What Is Included in a Typical HVAC Maintenance Checklist?

A typical HVAC maintenance checklist includes cleaning, safety checks, calibration, lubrication, airflow verification, and a full performance test. Most tune-ups begin by checking airflow and filters because restricted airflow strains parts and raises energy use. For cooling, technicians focus on refrigerant, coils, drains, and electrical safety; for heating, they inspect components, clean dust, and confirm safe controls and ignition. Our teams that service homes around the Buffalo–Lancaster area apply these steps during seasonal visits.

• Replace or clean air filters and verify airflow through ducts and vents.
• Test thermostat accuracy and recalibrate; inspect control board and electrical connections.
• For AC: check refrigerant levels/pressures, clean condenser coils, and clear the condensate drain.
• For heating: examine furnace components, remove dust/debris, and confirm safe operation.

If you notice short cycling, unusual noises, or water around the unit, schedule a professional inspection instead of continuing to run the system.
