We use top quality machines from Viper, Bosch, Ecotechnics and Texa as well as stand alone AC diagnostic machines for checking compressors and valves.  We are also proud to announce the introduction of our new R1234YF gas air conditioning machine.

We are undoubtedly the undisputed market leader in vehicle air conditioning technologies in Northern Ireland.

 

How Air Conditioning Works.

Your AC system consists of these main parts:

  1. Compressor
  2. Pipes & Hoses
  3. Condensor
  4. Expansion valve or orifice tube
  5. Evaparator
  6. Receiver Drier or accumulator

There are two basic types of AC system.  One that uses an orifice tube and accumulator and one that uses an expansion valve and drier.  The latter being most popular.

A car AC system is split into two section, high pressure and low pressure.

It is a closed loop system that uses the compressor to change from a low pressure gas to a high pressure gas which is then cooled again by the condenser into a high pressure liquid.  This liquid is then pushed through the drier which acts like a filter taking any moisture out of the system.  It is then transformed through the expansion valve to the vehicles evaporation which is in the interior of the car.  This is where the magic happens.  The liquid refrigerant that is supplied to the evaporator by the expansion valve expands to a vapour as it absorbs heat from the air and it is this process that removes the heat and moisture from the cabin.

So the main function of a car AC system is not cool air in the summer but to create a pleasant and odour free atmosphere in your vehicle at all times.
