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 Kenmore
Air duct cleaning in Kenmore typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch crews from our Seattle office and serve Kenmore neighborhoods directly, including the Sammamish River corridor, Inglewood-Finn Hill, and the hillside homes above Juanita Drive. If your home was built between the 1950s and 1970s and still runs original galvanized steel ductwork, you’re looking at a 50 – 70 year old system that needs inspection before any cleaning starts. Call (361) 326-5060 for a free estimate with a written price before work begins.
Our Air Duct Cleaning team knows Kenmore’s housing stock because we’ve worked it for years. The mid-century ranches and split-levels here weren’t built with flex duct. They have long runs of unlined galvanized steel that corrode from the inside, especially where ductwork passes through damp crawlspaces. That changes how we approach the job, what equipment we bring, and what we check before we quote.
Why Hollis Air Duct Cleaning Is Kenmore’s Preferred Air Duct Cleaning Company
Hollis has been part of the Garrison Partners family since 2004. We operate under The Garrison Standard, which means written prices, written guarantees, and a 365-Day Done Right Promise on every job. In Kenmore, that matters because too many homeowners have watched a low teaser quote balloon once the technician saw the crawlspace.
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, 7 days a week. No voicemail loops, no callback queues.
We coordinate scheduling from our Seattle office, and crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. For filtration upgrades, we stock Aprilaire and Guardsman products suited to older forced-air systems like the ones common in Kenmore.
The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Commercial Air Duct Cleaning in Kenmore
Commercial Air Duct Cleaning in Kenmore covers office buildings, retail spaces, medical clinics, and light industrial facilities where occupancy loads and insurance requirements demand documented HVAC hygiene. We use negative-air machines from Nikro and rotary brush systems from Rotobrush to dislodge and extract debris from trunk lines and branch ducts without shutting down operations longer than necessary. A typical commercial system in Kenmore runs $800 – $2,400 depending on square footage, duct complexity, and contamination level. We provide a written scope and price before any work starts.
System Documentation for Property Managers
Kenmore commercial clients often need before-and-after photos and written reports for insurance or lease compliance. Our crew documents every stage: pre-inspection video, debris load measurements, and post-cleaning verification. This paperwork travels with the invoice, not as an add-on.
Minimizing Downtime in Mixed-Use Buildings
Many Kenmore commercial properties combine retail below and offices above, with shared mechanical rooms. We sequence our work to keep one zone operational while cleaning another, and we schedule around your hours, not ours.
Air Duct Cleaning Services in Kenmore
Air Duct Cleaning Services in Kenmore start with understanding what kind of duct system you actually have. Most homes here built before 1980 run galvanized steel trunk lines with metal branch ducts, not the flex duct common in newer Bothell or Kirkland construction. That older metal corrodes internally, flakes rust into the airstream, and develops disconnected joints where crawlspace air bypasses the filter entirely. Our residential cleaning runs $350 – $650 for a full system, with video inspection included so you see what we’re seeing before we quote.
Camera Inspection Before Agitation
We run a borescope through the trunk line first. In Kenmore’s 1960s and 1970s homes, we regularly find rust scaling, rodent debris in crawlspace runs, and separated joints that explain why certain rooms never heat evenly. Seeing the problem lets us price accurately and clean effectively.
Source Removal Under Negative Pressure
A shop-vac at the register doesn’t cut it for these systems. We seal the ductwork and use a Nikro negative-air machine to maintain suction at the source while Rotobrush agitation tools knock debris loose. HEPA filtration captures what we pull out, so it doesn’t resettle in your house.

Trusted Brands We Service in Kenmore

We confirm compatibility when you call, then bring the right gear.
Common Air Duct Cleaning Problems We See in Kenmore Homes
- Internal corrosion in 50 – 70 year old galvanized ducts. The unlined steel trunk lines in Kenmore’s mid-century homes flake rust into the airstream once the protective galvanizing wears through. That reddish dust on your registers isn’t ordinary household dirt.
- Disconnected joints in crawlspace runs. The Sammamish River corridor homes are especially prone to this. Ducts sag, separate at the seams, and pull unfiltered crawlspace air straight into the supply side. Your furnace filter never sees that contamination.
- Rodent debris in fog-damp crawlspaces. Kenmore’s wet climate and river proximity create conditions mice and rats exploit. They nest in ductwork, leave droppings and nesting material, and often die in the trunk line. We find this more often in crawlspace runs than in attic duct systems.
- Mold and mildew in uninsulated metal ducts. From October through April, Kenmore’s high outdoor humidity condenses on cold duct surfaces. Without proper insulation, that moisture drives biological growth that recirculates through the home every time the blower cycles.

FAQs About Air Duct Cleaning in Kenmore
Every 3 – 5 years for the ductwork itself, with annual filter changes and a camera inspection every other cleaning to check for internal corrosion progression. The flaking rust in these older systems accelerates debris loading compared to flex duct, and the disconnected joints we find in Kenmore crawlspaces let contamination bypass the filter entirely. Call (361) 326-5060 to schedule an inspection and we’ll tell you where your system stands.
Yes. Kenmore’s humidity from October through April drives condensation on cold metal duct surfaces, which feeds mold and mildew growth that dry-climate homes rarely see. That same moisture rusts galvanized steel from the inside out. We use HEPA-contained negative-air methods and moisture assessment as standard practice here, not optional add-ons. Call (361) 326-5060 for a free estimate.
A proper cleaning includes camera inspection of the trunk line, mechanical agitation with rotary brushes under negative pressure, register and return cleaning, and a post-cleaning video showing the results. For long runs in split-level homes, we verify airflow at distant registers before we leave. We also check for disconnected joints in crawlspace sections, which are common in this housing stock. Call (361) 326-5060 and we’ll walk through your specific layout.
Most 1970s furnaces handle MERV 8 – 11 without airflow restriction; we verify static pressure before recommending higher ratings. For homes with corrosion or rodent history, we often pair a MERV 11 pleated filter with an Aprilaire or Guardsman media cabinet that seals bypass gaps. The filter catches what the ductwork sheds. Call (361) 326-5060 and we’ll match filtration to your system’s actual capacity.
We account for access time when we quote. Properties on unpaved roads or with shop and garage systems need the same equipment but longer setup and breakdown. We schedule those jobs with buffer time built in, and we confirm drive conditions when you call so the crew brings appropriate site protection. The price is still fixed in writing before work starts. Call (361) 326-5060 to discuss your property’s access.
