Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning Company in Bellevue, WA
Air duct cleaning in Bellevue typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a week and completed in a single visit. What makes Bellevue different from nearby markets is the housing stock itself: decades of damp Pacific Northwest climate layered inside original ductwork, plus a wave of West Bellevue tear-downs exposing sealed systems that haven’t moved air since the 1960s. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews handle Bellevue’s mix of high-rise condos, mid-century splits, and renovation-triggered abatement calls. Call (361) 326-5060 for a free estimate.
Why Bellevue Homes Are Different
Bellevue’s damp, cool climate means heating systems run eight to nine months a year. That near-constant use, combined with poor insulation in crawlspaces and attics, creates condensation inside ductwork that you simply don’t see in drier markets. We’ve pulled rotary brush heads out of galvanized trunk lines in Lake Hills that were half-filled with mildew sludge from twenty years of slow moisture buildup.
The West Bellevue tear-down boom adds another layer. In Clyde Hill, Medina, and Newport, remodelers and custom builders routinely uncover old ductwork in 1950s-60s ramblers that’s been sealed up for decades. Those systems need cleaning and abatement, but they also need careful assessment: asbestos tape, degraded fiberglass, and collapsed flex runs are common. It’s work triggered by demolition or renovation rather than routine maintenance, and it requires technicians who know what they’re looking at before the first brush turns.
East of I-405, the 1960s-70s split-levels in Crossroads and Lake Hills present their own pattern. Original ductwork runs through unheated crawlspaces where damp soil corrodes galvanized pipes and promotes mold growth. We regularly find ducts that aren’t just dirty but structurally compromised, needing partial replacement before cleaning can even begin. Downtown Bellevue’s high-rise condos, built since the 1980s, bring the opposite challenge: vertical duct chases and shared HVAC systems that need specialized access equipment and coordination with building management.
Our Main Bellevue Services
Bellevue homeowners call us for three core services, each with its own local conditions and equipment demands.
Air Duct Cleaning in Bellevue
Our Air Duct Cleaning in Bellevue covers the full system: supply and return trunk lines, branch ducts, and registers. In Bellevue, we typically deploy Rotobrush rotary brush systems for residential mains and Nikro negative-air machines for larger homes or post-renovation jobs where debris volume is high. The damp climate here means we check for mold and mildew at every access point, not just surface dust. Written price before we start, every time.

Dryer Vent Cleaning in Bellevue
Our Dryer Vent Cleaning in Bellevue addresses a fire-safety issue that worsens in cool, humid weather when dryers work harder and lint compacts. Bellevue’s older split-levels often have vent runs that exceed twenty feet through crawlspaces, creating multiple low points where moisture and lint collect. We use rotary whip tools and high-velocity vacuums to clear the full run, then verify airflow with a meter. No per-vent pricing: one flat price per system, agreed before work starts.

Duct Sealing in Bellevue
Our Duct Sealing in Bellevue targets the leaks that waste heated air into crawlspaces and attics, a major efficiency loss in homes that run heat most of the year. We use mastic and metal-backed tape on accessible joints, plus aerosol sealant for internally coated systems where manual access is limited. In Bellevue’s older stock, we often find original duct tape that’s dried and fallen off entirely, leaving gaps that pull musty crawlspace air straight into living spaces.

What keeps them predictable: we write the price before any work starts, and that number does not move at the door. The Garrison Standard requires it.

FAQs About Air Duct Cleaning Company in Bellevue
High-rise and condo buildings in downtown Bellevue typically require 24 – 48 hours notice to building management for rooftop or mechanical room access.

Most Bellevue appointments book within three to five business days. Post-renovation or abatement jobs may need additional lead time for proper containment setup. We do not promise same-day dispatch; duct cleaning is a scheduled job, and we arrive inside the window we quote.
Yes. Our Bellevue coverage includes West Bellevue neighborhoods like Clyde Hill and Medina, plus Eastside areas including Crossroads and Lake Hills.
