Reasons to Replace Your AC Filters

Maintaining your air conditioning (AC) system is an important part of keeping your home comfortable. One of the most essential tasks for keeping your AC in good condition is regularly changing the filters. These filters are responsible for trapping dust, dirt, and other particles that can cause damage to your system, but over time they become clogged and reduce their efficiency.

Signs You Need to Replace Your AC Filters

If you're wondering when it's time to change your AC filters, there are a few signs you should look out for. For example, if you notice an unexplained increase in energy bills or loud or unusual noises coming from the unit, it could be a sign that the filters need replacing. Additionally, if there's a decrease in air quality or uneven cooling throughout the house, this could also indicate that it's time to replace them.

How Often Should You Change Your Filters?

The frequency with which you should replace your AC filters depends on several factors such as type and amount of use. Generally speaking, disposable fiberglass or pleated paper filters should be replaced every 1-3 months while washable electrostatic ones may last up to 6 months before needing cleaning or replacement.

It's important to remember that replacing or cleaning your filter more often will help keep your system running smoothly and efficiently while reducing energy costs and improving air quality in the home.


Changing your AC filter regularly is an essential part of keeping your system running properly and ensuring a comfortable environment in the home. By being aware of the signs indicating when it's time for a new filter, you can help prevent costly repairs down the line.
