The heating season has finally arrived in the south. It’s time for a comprehensive furnace inspection and tune-up by a qualified HVAC professional.

Below is the Furnace Cleaning Checklist of maintenance tasks your HVAC professional should perform.
Furnace Cleaning & Maintenance
- Observe operation of unit, paying close attention to operation of fans. Loud fan operation can indicate premature bearing failure.
- Clean flame sensor & flame igniter to remove carbon build up.
- Inspect & clear all hoses to remove any blockages.
- Check fan blades for dirt & buildup causing excessive unit vibration & noise. Clean if needed.
- Inspect blower door to ensure there is a good seal, preventing surrounding non-temperature controlled air from being drawn inside unit.
- Check safety operation of blower door safety switch.
- Check duct connections at unit for air loss into surrounding environment.
- Test operation of the unit’s negative pressure safety switch.
- Check return filter to ensure adequate airflow through return duct.
- Clean burner rail assemble to remove carbon buildup, which can cause flame distribution to the heat exchanger.
- Check all electrical entry points into the unit to ensure wire connectors exist & are secure.
- Check wires & connections. Replace any wiring showing signs of heat damage or with cracked insulation.
- Check evaporator coil for blockage, which could prevent adequate airflow.
- Check blower capacitor to ensure proper speed of fan motor.
- Inspect all pipe fitting connections along gas line supply to ensure no gas leaks exist.
- Check heat exchanger for cracks & corrosion.
- Check combustion safety switch for proper operation.
