Change Your Air Filter

Time: 5 minutes

Want your AC to beat the heat? Replace the air filter. Your filter is designed to keep your AC system clean, preventing breakdowns. Dust and other allergens can accumulate in the filter over time, restricting airflow, increasing energy use, and causing the unit to overheat.

A good rule of thumb is to change your filter bi-monthly.You can adjust the frequency to 1-3 months depending on the type of filter your AC system requires, how often you use it, and your sensitivity to allergens. You’ll want to change it more frequently if you have pets; pet hair and dander can clog a filter fast.

What’s in it for you?

  • Fewer repairs
  • Longer machine life
  • Improved efficiency
  • Improved air quality

How to Change Your Filter:

  1. Turn off your system. Air shouldn’t pass through the system while you’re changing out the filter. Dirt and debris can cause serious damage inside your machine.
  2. Locate your filter. Depending on the layout of your system, the filter could be located behind the main vent that lets cool air into the house, or inside the machine itself.
  3. Remove the filter. If the filter is located in a vent, you’ll likely need to pull back a set of fasteners to remove the filter from the housing. If your machine uses a larger media filter, you’ll need to snap off the filter cap (a metal or plastic housing) to access the filter.
  4. Identify your filter type, and replace with the exact same size. Most filter measurements are represented as length x width x depth. Some AC systems require a custom filter, and will have a part number written on the filter.
  5. Install the new filter. Write the date on your new filter and gently slide it into place. Filters are designed to allow air to flow in a particular direction, so pay special attention to the arrow telling you which side to put in first.
  6. Put the cover back on and turn on the machine.

Pro Tip: Look for the minimum efficiency reporting value, or MERV, on your filters. The higher the number, the more efficient the filter is in trapping airborne particles. However, higher MERV ratings also require more energy to pull air through the filter. You’ll want to balance your air-quality concerns with energy costs.
