Changing the air filter in your HVAC system is simple and essential for maintaining air quality and system efficiency. Typically, you should change the filter every 1-3 months, depending on factors like the type of filter, number of people in your home, pets, and local air quality.

Signs that the filter needs changing include increased dust, reduced airflow, and longer system operation times.

To find the right filter size, check the dimensions printed on the side of the existing filter, usually in a format like 16x25x1 (width x height x depth). If not visible, measure the dimensions with a tape measure.

To change the filter, first, turn off the HVAC system. Locate the filter compartment, typically found in the return air duct or blower compartment. Open the compartment and remove the old filter, noting the direction of the arrows indicating airflow.

Confirm the size and insert the new filter with the arrows pointing toward the blower or air handler. Secure the compartment and turn the system back on.
