What Happens When You Don’t Change Your HVAC Filter?

The Importance of HVAC Maintenance

At Timothy Off, our Malvern heating and cooling experts are always reminding our customers to change their HVAC filter. This should be done every one to three months, depending on your living situation. But what happens when you don’t change it? In this blog, we list a few things that may occur:

Reduced Airflow

A clean HVAC filter means your system will have a clear path for the warm or cool air to travel, and a clear path means efficient airflow. If you don’t change your filter, all of the dust, dirt, allergens, and particles that are trapped in the filter will block the flow of air, reducing the amount of air that’s circulated throughout your home.

Dirtier Air

If your HVAC filter is dirty, it means that the air that is passing through the filter isn’t getting filtered much. This leads to dirty air being pumped throughout your home (as well as dirty air ducts) and it means you and your family are breathing it. Dirty air can not only irritate your eyes, nose, and throat, but it can also worsen existing health problems like bronchitis or asthma.

System Stress

A dirty, blocked-up filter certainly doesn’t help your HVAC system. In fact, if you don’t change your filter, your system will have to work harder in order to efficiently heat or cool your home. Working harder on a regular basis causes stress to your system and it could ultimately shorten its lifespan.

Increased Bills

Because your HVAC system has to work harder to make your home comfortable, it will be turning on more often and running longer cycles. This results in a higher energy bill for you.
