How Often Should You Change Your HVAC Air Filter? It Depends.
If you haven’t changed your home’s air filters lately, this 1-minute video will demonstrate just how much energy your HVAC unit is wasting. A clogged air filter operates with a lot less efficiency.
Air filters should be changed at least once per quarter. In certain circumstances, however, more frequent replacements are warranted.
- Homes with shedding pets
- Homes under construction
- Brand-new homes with dust in the air
- Homeowners with asthma or allergies
Also, when you replace your filters, don’t reach for the $0.99 cheap ones. Plainly, they don’t work. Instead, spend $15 to get a filter that works. Or, buy in bulk to save 15% from Amazon.com or a local hardware store.
