With our long summers, Texans often stay closed up with the A/C running for months at a time, collecting dust, allergens, and other pollutants. Even if the weather "cools", these issues can stick around. Poor Indoor Air Quality (IAQ) can lead to symptoms like sneezing, itchy eyes, coughing, and even fatigue. It can aggravate allergies, asthma, and cause other respiratory conditions.

Common Indoor Air Pollutants in Texas Homes

The Texas climate brings its own set of indoor air quality challenges. Here are some of the most common pollutants that Texans may face:

  • Dust and Pet Dander: Keeping up with cleaning after pet can cause homes to collect a lot of pet hair and dander.
  • Growth and Mildew: Texas humidity can lead to bacterial growth in areas with poor ventilation.
  • Pollen and Other Allergens: Ragweed, cedar, and other Texas allergens can easily make their way indoors and stay trapped in enclosed spaces.

Signs of Poor Indoor Air Quality

Poor IAQ isn't always visible, but it can cause symptoms that make themselves known. Here's what to look for:

  • Recurring sneezing, coughing, or dry eyes while at home.
  • Persistent headaches or feeling tired even when well-rested.
  • Allergy symptoms that flare up more indoors than outdoors.

Tips to Improve Indoor Air Quality in Texas Homes

Luckily, there are some effective ways to improve your home's air quality without too much hassle:

  • Ventilate Regularly: On cooler, low-pollen days, crack a window or two to let fresh air in. Ventilation helps reduce the buildup of indoor pollutants.
  • Maintain Your HVAC System: Regular HVAC maintenance is essential, as these systems circulate air throughout your home. Change air filters, especially if you have pets, and schedule seasonal tune-ups every 6 months to keep the system running smoothly.
  • Use Air Purifiers & UV Lights: In high-traffic or allergy-prone areas like bedrooms and living rooms, air purifiers can help capture dust and allergens. UV lights prevent microbial buildup on air filters, cooling coils, drain pans, and duct surfaces.
  • Control Humidity: Texans know that humidity can make things feel like you just took a shower after walking outside. Keep indoor humidity between 30-50% to prevent bacterial growth and stay comfortable.


Indoor air quality might not be the first thing on your mind as the Texas heat beats down on you, but it plays a big role in your home's comfort and your family's health.
