What Happens if You Do Not Change Your HVAC Air Filters Regularly? Insight from a Batavia Heating and Air Conditioning Company


Most homeowners do not pay much attention to their HVAC system until it stops working properly. However, breakdowns can be avoided easily with some regular maintenance. While this may sound like a headache, the most common cause of an HVAC system malfunction is quite easy to fix. The air filters can be the source of many problems if they are not changed regularly. Here is why:

How often should you change your air filters?

Air filters are usually composed of pleated paper or spun fiberglass, and they are placed within the HVAC system in areas where they can act as a barrier that prevents dust, particles, and other contaminants from entering the air cycle. The air filter will commonly block harmful or unpleasant particles such as animal fur, hair, mold, lint, pollen, dust, and bacteria.

Most basic air filters will need to be changed after 30 to 60 days of use according to manufacturers, but there may be other factors that come into play:

  • If you live in a home with no pets, the filters can be changed once every 90 days.
  • If you live by yourself with no pets, or the HVAC system does not see much use over a period of time, the interval can be anywhere from 6 months to one year.
  • If you do own pets, the air filters will need to be replaced every 60 days.
  • If you own more than one pet, or if someone in the home currently suffers from any allergies, it is best to change the filters more often than recommended, at an interval of around 20 to 45 days.

The consequences of not changing your air filters regularly

Over time, the filters will collect all the particles and contaminants that flow through the system. This is by design. However, as the filter collects more and more of these small items, the particles start to clog up the pores of the filter, and they create a barrier that hinders air flow. This ultimately leads to several problems within the entire HVAC system, including:

  • Higher energy bills – Because the air cannot flow easily through the system, the AC unit or the heater must work overtime to reach the temperature set by the thermostat. This increases your energy bills since the system must run longer and at a higher intensity.
  • Poor temperature regulation – Clogged air filters cause irregularities in the temperature distribution throughout the home. Not only does your system have to work harder, but it works harder and it does not reach the right temperature. This results in warmer temperatures in the summer, and colder temperatures in the winter.
  • Health issues – Clogged filters are less effective at removing contaminants from the air, which can lead to health issues—especially for people with allergies. When the air filters are clogged, residents may experience itchy eyes, sore throat, dizziness, headaches, and even long-term issues if the filters remain unchanged for an extended period of time.
