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.


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.


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.


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

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.
