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.
Fast, Reliable Air Duct Cleaning Across Sultan
Sultan homeowners deal with a problem most duct cleaning companies outside the Skykomish River valley don’t understand: your ducts are pulling in wildfire smoke, wood stove ash, and heavy pollen that standard cleaning barely touches. A full residential air duct cleaning in Sultan typically runs $350 – $650 for a single-system home, and our Air Duct Cleaning crew dispatches from our Seattle office with crews already working the Highway 2 corridor. Call (361) 326-5060 for a written estimate before anyone sets foot in your home.
We’ve cleaned ducts in the older ranches near Sultan Basin Road and the manufactured homes off First Street. We know which houses have the original rigid metal ductwork with gaps at the boots, and which ones pull fresh air through an intake that acts like a chimney when the timber burns. That local knowledge changes how we approach the job.
Why Hollis Air Duct Cleaning Is Sultan’s Preferred Air Duct Cleaning Company
Roy Castellanos has led Hollis Air Duct Cleaning since 2004, building the operation under The Garrison Standard: written prices, written guarantees, and technicians who arrive inside the quoted window. Our 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.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule. When you call (361) 326-5060, you speak to someone who can book your appointment and confirm your written price.
Every technician is background-checked and uniformed. You know who’s walking into your home before they arrive. We price in writing before any work starts, and that number does not move at the door. Our equipment includes Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use, explained in plain terms on every job.
Air Duct Inspection in Sultan
Air Duct Inspection in Sultan starts with understanding what the Skykomish River valley does to your system. We use a video inspection camera to document the condition inside your supply and return lines, the blower compartment, and the plenum. For Sultan homes, we’re specifically looking for gray ash film from wildfire smoke, mold from winter humidity, and loose joints in original metal ductwork that leak conditioned air into your crawlspace. A typical inspection runs $150 – $250, and we apply that fee toward your cleaning if you move forward.
What We Document on Camera
Our video inspection records every foot of accessible ductwork. You’ll see the buildup on your own screen: pollen matting, ash residue, or crushed flex sections that need repair. We save the footage and review it with you before quoting any work.
When Sultan Homeowners Need an Inspection First
If you’ve noticed uneven heating, a persistent burnt smell when the furnace kicks on, or higher energy bills after a smoke event, start with an inspection. Many Sultan residents call after a heavy wildfire season when filters clog faster than normal. The camera shows whether cleaning will solve the problem or if you also need Duct Sealing in Sultan to stop outside air from pulling in through gaps.
Residential Air Duct Cleaning in Sultan
Residential Air Duct Cleaning in Sultan requires equipment and methods matched to local conditions. We clean the full system: supply ducts, return ducts, registers, grilles, blower motor, and evaporator coil if accessible. Our rotary brush system from Rotobrush loosens debris while a Nikro negative-air machine pulls it out under controlled suction, so nothing blows back into your living space. A typical single-system home in Sultan runs $350 – $650; larger homes or systems with heavy ash buildup may reach $750 – $950.
Wood Stove Ash and Wildfire Smoke Removal
Standard duct cleaning doesn’t always address the fine particulate that wood stoves and wildfires leave behind. We use HEPA-filtered collection and multiple agitation passes on returns that show ash film. After a nearby burn, we’ve found gray residue coating blower compartments even in homes with decent filters.
Older Ductwork That Needs Gentle Handling
Much of Sultan’s housing stock dates to before 1980. Original rigid metal ducts often have unsealed boots and loose joints. Our technicians inspect these connections before applying rotary brushes, and we’ll show you where Duct Sealing in Sultan would improve efficiency after the cleaning is done.
Trusted Brands We Service in Sultan
Our equipment roster includes professional-grade systems from Rotobrush and Nikro, plus filtration products from Honeywell, Aprilaire, and Guardsman. We don’t show up with hardware-store vacuums and a brush on a drill. For Sultan homeowners, this means we can source replacement filters, upgraded media, and sealing materials without waiting on regional distributors. If your system needs a filtration upgrade after a heavy smoke season, we stock the components and install them during the same visit. Our technicians carry Guardsman-treated filters rated for fine particulate, the kind that actually catches ash and pollen instead of letting it recirculate.
Common Air Duct Cleaning Problems We See in Sultan Homes
- Wildfire smoke infiltration through fresh-air intakes. Many Sultan homes have outdoor air intakes that pull directly from outside. During smoke events, these act like chimneys, coating return ducts with fine ash that standard filters miss.
- Mold growth in uninsulated crawlspace flex duct. Heavy winter rain and occasional flooding along the Skykomish drive humidity into crawlspaces. Uninsulated flex duct sweats, and mold follows. We find this routinely in homes near the river and in low-lying areas off Sultan Basin Road.
- Crushed or patched flex duct reducing airflow. Older manufactured homes and ranches often have flex runs that have been stepped on, rerouted, or patched with tape that fails. We document these during inspection and can coordinate repair before sealing the system.
- Pollen matting from spring forest and grass seed fields. Sultan’s surrounding timber and agricultural land produce intense pollen loads. We see green-yellow matting in returns every May and June, especially in homes that run window units or keep windows open during shoulder seasons.
Pricing for Air Duct Cleaning in Sultan, WA
We give honest whole-system pricing, not per-vent teaser rates that balloon at the door. A typical residential duct cleaning in Sultan runs $350 – $650 for a single HVAC system covering up to 15 vents. Larger homes, heavy ash or mold buildup, or additional systems add to that range. Most two-system homes fall between $650 – $950. Commercial properties along Highway 2 and in the Sultan business district typically start at $800 and scale with square footage and access complexity.
What moves the number: the number of systems, accessibility of ductwork (crawlspace work takes longer), severity of buildup, and whether we find damage that needs repair before sealing. We also offer Dryer Vent Cleaning in Sultan as an add-on, typically $120 – $180 when bundled with duct cleaning.
Every price is written down before work starts. No surprises, no upsells, no “we found something extra” once the van is in your driveway. Call (361) 326-5060 for a free estimate.
