Air Quality Testing in Kingsport, TN

When a house is at the right temperature and still uncomfortable, the cause is almost always humidity, filtration or something the ductwork is quietly drawing in.

We start with the ductwork, because it is the most commonly missed cause. Leaking return ducts in a crawlspace pull unfiltered crawlspace air — damp, dusty and occasionally worse — straight into the system and distribute it through the house. That air enters downstream of your filter, so a better filter cannot catch it.

Next is humidity, which swings both ways in this climate. Summer damp makes a cool house feel clammy and encourages mold; winter dryness irritates airways and cracks woodwork.

Then we look at filtration and ventilation: whether your filter is capturing what it should, and whether a tightly built house is getting enough fresh air.

Our job is to find the cause. If the answer is a ductwork repair rather than an air purifier, that is what we will recommend.

What that includes

• Return ductwork checked first — often the real cause
• Humidity measured, summer and winter
• Filtration evaluated for airflow as well as capture
• Ventilation assessed in tightly built homes
• Carbon monoxide testing where fuel is burned
• Recommendations based on your system, not a product list
