Indoor Air Quality Services - Is Your Home's Air Making You Sick? Signs you need IAQ Testing

Thursday, July 31st, 2025 by Evan Schmitt

5 Signs You Need Indoor Air Quality Testing

1. Frequent allergy or asthma flare-ups
Sneezing, congestion, coughing, or wheezing that worsens indoors? That could point to particulate matter—like dust, pollen, pet dander, or mold—floating in your air. Even radon gas clings to particulates and becomes more harmful when inhaled.

2. Lingering musty or chemical smells
Musty odors often mean mold growth (EPA Danger Level 4). Fumes from paints, cleaners, or new carpeting fall under toxic compounds (Level 1). These VOCs can lead to headaches, fatigue, or long-term health effects.

3. Visible mold or dampness
Mold isn’t just unsightly—it affects indoor air quality and can trigger respiratory issues. Excess humidity creates the perfect breeding ground.

4. Unexpected humidity problems
If basements or crawl spaces feel damp, that’s a red flag. Dehumidifiers and vapor barriers help control moisture levels.

5. You’re concerned about airborne germs
Especially after illnesses running through the household, airborne bacteria and viruses (Danger Level 2) are a worry. Advanced air cleaners or UV‑C lights can reduce these pathogens.

  3. Recommend tailored solutions — ERVs, air purifiers, dehumidifiers, UVC lights, or vapor-intrusion systems.

  4. Provide a clear, no-pressure, no-cost estimate.
