What is Air Conditioning (AC)?

A brief introduction

Air conditioners blow cool air into your home by pulling the heat out of that air. The air is cooled by blowing it over a set of cold pipes called an evaporator coil. This works just like the cooling that happens when water evaporates from your skin. The evaporator coil is filled with a special liquid called a refrigerant, which changes from a liquid to a gas as it absorbs heat from the air.

The refrigerant is pumped outside the house to another coil where it gives up its heat and changes back into a liquid. This outside coil is called the condenser because the refrigerant is condensing from a gas back to a fluid just like moisture on a cold window. A pump, called a compressor, is used to move the refrigerant between the two coils and to change the pressure of the refrigerant so that the entire refrigerant evaporates or condenses in the appropriate coils.

The energy to do all of this is used by the motor that runs the compressor. The entire system will normally give about three times the cooling energy that the compressor uses. This odd fact happens because the changing of refrigerant from a liquid to a gas and back again lets the system move much more energy than the compressor uses.

Benefits of Air Conditioning

Cooling and heating both from the same unit
  • Most systems are capable of heating and cooling
  • There are a range of options and colours suitable for your home design
  • Relaxed and cooler night sleep for those hot and humid months
  • Easy to retrofit
  • Opening windows is a thing of the past as the air temperature in your room is so much cooler – resulting in a good night’s sleep

Air Conditioning Unit Options

A simple guide to the basic systems

Our recommendation would be to offer our customers Mitsubishi Electric air conditioning systems. A name synonymous with excellence. The bespoke maintenance package that we offer alongside the Mitsubishi equipment encompasses up to a 7 year fully comprehensive warranty on systems we install.

Domestic-Air-conditoning1

Wall Mounted Units

The wall mounted units are our most popular choice in the domestic market and are available in a range colours and capacity sizes.

Domestic-Air-conditoning2

Floor Mounted Units

Floor mounted units provide the best distribution of cool air and are ideally suited to being installed on an external wall. Floor mounted units also have the advantage of being encased to suit the aesthetics of your home.

Domestic-Air-conditoning3

Ceiling Mounted Units

Ceiling mounted units are more suited to the commercial market but they are also a viable option for those clients who have suitably sized roof voids to avoid the units being hung on useable wall space.

Air Conditioning Servicing

A cost effective way to ensure smooth, reliable and energy efficient operation
AES-Air-Conditioning-Header-2

Pre-Planned Maintenance

As with most electronic equipment it is recommended servicing is carried out regularly in order to ensure the system maintains is its optimal running efficiency in terms of reliability and operation.

In a productive office, it is understandable that the servicing of your air conditioning system does not always take priority. We all have busy working agendas. We recommend however, that taking the decision to act sooner can save you both hundreds of pounds in downtime and call out fees.

Our bespoke pre-planned preventative maintenance visits which are available on a yearly basis would substantially help reduce the chance of a breakdown occurring and maintain your system manufacturer’s warranty*.

You wouldn’t run your car without a service or an oil change and nor should you with your air conditioning.

*Assuming your system is within the manufacturer’s warranty period.

7 Year Comprehensive Insurance

Abel Environmental is proud to be affiliated with Mitsubishi Electric as a Business Solution Partner. This qualification status enables us to offer up to a 7 year fully comprehensive parts and labour warranty on Mitsubishi Electric air conditioning products we install and subsequently maintain.

Common Air Conditioning Problems

The main symptons

Many of the day-to-day air conditioning problems we encounter are caused by a lack of regular maintenance. We have listed below what we believe to be some of the main symptoms.

If you experience any of these issues please do not hesitate in contacting us to arrange an inspection, repair or service.

One of the most common breakdown calls we receive are related to a system leaking water. There are two possibilities for a unit leaking one of which is the lack of regular servicing or condensate pump failure. This kind of breakdown is easily repaired and is achievable within the first hour on site. Please call our team to arrange an engineer should you be experiencing the above.

If you feel that your air conditioning system is not performing at is optimal level of efficiency this may simply be that the unit has not been regularly maintained or serviced. The unit(s) could also be extremely dirty causing lack of performance. Having the system deep cleaned is often enough to resolve this problem.

However, it could also imply you have more serious issues – such as a refrigerant leak. A refrigerant leak requires a more in-depth investigation in order to resolve. Please call our team to arrange an engineer should you be experiencing any of the above.

If you experience your air conditioning freezing up and possibly dripping water onto the floor, you will require an engineer to attend site. We can check if the unit requires a deep clean, or if the refrigerant system is leaking and report our findings. If the unit is dirty, then it will be unable to ‘operate’ correctly, which then means the chilled air cannot escape into the room so the unit consequently freezes. The same effect happens if the system has a refrigerant leak. The unit will eventually fail and may result in a replacement unit being required.

Please call our team to arrange an engineer should you be experiencing any of the above.

Air conditioning units produce condensate (water), and this runs inside the units and is eventually removed from the system. This condensate mixed with ever-changing temperatures can create bacteria on the coils. Having the unit serviced regularly with the correct chemicals not only removes these smells but makes the system more efficient.

When it feels like the flow of air from the unit is not as powerful as before it might need a simple adjustment of the fan speed on the controller, or it could be a faulty fan motor especially if it sounds noisy. If the filters on the indoor unit are dirty, or grime has attached itself to the fan blades, it will require either a general clean or possibly a deep clean depending on the severity of the problem. Our air conditioning engineers can repair units or service them typically the same day we are called.

For a system to run at optimum performance, it needs to be able to breathe freely. If the air conditioner is blocked with muck and grime, then it has to work a lot harder to achieve the same amount of cooling or heating. The more blocked the air con unit is, the more electricity it will draw. Having the unit serviced regularly, therefore, lowers energy consumption, lowers repair and maintains manufacturer’s warranty.

General Air Conditioning Maintenance Checklist

We have highlighted below a short list of the some of the items which require checking during a normal air conditioning service visit.

Indoor Units

  • Clean filters
  • Clean evaporator coil
  • Check drip tray for dirt and debris
  • Clean and test condensate pump (where fitted)
  • Check all air on and air off temperatures in both cooling and heating
  • Check controls operation

Outdoor Units

  • Inspect and Clean Heat Exchanger
  • Check Visible signs for refrigerant leaks
  • Check pipework and lagging integrity
  • Check drip tray for dirt and debris
  • Check all air on and air off temperatures in both cooling and heating
  • Check electrical connections and tighten as necessary
