Understanding the Importance of regularly Changing Your HVAC Filter

Why Change the Filter?

  • Air Quality: Over time, the HVAC filter traps dust, pollen, pet dander, and other airborne contaminants. A clogged filter can lead to poor indoor air quality, aggravating allergies, and respiratory issues.
  • Efficiency: A dirty filter restricts airflow, making the HVAC system work harder. This can increase your energy bills and reduce the system’s lifespan.
  • System Health: A clogged filter can lead to issues like freezing of the air conditioning unit or overheating of the furnace.

Selecting the Right Filter Size and Type

Before replacing the filter, you need to know the correct size and type for your system.

Finding the Right Size: Check the old filter for size markings, which are usually printed on the frame. Typical sizes include 16×20, 20×25, or 16×25 inches.

Choosing the Right Type:

  • Disposable Fiberglass Filters: These are the most basic and least expensive. They primarily protect the HVAC equipment but do not improve air quality significantly.
  • Pleated Filters: Made from polyester or cotton, they trap more particles than fiberglass filters.
  • HEPA Filters: High Efficiency Particulate Air filters can trap at least 99.97% of dust, pollen, and smoke particles.
  • Washable Filters: These can be cleaned and reused, but they may not provide as good filtration compared to disposable ones.

Step-by-Step Guide to Changing Your HVAC Filter

  1. Turn Off Your HVAC System: Before starting, turn off your system to ensure safety.
  2. Locate the Filter: In most residential homes, the filter is located inside the HVAC unit or inside a return air vent on a wall or ceiling.
  3. Remove the Old Filter: Slide it out carefully, paying attention to the direction arrows on the frame.
  4. Check and Clean the Area: If there’s any loose debris in the area where the filter sits, clean it out before placing the new filter.
  5. Insert the New Filter: Ensure the arrows on the frame (indicating airflow direction) match the direction of the system’s airflow. Slide the filter into place.
  6. Turn the HVAC System Back On.

Common Mistakes to Avoid

  • Using the Wrong Size Filter: Ensure you have the correct size, so there are no gaps that allow unfiltered air to pass through.
  • Forgetting the Airflow Direction: Always check the arrows on the filter frame.
  • Not Checking the Filter Periodically: Even if you have a set schedule, check your filter from time to time.

Frequency of Changing Your HVAC Filter

  • Basic Fiberglass Filters: Every 30 days
  • Pleated Filters: Every 3-6 months
  • HEPA Filters: Consult the manufacturer’s guidelines
  • Homes with Pets or Allergy Sufferers: More frequent changes might be needed.
