One of the most critical tasks for maintaining your HVAC system is regularly replacing the filter. It only takes a few minutes, but it keeps your system running efficiently, preserves the indoor air quality, and prevents the need for unexpected HVAC repair. Here’s how to handle the replacement on your own. 

What Is an HVAC Air Filter? 

An HVAC air filter is designed to remove dirt, dust, pet hair, dander, and other contaminants from the air as it flows through your HVAC system. This keeps the unit free of debris that can affect the motor and its functioning, and it helps ensure the air in your home is clean and fresh. The filter is located between the ducts that bring air into the furnace and the furnace itself. It’s usually accessible via a well-marked panel.

Why Do Filters Need Replacement?

When an HVAC air filter does its job, dirt and debris build up on the screen instead of traveling into the furnace and your home. However, as this dust builds up, it can block the flow of air into the furnace, causing it to work harder to warm or cool the air. Not only will this increase your energy bill, but it can also cause the unit to overheat or break down, necessitating HVAC repair. 

A clean air filter is also necessary to preserve the air quality in your home. A dirty screen means contaminated air, which can exacerbate allergies and asthma symptoms.

How Do You Replace an Air Filter?

HVAC RepairTo replace the filter—which you should do every three months—first turn off the HVAC system. Locate the filter panel, which will most likely be well-marked on the bottom or side of the furnace, near the air intake duct.

Remove the old filter and confirm that the replacement filter is the correct size. If you aren’t sure which size filter to purchase, check the HVAC owner’s manual or the side of the current filter for the dimensions. Put the new filter in place, ensuring that the arrows printed on the side face the direction of the airflow. Replace the access panel and turn the HVAC system back on.
