How to Tell if Your Gas Furnace is Operating Properly

The condition of your gas furnace can have a large impact on your home’s energy cost and the health of your family. Your HVAC professional can give you the best analysis of your system’s performance, but you can still estimate its condition by inspecting it periodically. Make sure your furnace is:

  • Quiet. Some furnace noises are made during normal operation. However, pings, pops, rumbles and screeches aren’t sounds that you’d hear from a furnace that’s running like it should. Any of these sounds may indicate it’s time to have a professional service your system.
  • Odorless. After sitting for a long period without running, you may notice a burning dust or dirt smell during your furnace’s first few cycles. Any other odor can signal trouble, especially if you smell gas, burning rubber, or plastic. If you smell natural gas, leave your home immediately and walk away from your house before calling 911 or your gas provider. Turn your furnace off if you smell burning odors other than dust and call your HVAC provider for immediate service.
  • In good condition. Your gas furnace should show no signs of wear, rust, soot, or dirt deposits. When your furnace runs, the color of the flame inside the burner should be blue. If your gas burns yellow, this could be a sign it’s not getting enough oxygen and is creating carbon monoxide.
  • Clean. Checking your filter monthly and changing it when it’s dirty will extend the life of your system and keep energy bills lower.
  • Operating efficiently. Locate the specified temperature rise for your furnace on a plate inside the blower and test the temperature rise by placing an instant read thermometer in the register closest to the blower compartment. It should be close to what the manufacturer specified. If not, contact your HVAC professional.
