Furnace & Heat Pump Maintenance & Inspection
Furnace and Heat Pump Maintenance & Inspection
Just by inspecting and servicing these parts of your furnace and heat pump, you can improve the efficiency and extend the life of your system:
 

Air filters
Dirty air filters cause a reduction in airflow which overheats motors, wiring and heating elements. This can damage heat pumps which rely on a certain amount of airflow across the indoor refrigerant coil.
 
Indoor refrigerant coil
Wash coil with pump sprayer and special coil cleaner if needed. This has the same effect on a system as a dirty air filter. If customer is using an inefficient air filter or no filter at all, the coil will probably need to be cleaned. Blow out condensate drain line. If line plugs, water may overflow onto motor and electrical components causing costly repairs or damage to the home.
 
Motors
Oil motors on older systems. Newer motors have sealed bearings which don't require oiling.
 
Elements, wiring, switches & capacitors
The motors in a furnace and the compressors in heat pumps have capacitors which give starting and running torque. A weak capacitor causes overheating and premature system failure.
 
Refrigerant charge
A heat pump low on refrigerant will ... more
