- Service technician visually inspects hoses, lines, seals and other components for leaks as well as inspect the drive belt for cracks or damage.
- Technician checks pressures to test operation, refrigerant charge and outlet temperatures.
- If the system is found to be low on refrigerant, a leak test is performed to find the source of the leak. Keep in mind that if your vehicle is leaking refrigerant, it is damaging 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, which is the mixing of refrigerants.
- 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.
“Making sure your A/C system is working properly will keep you cool and safe when you hit the road this summer,” said Rich White, executive director, Car Care Council.
