Upon completing the AC maintenance service call, I performed a comprehensive 26-point inspection. The condenser coil was thoroughly brushed and rinsed to remove built-up dirt and cottonwood. Refrigerant levels tested low at 68 psig, so I evacuated the system and recharged with 3.2 lbs of R-410A refrigerant per manufacturer specifications. TheContractorBlue pleated filter was replaced, and the evaporator coil was foamed to restore heat transfer efficiency. All electrical terminations were tightened, and voltage was verified within tolerances.
