Question 1

What happens if you never change your air filter?

Accepted Answer

If you never change your air filter, the filter becomes clogged, which restricts airflow, causes your HVAC system to work harder, reduces indoor air quality, can lead to component failure, and increases energy bills.

Question 2

How often should I replace my HVAC air filter?

Accepted Answer

Most HVAC professionals recommend changing filters every 60–90 days in typical homes, more often if you have pets, allergy sufferers, or heavy HVAC use.

Question 3

Can a dirty air filter cause my HVAC to break?

Accepted Answer

Yes. A dirty filter restricts airflow, forcing key components like the blower motor and compressor to overwork and potentially fail prematurely.

Question 4

Does changing the air filter improve indoor air quality?

Accepted Answer

Yes. A clean filter effectively traps dust, pollen, mold spores, and other contaminants, reducing the number of pollutants circulating in your home’s air.
