How to Prepare Your Furnace for the Winter
Check These Components Before The Cold Weather Hits!

Summer has come to an end and the air is starting to get a little crisper outside. With the colder weather well on its way, this is the perfect time to fire up your furnace and make sure it’s working smoothly, safely, and efficiently. The last thing you want is a furnace that isn’t working right when you need it the most. We’ve put together a checklist of things to inspect and clean before the heating season begins – check it out below or watch our video!

Turn the Furnace on

  • It’s a good idea to fire up your furnace to make sure that it starts up quickly and there aren’t any noises coming from either the blower fan or the inducer motor.
  • Turn the heating setting on and turn the temperature up a few degrees higher than its current temperature.
  • Make sure the power source to the HVAC system is also turned on.
  • If you don’t hear the heat turn on in a few minutes, you may want to take off the thermostat cover and make sure the wire connections are intact (if comfortable).
  • If it is still not working, you will want to check the furnace fan, blower, inducer motor, burners, or the heat pump.

Tip: Consider using a programmable thermostat if you don’t already, this will help with energy savings.

The Air Filter

  • You will likely have an air filter behind a vent grill in the wall or ceiling, or a filter in the HVAC system itself.
  • Changing the air filter is extremely important as it keeps particles out of your HVAC system, ensuring it runs smoothly, and safely.
  • If your HVAC system includes a humidifier, change the humidifier filter too.

Tip: The air filter should be inspected and cleaned or replaced at least twice during the heating season, but this will depend on the specific instructions set by your manufacturer.

The Blower Motor

  • Check your owner’s manual to see if your motor is the kind that needs to be lubricated.
  • If it needs to be lubricated, turn off the power, clean the caps that cover the bearings, and remove the caps and lubricate the bearings.

Check the Air Vents

  • Check all the air vents in the home and make sure they aren’t being blocked

Do an Overall Clean

  • To help prolong the life of your unit, take a vacuum, and remove any debris that has made its way in and around the furnace.

Tip: Every few years you may want to consider having your duct work professionally cleaned

Cover the AC condenser (unless your HVAC is a heat pump)

  • Cover the condenser to protect it from the outer elements (leaves, debris, icicles).

Inspect the Chimney and Carbon Monoxide Detectors

  • Carbon monoxide is odorless and can be fatal
  • Every floor should have a working carbon monoxide detector and they should be inspected to ensure they are working properly.

By performing these quick checks and maintenance tasks, it should prepare your furnace for the upcoming heating season and ensure your HVAC system is running smoothly! For more tips and tricks for around the home, check out our YouTube channel!
