Inspect unit for proper refrigerant level and adjust if necessary Clean dirt, leaves and debris from inside cabinet. Inspect base pan for restricted drain openings. Remove obstructions as necessary. Inspect coil and cabinet clean as needed. Inspect fan motor and fan blades for wear and damage on older models lubricate as needed. Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories.

Best Window Air Conditioning Units. Maintenance During Operation.

Monitor system starting characteristics and capabilities. Listen for abnormal noise. Search for source of unusual odors. Monitor air conditioning and heat pump systems for correct refrigerant charge. Measure outdoor dry bulb temperature. Measure indoor dry and wet bulb temperature. Measure high and low side system pressures. Monitor gas furnace for correct line and manifold gas pressure make adjustments as needed. Measure temperature rise and adjust airflow as needed. Check vent system for proper operation. Monitor system for correct line and load volts/amps. Monitor system operation per manufacturer's specifications. Provide system operation report and recommend repairs or replacement as necessary.
