If the summer heat drives you to distraction, the last thing you need is a malfunctioning air conditioning (A/C) system when you’re on the road. Checking your vehicle’s A/C annually will help you keep your cool when temperatures soar.
A typical A/C service consists of the following steps:
- A service 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.
