How to Change Your Furnace Filter
Cool weather is on the way, which means heating systems are being turned on. Did you know, if you have a furnace in your unit, you are responsible for replacing the filter at least annually preferably every three months? This isn’t just important for the life of your furnace - changing your furnace filter can help to save money on your heating bill. Experts say replacing a dirty furnace filter with a clean one can reduce energy consumption by as much as 15 per cent! This is because when a filter gets clogged up, it creates resistance to airflow in your system, which means your furnace has to work even harder to heat your home.
Filters should be checked monthly during the heating season and need to be changed when they are dirty. Calgary Housing Company (CHC) recommends you change the filter in October, before the heating season begins. The following tips will help you out.
- Instructions for changing your furnace filter are posted on your furnace, and included below.
- To check if your furnace filter is dirty, remove it and hold it up to the light. If you can’t see any light coming through the filter, then it needs to be replaced.
- Before heading to the store, take note of the size of filter that is required or bring an old filter with you.
- Furnace cleaning, which you are also responsible for, should be done every two years by a qualified cleaning company.
- The cost of furnace filters and furnace cleaning are your responsibility.

- Turn off the Furnace: Most furnaces have a power switch located next to the unit. Be sure to turn this switch to the off position before proceeding. If a switch is not visible, turn off the power at your fuse box to prevent injury.
- Locate and Remove the Filter: Furnace filters are normally found underneath the furnace, behind a slotted ventilation cover. Some covers simply pop out, while others are held in place with a few screws. Remove the cover carefully and set it aside.
- Check the Filter: Inspect the filter’s condition by trying to see through it. If light can pass well through it, it does not need to be replaced. If light cannot be seen through it, the filter needs to be replaced. The old filter will contain dust and other debris, so have a trash bag handy and disturb the old filter as little as possible.
- Buy a New Filter: Take the old filter with you to the hardware store to make sure that you buy a new one which has the same dimensions.
- Clean the Furnace Blower: The filter is right next to the blower, since it serves the function of regulating the air as it goes out of the furnace blower. Prior to installing the new filter it is suggested that you clean the filter area as well as around the blower area.
- Install The New Filter: Insert the new product into the space provided, ensuring that the directional arrows, if any, are pointing in the correct direction. Finally, pop or screw the cover back in place for improved air quality, system protection and reduced electric bills.
