Air Conditioning (A/C) System Performance Test: Notes
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The following test measures the A/C system operating efficiency by comparing:
- The ambient air temperature
- The ambient air humidity
- The pressure at the high-pressure side of the refrigeration system
- The pressure at the low-pressure side of the refrigeration system
- The temperature of the air being discharged into the passenger compartment
