Regular maintenance is key to prolonging the life of your furnace, making sure that it works well for many years to come. Whether you choose to perform your furnace maintenance annually or seasonally, by yourself or with the help of an expert, it is important that you thoroughly service your equipment to keep it in top condition.

The experts at Evam have put together these tips on how to service a gas furnace at home so you can enjoy a trouble-free heating season this year! Remember, before performing any of these maintenance tips, always shut off your furnace for safety reasons.

1. Change the Air Filter

While this is an obvious gas furnace maintenance step, many home owners do not change their air filter often enough. Since dirt and debris in the filter can greatly reduce the efficiency of your furnace, be sure to change your filter regularly, especially during the heating season.

2. Get Vacuuming
   Open your furnace and vacuum around the blower motor to remove dust and debris. Next, vacuum around the exterior of your gas furnace. Finally, vacuum all of the air registers around your home to make sure they are clear as well. Any blockages can restrict airflow and cause your furnace to be less efficient.
3. Lubricate the Blower Motor
   A well-lubricated and clean blower motor works more efficiently and stays cool. While many gas furnaces feature permanently lubricated motors, others have oil ports above the bearings that need to be tended to on an annual basis. Add a few drops of non-detergent motor oil to each oil port. Always consult your furnace manual or a professional if you aren’t sure what type of oil to use.
4. Clean the Pilot Light, Flame Sensor & Igniter
   Use a drinking straw to blow dust off of the pilot light and igniter, and use an emery cloth to remove dust and carbonization from the flame sensor. Dirty pilot lights, igniters and flame sensors can cause issues with your furnace not turning on, or prevent it from heating cool air.
5. Inspect All Components
   Look at the heat exchanger, blower motor, fan belts, condensate line and more for signs of rust, cracks, holes and general degradation. If you notice any of these signs, be sure to call in an HVAC repair technician to handle these more difficult service tasks and repairs.
