Your furnace is an important component of your home and is needed to keep the indoor temperature comfortable during the frigid winter months. There is nothing quite like dealing with a lifeless heater in the depths of winter. Fortunately, there are some simple tasks you can complete in preparation for the cold, so you can guarantee that your furnace is working dependably and safely throughout the winter season.

Regularly Swap the Filter

The filter is responsible for collecting dust, debris and pollens to make the air in your home cleaner. Be sure to regularly change your filter, and it sure wouldn’t hurt to buy a couple of extra during the summer season.

Remove Obstructions

Keep the air flowing freely throughout your home by taking a minute to remove vent obstructions. Make sure furniture and clutter are out of the way of vents. You may also benefit from taking a vacuum and simply cleaning out the ducts for optimal air flow.

Clean Up Around the Flume

The air flume on the exterior of your home can sometimes become blocked by debris, or you could discover a surprise bird’s nest. Remove any blockage to maintain the safety of your family and the function of your furnace. Other preparations you can make include inspecting the blower belt and programming the thermostat and ensuring all air vents are open.
