Car Air Conditioning Diagnostics, Servicing and repairs

We are able to support our customers in the maintenance and repair of their car air conditioning, with fully trained staff & all the equipment needed to diagnose, service & repair this area of your vehicle. Our machine is top of the range ensuring accurate & efficient service, enabling us to service A/C systems on all vehicles from cars to motor homes, tractors to combines & buses to coaches.

Many people do not realize that their air conditioning is in need of a service, the difference is often very noticeable this service is not time consuming and can be done whilst you wait, shop or work - usually within the hour.

Air conditioning systems for vehicles are equipped with a dryer. This component has two functions. It has a drying agent to eliminate humidity from the refrigerant & also acts as a filter.

The dryer should be replaced every two years or whenever the system has been opened for repairs.

Also included in our A/C system service is an Air Conditioner Treatment which eliminates colonies of airborne bacteria caused by the build-up of mould and fungi on the evaporator in the deepest recesses of a vehicle's air conditioning system.

Basic principal



    • The System

      The Air Conditioning system is a closed system, consisting of two sections. The section that produces the cooling effect (Low pressure) runs from the expansion valve (3) as a liquid, through the evaporator (4) then back through the expansion valve (3) as a vapour.

    • The Compressor & Condenser

      The vapour from the expansion valve (3) travels to the compressor (2) compressing the vapour condenses it into a heated liquid (High pressure). The liquid then moves to the condenser (1) where it is cooled.

    • The Drier

      The function of the drier (5) is to remove any air bubbles or impurities from the refrigerant. It protects the whole system for damage caused by contamination.

    • The Evaporator & Expansion valve

      The evaporator (4) is basically the same as the condenser: A large surface works as a heat exchanger similar to a radiator. The expansion valve (3) relieves the liquid refrigerant into the evaporator. Due to the expansion the refrigerant changes from liquid back to gaseous. The process of evaporation demands a lot of heat, which is absorbed from the car's interior. If the refrigerant passed the evaporator it flows back to the compressor. This is called the low-pressured side.
