Kennesaw HVAC mold usually starts with condensate that does not drain, a wet coil or ducts sweating in attics and crawl spaces. Removal means fixing the moisture first and then cleaning or replacing the affected parts. Call the number on this page to be connected with a local mold remediation company in Kennesaw.
About Kennesaw
Kennesaw, about 23 miles northwest of downtown Atlanta, is a suburban city with railroad and Civil War history, home to Kennesaw State University and next to Kennesaw Mountain National Battlefield Park. Butler Creek runs through the area; in the September 2009 floods, the National Weather Service gauge on Butler Creek listed at Kennesaw crested at 14.27 feet against a 12-foot flood stage. Apartments commonly have a closet air handler, where a clogged drain line can wet flooring and drywall without anyone noticing for weeks. Houses add ducts in attics and crawl spaces, where cold metal meets humid air through most of the cooling season.
What to do now
- Turn off the system if you can. EPA advises against running one you know or suspect is contaminated.
- Check the pan under the indoor coil for standing water or rust.
- Make sure the condensate line is dripping outside on hot days.
- If the crawl space has taken on water, look at the ducts for wet or sagging insulation.
- Photograph growth on grilles, the cabinet and ducts.
- Use a dehumidifier to keep humidity under 60 percent while the AC is off.
Signs and likely causes
| What you see | Likely cause |
|---|---|
| Water on the floor near the furnace closet | Blocked drain or cracked pan |
| Mold ringing a ceiling register | Condensation at the outlet, or attic air leaking into the boot |
| Musty smell when the blower starts | Growth on the coil, pan or blower wheel |
| Wet duct wrap under the floor | Sweating ducts or water in the crawl space |
| Clammy rooms at a low setting | Oversized or short-cycling unit |
Cost factors
Angi's Atlanta cost guide reports HVAC system mold remediation at $3,522 to $11,740. The duct material has the biggest effect, since EPA says moldy fiberglass duct board or lined duct should be replaced rather than cleaned. Total duct length, attic and crawl space access, containment and repairs to the equipment follow. If ducts or equipment are replaced, or walls and ceilings opened, the City of Kennesaw Building Services Department takes permit applications online and books inspections through its portal; staff can also confirm whether a property is inside city limits. Kennesaw Code Enforcement handles private property concerns through the city's online portal.
