When it comes to HVAC units, regular maintenance should be top priority. If you keep your unit clean and check for issues regularly, you’re more likely to avoid a huge repair bill (or complete replacement) later. Changing your air filters regularly may seem like a bit of a hassle, but dirty air filters can wreak havoc on any HVAC system. If you’re wondering how often you need to complete this task, here’s a little cheat sheet to help you out.

Fiberglass Filters

If you use fiberglass filters on your systems, you should change them every month. These filters are usually the thinnest you can buy, so they get dirty pretty quickly.

Pleated Filters

Pleated filters are much thicker than fiberglass ones, and they have zig-zag patterned pleats that trap dirt and dust, so they generally last a lot longer than fiberglass filters. These high-efficiency filters can be changed every three months. They cost a bit more upfront, but they can save you money and time in the long run.

Washable Filters

Some people are lucky enough to have washable filters with their units. If you’re in this situation, just clean them once a month or so. 

Other Factors to Consider

While these are all the general guidelines, there are a few other things to consider, as well. You should change or clean your filters more often if you: 

  • Have pets
  • Have a large household or have children
  • Smoke
  • Have an older, dusty home
  • Don’t vacuum regularly
  • Notice a lot of dust buildup on your filters

​By the same token, if you don’t have pets or children, vacuum regularly, and have a newer home, you may be able to change your filters less frequently. If you have questions about your HVAC or would like to schedule maintenance, contact Smoak’s Comfort Control online or at 843-556-9550 today.
