leaked, gave off a sulphur smell. So, if your unit is an older model, and you can smell rotten eggs, we would advise you contact your AC specialist immediately.

    R22 has now been banned because of its negative impact on the environment. AC units manufactured since 2010 use R410A, and more recently, R32 refrigerants, both are virtually odourless.

    This means that a smell of rotten eggs is unlikely to be the smell of leaking refrigerant coming from your air conditioner itself. We would advise you to investigate your surroundings, as any smells near to your air conditioner, are likely to be recirculating.

    A rotten egg, gas or sewage smell could be a sign of a problem with your drains or plumbing, or could be an indication of a faulty gas appliance, in both instances we advise you seek professional advise immediately.

    Finally, if you are still concerned that you have a refrigerant leak, get in contact with your AC specialist as soon as possible.

    Dead animals

    In ducted AC systems used in larger domestic and commercial installations, it is possible for a small animal, such as a bird or mouse, to enter your AC system via the ducts, and then perish. The decomposing remains will give off a pungent smell, which will then be circulated around your air space.

    These animals could also be carriers of bacteria and viruses, which could pose a threat to health, another reason why this issue needs to be acted upon promptly.

    Locating and removing the decaying carcass is a challenge that is best addressed by a professional. Once the animal has been safely disposed of, specialist products will be used to completely clean and sanitise the area.

    4. Chemical aromas

    QWMlPBZEVhsbIbCR9IGh AdobeStock 150196363

    Remember that an air conditioning system is designed to circulate air around your room. If you air con unit is situated alongside an area where there are odours, then these will also be circulated. Cooking smells usually tend to dissipate quickly but chemical smells including scented cleaners or bleach, and cigarette smoke, can get trapped in the unit, and will be obvious in the air for much longer.

    In larger commercial buildings this will be less of a problem as ventilation systems are frequently installed enabling fresh air to be supplied, and stale air to be extracted, along with any odours.

    The careful planning of the position of your unit is important, and your AC specialist will advise you on which type, and position is best suited to your needs.

    5. Vinegar

    oSubPWek2s6mPmqzqYGn AdobeStock 403616840

    As we have discussed before, an air conditioner that is in need of a service or has been left unused for a long period of time (perhaps over the winter), could be harbouring some rather repulsive odour releasing bacteria and mould.

    In this warm, moist environment these offensive micro-organisms will happily thrive and can omit an acrid odour that many people describe as a vinegar smell.

    A vinegar stench should be investigated as soon as possible, as it could be an indication that harmful spores are present and are being circulated around your living or working area, putting your health at risk.

    It is advisable to call in a professional to pinpoint the exact cause of the offending smell and decide on the best method to eradicate it. In a domestic situation the bacteria and mould could be located within the unit itself and in larger installations or commercial settings this could within the ductwork. Excess moisture or a clogged filter could also be the culprit.

    A regular deep clean and thorough check over by a qualified AC engineer, will keep your system operating as it should, and help ensure that the air you breathe is not harmful to your wellbeing.

    6. Fishy smells

    3vwDlSWNCfR4xLsLhUhV AdobeStock 310826845

    As with burning and electrical smells the smell of fish coming from your air con is potentially a fire hazard and a situation that requires URGENT ATTENTION.

    Before reading on we would recommend you immediately SWITCH OFF your air conditioner and SEEK ADVICE from an AC professional.

    It is a common misconception that these fish odours could be down to bacteria and mould, or perhaps a decaying animal, but in fact the most common cause is due to OVERHEATING OR MELTING PLASTIC. When a component becomes faulty the plastic within can become extremely hot. The melting or burning plastic will emit a fish smell that will be circulated around you living area or workspace.

    This said, your AC system contains a circuit breaker, which is a safety switch that protects your equipment from damage by turning off the power when an overload or malfunction is detected. It also protects your safety since overloaded circuits can result in a fire. This means that your system should automatically switch off should there be a fire risk, however we would still advise that if you can smell fish or burning, you immediately switch off your air con as a precaution, it is better to be safe than sorry. It may be that the odour is being circulated from elsewhere in the room/building, potentially a faulty electrical appliance elsewhere, and this will need investigating further.

    If you detect fishy, electrical or burning smells coming from your air con system, do not attempt to identify the cause of the problem yourself, you will be putting yourself at risk of serious injury. This problem is one for the experts only.

    The regular servicing of your AC system will ensure that your air con is functioning properly. An experienced engineer will be able to detect any early signs of a faulty component and will be able to repair or replace it before it becomes a serious hazard.

    7. Stinky feet

    7aircon

    A distinctive smell that may have had you looking around accusingly at your family members or work colleagues!

    However, the odour of sweaty or smelly feet could be coming from your AC system itself, and could be a sign of a grimy, clogged up air con, dirty coils or even a blocked condensate drain, there are many possibilities. This offensive stench will be circulated throughout you home, or workplace and the grime or blockage could cause your AC to run inefficiently. But there are more important issues that avoiding regular servicing could present…

    Excess moisture and unwanted particles inside your air conditioner can also lead to the growth of mould, mildew and bacteria and along with this there is the potential for harm to your health.

    A service visit really is the best option for this offending smell, as an experienced engineer is best placed to identify and fix the issue. Regular service and maintenance will prevent unwelcome stenches and ensure that your system is performing at its very best.

    8. Urine

    EUIRKtc3a4XGej2XDSYr AdobeStock 434924013

    As we have covered in previous points neglecting to regularly service your AC system will result in the presence of mould, mildew and bacteria.

    These micro-organisms will thrive happily within your air conditioning system, inside the coils, filters, and ductwork etc. In this damp, warm environment, they can multiple quickly, feeding off the trapped dead skin cells, hair and grime that can build up there over time.

    One odour that we commonly hear reported is that of urine.

    Moulds and bacteria are toxigenic, which means that they can produce toxins – specifically mycotoxins. If you detect a smell of urine, it means that these airborne toxins are not only present, but are being circulated around your home or workspace and potentially putting your health at risk.

    We would advise you to seek professional help as soon as possible. A qualified AC engineer will be able to quickly locate the problem, and eradicate the smell, using specialist equipment and cleaning products.

    A final word on smells …

    We have uncovered the most popular, or should we say unpopular, smells that you may detect coming from your air conditioner. You should now be able to sniff out their root cause and have a basic understanding of why this is happening.

    In simple terms, the odours that you can smell are either coming from your air con unit itself, from your AC systems ductwork, or are existing smells in your surroundings, that are being circulated.

    An air conditioner is a worthwhile investment, and it will help to keep your living or working environment comfortable for many years, but like most things mechanical, it needs regular service and maintenance, not only to keep it working safely and efficiently, but to also highlight any signs of wear and tear that need attention.

    Remember, prevention is better than cure, a badly maintained aircon system could result in the unexpected cost of an emergency repair. It could also be putting the health and safety of your loved ones, or colleagues, at risk.

    Always consult an expert if you notice anything untoward about your air conditioner, and never attempt to fix any of the issues of aircon smells yourself, unless you are qualified to do so.

    If you would like any further advise on how to deal with AC smells, or if you would like to speak to us about the installation, maintenance, or emergency repair of an AC system in your home or workplace, please contact our specialist team at Evergreen Air Conditioning Limited.

    HOW DOES AIR CONDITIONING WORK?

    Whether you are looking to install a large multi-unit system for your office space, or you are looking for a small unit for your home, the main principles of an air conditioner are the same.

    Of course, your specialist aircon installer will be happy to spend time with you, explaining in detail how to operate your AC system, and this will be set up and customised for your personal requirements.

    But with so much information to take on board it can be very confusing, so here we have compiled a simple guide, broken down for you to read through in your own time.

    THE COMPLEXITIES OF YOUR AIR CONDITIONER BROKEN DOWN

    An air conditioner is used to create and maintain an optimum temperature, and humidity level, in a building. It also contains an air filtration system that reduces allergens and pollutants.

    To understand how an AC system works, it is easier to think of it as two separate sides, a cool side and a hot side, located in indoor and outdoor equipment, respectively. These two sides are linked together by a series of refrigerant filled pipes that form part of a continuous cycle.

    This is known in our industry as a split system.

    A window unit, or through wall unit (mainly used in America, you may have spotted them on the TV), work using the same principles as a split system, the only difference being that both the hot side and the cool side are located within the same piece of equipment.

    air conditioning 2 1

    IT’S ALL ABOUT THE SCIENCE

    In order to cool indoor air an air conditioner uses refrigeration. Utilising the simple law of physics, the refrigerant that is circulated in the air conditioner is a liquid which absorbs heat when it converts to a gas. This process is called phase conversion. A system of coils are used to force the refrigerant to convert between gas and liquid (evaporate and condense) and vice versa, in order to cool the inside temperature of your building and expel unwanted heat to the outside atmosphere.

    THE COOL SIDE

    The indoor unit contains an evaporating coil. When warm air from inside the room is blown over the low-pressure evaporator coil, via the indoor unit(s) built in fan, the refrigerant liquid inside the coil absorbs the heat and transforms to gas. Fans within the air conditioner then circulate the now cooled air to wherever it is required inside the building. This can be direct from an ‘on show’ air conditioner or via a hidden air conditioner i.e., above a ceiling which is then ducted via ceiling grilles.  Both systems will give the same results however the ducted options are normally preferred as this finish is more aesthetically pleasing.

    air conditioning 4

    THE HOT SIDE

    To carry on the cooling process the system now needs to convert the gas back to a liquid again. A compressor, which sits outside the building, inside a condensing unit, puts the gas under high pressure and this process produces unwanted heat. The unwanted heat is expelled to the outside atmosphere with the help of the condenser coils and an exterior fan (also located within the condensing unit).

    air conditioning 5

    TWO SIDES WORKING IN PERFECT HARMONY

    The refrigerant in liquid form is transported back to the evaporator where the whole process starts again. A continuous seamless cycle where liquid refrigerant, coverts to gas, absorbs heat, is compressed and returns to liquid again.

    air conditioning 6

    VRF/VRV Systems – simultaneous heating and cooling

    If your AC unit is a combined cooling and heating system, the above processes we have explained are simply reversed. To achieve this a reversing valve is all that is needed.  This valve reverses the flow of thermal energy, changing the direction that the refrigerant travels through the system. The hot condenser coils have now become the cold evaporator coils, and vice versa. Warm air is pumped into the room and the cold air gets expelled outside.

    hLQGiSgYj76IE0DL7fho AdobeStock 173671860

    AND FINALLY….

    Three other components that you may have heard mentioned are thermostats, filters and expansion valves. In simple terms, this is what they do….

    Thermostats

    To set your room to a desired temperature you will need to use a thermostat. The air conditioner will continue to cool air until the sensor in the thermostat detects that the room has reached the correct temperature. The sensor will then detect when the temperature begins to rise, and once again power up the air conditioning unit.

    QeRgcX8UqFvPLUsrTZyz Thermostat

    Expansion Valves

    In this article we have learnt that there is a direct relationship between pressure and temperature. An increase in pressure produces an increase in temperature. The expansion valve restricts the flow of the high-pressure liquid refrigerant from the condenser, and controls how much can pass into the evaporator coil. By restricting the flow, the refrigerant has more room to expand in the coil. The expansion causes the pressure of the refrigerant to rapidly drop, and this also causes a drop in temperature.

    E9JgJhXAmmkw35j2KRC4 expansion valve

    Filters

    As important as maintaining a comfortable room temperature, is the quality of the air that we breathe in.

    The filter cleans the air that circulates through air conditioning system. Unwanted contaminants and particulates present in the inside air, such as mould spores, bacteria, dust particles and allergens, will be trapped in your air conditioners filter.

    To ensure that this part of your AC system is working properly, it is of upmost importance that they are cleaned, or replaced, regularly. This is advised to be carried out by a specialist qualified air con installer, as other issues which may occur will be spotted and dealt with correctly, such as chemical coil cleans and other items.  This will also uphold manufacturers warranties and increase the life expectancy of each system.

    air conditioning 7

    Hopefully, we have now answered your question ‘how does air conditioning work?’. Of course, there are many different types of complex, highly efficient systems out there, for different types of application, so to choose the correct system for your situation calls for specialist knowledge in this field.

    WORKING FROM HOME …. KEEPING YOUR COOL

    As the Covid-19 crisis subsides and economies can now look to reopen, companies large and small are planning their post-pandemic return to work structure. It is becoming more evident that fewer employees will be returning to the office place, and those that have been working from home will continue to do so, albeit on a part time basis.  Recent announcements from large UK based firms confirm that they will, where possible, be implementing a 3-2 plan for employees, requiring them to work from home a minimum of 2 days per week.

    WORKING FROM HOME IS HERE TO STAY…

    Many of us will feel uneasy about returning to the daily commute to the office, the thought of cramming into crowded trains or squeezing into packed lifts is not something we are looking forward to.

    Encouragingly, studies show that we tend to work from home in a highly efficient manner.  On a personal level for us, it is quieter, safer, and less distracting. A mixture of working from home and the office, will keep us happy and motivated, and offer a more balanced working life.

    Due to the pandemic, we have in effect all been subject to one of the largest experiments in home working and there are plenty of statistics that prove the benefits not only to employees, but also the positive effect it has on the efficiency, productivity and ultimately profitability for companies.

    So, if this new trend is set to stay, what can we do to make our home office a place where we can work comfortably and efficiently?

    In our previous article 10 tips working from home during coronavirus we explain in more detail what simple measures we can take to improve productivity when working from home. However, coming out of the pandemic, given that the home office is going to become the norm, we look at permanent solutions to make your home office environment a comfortable, productive, and healthy place to be.

    HOW TO CREATE THE PERFECT ENVIRONMENT FOR YOUR HOME OFFICE

    It is especially important to have a dedicated workspace, free from distraction, to maintain focus and concentration levels. For most people this will mean converting a spare room, a garage or quiet corner in a larger room to a bespoke office area. Choosing the perfect office chair or desk is relatively straight forward, but during the working day the ideal ambient air temperature is equally, if not more, important.

    Throughout the winter months it is easier to regulate the room temperature, however during the hot and humid summer months, working from home could become extremely uncomfortable. If the space where you are working has poor air quality, then you will not be in a good position to perform at your best.

    Leaving windows and doors open for long periods of time can present security issues, distractions from outside traffic noise, or an invasion of unwanted insects, however keeping windows shut, will cause temperatures and humidity to rise quickly, especially if you use heat producing electronic devices.

    Maintaining Domestic Air Conditioning at Your Home in UK

    The installation of domestic air conditioning in the UK has become a must have for the hot summer months.

    If you have recently installed an air conditioning unit, it is of utmost importance that you maintain your unit so that it can perform at its best.  Did you know that some parts of an AC unit including, filters, coils, and fins, require proper maintenance for them to function correctly. Neglecting any necessary maintenance can result in substantial repair bills later on, as well as a shorter lifespan of the unit.

    After your domestic air conditioning installation, you will need to perform regular maintenance checks.

    Here’s a guide to maintaining a split air conditioning system.

    Air Conditioner Filters

    Filters should be your top priority. Dirt and debris will slowly start to collect on your AC’s air filters. Not cleaning them regularly can cause that dust to escape into your room and cause health issues. This kind of leakage can degrade air quality and cause severe issues for someone with dust allergy or asthma. Moreover, clogged filters can reduce airflow and system efficiency, ultimately causing your system to malfunction, a costly situation that most people would not welcome.

    Air Conditioner Coils

    The evaporator and condenser coil can collect dirt from the filters over time, which is why it is so important to clean your filters at regular intervals to avoid this.  However,  despite best efforts, the coils will still collect a certain amount of dirt. This dirt causes a film around the evaporator coil to form, making it difficult for the coil to absorb heat and reducing the airflow. The outdoor condenser coil could also collect debris from the outside. You can easily find the condenser coil in your outdoor unit and check if it requires any maintenance.

    Coil Fins

    Aluminium fins over the evaporator and condenser coil can be bent easily. A tool called a “fin comb” is available to purchase. Your air conditioning technician can use this tool to make the coil fins go back to their original state.

    Clean and Clear Drains

    Once in a while, try passing a copper wire through the drain pipes of your system. If the drain is clogged, it will be challenging to reduce the humidity. High humidity levels on the inside can cause your walls and carpet to become discoloured.

    Sealed Rooms For Better Cooling

    For through the wall or window air conditioners, you should also inspect the seals around the unit.  Ensure that there are no gaps that can allow air in or out as this can cause moisture to collect, causing damage to the seals. Also any gaps can also allow unwanted insects to enter your property and also possible contaminants from the outside.

    Winter Preparations

    When the winter season is around the corner, cover your wall mounted indoor AC unit. Also, cover the outdoor unit with a plastic sheet or a cloth to prevent any dirt from getting in it.

    Know When You Need Help

    If you think that your unit requires an inspection by a professional, hire an A/C technician. The technician will help you with any problem in your air conditioning system.

    Tips for Wall-Mounted Air Conditioning Installation

    There are several important factors to be taken into account when considering a domestic air conditioning installation.  The exact location of your wall mounted air conditioning unit will need to be carefully planned, ensuring that it is installed at the correct height, in an unobstructed position and in a well ventilated space.  An ill-considered installation can result in premature wear and tear, and will often lead to higher running costs, increased maintenance and the unnecessary expense of mechanical failure.

    In this article, we expand further on the points raised above and give you some useful guidelines on how to choose the best place to install your AC unit when considering domestic air conditioning in the UK.

    Keep the Space Properly Ventilated

    To have an instant cooling effect in your house, the air conditioning vents must not be blocked by furniture or any other item. If the vents are blocked, you will not be able to receive the maximum output from your AC unit. For the best results, ensure that there no obstructions near your AC unit. The clearance distance varies from one manufacture to another, however, the general rule is to have 1 foot (or 12 inches) of free space around the unit.

    Install the Indoor Unit As High as Possible

    When installing your AC unit, make sure that you place it near the ceiling of your room. This rule is based on simple physics. Hot air rises, so the nearer the ground your unit is, the longer it will take to cool the room.  This will lead to increased power consumption, and higher electricity bills.  Placing an air conditioning unit higher will also ensure that there is less opportunity for objects to hinder the airflow, and at this height there is more room to place all the pipes and ducts.

    Place the Indoor Unit in a Shaded Area

    Continuous exposure to sunlight will increase your AC unit’s workload and can have a negative impact on its performance. The increased workload will eventually result in the premature wear and tear of your AC unit.

    If possible keep your curtains and blinds closed, as this can increase the air conditioner’s lifespan and reduce expenses. Install your indoor unit away from heat-generating items, such as bulbs, gaming consoles, and other electronic items, otherwise the AC unit will need to work harder to maintain the overall room temperature.

    The Correct Location for the Outdoor Unit

    Just like the indoor unit, the outdoor one also requires to be placed in a well-shaded area.  Sunlight, along with the heat that is generated from the condenser, can cause overheating issues.

    Moreover, the outdoor unit should be placed on a flat and rigid surface. The unit contains a condenser, a compressor, a fan motor, etc. everything to keep an AC functional. Without any proper support, the vibrations from a poorly installed outdoor unit can be excessive, which can then cause breakage of copper wires, coolant leakage or compressor/condenser damage.

    Conclusion

    If you are considering a domestic air conditioning installation, please ensure that you have researched and considered the factors mentioned above before the start of the installation process.

    However, for a seamless installation, we would recommend you choose a specialist air conditioning installer to guide you through the complicated process. They will help you choose an air conditioning unit that is specific to your requirements, and ensure that it is installed correctly.

    Why Air Conditioning In The UK Is Becoming A Necessity

    If you are reading this article you have probably arrived at the decision that you need to invest in some form of air conditioning in your home.  Summers in the UK are becoming increasingly hot every year due to global warming and environmental factors. This summer is no exception, we have experienced soaring temperatures and multiple heatwaves. This intense weather has skyrocketed the demand for air conditioners across the country. More people are now adding air conditioning systems at their homes and workplaces than ever before. If this is your first purchase, make sure to keep a few things in mind. Start by doing your own research on available brands. Then, make a list of models and their prices. Here are a few things that will help you get started:

    Where to Start?

    During the hot and humid summer months a portable fan may not be sufficient to keep your room cool.  You may wish to consider installing an air conditioner, a cost effective and efficient way to keep your room (or rooms) cool and free from humidity. Take time to research the different options such as portable AC’s, window AC’s and split units and consider the one that suits you best.

    What is the Best Long-Term Option?

    If you want a quality, durable product, it is advisable to consult with an air conditioning professional such as Evergreen Environmental. Our qualified team will help you select the right option tailored to your needs. We will assess your requirements, and after careful consideration will suggest the most suitable unit. We offer free air conditioning site surveys, advice, and quotations to all our clients.

    I am Installing an Air Conditioning Unit for the First Time – What to do?

    Possibly the most important factor when choosing your air conditioning is the sizing of your room and the new AC unit. If you pick an air conditioner that is too small for a room, you’ll not feel much difference in temperature, if any. If your air conditioner is too large for the room, you’ll waste a lot of energy as your system will be constantly turning on and off to try and regulate your temperature.

    When determining the correct unit for you we will ask for the exact dimensions of the room to determine which is the best option for you. Our air conditioning specialists will guide you through the whole process, so that you are fully confident. There are many considerations to take into account such as energy usage, the cost of purchase and installation fees and we will help you make informed choices taking into account your budget and individual requirements.
