How to Change Your Air Filter

Allergy season is here, and your air filter plays a big role in the air you breathe at home. 🏡💨 As pollen levels rise and dust becomes more noticeable, your HVAC system works harder to keep your indoor air clean and comfortable. One of the simplest yet most effective ways to support it is by regularly changing your air filter. Not only does this improve air quality, but it also helps your system run more efficiently and last longer.

If you’ve never changed your air filter before, don’t worry—it’s a quick and easy process. Start by turning off your HVAC system. This is an important safety step that also prevents unfiltered air from circulating while you’re replacing the filter.

Next, locate the air filter. In most homes, it can be found near the return vent or inside the air handler unit. If you’re unsure, a quick check of your system’s manual or a look around common areas like hallways, basements, or utility closets should point you in the right direction.

Once you’ve found the filter, check its size. The dimensions are usually printed on the frame of the existing filter. Using the correct size is crucial for proper airflow and filtration, so be sure to match it exactly when purchasing a replacement.

Now comes the replacement step. Carefully remove the old filter and take note of the direction of the airflow arrows printed on the frame. Insert the new filter in the same orientation, ensuring it fits snugly in place. This ensures your system filters air effectively without straining.

Finally, turn your HVAC system back on and enjoy cleaner, fresher air throughout your home.

Changing your air filter regularly—typically every 1 to 3 months—can make a noticeable difference, especially during allergy season. It helps reduce airborne allergens like pollen, pet dander, and dust while improving overall system performance.

This small maintenance task can have a big impact. By keeping your air filter fresh, you’re not just protecting your HVAC system—you’re creating a healthier, more comfortable space for you and your family all season long. Call LINS for a AC check and clean and make sure you are ready for summer.
