Breathe Easier

A 10-Minute DIY Project That Helps Your Air Conditioner

When August temperatures soar, your air conditioner works overtime to keep your home comfortable. One of the easiest ways to help it run more efficiently takes just 10 minutes—checking and replacing your HVAC air filter.

A clean air filter improves airflow, helps your system run more efficiently, reduces wear and tear, and can even improve your home’s indoor air quality.

Why Your Air Filter Matters

As your filter collects dust, pollen, pet hair and other airborne particles, airflow becomes restricted. When that happens, your HVAC system has to work harder, leading to:

• Higher energy use

• Increased wear on your system

• Reduced cooling performance

• Poorer indoor air quality

Step 1: Turn off your HVAC system.

Switch your thermostat to “Off” before removing the filter.

Step 2: Locate the filter.

You’ll usually find it behind a return air grille or inside the furnace or air handler.

Step 3: Inspect the filter.

If it’s dirty or little light passes through it, it’s time for a replacement.

Step 4: Install the new filter.

Make sure the airflow arrow points toward the HVAC unit.

Step 5: Check it regularly.

Inspect your filter monthly during cooling season and replace it every one to three months, depending on your home and lifestyle.

Choosing the Right Filter

Use the filter size and rating recommended by your HVAC manufacturer. A filter that’s too restrictive can reduce airflow and decrease system performance.

Small Task, Big Benefits

Changing your air filter is one of the simplest ways to improve your HVAC system’s efficiency. Combined with annual maintenance and smart energy habits, this quick DIY project can help keep your home comfortable while reducing energy use.

Take a few minutes this month to check your air filter. Your air conditioner—and your electric bill—will thank you.
