How To Change HVAC Air Filter

Changing your air filter maximizes the lifespan of your unit, helps keep your air clean, and reduces your energy consumption. With those clear benefits, prioritizing your air filter changes seems like a no-brainer. However, studies by the Department of Energy found that 29% of American homeowners never change their air filters and only 31% of homeowners who do change them, do so every few months. When these surveyed homeowners were asked about the importance of filter changes, only 43% said they felt filter changes are important. Our team at Parker’s Heating and Air has witnessed firsthand the difference that regular filter maintenance makes. Filter changes are a simple step you can take to conserve energy, preserve your unit, and prioritize your indoor air quality.

Recommended Filter Maintenance Schedule

Air filters should be checked monthly to ensure proper airflow. Although replacement is necessary at least every three months, sometimes changing it on a monthly basis is necessary. For example, if your family has an indoor pet, the pet dander could cause the filter to become clogged sooner. Families with elderly people or allergy sufferers should also consider earlier filter changes to ensure optimal air quality. 

Why Air Filters Matter

The air filter performs an important role in the air conditioning process. The filter captures dirt, debris, particulates, pollutants, and contaminants. A faulty or clogged filter will allow these particles through and compromise your unit and air quality. An air conditioning unit will be more likely to fail prematurely or become clogged when the filter is old, damaged, or dirty. Airflow is crucial for keeping your unit running smoothly and maintaining your home’s comfort settings. 

Additionally, a dirty filter will limit airflow and cause your HVAC system to be overworked. Your HVAC unit should last approximately fifteen years and will likely last longer with the proper maintenance. According to the EPA, a properly functioning HEPA air filter can capture up to 99.7% of 0.3 micron particles, including dust, mold, pollen, bacteria, and more. Remember to check and change your filter regularly for the sake of your HVAC’s life and the health of your family. 

How to Change your Filter

What if you don’t know how to change your filter? It’s pretty easy. Just follow these simple steps:

  • Shut off your HVAC unit.
  • Open your unit’s access panel. 
  • Remove the old filter.
  • Make sure your replacement filter is exactly the same size printed on the cardboard frame of your existing filter.
  • Slide in your new filter following the arrows on the filter.
  • Close your access panel.
  • Switch back on your HVAC unit.

Air filter changes are generally a straightforward DIY task. After you change your filter, mark your calendar or set a reminder to make sure that you check on it next month. If you have any trouble with replacing your filter, our experts at Parker’s Heating and Air are standing by to help.
