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.

• 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.
