Change Filters
Replace the old filters with new ones.
Step 2Inspect Equipment Panel
Open the equipment panel and inspect. Verify crankcase heaters are warm to the touch on the exterior.
Step 3Inspect and Clean Electrical Connections
Inspect for loose/dirty connections, scorching, or damage. Use a blower to clean. Tighten all terminal screws.
Step 4Check Blower Assembly
Roll belt to inspect wear; note if replacement is needed next PM. Spin motor and blower; listen/feel for bearing noise or play. Check pulley condition/alignment. Record supply fan motor amp draw (compare to nameplate). Close the panel.
Step 5Verify Fan Motor Shafts
Check condenser/evaporator fan motor shafts for slop, abnormal noise, or oil residue.
Step 6Evaluate Cooling Performance
Run AC and evaluate cooling. Record compressor(s) and condenser fan amp draw (must be under nameplate); measure supply and return air temperatures to get delta-T; confirm suction line gets cold and condenser discharges heat.
Step 7Verify Temperatures
Record condenser discharge air temperature (warmer than ambient) and supply air temperature at the duct (significantly cooler than return; note outdoor air influence if applicable).
Step 8Inspect Coils
Inspect the coils. Decide if coil cleaning should be scheduled for the next PM; identify a safe water source if cleaning will be needed.
