Tip: Preventative maintenance protocols can extend the lifetime of your air conditioning equipment. Changing air filters regularly is an important part of managing your home’s air quality and the efficiency of your system.

Air filters are an important part of your central air conditioning system and are often under-appreciated for what they accomplish. They collect bits of pollen and dust that would have otherwise circulated throughout your home. Air filters really are the first line of defense and clogged air filters are the number one cause of HVAC system failure.

All of the air handled by the HVAC system passes through the air filter at some point. As it catches more of the natural debris in your home (dust, mold, fungal spores, pet dander, fabric fibers, etc.), the fine mesh through which air passes becomes denser. This means that if you do not change your air filter regularly, air will not be able to pass through.

What you can do:
During times of heavy use, if you have pets or live in a high pollen area, your air filters should be inspected every 30-60 days to make sure unwanted dust and dirt have not collected or clogged up your system.

Dirty Air Filters Can Cause:

  • Your blower to work harder to push air, drawing more energy and shortening its expected lifespan.
  • A reduced amount of air in the living areas you need it most.
  • Overheating or freezing up of the equipment.
  • A place for moisture to build up leading to the growth of mold.
  • A collection of dust and debris throughout your ductwork.

You may find it necessary to replace air filters sooner than the usual 3-month mark during these times, in which case it is important to keep a few backup filters handy just in case. Understanding some of the reasons your filters clog up faster than your neighbors can help improve your system’s performance.
