How DocAir Tests Your Air
Once you call, the science begins. Here is how we reach the root cause, not just the symptom.
We install a monitoring device that documents temperature, humidity, CO2, particulates, VOCs, and carbon monoxide over time.
We collect air samples and send them for laboratory analysis at a certified lab.
We pinpoint the source of the problem, not just the contaminant, so it can actually be solved.
You get a clear, evidence-based report and a written proposal, never a scare-tactic upsell.
Every assessment is led by a Certified Industrial Hygienist. We diagnose first. That is the "Science before Sales" difference.

What Might Be Hiding in Your Home's Air
The air inside a home can be far more polluted than the air outside. EPA's guidance on indoor air quality notes that indoor pollutant levels often climb when ventilation is poor.
Dust, pet dander, and pollen tracked in from outside
Mold spores and bacteria from damp or humid areas
Smoke and combustion byproducts, including carbon monoxide
VOCs that off-gas from cleaners, carpet, furniture, and building materials
Radon, a colorless gas that seeps in from the soil below
Many of these particles get trapped in your HVAC system and recirculate, room to room, with every cycle.
How Poor Indoor Air Quality Affects Your Health
You may not notice the effects right away. Over time, though, contaminated air can trigger symptoms that look a lot like seasonal allergies.
The EPA links long-term exposure to some indoor pollutants with serious respiratory disease, heart disease, and even cancer.
Why Homes Face Unique Air Quality Risks
Radon is the big one. Davidson County sits in EPA Radon Zone 1, the highest-risk category, and the Metro Public Health Department reports roughly 40% of tested local homes had elevated levels, with a county average near 7.0 pCi/L.
The Nashville Basin's limestone and karst bedrock feed radon up through foundation cracks, and radon is the second leading cause of lung cancer in the US.
Per the Metro Public Health Department, many Middle Tennessee homes are built on crawl spaces rather than basements, letting air, moisture, and radon enter living areas through the stack effect. The EPA recognizes Davidson County as a potential high radon area.
With nearly 50 inches of rain a year and clay-heavy soil that holds water against foundations, moisture intrusion and humidity drive mold growth across the metro.
Historic East Nashville, Germantown, and Inglewood homes carry original foundations and ductwork never built for today's moisture loads.
Where testing finds elevated radon, DocAir can design a radon mitigation system sized for your home.

Call (615) 373-2498How much does air quality testing cost in Nashville?
Your initial evaluation with DocAir is free. From there, the testing scope depends on what your diagnosis calls for. Nationally, a professional air quality assessment runs roughly $300 to $600 for a standard home, with add-ons like radon or mold sampling priced separately. We scope only what your situation needs.
How long does air quality testing take?
According to the Metro Public Health Department, the Air Quality Index for Nashville is updated every weekday morning, but there is no information provided about the duration or procedures for on-site residential air monitoring visits. Laboratory analysis typically comes back within a few business days, followed by your written report.
What does an air quality test detect?
A full assessment can detect mold spores, VOCs, particulates, carbon monoxide, radon, and elevated humidity, and it also measures temperature and CO2. The goal is not just to confirm a problem exists, but to pinpoint its source so it can be corrected at the root.
What are the signs that I need air quality testing?
Persistent musty odors, headaches, congestion, or allergy-like symptoms that ease when you leave home are common signs. Visible mold, a damp crawl space, or a recent water issue are others. In Nashville, elevated radon is invisible, so testing is the only way to rule it out.
Does Nashville have a radon problem?
Yes. Davidson County is an EPA Radon Zone 1 area, and the Metro Public Health Department reports that about 40% of tested local homes had elevated radon. Because radon has no smell or color, testing is the only way to know your home's level and whether mitigation is needed.
