HVAC & Air Duct Mold Removal in Newnan, GA

Signs the AC system is involved

• A musty odor that arrives with the airflow, then fades
• Growth on ceiling diffusers in older plaster ceilings or newer drywall
• A drip pan that holds water or shows rust
• Ductwork in the crawl space with wet, sagging insulation
• Ceiling stains near an attic unit after storms

Local conditions in Newnan

Newnan, the Coweta County seat about 34 miles southwest of Atlanta, is known for antebellum and early 20th-century homes that were largely spared in the Civil War. Many older houses were not built with ductwork; systems were added later, often snaking through crawl spaces and attics with long runs and tight bends. That layout makes condensation and hidden leaks harder to spot, and joints in old retrofit ductwork often leak damp crawl space air straight into the return. Where the air handler sits in the attic, as it does in many newer homes, a clogged drain can overflow onto ceilings.

Storms matter too. An EF4 tornado struck Newnan in the early morning of March 26, 2021, causing substantial structural damage, including in the historic downtown. Roof damage from any storm can let rain into attics and onto the ducts and equipment there; if repairs were made but the ducts were never checked, they are worth a look.

The City of Newnan Building Department at 25 LaGrange Street issues permits, including minor repair permits, inside city limits. Ask whether replacing ducts or equipment needs one.

What affects the cost

Angi's Atlanta cost guide reports HVAC system mold remediation at $3,522 to $11,740; HomeGuide's 2026 national range for HVAC systems or ducts is $2,000 to $10,000. Long duct runs in older homes, duct board that must be replaced, tight crawl spaces and repairs to the unit push costs up.

What happens when you call

You are connected with an independent local company. Expect questions about where the unit is, the age of the house and system, and any storm or leak history. A visit should include the air handler, drain, coil and accessible ducts, plus a written plan.
