The Effects of a Dirty Air Filter Can Wreak Havoc on Your HVAC System

Air filters are the unsung heroes of the HVAC system. For most homeowners, they’re out of sight and out of mind. While they’re keeping dust, pollen, pet danger, mold spores and other airborne nasties out of your HVAC system, they’re also the gateway to good health for the furnace and air conditioner. And these heroes can turn to villains if you don’t pay attention: the effects of a dirty air filter can be pretty grim, indeed!

Think about this:

  • When air circulates through your house, it’s moving fast enough to pick up a certain amount of dirt, pollen and other particulates and carry them to the air filter. The air filter’s job is to catch and hold them for disposal. But if the air filter is clogged, it can’t hold any more, leaving it to circulate through your home.
  • If you think dirt in the ducts is bad, dirt inside the system is even worse. For example, when dirt builds up on the inside components of an air conditioner, the A/C can’t transfer heat as well as it should, and transferring heat is what an A/C is all about! It takes indoor heat and moves it outside where it belongs.
  • When air isn’t circulating well, the HVAC system’s fan has to push harder to get conditioned air where you need it. And the harder it pushes, the more strain the system is under, and the more likely it is to wear out or break! Not to mention the fact that you’re probably not happy with the trickles of cool air you’re getting.

  • 5 star review  CLIFF WAS AWESOME!!! After our AC unit wasnt cooling like it used CLIFF came to my home and did a phenomenal job. He was very professional and knowledgable. I work in the service field as well and noticed how clean and organized he kept his tools and material/parts he was removing and replacing. Parts were cleaned to the best of his ability due to it being a 21 year old unit. He did a fantastic job. Would definitely recommend SCOTTS to my neighborhood and google members. Now my house cools off in no time. Thanks again CLIFF and of course the SCOTTS TEAM.

  • 5 star review  We had a great experience With this company, starting off with our sales person Daniel, extending to the entire installation crew. I’m sorry that I don’t remember all the names of the technicians who installed our units, but each and every one of them was very courteous, professional, and informative. They did not leave the house until the job is done right, and I did take a long time because we do have an older house. They started the job at about 8:30 in the morning and finished at 10 PM. They cleaned up everything and made sure that there was a full explanation as to how to use the thermostat units and the app so that we could control all of the AC units from our cell phones. They also made sure to follow up after the installation to make sure that we were satisfied with the job. I would certainly recommend Scott’s for AC installation.
