Winter is coming, which means it’s time to do your regular check on the gas furnaces in your home. Without regular maintenance, gas furnaces can fall into disrepair and break down unexpectedly.

However, maintaining gas furnaces is simple and can be done by performing a few checks before the winter season arrives. Here are a few simple steps that can help you keep your gas furnaces in great shape throughout the winter months.

  1. Before performing any maintenance on your furnace, turn off the system’s power. You should be able to find a switch plate near your furnace and the fuel shutoff valve near the oil tank.
  2. Remove the furnace door and inspect the burner flames. Turn up the flames by cranking up the thermostat and making sure that the flames are even and blue. Different colored flames, such as yellow flames, indicate dirty burners that need to be cleaned by a professional HVAC technician on our team at Acosta Heating and Cooling.
  3. Vacuum out the base and burners. Make sure you vacuum wherever you see dust, soot, or debris. Also remember to vacuum the lower compartment by lifting the blower door.
  4. Open the blower compartment and clean the blower blades with a vacuum and small brush. If you feel as if you can’t clean the blower yourself, leave this part for someone with more experience as you could accidentally throw off the balance of the counterweights or disturb the wiring.
  5. Change the furnace filter. This one tip alone can make a big impact on the indoor air quality in your home as well as the way your furnace functions. Change your filter every one to three months and pick a filter that is high on the MERV (minimum efficiency reporting value) scale to ensure that you are trapping allergens and dust that would otherwise be circulated throughout your home.
  6. Clean the pilot by using a can of condensed air or blowing through a straw. This will prevent the flame sensor from getting a false reading that the pilot isn’t lit.
