Air filters are typically made out of spun fiberglass or pleated paper and surrounded by a frame made of cardboard. They are placed into a specific place in the HVAC systems and function as a barrier to prevent contaminants and other particles from circulating in the air, or from reaching sensitive parts of the system. Some of the common things that filters block are dust, pollen, lint, mold, hair, animal fur, bacteria, etc. Most homeowners don’t think about their HVAC system until it stops functioning the way that it should be. One of the major sources of a system complication or failure is clogged air filters. Read on to learn more about how air filters work, and the serious consequences that can happen when they aren’t changed on a regular schedule.

Why You Need To Change Your Air Filter


Depending on the type of air filter that you utilize, there are different schedules to ensure that the filter is always functioning for optimal performance. The majority of manufacturers recommend that basic filters are changed every 30 to 60 days, but circumstances that could affect these guidelines include having pets or allergies. When air filters are not changed regularly, particles and contaminants build up and clog the filter. Even though the filter is designed to accommodate these minuscule items, the buildup will create an almost impenetrable barrier so that the air is unable to flow through completely, which can ultimately cause many problems for the entire HVAC system. Some major problems include:

  • Higher energy bills- When the filter gets clogged, air is unable to flow easily through the system, causing the whole system to have to work on overdrive in order to distribute heat or air properly. This ramps up your utility bills since the air is running for longer. 
  • Poor temperature regulation- As clogged air filters strain the system, warm or cool air may not be able to adequately flow where it is required. This means that some rooms could be too cold during the winter or too hot in the summer, all the while you’re paying the same (or more) in utilities.


We Provide HVAC Repair


Why you need to change your air filters before looking for “HVAC companies near me”:

  • Health problems- If the air filter is clogged and unable to trap contaminants as it did before, then these contaminants can go back in the air that everybody is breathing in your home. Some immediate issues can include headaches, itchy eyes or throat, and dizziness. Long-term, there could be respiratory diseases, heart disease, or cancer.
  • Furnace failures- If the system is working harder to get around clogged air filters, the entire system could overwork and break. This can cost anywhere from four to twelve thousand.
