Winter is coming and your furnace is likely to face heavy loads during the cold weather. It is essential to get your furnace checked before the season starts because you do not want to be stuck in a cold house with a non-functioning furnace. But worry not! Our furnace maintenance checklist will tell you what you need to do to ensure that your furnace runs smoothly throughout the winter. Here are our top tips for furnace maintenance that you need to follow:

Turn on Your Thermostat

It’s time to switch your thermostat from heating to cooling mode. This is also the ideal time to test the thermostat’s fan speeds, temperature and adjust its schedule. To do this, you can set the temperature slightly higher than the room temperature and listen if the heat kicks on sooner than later.

Replace the Air Filters

The air filters in your furnace should be changed every one to two months. If you haven’t ticked this off your furnace maintenance checklist yet, now’s the ideal time to replace them. This will also lower your heating bills in the long run.

Clean the Burners and Flame Sensors

After a period of time, the burner in your furnace develops a carbon build-up. Thus, it is essential to have it cleaned before winter arrives. Switch off your furnace and vacuum out the carbon debris around the burner. Clean its orifices thoroughly and inspect for any cracks. Do not ignore the flame sensor, as it can turn off your furnace if kept dirty. Disconnect its wire and scrub off any soot build-up you find on it.

Inspect the Heat Exchanger

One of the most important tips for furnace maintenance is to have your carbon monoxide detector checked every month for any signs of leaks or carbon build-up. Before winter arrives, you also need to check the heat exchanger for any cracks. To do this, turn your furnace to fan-only mode, light a match, and place it in front of the heat exchanger cells. If the match goes out or blows in the wind, your heat exchanger likely has cracks.

Lubricate the Fans

Inspect the blower and inducer fans of your furnace. If the fan wheels do not spin smoothly, you need to oil the motor or the motor shafts. Also, check if the fan belts and pulleys are functioning correctly. Otherwise, you will have to replace them immediately.

Clean or Replace the Humidifier

Cleaning out the humidifier every month should be on your furnace maintenance checklist. Before winter arrives, adjust the damper and open it up to supply enough humidity during the dry climate.

Check the Electricals

Inspect the overall functioning of your furnace by looking for any loose wires or rusted terminals. Test the switches and all other electric controls to make sure they are working properly. Dust off the debris collected in the electrical area to prevent any kinds of short circuits.

Inspect the Ductwork

One of the final tasks on your furnace maintenance checklist is to inspect and clean the heating ducts. Check for air leaks, mold or mildew growth and use a plastic utility brush with some light detergent to get rid of the latter.
