Climate Control System

NOTE: All air conditioning (A/C) related tests should be run in an ambient temperature of at least 10 degree C (50 degree F).

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. Listen for any unusual noises during climate control system operation.
4. Inspect the refrigerant system with an ultraviolet (UV) lamp for traces of UV sensitive leak trace dye.
