Heating and Cooling System Maintenance
Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Preseason maintenance is important. It can help to avoid a system failure in severe weather when you need it most, and it can also keep your energy bill from getting out of control.
When Should I Do Furnace Maintenance?
We’ve all heard: an ounce of prevention is worth a pound of cure. You’ll find our Preventative Maintenance Checklist, which is a proven method to keep your system running and your home comfortable.
- For a system that both heats and cools: perform maintenance in the spring and fall
- For cooling system maintenance only: perform maintenance at least once a year, before the cooling season
- For furnace maintenance only: perform maintenance at least once a year, before the heating season.

- Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors and other accessories. All control box and electrical parts should be checked for wear or damage.
- Inspect compressor and associated tubing for damage
- Inspect and clean blower assembly (includes blower housing, blower wheel and motor)
- On some models, lubricate motor and inspect and replace fan belt if needed
- Check combustion blower housing for debris and clean as necessary
- Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed
- Inspect for gas leaks in gas furnaces
- Inspect burner assembly
- Inspect ignition system and safety controls
- Inspect heat exchanger or heating elements
- Inspect flue — check proper attachment, any dislocated sections and for signs of corrosion.
- Inspect control box, associated controls, wiring and connections
