HVAC filters help keep your home’s air clean and free of dust, pollen, and other allergens. A dirty filter can restrict airflow and make your HVAC system work harder, which can lead to higher energy bills and premature system failure. That’s why it’s important to change your HVAC filter regularly.
How often you should change your HVAC filter depends on a number of factors, including the type of filter you have, the climate you live in, and how often you use your HVAC system. However, a good rule of thumb is to change your filter every 1-3 months. If you have pets or allergies, you may need to change your filter more often.
