Why Hollis Air Duct Cleaning Is Stanwood’s Preferred Air Duct Cleaning Company

We’ve been cleaning ducts since 2004, and the Garrison Partners family built Hollis on a simple standard: show up inside the window, price it in writing, and stand behind the work for a full year. That discipline matters more in Stanwood than it might in a drier climate, because duct cleaning here isn’t just dust removal. It’s moisture remediation, mold prevention, and knowing how older mill-town construction changes the job.

Our technicians are background-checked, uniformed, and trained on Rotobrush rotary brush systems and Nikro negative-air equipment. They know Stanwood’s housing stock, the flex duct runs in post-war crawlspaces, and the newer sealed systems going into subdivisions near 88th Avenue Northwest. When we quote a job, the price is written down before we touch anything. No surprises at the door.

Phones get answered by a live person, 24 hours a day, seven days a week. No voicemail loops, no callback queues on a Monday morning. That responsiveness matters when you’re dealing with musty air or post-flooding concerns and want a straight answer about whether duct cleaning is the right move.

Every job carries our 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit. We put that in writing on every invoice.

Air Duct Inspection in Stanwood

Air Duct Inspection in Stanwood typically starts with a homeowner noticing uneven heating, a persistent musty smell, or higher-than-expected energy bills after a wet winter. Our inspection runs a video camera through the supply and return lines, checks the plenum and trunk connections, and documents what we’re seeing so you can decide whether cleaning, sealing, or repair makes sense. In Stanwood, we often find moisture staining in flex ducts near the Stillaguamish flood zone, or debris buildup where agricultural dust from the valley has settled into older galvanized trunk lines. A standard residential inspection in Stanwood runs $89 – $149, and we’ll apply that toward your cleaning if you move forward.

What the Camera Reveals

The video inspection shows you exactly what’s inside your ducts: dust accumulation, mold growth, disconnected joints, or evidence of pests. In Stanwood’s older homes near downtown, we regularly find original ductwork with deteriorating fiberglass lining that’s trapping moisture against the metal. You’ll see it on the monitor, and we’ll explain what it means for your air quality without pushing unnecessary work.

When to Schedule

Book an inspection if you’ve noticed odors when the system cycles, if your home flooded or had significant moisture intrusion, or if it’s been more than five years since any ductwork was evaluated. After the 2022 and 2023 winter flood events along the lower Stillaguamish, we saw a spike in calls from Stanwood homes where crawlspace ducts had taken on silt that standard vacuuming couldn’t reach.

Residential Air Duct Cleaning in Stanwood

Residential Air Duct Cleaning in Stanwood means pulling debris from the entire HVAC pathway: supply ducts, return ducts, registers, grilles, and the air handler cabinet. We use a Rotobrush rotary brush system to agitate buildup off duct walls, coupled with negative-air containment from Nikro equipment so nothing escapes into your living space. For a typical Stanwood single-family home between 1,500 and 2,500 square feet, residential cleaning runs $349 – $549. Larger homes, multiple systems, or heavy contamination from flooding can push that toward $650 – $850.

Older Homes Need a Different Approach

Stanwood’s early-1900s through mid-century housing often has retrofitted flex duct in attics and crawlspaces, with joints sealed by tape that’s failing after decades of moisture exposure. We adjust our brush selection and vacuum strength to avoid damaging fragile connections, and we flag any duct sealing needs we spot. If your home is near the river bottoms off Pioneer Highway, we’ll specifically check for silt infiltration that standard cleaning might miss.

What Happens During the Visit

A two-person crew arrives in a marked van, lays protective covering, and walks you through the written price before starting. The job takes two to four hours for most Stanwood homes. We photograph the before condition, clean every accessible component, and show you after photos. The site gets cleaned before we leave. That’s The Garrison Standard, and it’s how we’ve operated since 2004.

Trusted Brands We Service in Stanwood

Hollis crews work with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we install filtration upgrades using Honeywell, Aprilaire, and Guardsman products when a Stanwood home needs better particle capture after cleaning. We don’t show up with shop-vacs and extension poles. The rotary brush systems we deploy are the same units commercial crews use in hospitals and schools, and the negative-air machines create sealed containment so your house doesn’t get dirtier during the cleaning. If your system needs a filtration upgrade, we stock the common sizes and configurations for residential HVAC units found in Snohomish County, which means no waiting on special orders from Seattle distributors.

Common Air Duct Cleaning Problems We See in Stanwood Homes

• Moisture and mold in crawlspace flex runs. Stanwood’s high water table and winter flooding along the Stillaguamish mean ducts in crawlspaces often sit in damp conditions. We find mold staining in flex duct insulation that’s been wet multiple seasons, and the rotary brush system with HEPA containment is the only reliable way to remove it without spreading spores through the house.
• Agricultural dust and pollen infiltration. The Skagit and Stillaguamish valleys produce significant agricultural particulate, especially during planting and harvest seasons. Older homes with leaky return pathways pull this dust directly into the duct system, where it accumulates on blower wheels and evaporator coils.
• Disconnected joints in post-war tract housing. Homes built in the 1950s through 1970s near 272nd Street and Camano Drive often have original ductwork with failed tape seals. Conditioned air escapes into attics and crawlspaces, and unconditioned air gets pulled in, carrying insulation fibers and rodent debris.
• Silt deposits after flood events. Properties near the river bottoms and sloughs can take on fine silt when groundwater rises. This material settles in low points of duct runs and standard household vacuums can’t extract it. Our negative-air method pulls it out completely, and we’ll recommend Duct Sealing in Stanwood if the entry points need to be closed.
