• If the system is found to be low on refrigerant, a leak test is performed to find the source of the leak. Leaking refrigerant heats up a vehicle and damages the ozone layer.
• Refrigerant may be added, if necessary, to “top off” the system, although some states do not allow “topping off.”
• A technician may also check for evidence of refrigerant cross-contamination.
• A/C service should also include a check of the compressor’s drive belt and tension.
The Car Care Council also recommends that when having a vehicle’s HVAC system inspected, the cabin air filter be checked to make sure air is flowing properly into the car.
