Indoor Air Quality Testing in North Atlanta, GA

What Does Air Quality Testing in Atlanta Measure?

Air quality testing in Atlanta measures what is floating in the air inside your home: fine particles, humidity, VOCs and CO2, room by room. Fresh Cleaning Solutions runs these tests across North Atlanta and walks you through every number before we leave, so you know what is wrong and what fixes it.

Here is what each reading tells you, and why it tends to run high in homes on the north side:

Why Is Indoor Air in North Atlanta Homes So Hard to Keep Clean?

Atlanta calls itself the city in a forest, and a 2023 Georgia Tech study measured tree cover at about 46% of the city's land. The northern suburbs are just as wooded. Those trees are beautiful, and every spring they coat driveways, cars and return vents in yellow dust. On March 29, 2025, Atlanta Allergy and Asthma recorded a pollen count of 14,801, the highest ever measured in the metro. Whatever your filter misses settles in the ducts and blows back out for months.

Then summer brings the humidity. The Chattahoochee River runs along Roswell, Sandy Springs and Johns Creek, and the creeks and wooded lots around it keep crawl spaces damp from June through September. Most North Atlanta ductwork runs through those crawl spaces or through hot attics, where small gaps pull in moist, dusty air.

Housing age adds to it. Much of the housing around the Perimeter went up in the 1970s and 1980s, and in Dunwoody the 1970s is the single biggest building decade. Many of those homes are on their second or third AC system but still run on the original ducts. That is why indoor air quality testing so often turns up high particles and high humidity in the same house.

Book a test if you notice:

• Allergies that get worse at home and better when you leave
• Dust back on the furniture a day or two after you clean
• A musty smell when the AC kicks on
• Headaches or a stuffy feeling after new paint, floors or cabinets
• A crawl space that feels damp in July and August

How Does a Home Air Quality Test Work?

A home air quality test with us is one visit, and you get the answers on the spot. No waiting on a report that shows up weeks later.

1. Test the air. We measure particles, humidity, VOCs and CO2 in the rooms you use most and write down every reading.
2. Inspect the vents and ducts. We remove and check vent covers and look at the supply and return lines so we know where the problem starts.
3. Walk you through it. We show you each number, explain what is high and why, and tell you what would fix it.
4. Quote the fix. If something needs work, you get a free estimate and a flat rate up front, no hidden fees.

If the smell or the readings point to mold, mold testing is a separate test. We take air samples and check for moisture in the rooms, attic, crawl space and ductwork, then send the samples for lab analysis so you know if mold is in the air and where it is coming from.

What Happens After Your Air Quality Test?

A test is only worth it if it leads to the fix. Because we do the cleaning and drying too, the same team that found the problem solves it:

• High particles: air duct cleaning with HEPA-filtered negative air and rotary brushes on every line, plus free dryer vent cleaning
• High humidity: a whole-house or crawl space dehumidifier, or crawl space encapsulation to keep out the damp
• Musty smell: mold testing first, then mold remediation if it is confirmed
• Pollen and allergies: UV lights and whole-home air purifiers to keep the air cleaner between visits

Want the test and the fix in one trip? The Home Air Quality Check bundles the air test, whole-home duct cleaning, a free dryer vent cleaning and sanitizing into one visit.
