Can you guess the question we’re asked most by Central Florida homeowners?

If you guessed:

“How often should I change my AC filter?”

Then you’re right!

But before we answer this question, let’s explore more about how your AC filter plays an important part in keeping your Central Florida home cool and comfortable all year round.

Why is it important to change my AC filter?

Changing your AC filter is one of the quickest and easiest ways to keep your AC unit working properly.

Your AC filter is key to keeping your indoor air quality at its best, because it traps dust, dirt and pollen that’s circulating in the air before it reaches the inside of your home. It also protects you from the risk of larger objects (such as bits of loose insulation) being pulled into your system and causing damage.

What happens if I don’t change my AC filter?

A dirty AC filter is bad news for your home—and your pocket. If your filter is already filled with trapped particles, the blower fan in your HVAC unit has to work harder to push air through—which could mean a higher energy bill for you!

Because of the extra strain they put on your system, clogged AC filters are actually the leading cause of HVAC system failure. So to avoid a costly repair bill make sure you change your filter regularly!

How do I change my AC filter?

You can buy replacement AC filters at any home improvement store, and many groceries stores also carry them.

To learn what size you need, look at the numbers printed on the side of your existing filter: it will say something like 16x25x1. Make sure you insert your new AC filter the right way round—look for the air flow arrow on the side of the filter for guidance.

And finally, the all-important question:

How often should I change my AC filter?

As a general rule, it’s best to change your home’s AC filter every 90 days.

However, there are some important factors you should also consider to determine how often to change your AC filter. They include if anyone in your family has allergies, the number of pets in your household, the size of your home, and more. We recommend contacting a qualified HVAC company to learn more.
