Signs of poor indoor air quality include persistent stuffy or stale air, allergy and asthma symptoms that ease when you go outdoors, lingering odors, condensation on windows, mold or mildew visible in bathrooms, excessive dust on surfaces, and headaches or fatigue that improve when you leave the house.

Common warning signs

  • Stuffy or stale air, especially in mornings
  • Allergy or asthma symptoms inside
  • Lingering cooking, pet, or musty smells
  • Condensation or fog on windows
  • Mold or mildew in bathrooms, closets, basements

Pinpoint the cause with an indoor air quality test, then layer improvements like duct cleaning and duct services.
