How Often Should You Change Your Furnace Filters to Optimize Efficiency?

Many people take their home furnaces for granted. But these out-of-sight, out-of-mind appliances make modern living comfortable. Your furnace warms your home during the winter and cools it during the summer. Moreover, furnaces enable clean air to circulate throughout your home, reducing indoor air pollution. For this reason, furnace installation in Calgary is a necessity. Also, regardless of your furnace’s age, it needs upkeep; if you notice dust bunnies and pet dander accumulating, your furnace filter might need replacing.

Furnace filters catch dust and airborne particulates before debris gets into the system, potentially damaging sensitive internal equipment. Most of the air in your home funnels through your HVAC system; as such, your furnace filter is the first defence against debris and air pollutants.

How to Know When to Change Your Furnace Filter

There are a few guidelines for how often you should swap your furnace filters. However, reviewing your owner’s manual for the manufacturer’s recommendations is always best. Usually, swapping a fibreglass furnace filter every one to two months and a paper furnace filter every 6 months to a year is a good rule of thumb.

Electrostatic furnace filters are the longest-lasting. They can last for years if cleaned at least once every four weeks. Additionally, you should clean your furnace filters regularly if any of the scenarios below are true:

  • You own one or more pets
  • Dust buildup in your home is accumulating
  • You are (or live with) a smoker
  • You notice dirt, dust, or debris accumulating on your current filter

What’s the Process for Changing a Furnace Filter?

You can change your furnace filter reasonably quickly. However, again, you should review your manual for the correct procedure. But generally, changing a furnace filter is as follows:

  1. Shut down your furnace
  2. Find the service panel and remove it
  3. Take out the current filter (near the blower fan)
  4. Place the new filter inside
  5. Turn on your furnace once more
