If you suspect mold in the AC or ductwork of a Lilburn home, turn the system off if you can, note what you see, and have the coil, pan, drain and duct runs inspected before anything is cleaned. Moldy fiberglass duct materials are replaced, not cleaned. Call the number on this page to be connected with a local mold remediation company in Lilburn.

Lilburn sits along US 29 in Gwinnett County, about 17 miles from Atlanta, with Old Town Lilburn at its center. Like most of the metro, its houses run air conditioning for much of the year, and ductwork often snakes through crawl spaces or attics where summer air is damp or very hot.
What to do now
- Shut the system off if the weather allows. EPA says running a system you know or suspect is contaminated can spread mold through the house.
- Look at the air handler. Standing water in the pan, a dripping drain line or wet insulation nearby points to the cause.
- Photograph vent covers, ceiling stains and the area around the unit before anyone cleans.
- Run a dehumidifier in the main living area if the house feels damp. EPA suggests keeping indoor humidity below 60 percent.
- Find out what your ducts are made of, or ask the company to tell you. Sheet metal and fiberglass are handled differently.
- If you rent, tell the landlord in writing and keep a copy.

Signs and what they usually mean
| What you see | Likely cause |
|---|---|
| Musty odor only when air is moving | Growth on the coil, in the pan or inside a duct |
| Black spotting on one supply register | Condensation on the grille, or a sweating duct behind it |
| Water on the floor by the furnace closet | Blocked condensate drain or cracked pan |
| Damp, crumbling duct board in the crawl space | Long-term condensation or a past water event |
Lilburn renters should know that city code enforcement officers work within the Lilburn Police Department and enforce the city's Property Maintenance Code; reports go through SeeClickFix or City Hall at 770-921-2210. Georgia law requires landlords to keep rentals in repair, and Georgia Legal Aid notes that includes keeping heating systems running and repairing air conditioning that comes with the unit. That is general information, not legal advice.
What moves the price
- Total length of ductwork that needs work, and whether it is metal, flex or duct board
- How tight the crawl space or attic is around the equipment
- Whether the coil, blower or pan needs repair by an HVAC technician
- Any drywall or insulation damaged by overflow water
- Whether clearance testing is done after cleanup
