Indoor Air Quality Testing in Glastonbury, CT
What Our Air Quality Testing Measures
Indoor air quality testing looks at what’s actually floating around inside your home, not just what you can see or smell. Our technicians measure humidity, carbon dioxide, dust, particulate matter, and common pollutants such as mold spores and volatile organic compounds. In Glastonbury, seasonal humidity swings can play a big role in how these factors show up in your home.
We also check airflow and ventilation, since a home that isn’t circulating air properly can trap pollutants indoors. Testing gives you a clear picture of what’s happening in your air so you can make informed decisions about your home’s health, rather than guessing based on symptoms alone.

Signs Your Home May Have Air Quality Problems
Poor indoor air quality doesn’t always announce itself, but there are some common signs to watch for.
- Persistent musty odors
- Increased allergy symptoms indoors
- Visible mold or mildew
- Excess dust on surfaces
- Condensation on windows
- Family members feeling fatigued at home
- Uneven humidity throughout the house
Our Air Quality Testing Process
Our technicians begin by walking through your home to understand your layout, ventilation setup, and any specific concerns you’ve mentioned. From there, we use specialized equipment to measure humidity, temperature, particulate levels, and other air-quality indicators across different areas of your home.
Once testing is complete, we review the results with you in plain language, pointing out anything that raises a concern. In many Glastonbury homes, a humidity imbalance is common, especially in homes with older HVAC systems or limited ventilation. If we identify an issue, we’ll walk you through your options, whether that’s a whole-home dehumidifier, an air purification system, or improvements to your existing HVAC setup.

Common Pollutants and Issues We Detect
Every home is different, but there are a handful of issues we see often in our area. Humidity imbalance is one of the most common issues, particularly during Connecticut’s humid summer months, when excess moisture can lead to mold growth and musty odors. On the flip side, winter heating can significantly dry out indoor air, which can affect comfort and even damage wood furniture or flooring.
We also frequently detect dust and pet dander buildup, especially in homes with older filtration systems that aren’t capturing particles effectively. Mold spores are another common finding, often linked to humidity issues or poor ventilation in bathrooms, basements, and crawl spaces. Volatile organic compounds from household products and building materials can also show up in testing, particularly in newer or recently renovated homes.
