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.

AfterFast, Reliable Air Duct Cleaning Across Bellevue
Air duct cleaning for a typical single-system home in Bellevue runs $350 – $650, with multi-system properties in West Bellevue and Clyde Hill often ranging $800 – $1,400 depending on total runs and access difficulty. Our crews dispatch from the Seattle office and carry Rotobrush rotary systems and Nikro negative-air machines through Bellevue daily, from the split-levels of Lake Hills to the high-rises downtown. Call (361) 326-5060 for a written estimate before any work starts.
We’ve worked in Bellevue long enough to know the ductwork tells the story of the house it sits in. The 1960s split-levels around Crossroads and Lake Hills carry original galvanized ducts through crawlspaces that never dry out. West Bellevue teardowns reveal sealed-off runs from ramblers built in the 1950s. Downtown condos stack vertical chases twenty stories high. That variation is why our Air Duct Cleaning team prices per system, inspects with cameras, and documents everything in writing before we pack up.
Why Hollis Air Duct Cleaning Is Bellevue’s Preferred Air Duct Cleaning Company
Bellevue homeowners call us after they’ve watched a coupon special turn into a bill twice the quoted price at the door. We don’t work that way. Roy Castellanos built Hollis Air Duct Cleaning on The Garrison Standard: written price, written guarantee, technician accountability. Every job gets the 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit.
Our technicians are background-checked and uniformed. You know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, seven days a week. No callback queues. No “we’ll get to you Monday.” Scheduling is coordinated from our Seattle office, and crews carry professional-grade equipment from Rotobrush, Nikro, and filtration products from Aprilaire and Abatement Technologies. Not hardware-store vacuums with brushes glued on. The same tools commercial crews use on hospitals and schools.
We know Bellevue’s permitting quirks for high-rise HVAC access, the moisture problems in Lake Hills crawlspaces, and why a three-system Clyde Hill custom home can’t be priced like a Kirkland ranch. That local fluency saves homeowners from surprises.
Vent Cleaning in Bellevue
Vent Cleaning in Bellevue means more than wiping registers. Supply vents push conditioned air into your rooms; return vents pull air back to the handler. Both collect skin cells, pollen, construction dust, and in Bellevue’s damp climate, mold spores that settle on vanes and in the short runs behind the wall. We remove each register, agitate the duct with rotary brushes, and extract debris under negative pressure so nothing blows into the living space. A typical vent cleaning for a standard Bellevue home with 10 – 15 registers runs $180 – $340.
Supply Vent Focus
Supply vents are where you feel the air. In West Bellevue homes with recent remodels, we’ve found drywall dust packed two feet into supply runs from construction crews who never capped the lines. We brush and vacuum every foot, then verify airflow at the register.
Return Vent and Trunk Access
Return vents pull air through the largest openings in your system. Their trunks collect the most debris, and in Bellevue’s older homes they’re often oversized and poorly filtered. We clean the vent, the boot, and as far into the trunk as our equipment reaches, documenting with photos.
Air Duct Repair in Bellevue
Air Duct Repair in Bellevue is often discovered during cleaning, not before. In Lake Hills and Crossroads split-levels, our technicians routinely pull panels and find galvanized supply and return ducts in crawlspaces with heavy surface rust, separated seams, or collapsed flex from decades of condensation against damp soil. Cleaning compromised ducts just moves contaminated air through failing pipes. We flag damage with camera footage, quote replacement sections in writing, and complete source removal on the sound runs. Partial duct repair in Bellevue typically runs $400 – $900 depending on linear feet and material.
Crawlspace Duct Replacement
When galvanized ducts rust through or flex duct sags and tears, we replace sections with insulated flex or sheet metal as appropriate, seal with mastic, and test for leaks. The goal is a system that holds pressure after we leave.
High-Rise Chase Access and Repair
Downtown Bellevue condos present a different challenge. Vertical chases run through multiple units, and shared HVAC systems require building coordination for access. We work with property management to schedule shutdown windows, repair within code, and restore common-area access clean.
Trusted Brands We Service in Bellevue
Our trucks stock parts and filtration products from Aprilaire, Abatement Technologies, and Guardsman so Bellevue customers aren’t waiting on Seattle supply-house runs. Aprilaire media filters handle the pollen load that hits the Eastside every spring. Abatement Technologies HEPA filtration protects indoor air during active cleaning. Guardsman products finish duct sealing jobs with material rated for residential pressure. When a Lake Hills homeowner needs a filter upgrade or a Crossroads rental needs a vent replacement, we carry the inventory to finish same visit.
Common Air Duct Cleaning Problems We See in Bellevue Homes
- Multi-system pricing confusion in West Bellevue and Clyde Hill. Custom homes frequently run two or three air handlers for different zones. A bid quoting one system misses the extra runs, registers, and return trunks. We count systems and price per unit in writing before starting.
- Crawlspace corrosion in Lake Hills and Crossroads split-levels. Damp soil and poor ventilation rust galvanized ducts from the outside in. Cleaning without inspecting for structural compromise wastes money. We camera-inspect first.
- Construction debris in recently remodeled homes. The West Bellevue tear-down boom leaves drywall dust, wood particles, and insulation fragments in ducts that were open during framing. New homeowners move in and breathe it for months.
- Undocumented work in downtown high-rises. Vertical chases and shared systems hide cleaning quality from residents. We provide before-and-after camera footage so owners know what was actually removed.

FAQs About Air Duct Cleaning in Bellevue
Because the original 1960s galvanized ductwork in your crawlspace is likely corroded from decades of condensation against damp soil. We camera-inspect to find rust, separation, or collapse before we clean. Cleaning structurally compromised ducts just pushes air through holes. Call (361) 326-5060 and we’ll show you what the camera sees before quoting repair or cleaning.
Each system has its own air handler, duct runs, registers, and return trunks. We price per system, not per vent, so a three-system home typically runs $800 – $1,400 versus $350 – $650 for a single-system house. The written quote counts your systems and lists the work for each. No mid-job surprises.
Before-and-after camera inspection footage of every accessible run, plus a written completion summary with system pressure readings if applicable. In high-rises with shared chases, you can’t see the work yourself. We document so you know what was removed and what condition the ducts are in. Ask for it if another company skipped it.
Bellevue’s damp, cool climate means heating systems run 8 – 9 months yearly, and condensation in poorly insulated ducts promotes mold and mildew growth you won’t see at the register. Pollen and mold spores accumulate year-round rather than being flushed by dry heat. Musty odors when the furnace kicks on are often the first sign. Call (361) 326-5060 if you’re noticing that smell.
Yes. We use source-removal methods consistent with NADCA guidelines, including negative-air containment with HEPA filtration from Abatement Technologies equipment, rotary brush agitation, and proper protective procedures for the work area. The 365-Day Done Right Promise covers the work in writing. If it’s not done right, we make it right at no charge.
