5 Consequences of Not Changing Your Air Filter

Changing your air conditioner (AC) air filters is a quick and easy process that can be done in minutes. Yet, many homeowners forget to perform this routine task and end up running into problems. Some wait for their HVAC technician in Birmingham to replace them during routine maintenance every 6 to 12 months. This poses a risk for several problems since these filters need to be replaced several times a year.

What are AC air filters?

Air filters for your heating and cooling system are placed at the air handler and in the returns. They may look like simple cardboards and mesh coverings, but these cool air accessories perform a vital function. Filters are designed to clean the air that passes through the system. When air is forced through the filters, the particles, allergens, and other contaminants get trapped and remain within the meshed fibers. Types of particulates and contaminant include: 

  • Dust and dirt
  • Lint and fibers
  • Animal hair or fur
  • Mold and mold spores
  • Pollen
  • Tiny metal, wood, or plastic particles
  • Bacteria and other microorganisms

How Often You Should Replace AC Air Filters

Clean air filters are necessary to keep your HVAC system running efficiently. Experts recommend homeowners change the filters at least every 45 days and no later than 90 days after the last replacement. You can do it yourself. Check whether the filters are dirty or clogged by holding each one up to sunlight or interior light. Change them if you can’t see the light shining through. Just ensure you replace them with the right size and type of filters. If you’re not sure what to do, have your HVAC professional in Birmingham perform filter maintenance for you.

5 Problems Caused by Clogged or Dirty Air Filters

Failure to keep clean filters in your heating or cooling equipment may lead to the following issues:

  • Damage to your heating and cooling unit or HVAC system malfunctions from built-up dust, dirt, and contaminants in your HVAC system’s ductwork<
  • Reduced airflow inside the HVAC system or hot air coming through your vents.
  • Excessive wear and tear on your unit parts from having to work harder to cool your home.
  • Increased energy usage and a spike in monthly energy bills from overworking the HVAC equipment.
  • Poor Indoor Air Quality and Potential Health Problems

Clogged Filters and Poor Indoor Air Quality

Air filters help protect your home’s air quality by trapping and holding dust, dirt, debris, allergens, and other contaminants. Failure to change the air filters as recommended will cause built-up particles, allergens, and contaminants to release back into your home air. This can increase the risk of health problems such as allergy symptoms, asthma, and other respiratory problems caused by airborne particles.
