Air Conditioning Re-Gas - R134A

Your Air-Conditioning doesn’t just provide in-car comfort during the hot summer months; it can also be used in winter to demist your windscreen. Air-con systems create dry warm air rather than the normal humid air from outside which can clear your windscreen much more quickly than your regular blowers.If the Air Conditioning system isn’t working properly moist air won’t be able to demist the windscreen, affecting visibility.

Around 10% of air-conditioning gas will be lost from the air-con system every year, that's why most car manufacturers recommend that the air-con system is recharged with new gas every 2 years

Air-Con Service (R134A) £69.00.
