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 Normandy Park’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Normandy Park by showing up inside the quoted window and leaving the site clean, every single time. Homeowners here don’t want surprises, and we don’t create them. Our technicians arrive in uniform, background-checked, with the job details already confirmed by a live person who answered the phone, not a callback queue.
Normandy Park residents tell us they chose Hollis because we explain what we’re doing before we do it. The rotary brush system from Rotobrush and negative-air machines from Nikro aren’t buzzwords here; we walk you through how they work in your specific system, whether you’ve got original 1950s galvanized ductwork in a mid-century ranch off 1st Avenue or a newer setup in a custom home tucked into the woods above the Sound.
Our response time to Normandy Park is typically same-week scheduling, with dispatch coordinated from our Seattle office. We know the local terrain, the narrow wooded lots, and the access challenges that come with hillside homes. That familiarity means we arrive prepared, not guessing.
Every technician works under The Garrison Code: arrive inside the window, price in writing, complete the job by the book, leave the site clean. It’s not a slogan. It’s how we operate on every Air Duct Cleaning in Normandy Park call.
Ductwork Cleaning in Normandy Park
Ductwork Cleaning in Normandy Park addresses the accumulated debris, mold spores, and organic matter that this city’s damp climate and dense tree canopy push into residential HVAC systems year after year. The process involves sealing off individual vents, using a rotary brush system to agitate buildup from duct walls, and extracting it with negative-air pressure so nothing resettles in your home. For a typical Normandy Park single-family home, full ductwork cleaning runs $350 – $550, with larger homes or systems with substantial buildup ranging up to $650.
When Your System Needs Attention
Normandy Park homeowners usually call us after wet winters when musty odors become unmistakable, or when they’ve renovated a mid-century home and disturbed decades of settled debris. If you’re running your HVAC more frequently just to move air that still feels stale, that’s a sign your ductwork is working harder than it should for diminishing returns.
What the Process Looks Like
We start with a written price before touching anything. Then we seal your vents, run the Rotobrush rotary system through each branch, and capture dislodged material with Nikro negative-air equipment. For homes under the heaviest tree cover, we also clear exterior intakes of moss and organic buildup that would otherwise recontaminate the system within months.
Air Duct Inspection in Normandy Park
Air Duct Inspection in Normandy Park gives homeowners a clear picture of what’s happening inside walls and crawl spaces they can’t see into, using video cameras to document corrosion, debris buildup, mold growth, or disconnected segments. Given the city’s salt-laden marine air and the age of much of its housing stock, we find that inspections often reveal accelerated corrosion in older metal ducts or organic blockage in exterior intakes that owners didn’t know existed. A standalone video inspection runs $150 – $250 in Normandy Park; if you proceed with cleaning, we typically apply that fee toward the full service.
What the Camera Reveals
We feed a high-resolution camera through your supply and return lines, recording footage you can review with us in real time. In Normandy Park homes near the water, we regularly spot salt corrosion on galvanized steel that weakens duct walls and creates leaks. Under the dense canopy off Normandy Road and around the golf course, we often find moss spores and fine organic debris coating duct interiors.
When to Schedule an Inspection
Book an inspection before buying a mid-century home in Normandy Park, after any water intrusion event, or if you’re experiencing persistent odors or airflow issues that filter changes haven’t resolved. The footage gives you facts, not guesses, and a written report you can use for insurance documentation or future maintenance planning.
Trusted Brands We Service in Normandy Park
We carry and install filtration and cleaning equipment from Aprilaire, Abatement Technologies, and Guardsman, with parts stocked for fast turnaround on Normandy Park jobs. Aprilaire media air cleaners handle the high particulate load that our marine climate produces, while Abatement Technologies HEPA filtration integrates with our Nikro negative-air machines to capture mold spores and fine debris at the source. Guardsman products round out our lineup for homeowners who want added protection between professional cleanings. We don’t push brands you don’t need. We match the equipment to your specific system, your home’s age, and what the video inspection actually shows.
Common Air Duct Cleaning Problems We See in Normandy Park Homes
- Moss and organic debris in exterior intakes. Homes nestled under Normandy Park’s dense cedar and fir canopy, especially those off Marine View Drive and in the wooded sections above Three Tree Point, regularly pull moss spores and decaying leaf matter into fresh-air intakes. This buildup restricts airflow and introduces musty odors that circulate through every room.
- Corrosion in original galvanized ductwork. The salt-laden moisture from Puget Sound accelerates rust and weakening in the galvanized steel ducts common to Normandy Park’s 1940s – 1970s housing stock. Corroded segments leak conditioned air into crawl spaces and draw in unfiltered attic or basement air.
- Mold growth from stagnant humidity. Normandy Park’s mild, wet winters and cool summers mean HVAC systems cycle less frequently than in harsher climates. That intermittent operation lets humidity sit in ductwork, creating ideal conditions for mold and mildew colonization between heating and cooling seasons.
- Disconnected or collapsed flexible duct segments. In homes where prior owners attempted DIY repairs or hired cut-rate installers, we find flexible ductwork pulled apart at joints or crushed in tight crawl spaces. These disconnections dump heated or cooled air into unused spaces and starve rooms of airflow.
Pricing for Air Duct Cleaning in Normandy Park, WA
A typical full residential air duct cleaning in Normandy Park runs $350 – $550 for homes up to about 2,500 square feet, with larger homes or systems requiring substantial remediation reaching $650. Commercial duct cleaning starts around $800 and scales with system complexity. Here’s how pricing breaks down:
- Full residential system cleaning: $350 – $650
- Video inspection (standalone): $150 – $250
- Supply duct cleaning only: $200 – $350
- Return duct cleaning only: $200 – $350
- Dryer vent cleaning (add-on): $125 – $200
What moves the price? System accessibility matters: crawl spaces with limited clearance take longer. The degree of contamination matters: heavy mold or moss remediation requires additional HEPA containment and disposal steps. Home size and vent count matter, though we price by the system, not by the vent, so you’re not nickel-and-dimed for every register. We also handle Dryer Vent Cleaning in Normandy Park and Duct Sealing in Normandy Park if your inspection reveals those needs.
Every price is written down before we start. No estimates that balloon once we’re inside. If the scope changes, we stop and get your approval in writing. Call (361) 326-5060 for your free estimate.
