Causes of Clogged Air Filters

Causes of Clogged Air Filters

Here are possible reasons why your air filters could become clogged.

When your HVAC system is operating efficiently, it keeps your home comfortable all throughout the day. Not only does it keep your home at the right temperature, but it also keeps your air clean so that people can breathe happily. This can change, however, if your air filters get clogged. When your filters get clogged, the air quality in your home can go down, and it becomes harder to regulate the temperature of your house.

That’s why it’s important to identify potential reasons for clogging as quickly as possible, so that you can resolve the problem, and get your filters working properly again. Here are possible reasons why your air filters could become clogged.

Pet Hair

For those who have pets, you’ll want to keep in mind that pet hair has the ability to clog up your air filters more quickly than you may expect. This is especially true when temperatures get warmer, and your pets may shed thicker coats of fur in order to form thinner coats. To help prevent this problem, make sure to brush your pets weekly, and keep up with vacuuming so that hair doesn’t have the chance to get to your filters.

Dusty House

Dust is a problem that every home encounters, and it contributes greatly to air filter clogs if left unchecked. Whatever dust doesn’t get addressed will make its way to your filters, eventually causing clogging to occur. You can keep this problem in check with weekly dusting and vacuuming.

You Have Your Fan Set to “On” Rather Than “Auto”

If the fan on your thermostat has been set to “auto”, it means that your fan will only run if it needs to change the temperature of your home. Switching from “auto” to “on” means that your fan will constantly push air through your air filter. That’s why you should switch your fan to the “auto” setting if you want your air filters to last longer.
