Duct Cleaning in Bethesda, MD
Montgomery County · ZIP 20817
Bethesda's 20817 is dense with mid-century brick colonials, many original to the late 1950s through early 1970s. That means floor registers, in-wall trunk runs, and air handlers tucked into tight basement closets. Many homes in Burning Tree and Bannockburn have HVAC systems that were retrofitted at least once, which leaves abandoned duct sections collecting dust behind drywall patches. We work the live runs, document everything, and tell you honestly if a section is sealed off and not worth the air. Same flat pricing — no Bethesda upcharge, no fuel fee.
$279 each additional system · $15/vent over 10

Common questions from Bethesda homeowners
Do I need to be home?+
Yes — we need access to vents and the air handler. Plan on 2–3 hours. Work from another room, we stay out of your way.
Is it messy?+
No. We run a sealed negative-air system — all debris is pulled into a truck-mounted HEPA vacuum. Floors covered, tools clean, we leave the space the way we found it.
How long does it take?+
Two to three hours for a standard home with one HVAC system. Larger homes or multiple systems add 30–45 minutes each.
Do you move my furniture?+
No. We work around it. Clear the vent areas and we handle the rest.
Is it safe for my pets?+
Yes. No chemicals, quiet equipment. We suggest keeping pets in a separate room during the service so they're not startled by the vacuum.
What equipment do you use?+
Truck-mounted HEPA vacuum, rotating agitation brushes, and sealed negative-air containment. Every piece follows the NADCA ACR standard.
