How do I know if my Atlanta home's ducts need cleaning?

The strongest indicators are: visible mold in supply or return vents (common in Atlanta's humidity), excessive dust on surfaces within days of cleaning, musty odor when the HVAC runs, or a recent rodent or pest infestation. NADCA recommends against cleaning healthy ducts simply as a "routine" measure — cleaning should be triggered by confirmed contamination, not a schedule alone.

Will duct cleaning help with Atlanta's spring pollen allergies?

It can help if pollen has accumulated inside the duct system (typically through leaky return plenums or attic bypasses). However, duct cleaning alone will not address ongoing infiltration. Ask your contractor to inspect for air leaks at the air handler and at flexible duct connections to plenums — sealing these is often more effective than cleaning alone.

How long does a residential duct cleaning take in Atlanta?

A typical single-story Atlanta home (1,500–2,500 sq ft, 1 system, 10–15 vents) takes 2–4 hours. Two-story homes or dual-system homes take 4–6 hours. Jobs involving mold remediation, coil cleaning, or duct repairs will take longer. Confirm scope and time estimate before booking.

What is the NADCA standard for duct cleaning?

NADCA's ACR-2021 (Assessment, Cleaning, and Restoration of HVAC Systems) is the industry standard. It requires source removal — mechanically agitating debris and simultaneously vacuuming with a HEPA or high-efficiency truck-mounted machine. Non-compliant companies may use a "blow-and-go" method (compressed air without simultaneous vacuum) that redistributes, rather than removes, debris. Ask contractors specifically whether they follow ACR-2021.

Should I choose a $99 duct cleaning coupon deal?

No. The Better Business Bureau and EPA both warn against low-cost duct cleaning coupons. These offers are often bait-and-switch tactics: the technician quotes expensive add-ons (mold treatment, biocides, UV lights) once in the home. A legitimate Atlanta duct cleaning for a standard home costs $300–$550. Below that, ask detailed questions about scope and NADCA certification.
