Why Changing Your AC Filter Is Essential for Summer Comfort

What Happens if You Don’t Change Your Air Conditioner’s Filter?

Enjoying Summer... Until You Step Indoors

Summer is the perfect season to be outside—grilling, swimming, playing with the kids, or working in the yard. But after a long, hot day in the sun, nothing beats the comfort of walking into a cool, air-conditioned home.

So what happens when that refreshing blast of cold air is missing?

If your cooling system is underperforming, the issue might be as simple—and as frustrating—as a dirty air filter.


What Does an Air Filter Actually Do?

Air filters play a vital role in maintaining indoor air quality and helping your HVAC system run efficiently. They trap dust, pollen, pet hair, and other airborne particles before they can enter your system or circulate throughout your home.

Over time, however, these filters become clogged—especially if:

  • You have pets

  • There’s a lot of foot traffic

  • You live in a dusty area

  • You haven’t changed your filter in a while

A clogged filter restricts airflow and forces your system to work harder. That leads to higher energy use, more wear and tear, and poor indoor comfort.


4 Big Problems Caused by a Dirty Air Filter

1. Health Risks from Poor Indoor Air Quality

According to the Environmental Protection Agency (EPA), indoor air pollution can lead to:

  • Eye, nose, and throat irritation

  • Headaches and fatigue

  • Dizziness or nausea

  • Worsening asthma and allergies

A clogged filter allows contaminants to remain in your air—negatively impacting your health.


2. AC System Damage

When airflow is restricted, your system can overheat, leading to:

  • Compressor damage

  • Frozen coils

  • Shortened equipment lifespan

  • Uneven cooling and hot spots in your home

Replacing your filter regularly is a low-cost way to protect one of your home’s biggest investments.


3. Higher Utility Bills

A dirty filter forces your AC to use more energy. In fact, the U.S. Department of Energy estimates that replacing a clogged filter with a clean one can reduce energy consumption by 5–15%.

That’s an easy win for both your wallet and the planet.


4. Decreased Comfort

A poorly performing AC system means:

  • Weak airflow

  • Hot and cold spots

  • Longer run times

  • Constant thermostat adjustments

When your filter is clean, your entire home stays cooler, more evenly cooled, and far more comfortable.


How Often Should You Change Your Air Filter?

It depends on your system and lifestyle, but here are some general guidelines:

  • Every 30 days for basic fiberglass filters

  • Every 60–90 days for pleated filters

  • Every 20–45 days if you have pets or allergies

  • Check monthly during peak summer or winter months
