When it's hot outside, one of the last places you want to be is sitting in traffic without a properly functioning air conditioning (A/C) system. To help avoid this uncomfortable situation, the Car Care Council recommends having your A/C system checked annually to make sure it's functioning at its peak performance level when the temperatures are soaring. A vehicle's heating, ventilating and air conditioning system (HVAC) keeps the interior cabin comfortable in any season by providing the right temperature and humidity level. Typical A/C service consists of the following steps:
- 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.
- A technician may also check for evidence of refrigerant cross-contamination, which is the mixing of refrigerants.
- An A/C service should also include a check of the compressor's drive belt and tension.
