Indoor Air Quality
Indoor air quality (IAQ) testing measures the pollutants in your home’s air — dust, allergens, mold spores, humidity, and VOCs — so you know what you’re actually breathing and how to fix it. The U.S. EPA reports that indoor air can be two to five times more polluted than outdoor air, which matters because most people spend about 90% of their time indoors. Prestige Protected helps Triangle homeowners assess and improve their indoor air.

What is indoor air quality testing?
IAQ testing evaluates the air in your living space for common contaminants and conditions: particulates (dust, dander, pollen), mold and moisture, humidity levels, and volatile organic compounds (VOCs) from household products. The goal is to identify what is affecting your air and where it’s coming from, so the fix targets the source.
Signs of poor indoor air quality
- Allergy or asthma symptoms that worsen indoors
- Persistent dust on surfaces and at vents
- Musty or stale odors (see mold in air ducts)
- High humidity, condensation, or stuffy rooms
- Headaches or congestion that ease when you leave home
How to improve indoor air quality at home
The EPA’s three core strategies are source control, better ventilation, and air cleaning. In practice that means: remove or reduce pollutant sources (including cleaning ducts when there’s mold or heavy debris), use a good HVAC filter and proper ventilation, control humidity, and clean coils so the system runs well. We help you prioritize the steps that matter most for your home.

FAQ
Indoor Air Quality Testing — FAQ
Does air duct cleaning improve indoor air quality?
It helps when the ducts contain a real source of contamination — mold, pests, or heavy debris. For an already-clean system, filtration and humidity control matter more. The EPA recommends source control first.
How do I know if my home has poor air quality?
Watch for indoor allergy symptoms, persistent dust, musty smells, or high humidity. Testing confirms what’s present so you can target the fix.
