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 Shoreline
Air duct cleaning in Shoreline 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 Shoreline neighborhoods directly, including Richmond Highlands, Richmond Beach, and Ridgecrest. If your registers are pushing musty air or your energy bills have climbed without explanation, call (361) 326-5060 for a free written estimate.
Shoreline’s wet climate and post-war housing stock create duct problems you won’t find in drier markets. Our Air Duct Cleaning team has worked the crawlspaces here long enough to know what to look for before we open the first register.
Why Hollis Air Duct Cleaning Is Shoreline’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family. That track record predates most competitors you’ll find in Shoreline today. Our crews know the difference between a 1958 Richmond Highlands ranch with original metal ductwork and a 2005 Ridgecrest townhome with flex duct runs, and we price accordingly before any work starts.
Every Hollis job in Shoreline is covered by our 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit. The price is written down before we touch your system, and it does not move at the door.
Our technicians are background-checked and uniformed. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
We coordinate dispatch and scheduling from our Seattle office, and crews serve Shoreline locally. That means we’re not routing trucks from Tacoma or Bellevue and hoping they hit the window.
Commercial Air Duct Cleaning in Shoreline
Commercial Air Duct Cleaning in Shoreline covers office buildings, retail spaces, medical clinics, and multi-family properties where occupancy codes and insurance requirements demand documented HVAC hygiene. We use Nikro negative-air machines to establish contained suction throughout the duct network, then run rotary agitation tools to dislodge buildup without contaminating occupied spaces. A typical commercial job in Shoreline runs $800 – $2,400 depending on square footage, system accessibility, and whether microbial treatment is needed after cleaning.
Office and Retail Systems
Shoreline’s commercial corridors along Aurora Avenue and Ballinger Way see heavy traffic and outdoor particulate loading. We schedule after-hours or weekend work to avoid disrupting business, and we provide written documentation of completion for property managers and insurers.
Multi-Family and HOA Properties
Shared return plenums in Shoreline’s older apartment buildings can distribute contaminants between units. We isolate each line before cleaning and photograph interior conditions for the property file.
Air Duct Cleaning Services in Shoreline
Air Duct Cleaning Services in Shoreline address the specific failure modes this climate creates. Our residential process starts with a video inspection, then we set up negative-air containment, run rotary brushes through supply and return ducts, clean the blower motor and air handler, and apply microbial treatment where moisture has promoted mold growth. A typical full system cleaning in Shoreline runs $350 – $650, with dryer vent cleaning often bundled at $120 – $180.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms; returns pull it back. In Shoreline’s damp crawlspaces, return ducts often pull in unfiltered soil air through disconnected joints. We clean both sides and seal accessible leaks we find.
Video Inspection and Documentation
We run a camera before and after so you see what was in there. In Shoreline, we regularly find standing water in low duct runs, pest debris, and mold staining that homeowners didn’t know existed until they saw it on screen.

Trusted Brands We Service in Shoreline
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use, not hardware-store gear. We stock common replacement parts and media locally, so Shoreline customers aren’t waiting on shipping if a filter upgrade or UV light install makes sense while we’re already in the system. Our technicians explain what each piece of equipment does and why we’re using it on your specific job, in plain terms, before we start.
Common Air Duct Cleaning Problems We See in Shoreline Homes
- Disconnected crawlspace joints in Richmond Highlands ranches. Original metal ductwork in Shoreline’s post-war neighborhoods often separates at seams in unsealed crawlspaces, pulling damp soil air and rodent debris directly into the supply stream. We find this on camera and seal it during cleaning.
- Flex duct sagging in damp crawlspaces. Shoreline’s newer homes and townhomes use flex duct that pools condensation and loses airflow where it droops between joists. Cleaning alone won’t fix the sag; we flag it so you can address the support issue.
- Mold and mildew rebound in high-humidity seasons. From October through May, Shoreline’s persistent moisture lets microbial growth return fast if a cleaning skips the blower motor, air handler, and antimicrobial treatment. We treat the full path, not just the visible duct.
- Outbuilding and detached garage systems. Shoreline properties with shop buildings or ADUs often have duct runs that go years without service. Longer drives and rural dust loading mean these systems need attention on a shorter interval than the main house.
Pricing for Air Duct Cleaning in Shoreline, WA
Most full residential system cleanings in Shoreline fall between $350 and $650. Commercial jobs typically run $800 – $2,400. Dryer vent cleaning adds $120 – $180. What moves the number: system size, duct material (metal vs. flex), accessibility (crawlspace height, attic hatch location), whether we find disconnected joints that need sealing, and whether microbial treatment is indicated after inspection.

FAQs About Air Duct Cleaning in Shoreline
A typical full residential system cleaning in Shoreline runs $350 – $650, with commercial jobs at $800 – $2,400 and dryer vent cleaning at $120 – $180. The exact figure depends on system size, duct material, and whether we find leaks or microbial growth that need additional work. Call (361) 326-5060 for a free written estimate.
We use Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are professional-grade tools, not retail gear, and our technicians explain what each one does on your specific job before starting.
Low teaser quotes usually come with per-vent pricing that balloons once the technician is inside, or they cover register-level vacuuming only and skip the crawlspace joints, blower motor, and air handler where Shoreline’s real problems live. We price the full system in writing before we start. No per-vent structure. No surprises at the door.
We run video inspection before and after, and we walk you through the footage. For Shoreline jobs, we also photograph crawlspace conditions and any sealed joints. You see what came out, what the ducts look like now, and what we found that you couldn’t see from the living room.
With Shoreline’s wet climate and unsealed crawlspaces, most homes benefit from cleaning every three to five years. Properties on unpaved roads, with wood heat, or with outbuilding systems may need shorter intervals due to heavier dust and pollen loading. If you smell musty air at the registers or see dust puffing out when the system kicks on, it’s time to call.
