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.

Why Hollis Air Duct Cleaning Is Redmond’s Preferred Air Duct Cleaning Company
Redmond homeowners know the difference between a coupon crew and a company that prices in writing. We’ve built our reputation in this market on The Garrison Standard: arrive inside the quoted window, price the job before touching equipment, finish by the book, and leave the site clean. Our technicians are background-checked and uniformed, and our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
The 365-Day Done Right Promise backs every job we do in Redmond. If the work fails within a year, we return and make it right at no charge, including a free second visit. That promise is written down on every invoice, not implied. Roy Castellanos, who leads Hollis Air Duct Cleaning, insists on this standard because homeowners between 35 and 65 in suburbs like Redmond have been burned before by prices that jumped at the door and crews who vanished after the check cleared.
We coordinate scheduling from our Seattle office, but our crews know Redmond’s housing stock: the 1980s – 1990s subdivisions with original flex duct, the 2010s+ townhomes packed with multi-floor runs, and the damp climate that turns construction debris into musty problems faster than dry eastern Washington ever would.
Commercial Air Duct Cleaning in Redmond
Commercial Air Duct Cleaning in Redmond covers office parks near Redmond Town Center, medical suites, retail spaces, and multi-tenant buildings where HVAC downtime means lost revenue. We use Nikro negative-air machines and Rotobrush rotary systems to dislodge and extract debris from supply and return trunks without shutting down your building for days. A typical commercial system in Redmond runs $800 – $2,400 depending on square footage, duct accessibility, and whether video inspection is required for insurance documentation.
Office and Retail Systems
Redmond’s tech corridor offices run climate control around the clock, and that constant cycling pulls particulate through ductwork faster than residential systems. We schedule after-hours or weekend service to avoid disrupting your floor, and we document before/after conditions with photos you can show to property managers or tenants.
Multi-Tenant and HOA Properties
Shared HVAC in Redmond townhome associations and small commercial plazas requires coordination with multiple stakeholders. Our crew arrives with written scope and pricing, so every unit owner sees exactly what work was performed and what the flat price covers before we start.
Air Duct Cleaning Services in Redmond
Air Duct Cleaning Services in Redmond include full system cleaning, supply and return duct cleaning, video inspection, and duct sealing with mastic for homes from Education Hill to the newer builds near Bear Creek. We use Rotobrush rotary brush systems for mechanical agitation paired with negative-air extraction to pull loosened debris out of your home entirely, not just redistribute it. A typical residential job in Redmond runs $350 – $650 for a single-system home, with larger homes or multi-zone systems toward the upper end.
New Construction and Townhome Specialists
Redmond’s 2010s+ townhomes, built for tech workers on tight lots, pack three floors of flex duct into narrow chases. That aggressive routing means more joints and sags. A camera inspection almost always finds construction debris the builder never cleared. In Redmond’s damp climate, that new-construction dust mixes with moisture and turns into musty odors that owners mistake for a ventilation problem.

Older Home Flex Duct Assessment
Original 1980s – 90s builder-grade flex duct in Redmond’s older subdivisions is notorious for sagging and disconnecting at joints. We inspect for attic air leaks that show up as increased dust and higher energy bills, then seal with mastic where appropriate after cleaning.

Trusted Brands We Service in Redmond
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are professional-grade tools, not hardware-store gear. For Redmond customers, this means we can source replacement filters, media, and sealing materials without waiting on national shipping delays. If your system uses Aprilaire media filters or a Honeywell electronic air cleaner, we stock the correct sizing and can install during the same visit as your duct cleaning. Guardsman-treated components add durability in Redmond’s humid conditions where standard materials degrade faster.
Common Air Duct Cleaning Problems We See in Redmond Homes
- Construction debris in new townhomes. Builders in Redmond’s 2010s+ developments routinely leave drywall dust and wood particulate in supply and return ducts at handover. Homeowners assume a new house is clean and delay service until the blower motor is coated white and airflow drops.
- Moisture-locked dust from damp winters. Redmond’s rainy autumns and mild, humid winters keep construction dust moist instead of letting it dry and blow through. It sticks to duct walls and promotes biological growth and musty odors that don’t occur in drier climates like Spokane.
- Sagged flex joints in older subdivisions. Original 1980s – 1990s flex duct in neighborhoods near Education Hill and Overlake sags between supports and disconnects at collars, pulling unconditioned attic air into your system and spiking energy costs.
- Missed debris in multi-floor runs. Redmond townhomes with three floors of ductwork have more joints and direction changes than single-story homes. A quick pass with basic agitation tools misses debris lodged at flex connections. Only camera inspection and proper negative-air extraction catch it all.
Pricing for Air Duct Cleaning in Redmond, WA
A typical residential air duct cleaning in Redmond runs $350 – $650 for a complete single-system home. Multi-zone systems, homes with separate basement and main-floor units, or properties requiring camera inspection for insurance or HOA documentation run $550 – $950. Commercial systems start around $800 and scale with square footage and access complexity.
What moves the price: number of supply and return vents, whether your system uses hard duct or flex duct (flex takes longer to clean properly), accessibility of the air handler, and whether we find construction debris or mold requiring source removal beyond standard cleaning. We give one flat price per system, agreed in writing before work starts. No per-vent add-ons. No price jump when the van is in your driveway.
Every estimate is free. We inspect your system, explain what we found, and write the price down. You decide. Call (361) 326-5060 to schedule.

FAQs About Air Duct Cleaning in Redmond
Yes. We find construction debris in nearly every new Redmond townhome we inspect, especially multi-floor builds with complex duct runs. Drywall dust, wood particulate, and even fast-food wrappers get left behind by builders. In Redmond’s damp climate, that debris turns musty within months. Call (361) 326-5060 for a pre-move-in inspection and exact quote.
Redmond’s year-round mild, damp climate means ducts here are more prone to biological growth and musty odors than the dry dust accumulation common in Spokane. Moisture locks debris to duct walls instead of letting it pass through, so cleaning requires more thorough agitation and extraction. Our Rotobrush and negative-air setup is configured for these conditions.
Sagging between supports, disconnections at joints, and attic air leaks that raise your energy bill. Original 1980s – 90s flex duct in Redmond subdivisions was built to a lower standard than today’s materials. We inspect with cameras and seal with mastic where the duct is salvageable. If replacement is needed, we tell you directly. Call (361) 326-5060 for an assessment.
We use Rotobrush rotary brush systems, Nikro negative-air machines, and filtration from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, maintained to manufacturer spec, and explained in plain terms on every job. No mystery equipment. No rental-grade gear.
We provide before-and-after photos of your own ductwork, taken with our inspection camera and shown to you before we pack up. You see the debris we removed and the condition of the duct after cleaning. Combined with the 365-Day Done Right Promise, you have documentation and a written guarantee. Call (361) 326-5060 to schedule your free estimate.
