Allergic to Air Conditioning? How to Improve Your Indoor Air Quality

by | Apr 2, 2025 | Air Conditioner, Indoor Air Quality

If air conditioning makes you sneeze or leaves you with watery eyes and a scratchy throat, you’re not imagining it. Your AC can blow around stuff like dust, mold, pet dander, and pollen that might trigger your allergies. No worries, though—we’ve got easy fixes to help you breathe better and keep your home cool and fresh!

Can You Be Allergic to Air Conditioning?

Even though you can’t technically be allergic to air conditioning, it sure can feel like it sometimes. When your AC runs, it circulates air throughout your home—but if it’s not properly maintained, it can also spread allergens like dust or mold spores. Here’s why your AC might be making your allergies worse:

1. Dirty or Old Filters

Air filters are supposed to trap allergens, but if they’re dirty or not designed to catch tiny particles like pollen or mold, they can actually push allergens back into the air.

2. Clogged Air Ducts and Vents

Over time, dust, debris, and even mold can build up in your ducts and vents. When your AC blows, so do those allergens—right into your living space.

3. High Humidity

Too much moisture in your AC can lead to mold and mildew, which love to spread their spores around your home. And guess what? Those spores can trigger allergies and breathing issues.

4. Skipping Regular Maintenance

If you’re not keeping up with routine cleaning and servicing, allergens will pile up, and your AC won’t run as efficiently. That means worse air quality for you.

Keep your AC clean and well-maintained, and your allergies might just thank you!

Common AC Allergy Symptoms

Think your AC might be messing with your allergies? Here are some common signs to watch for:

  • Sneezing or a stuffy nose
  • Itchy, watery eyes
  • A scratchy throat
  • Coughing fits
  • Worsened asthma
  • Trouble breathing comfortably

How to Cut Down Allergies from Your AC

Good news: with a few easy tweaks, your AC can help you breathe cleaner, allergen-free air. Here’s how to make it happen:

1. Upgrade Your Air Filters

If you’re still using basic filters, it’s time to step it up. Go for a high-quality filter, like a HEPA filter, which can catch tiny particles like mold and pet dander. Check out our selection of air filters to find the perfect fit for your needs. Just don’t forget to swap it out every 1-3 months to keep things running smoothly!

2. Stay on Top of Maintenance

Your AC needs a little TLC, too. Regular tune-ups are key to keeping it clean and allergy-friendly. A Five Star AC technician is happy to help clear out dirt and allergens from the coils, fan blades, and ducts.

3. Control the Humidity

Too much moisture in your home? That’s a recipe for mold. A whole-home dehumidifier can keep humidity levels in check (below 50% is ideal!) and improve your air quality.

4. Try Air Purifiers

Looking for extra protection to improve your indoor air quality? Consider adding an air purifier to your home. For example, the iWave-R® can tackle allergens, bacteria, pathogens, funky odors and more. It’s a good choice for families or anyone looking to enhance the air they breathe at home.

5. Clean the Ducts

Dust and debris like to hide in your vents and ductwork. A professional cleaning can clear it all out. And if you’ve got mold in there, calling an HVAC expert is a must.

6. Boost Ventilation

Good airflow makes a big difference. Crack a window when the outdoor air quality isn’t bad, use exhaust fans, and set your blower fan to “on” instead of “auto” to keep clean air moving through your home.

With these tips, you’ll be well on your way to an AC that helps you breathe easier!
