Clogged air filters are the primary source of HVAC system failure, which is why it’s vital to regularly replace the air filters in a home. With clogged air filters, a household’s bills are apt to go up, the air quality for the home’s residences will be diminished, and mold can grow in the infrastructure of the home. Mold and bacteria can lead to illness or infection for the people who live in the house. There are many reasons (relating to financial, health, quality of life, and longevity of the residents) to replace filters often, ideally every month or two.
- With a dirty air filter, the blower fan has to work harder, resulting in increased energy bills.
- The material that clogs the air filter may become damp, inviting the growth of mold and bacteria.
- Air filters are inexpensive and you can change them yourself, preferably once every one or two months.
“This means that if you don’t change your air filter regularly, air can’t pass through as readily.”
