Air duct cleaning in Smithtown.

Yes. We clean dryer vents in Smithtown homes, from the back of the dryer to the outside vent cap. Most homes need it about once a year. Long vent runs with several bends trap lint faster and may need it more often.

Air duct cleaning in Smithtown runs $449–$649 for a typical 2,500–3,200 sq ft center-hall colonial with a 3-zone HVAC system, which is very common here. Three-zone homes require more time and equipment — we quote per job after the free scope. Smithtown homes built in the 1970s–1990s on Nissequogue River Road, Lawrence Road, and similar neighborhoods typically have moderate-to-heavy duct debris.

Every 3–5 years is the NADCA standard. For the larger Smithtown colonials with three HVAC zones, pet-owning households, or anyone dealing with seasonal allergies, we recommend every 2–3 years. We service all of Smithtown including Nesconset, St. James, Kings Park, and Hauppauge ZIP codes.
