During the fall and winter season, a malfunctioning furnace can be a very serious problem. Just because your furnace is functioning, doesn’t mean that it is working correctly, efficiently or safely. Furnace manufacturers recommend annual maintenance to ensure safe, efficient operation and decrease the likelihood of a costly breakdown. Regular service will also reduce your energy bill and help extend the lifespan of your unit.

How to Maintain a Furnace

Both gas and oil furnaces use a fan and ducts to distribute and transport heated air throughout the home. When the furnace is operating correctly and efficiently, the fan distributes heated air while simultaneously pulling cooler air back into the furnace through a system of return ducts. That cool air is reheated and then distributed as well.

Gas Furnace Maintenance

The components to your gas furnace that require regular maintenance and cleaning include:

  • Gas burners — Clean burners reduce the likelihood of a breakdown.
  • Blower compartment — Vacuum out debris to ensure proper air flow.
  • Exhaust vent piping — Be sure pipes meet manufacturer’s specifications and local safety codes.
  • Condensate traps and air tubes — Unclog tubes to prevent breakdowns.
  • Condensate pump and drainage system — Clear the drainage system to prevent harmful and costly leaks.
  • Electrical connections — Replace or repair any run down or unsecure connections.
  • Gas piping — Be sure pipes must meet local safety codes.

Oil Furnace Maintenance

The components to your gas furnace that require regular maintenance and cleaning include:

  • Oil line nozzle – Change the oil line nozzle to prevent system breakdowns.
  • Oil filter – Change filters to prevent sludge build up and promote oil flow.
  • Oil pump screen – Check, clean and replace as necessary.
  • Flame retention head – Inspect component for cracking or warping, which can inhibit combustion and waste fuel.
  • Burner blower wheel – Clean wheel to ensure it is circulating enough air.
  • Oil burner – Clean the burners to prevent system breakdowns and maintain energy efficiency.
  • Combustion chamber – Check chamber for dangerous cracks. If any are found, repair or replace the cracked component.
  • Oil lines – Check lines for rust, corrosion and leakage.
  • Electrical connections – Replace or repair any run down or unsecure connections.

Maintaining the following will help your oil or gas furnace run more efficiently and safely:

  • Air filters – Clean or replace several times a year to promote proper air flow.
  • Heat exchanger – Inspect the centralized compartment for rust and corrosion.
  • Thermostat – Monitor and properly set your thermostat to use energy as efficiently as possible.
