While we recommend a professional heating system checkup and furnace cleaning once a year, here are several things you can do yourself to keep your furnace operating at peak efficiency.

Change or clean filters at least once every three months and keep the fan compartment door tightly closed.

If you are heating with propane or natural gas, leave your pilot light on year-round. This prevents condensation from building up in your heat exchanger.

Keep vents and air returns clear of obstructions such as furniture, lint, dust or pet hair.

Check the chimney and appliance vent system at least once a year to ensure that all connections are secure.

Visually inspect your oil tank for leaks.
