You are welcome to watch as we service your aircon and we will explain each part of the re-gas service. The aircon service takes around 20 minutes. (Over 1 hour for automatic Ac Machine service)

Why suffer on a hot sticky summers day; when from only £49 you can be driving in a cold car, feeling cool and refreshed.

Using the latest air conditioning service equipment to make sure your car is re-gassed correctly to the manufacturer's air conditioning specifications.

We do not just top up your car with refrigerant, we always remove your old refrigerant. We vacuum to -29 hg the entire air conditioning system to remove any excess moisture; then test for leaks under vacuum. 



It is important to remove any moisture from your air-con system. This is done with a vacuum pump, this creates a vacuum of -29 hg; this will cause any trapped moisture to boil off at 10 degrees. This will then be removed from your car's air-con system. If the vacuum oil is not changed regularly; the vacuum pump will not be able to reach the desired vacuum pressure so the water will not be able to boil off; which will then be trapped in your system. This will cause ice up and cause blockages, also cause acid to build up and damage your car's air conditioning components. Some garages only change the oil annually, so they will not be able to get a proper vacuum. The importance of a regular oil change is very important to make sure your car is serviced correctly.

Do you have a musty smell when using your air conditioning? 


It is important to have your Evaporator cleaned regularly to stop the build-up of mould and fungi. The evaporator is situated inside the car under the dashboard. When you use your air conditioning water condenses on the evaporator, which can lead to mould and fungi forming. Regular cleaning when you have your service, using our anti-bacterial refresh, will help to keep your evaporator clean and healthy.
