Air Conditioning Servicing

A vehicles air con system requires regular gas re-charging to maintain optimum efficiency.

For best results the system should be serviced every two years. A system low on gas has to work much harder, putting extra strain and wear on the compressor, and ultimately costing you more in fuel to run.

When servicing a system it is imperative that all the old gas, contaminates and any moisture in the system is completely removed before re-gassing, any moisture left in the system can form ice crystals which can seriously damage the compressor.

When re-gassing the correct amount and grade of lubricating oil must be added to ensure satisfactory operation and life expectancy of the compressor is ensured. Just think of an old motor scooter or mower, you had to add two stroke oil to the petrol to lubricate the piston. Well effectively it’s the same in an air conditioning compressor, the pistons need lubrication, so beware of cheap gas top ups, they could damage your compressor.

We offer the latest in machine technology, top of the range fully computerised equipment, used by fully qualified vehicle technicians.
