furnace maintenanceYour family shouldn’t spend the winter wearing heavy sweaters under blankets at home, and your furnace filter plays a larger role in the overall temperature of your home than most homeowners realize.

Changing your furnace filter on a regular basis is an easy way to keep your furnace functioning the way it should, and your home as comfortable as it should be when you get home from work every day.

How your furnace works.

Your furnace works with three main pieces:

  • Return air.
  • Supply air.
  • The furnace filter.

The return air duct serves as the starting point. Air enters and is warmed through the heat exchanger with the assistance of a blower fan. The supply air vent sends the air on a trip around your house.  The furnace filter sits in a space between these two points, mediating and regulating the circulation of air. When you set your thermostat to your desired temperature, the furnace will continue to treat air until it has reached that temperature.

What a furnace filter does.

furnace air filterIndoor air contains more pollutants than outdoor air. Common pollutants and particles in the air include:

  • Dust.
  • Pet dander.
  • Mould.
  • Pollen.
  • Dirt.  

The furnace filter’s primary purpose is to clean the air moving through your furnace. It helps to minimize your exposure to these pollutants and as it catches air pollutants, it protects the blower fan from the pollutants and allows greater temperature regulation and air circulation. 

What happens with a blocked furnace filter?

Over time, the accumulation of pollutants in furnace a furnace filter affects its ability to capture pollutants. Irregular inspection and maintenance of a furnace filter compromises its functionality and overall purpose.

The blower fan has to work harder to reach the temperature you set on your thermostat and eventually the furnace motor will overheat and burn out.  You’ll end up spending more money on your energy bills and repairing your furnace with a dirty furnace filter.

Why would anybody let a furnace filter stay filthy?

We don’t know.

Changing your furnace filter on a regular basis keep your family warm and help maintain clean air, help your furnace last longer and keep your energy bill low. Take good care of the furnace air filter and your furnace will take good care of your family.
