Measure first, then decide what to fix.
Before buying a purifier or a humidifier, find out what the air actually contains. Testing for particles, humidity, carbon dioxide and more points to the right fix.
- Measures: Humidity, temperature, particles, CO2
- Inspects: Filters, ducts, returns, coils, moisture

What it is, and why it matters.
Air quality complaints are vague: a stuffy feeling, headaches, a musty smell, dust that returns the day after cleaning. Without measurements it is easy to buy the wrong fix. Testing shows humidity, temperature, particle levels, carbon dioxide and, where appropriate, other indicators, and finds patterns by room and time of day.
Nashville HVAC performs indoor air quality assessments across Middle Tennessee. We combine measurements with an inspection of the system, filters, ducts, returns and moisture sources, then explain findings and options in plain words. Where a problem needs a specialist, such as mold testing or a gas safety issue, we say so and refer you.

Indoor Air Quality Testing: common questions
Can you test for mold?
We measure humidity and look for moisture sources and visible signs. For lab mold testing or remediation, a specialist is the right resource, and we can point you to one.
What is a healthy indoor humidity level?
Many aim for roughly thirty to fifty percent. Our Comfort Map shows how temperature and humidity combine.
