Trusted Air Duct Cleaning for Seattle Homeowners
Air Duct Cleaning - Seattle typically costs $350-$850 for a complete residential system and is usually completed in a single visit. Most Seattle homeowners schedule service every 3-5 years, or sooner when dust buildup, musty odors, or allergy symptoms increase after our wet winters.
We’ve been providing the Best Air Duct Cleaning in Seattle, WA since 2012. That’s more than 42 years of pulling decades of dust, construction debris, and Pacific Northwest moisture out of ductwork in Craftsman bungalows in Wallingford, mid-century ramblers in Wedgwood, and newer builds in Ballard and Queen Anne. Colin Merritt leads our operation, and we still answer the phone with a live person 24 hours a day, not a menu tree. Our technicians are background-checked, uniformed, and arrive in marked vehicles. Every job starts with a camera inspection of your ductwork, and every job ends with one too, so you see the difference instead of taking our word for it. We quote one honest price before we lift a single tool, and we back our work with a 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing. Call (833) 700-5198 for a free estimate.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential duct cleaning removes accumulated dust, pet dander, pollen, and debris from the supply and return ducts that circulate air through your home. In Seattle, we regularly find significant buildup in homes built before 1990, especially those with original fiberglass ductboard or unsealed metal joints that have drawn in attic or crawl space air for decades. Our team uses professional-grade Rotobrush and Nikro equipment to agitate and extract debris without damaging delicate older ductwork, and we complete most single-family homes in one visit.

Commercial Duct Cleaning
Commercial duct cleaning addresses the larger, more complex HVAC systems found in Seattle’s multi-tenant buildings, retail spaces, restaurants, and small offices. These systems run longer hours and accumulate grease, paper dust, and construction particulate at different rates than residential setups. We scale our crew and equipment to your building’s square footage and occupancy schedule, working evenings or weekends if needed, and we provide before-and-after camera documentation for property managers and building owners.

Supply Duct Cleaning
Supply duct cleaning targets the pathways that deliver heated or cooled air from your furnace or air handler to each room’s vents. When supply ducts are clogged, you get weak airflow, hot or cold spots, and your HVAC system runs longer to compensate. We see this frequently in Seattle’s hillside homes in Magnolia and Queen Anne, where long duct runs and multiple stories create natural pressure challenges that worsen with any blockage.

Return Duct Cleaning
Return duct cleaning clears the larger trunk lines that pull air back to your system for reconditioning. These ducts are your home’s breathing intake, and they’re often the dirtiest because they lack the filtration that protects supply lines. In older Seattle neighborhoods like Capitol Hill and the Central District, we’ve pulled out everything from deteriorated filter material to decades of accumulated fireplace ash and remodeling dust from return trunks that haven’t been opened since the Carter administration.

Full System Cleaning
Full system cleaning covers supply ducts, return ducts, the air handler cabinet, blower assembly, and coil compartment as a single coordinated service. This is what most Seattle homeowners actually need, though some competitors quote only partial cleaning to hit a lower price. We inspect the entire system with our camera first, show you what we find, and quote the complete job upfront so there are no surprises when we open additional components.

Video Inspection
Video inspection is the foundation of every service we provide, not an upsell. We run a high-resolution camera through your ductwork before cleaning to document existing conditions and identify any damage, disconnected joints, or pest intrusion. After cleaning, we run the camera again so you can verify the results yourself. This visual record protects both of us, and it’s why our 90-Day Done Right Promise rarely needs to be invoked, our customers in Seattle know exactly what they paid for.

Brands We Service for Air Duct Cleaning
We’ve serviced and cleaned ductwork connected to hundreds of Honeywell and Aprilaire air cleaning systems throughout Seattle and the Eastside. We understand how these whole-house units integrate with your ductwork, where their media filters sit in the airflow path, and how to clean around their electronic components without causing damage. Our technicians carry common replacement parts and can spot when a filter housing seal has failed, letting dirty air bypass the media entirely.
We also regularly work with Abatement Technologies and Guardsman equipment, particularly in homes where prior owners installed commercial-grade negative air machines or where mold remediation required specialized HEPA filtration. Whether you have one of these brands or any other make, we can help. Our camera inspection reveals the condition of your ductwork regardless of what’s connected to it, and our cleaning process adapts to metal, fiberglass, flex duct, or hybrid systems.
Signs You Need Air Duct Cleaning Right Now
- Visible dust blowing from vents. If you see particles puffing out when your system kicks on, your ducts are actively distributing debris through your living space. This often worsens in Seattle’s dry summer months when lower humidity keeps particles airborne longer.
- Uneven heating or cooling between rooms. When some rooms never reach temperature while others overshoot, restricted airflow from duct buildup is a common cause. We’ve traced this to partially blocked supply lines in older Seattle homes where decades of accumulation have narrowed effective duct diameter by 30% or more.
- Musty or stale odors when the system runs. Pacific Northwest moisture creates ideal conditions for microbial growth in ductwork, especially in homes with crawl space or basement air handlers. The smell hits when the blower disturbs what’s growing on the duct walls.
- Increased allergy or respiratory symptoms indoors. If you or family members notice more sneezing, congestion, or irritated eyes at home than elsewhere, your ducts may be recirculating concentrated allergens. This is particularly relevant in Seattle’s tree-pollen seasons when open windows already challenge indoor air quality.
- It’s been more than five years since your last cleaning, or you’ve never had one. Ductwork doesn’t clean itself, and every year of operation adds another layer of settled debris. In homes with pets, recent remodeling, or located near major Seattle thoroughfares like I-5 or Aurora Avenue, the accumulation accelerates.
Our Air Duct Cleaning Process - Step by Step
- 1
Camera inspection and assessment. We arrive at your Seattle home, introduce ourselves, and immediately run our video camera through your accessible ductwork. You watch the feed with us. We identify problem areas, note any damage or disconnected runs, and determine the appropriate cleaning approach for your specific system type.
- 2
Upfront pricing, no surprises. Before any equipment enters your home, we present your exact price in writing. The number we quote is the number on your invoice. This is our founding promise, and it’s how we’ve operated since 2012. No bait coupons, no mid-job add-ons, no pressure.
- 3
Protect your home, access the system. We lay protective covering on floors and furniture near work areas, then create sealed access points in your ductwork using industry-standard practices. For homes in Seattle’s older neighborhoods with original plaster or lath, we take extra care to minimize intrusion and restore surfaces properly.
- 4
Agitate, extract, and clean. Using Rotobrush contact cleaning for flex duct and Nikro negative air machines for rigid metal trunk lines, we dislodge debris and pull it out of your system entirely, not just redistribute it. We clean registers, grilles, and accessible components of the air handler. The process typically takes 3-5 hours for an average Seattle home.
- 5
Post-cleaning verification and cleanup. We run the camera again so you can see the results. We seal all access points, remove our protective materials, and leave your home as we found it, except for the ductwork. You receive documentation of the work performed, and our 90-Day Done Right Promise goes into effect automatically, no paperwork required on your end.
How Much Does Air Duct Cleaning Cost in Seattle?
Affordable Air Duct Cleaning in Seattle, WA runs $350-$650 for homes up to 2,500 square feet with a single furnace and standard duct configuration. Larger homes in neighborhoods like Laurelhurst or Magnolia with multiple zones, additions, or complex attic-and-crawl routing typically fall in the $550-$850 range. Commercial duct cleaning is quoted individually based on square footage, system complexity, and access constraints.
Several factors affect your specific price. The number of supply and return vents matters more than total home square footage, a compact home with many small rooms and vents can take longer than an open-concept layout. Accessibility is significant in Seattle’s hillside homes and those with finished basements where ductwork is concealed. The condition of your ducts affects time on job, heavily contaminated systems or those with pest intrusion require more intensive work. Additional services like dryer vent cleaning, duct sealing, or sanitizing are quoted separately and only if our inspection shows they’re needed.
To avoid overpaying, be specific about your home’s details when you call, and ask whether the quoted price covers the full system or only partial cleaning. Some competitors advertise low opening prices that don’t include return ducts, the air handler, or even all supply vents. Our quote covers what your system actually needs, and we show you the camera evidence before you decide.
Your free estimate includes the camera inspection, a written quote with no expiration pressure, and our honest assessment of whether cleaning will solve your concern or if a repair or sealing issue needs attention first. Call (833) 700-5198 to schedule.
