The air filter in your HVAC system plays a significant role. It’s one of the first lines of defence against pollutants and allergens in your home. Find answers to the five most common questions we hear from our customers about their air filters:
1. How does an air filter work?
As air passes through your HVAC system, the air filter traps airborne contaminants before recirculating the air back into your home. As a result, the system components remain cleaner and your HVAC system can heat and cool your home more efficiently.
2. Why should I replace my air filter?
A dirty and clogged air filter restricts airflow, making your HVAC work harder than it should be. Regularly changing your air filter can help extend the lifespan of your HVAC system, improve your home comfort and indoor air quality, ensure optimal performance and reduce your energy bill.
3. How often should I change my air filter?
We recommend replacing your HVAC air filters every 30-60 days depending on your living situation. Change your air filter more regularly if:
- You have pets inside your home
- A member of the household has allergies or asthma
- You have a large home
- You have an older home
- You run the AC continuously
4. How do I find my furnace air filter?
Your air filter is most likely located within your furnace, which can often found in the basement, garage, or furnace closet. If you have an older model, the filter may be inside the blower cabinet or in an in-wall return air grill. Depending on the unit, the filter may be horizontal or vertical.
5. How do I clean or replace my air filter?
Turn off power to the HVAC system. Once you have located the air filter, take note of the airflow direction. Remove the filter and inspect the amount of dust, dirt and debris. Gently clean the air filter with a vacuum cleaner nozzle attachment if you can see the light through the filter. Otherwise, replace it with a new air filter. Slide the clean or replacement filter into the housing, ensuring that the airflow arrows face the correct direction. Secure the panel cover and restore power to the unit.
