We’re Bellows Air Duct & Vent Co., and we’ve been driving out to Redmond from Seattle since 2012. We know the difference between a quick run up SR-520 at 10 a.m. and the crawl through downtown Redmond at 5:30. Our technicians are background-checked, uniformed, and carry the same Rotobrush and Nikro equipment that serious HVAC contractors specify. Calls come through to a live person, 24 hours a day, at (833) 700-5198. Most Redmond appointments are available within 48 hours, and we show up when we say we will.

Why Bellows Air Duct & Vent Co. of Seattle Is Redmond’s Preferred Air Duct Cleaning Company

Redmond homeowners call us because we’ve built a reputation on not needing to be called back. Our 90-Day Done Right Promise is stamped on every job: if the work isn’t right, we return at no charge, no paperwork, no arguing. That’s been our standard for over 42 years.

We answer the phone. Not a voicemail tree, not an app. A live person, day or night. Redmond customers tell us this matters because when you smell mold from your vents at 7 p.m. on a Tuesday, you want to talk to someone who can put you on the schedule.

Our pricing is disclosed upfront, before a single tool is lifted. The number on the phone is the number on the invoice. No bait coupons, no price changes at the door. We’ve seen what discount operators leave behind in Redmond homes, and we built this company as the square-deal alternative.

Every job gets a camera inspection before and after. You see what we see. In Redmond’s 98052 neighborhoods, that visual record often reveals the first evidence homeowners have of what’s actually living inside their ductwork.

Our Air Duct Cleaning Services in Redmond

Residential Duct Cleaning

Most of our Redmond calls come from homeowners in 1,800-2,800 square foot single-family homes built between 1986 and 1998. These houses went up fast to meet Microsoft demand, and the flex-duct branch runs were installed with cost-conscious speed. Excessive slack, multiple sharp bends around split-level floor plans, and improperly sealed joints have left systems trapping particulates for decades. We clean the full supply and return network, reseal accessible joints, and run a camera so you see the difference. Our Air Duct Cleaning team has cleared systems in Education Hill, Bear Creek, and Grass Lawn that hadn’t been touched since the original owner moved in.

Commercial Duct Cleaning

Redmond’s commercial base has shifted from pure tech to mixed-use development along Cleveland Street and Redmond Way. We clean ductwork for property managers, medical offices, and retail spaces with the same upfront pricing and camera documentation. Scheduling works around your tenants or patients. Most commercial jobs in Redmond finish in one visit, with minimal disruption to operations.

Supply Duct Cleaning

Supply ducts push conditioned air into your rooms. In Redmond’s prolonged damp season, these lines become prime territory for mold and biofilm, especially where flex-duct sags and creates low points that never fully dry. We use professional-grade Rotobrush equipment to agitate and extract debris, then verify with camera inspection. The Sammamish River valley microclimate traps marine moisture and fog 3-4 weeks longer each spring and fall than neighboring Kirkland or Sammamish. That persistent indoor humidity accelerates mold growth inside aging flex-duct systems. Supply duct cleaning without addressing that moisture context is half a job.

Return Duct Cleaning

Return ducts pull air back to your furnace. They collect the most debris because they’re the intake path. In Redmond homes with original 1990s construction, return plenums often show the heaviest biofilm buildup, especially if the system has run with a standard fiberglass filter for years. We clean the full return path, including the plenum and filter rack area, and document with before-and-after video.

Full System Cleaning

This is what most Redmond homeowners actually need. We clean supply ducts, return ducts, the furnace blower compartment, and the coil if accessible. One visit, one crew, camera verification throughout. Full system cleaning runs $550-$950 in Redmond depending on home size and system complexity. The homes in eastern Redmond, in 98053 around Redmond Ridge and Trilogy, often have multi-zone duct layouts that take longer but still typically finish in a single day.

Video Inspection

Every Bellows job includes camera inspection. We run a flexible borescope through your ductwork and show you the footage. In Redmond’s older neighborhoods, homeowners are often surprised by what we find in systems they assumed were clean. The video becomes your record of the work performed. We also offer standalone video inspections for Redmond homeowners who want to assess their system before committing to full cleaning.

Trusted Brands We Service in Redmond

We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same brands serious HVAC contractors specify for commercial and residential work. For Redmond customers, this means we have the right tool for your specific duct material and layout, whether that’s original 1990s flex-duct in Bear Creek or a newer multi-zone system in Redmond Ridge. We stock common fittings and sealants, so most repairs don’t require a return trip. Parts availability matters when you’re trying to get a job done in one visit, and we’ve built our inventory around what Redmond homes actually contain.

Common Air Duct Cleaning Problems We See in Redmond Homes

• “Too new to need cleaning” assumptions. Homeowners in 98052 assume their late-80s or 90s tract homes are too new for duct cleaning, ignoring that original flex-duct was installed with excessive slack and tight bends that trap debris for decades. Those systems are now 25-35 years old and largely unserviced.
• Missed antimicrobial treatment after cleaning. Crews unfamiliar with Redmond’s prolonged damp-season humidity in the Sammamish valley skip antimicrobial treatment, letting mold recolonize within weeks. The valley microclimate demands this step.
• Hidden sag points in split-level floor plans. Technicians who don’t know Redmond’s common split-level layouts miss flex-duct sag points that collect biological debris and never fully clean the system. In a 1992 tract home on Education Hill, our team used a Rotobrush to clear decades of biological debris from sagging flex-duct runs that had never been serviced. The homeowner was shocked the mold smell vanished after we removed biofilm from the return plenum and resealed multiple sharp bends.
• Heavy organic debris from surrounding canopy. The dense Douglas fir, red alder, and western red cedar around Redmond deposit pollen, spores, and fine organic debris into outdoor-air intakes during the dry-summer window when homeowners run systems with windows open.

Each area has its own housing stock and climate quirks, and we adjust our approach accordingly. The plateau homes in Sammamish dry faster than valley-floor Redmond.
