3 Problems Dirty Air Filters Cause In Your Home

If we’ve said it once we’ve said it a thousand times: regularly changing your air filters is the easiest and most cost-effective way to keep your HVAC running efficiently and effectively. But there are other benefits too! In this post we’ll explain how a dirty filter can cause major problems you may not even realize, and why keeping your filters clean can help you avoid all of those issues.


Air filters serve several purposes, but one of them is to keep your HVAC unit clean. As the air goes through your system, a filter helps separate the dirt so it doesn’t clog up the critical parts that make your system run properly!


Dirty filters create several negative impacts:

  • When the filter is filled with dirt, the air can’t pass through. This creates a reduction in airflow, and an increase in the time it takes for your home to reach its desired temperature. All that means an increase in running time and an increase in costs!
  • Inevitably, dirt will start entering the system. This means dirty coils, which prevents them from adequately cooling, and again causes the whole process to take longer.
  • Because a dirty filter makes your system work harder, not only does that cost you more to keep your home cool, but it also means the system can overheat and will eventually break down, leading to costly repair or replacement costs.


Many HVAC systems suggest changing your filters a minimum of once every three months. However, if you live in an area that tends to be windy or has dirt in the air, or if you notice dust in your home, or that your system seems to be running all the time, it’s advisable that you change your filters as often as once a month. This may seem tedious, but in the long term, it will equate to increased comfort and money savings.
