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 North Lynnwood
Air duct cleaning in North Lynnwood typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few business days. If your home was built in the 2000s or later in Meadowdale or Lake Stickney, construction debris is likely still sitting in your flex branches even years after move-in.
We’ve been serving North Lynnwood homeowners since 2004, dispatching crews from our Seattle office to handle everything from new-construction cleanouts to rodent-damaged ductwork in the older subdivisions off 164th Street SW. Our Air Duct Cleaning team knows the difference between a 1978 split-level with flex duct in a vented crawlspace and a 2019 planned-community home with rigid metal trunks. That matters because the problem in your ducts depends on when your house was built, where the ductwork runs, and what the Puget Sound climate has done to it. Call us at (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is North Lynnwood’s Preferred Air Duct Cleaning Company
North Lynnwood sits in Snohomish County’s fast-growing suburban corridor, and we’ve watched the housing stock shift from 1970s split-levels to the newer planned communities near Meadowdale and Lake Stickney. Our crews know both. We arrive inside the quoted window, price the job in writing before touching anything, and leave the site clean. That’s The Garrison Standard.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
Every job carries our 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. Competitors in this trade rarely put that in writing.
We serve North Lynnwood with the same equipment commercial crews use: Rotobrush rotary brush systems, Nikro negative-air machines, and HEPA filtration from brands like Honeywell and Aprilaire. Not hardware-store gear.
Air Duct Repair in North Lynnwood
Air Duct Repair in North Lynnwood is most often needed in the 1970s – 1990s housing stock, where original flex duct in vented crawlspaces has degraded from decades of moisture, rodent activity, or simple age. A typical repair runs $200 – $500 per section, with full duct replacement in a crawlspace reaching $1,500 – $3,500 depending on access and material.
Crushed or Disconnected Flex Duct
In North Lynnwood’s older homes, flex duct gets crushed by storage items in crawlspaces or pulled loose at takeoff connections. We cut out the damaged section, install new insulated flex with proper support straps, and seal every joint with mastic. The goal is restoring airflow to the room that suddenly went cold.
Rodent-Damaged Runs
Original flex duct in the subdivisions off 164th Street SW is notorious for rodent entry. We remove contaminated ductwork, install rodent-resistant rigid metal where accessible, and seal penetrations with galvanized mesh. This is duct repair, not just cleaning, and we price it in writing before starting.
Ductwork Cleaning in North Lynnwood
Ductwork Cleaning in North Lynnwood addresses two distinct problems depending on your home’s age. In newer construction, it’s construction debris in flex branches and registers. In older homes, it’s dust compounded by moisture-driven mold and rodent contamination. A full residential system clean runs $350 – $650; commercial systems start around $800 and scale with square footage.
Source-Removal for Construction Debris
New-construction homeowners in Meadowdale and Lake Stickney often assume builder-grade ductwork is clean at handover. It isn’t. Drywall dust, sawdust, and debris sit in flex branches until a NADCA-standards source-removal clean is done. We use Rotobrush agitation under negative pressure with HEPA filtration at the air handler. Fine dust that migrated past the filter during construction doesn’t come out with a standard vacuum.
Mold and Moisture Remediation
North Lynnwood’s wet, marine climate keeps crawlspaces damp six months a year. When we find mold in ductwork, we clean with EPA-registered antimicrobial agents, then address the moisture source. Often that means recommending duct sealing to keep conditioned air from leaking into cold, moist crawl spaces where condensation forms.
Trusted Brands We Service in North Lynnwood
Our equipment roster includes Nikro negative-air machines, Honeywell filtration products, and Aprilaire media cleaners. We stock common parts and filtration media for North Lynnwood customers, so replacements don’t mean waiting on a warehouse shipment. For homes with integrated Honeywell or Aprilaire whole-house filtration, we carry the correct MERV-rated media on the truck. If your system uses Abatement Technologies HEPA equipment, our technicians are trained on proper filter change intervals and pressure-drop testing. The right tool for the duct type matters. A rotary brush system that works in rigid metal trunk lines can damage older flex duct. We match the method to the material.
Common Air Duct Cleaning Problems We See in North Lynnwood Homes
- Construction debris in new planned-community homes. Builders in Meadowdale and Lake Stickney often ran the air handler during construction without MERV-rated filtration on the return side. Drywall dust migrated past the filter and settled into supply and return ducts where a standard vacuum won’t reach it. Homeowners move in, run the system, and dust the house for months.
- Rodent nests and moisture damage in 1970s – 80s subdivisions. The original flex duct in vented crawlspaces off 164th Street SW is vulnerable to rodent entry and condensation. Technicians routinely find nests, droppings, and mold alongside household dust. Cleaning here often becomes rodent-proofing and duct-sealing work.
- Leaky ductwork wasting energy in unconditioned spaces. Long duct runs through damp crawlspaces and attics lose conditioned air through gaps at joints and seams. North Lynnwood’s cool, wet winters make this especially costly. Sealing with mastic after cleaning restores efficiency.
- Blocked registers from renovation debris. Homeowners who remodeled kitchens or bathrooms often find sawdust and drywall compound packed into branch takeoffs. The room never heats or cools right, and the homeowner blames the HVAC unit when it’s a duct obstruction.

FAQs About Air Duct Cleaning in North Lynnwood
Because builders rarely clean ductwork before handing over the keys. Drywall dust, sawdust, and construction debris sit in the flex branches and registers of Meadowdale and Lake Stickney homes, then blow into living spaces when the system runs. Our tech was called to a 2018-built home in Lake Stickney where the homeowner had been sneezing since move-in; a camera inspection showed drywall dust packed into the flex branches. We ran a Rotobrush agitation tool through each branch under negative pressure with HEPA filtration, and the dust smell was gone within a day. Call (361) 326-5060 if you’re experiencing similar symptoms.
Yes. North Lynnwood sits in the cool, wet Puget Sound lowlands where heavy fall and winter rain and persistent high humidity keep crawlspaces damp. This promotes mold and mildew growth inside ductwork and makes seal integrity critical. Cleaning here is often as much about moisture control and sealing as it is about dust removal, especially in older homes with flex duct in vented crawlspaces. Call (361) 326-5060 for an inspection.
Source removal of contaminants using agitation devices and negative-air collection, with HEPA filtration to prevent redistribution. For a typical North Lynnwood home, that means accessing all supply and return registers, cleaning branch lines with rotary brush or air-whip tools, and extracting debris at the air handler under controlled negative pressure. We provide before-and-after photos of your own ducts. Call (361) 326-5060 to schedule.
Original flex duct in vented crawlspaces is soft, warm, and easy for rodents to enter and nest in. The subdivisions off 164th Street SW have decades of this infrastructure, and the damp Puget Sound climate accelerates deterioration. We routinely find nests, droppings, and moisture-driven mold alongside dust in these homes. Cleaning becomes rodent-proofing and duct-sealing work. Call (361) 326-5060 for an inspection and written quote.
Signs include persistent dust on surfaces shortly after cleaning, a drywall-like smell when the system runs, reduced airflow at certain registers, or allergy symptoms that started after move-in. We offer video inspection for $150 – $250, which lets you see inside your own ducts. If we find construction debris, we’ll show you and quote a source-removal clean before doing any work. Call (361) 326-5060 to book.
