PPM Air Conditioning Maintenance Checklist

This planned preventive maintenance checklist is designed for servicing air conditioning units in facilities. It captures site and asset details, serial numbers, gas type, and refrigerant charge. Tasks include checking and cleaning filters, inspecting fan motors and bearings, assessing compressor noise and vibration, confirming refrigeration charge, checking for gas or oil leaks, and ensuring guards and inspection plates are secure. It guides cleaning of evaporators, coils, drains, drip trays, and pumps, verifies condensate drains are clear, and inspects electrical conduits and control panels for damage or overheating. The checklist records temperature set points, ambient and internal temperatures, humidity, and tests maximum cooling and heating. It includes before and after condition records and prompts reporting of defects and recommendations, with an engineer sign off.
