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 Kent
Air duct cleaning in Kent typically runs $350-$650 for a full residential system and $800-$2,400 for commercial properties, with most jobs scheduled within a few business days. Our crews serve Kent from our Seattle dispatch office, and we’re familiar with the specific challenges that come with homes in the Green River Valley basin. Call (323) 918-4345 for a free written estimate before any work starts.
We’ve worked in Kent long enough to know the difference between a routine cleaning and a system that’s been compromised by the valley’s persistent moisture. East Hill ramblers, the industrial corridor near West Valley Highway, newer builds around Lake Meridian - each area presents its own duct conditions, and we adjust our approach accordingly. Our technicians arrive in uniform with shoe covers and drop cloths, and we use quieter Rotobrush and Nikro equipment when there’s a toddler napping or a skittish dog in the next room.
Why Morton’s Air Duct Cleaning Is Kent’s Preferred Air Duct Cleaning Company
Kent homeowners call us back because we treat the house like it’s our own. Our Air Duct Cleaning team has built a local reputation on showing up on time, explaining exactly what we’ll do before we touch anything, and leaving a photo of the clean-up behind. We’re part of the Cedarwell family, but we’re independently operated - not a call center, not a franchise script.
Our response time to Kent is typically a few business days for standard scheduling, and we coordinate dispatch from our Seattle office to keep routes efficient. What matters more than speed here is thoroughness: we know that East Hill crawlspaces stay damp well into June, that original flex duct from the 1980s and 90s degrades faster here than in drier upland neighborhoods, and that industrial particulates from the Kent Valley corridor find their way into duct systems through compromised connections. That local knowledge means we catch problems that out-of-area crews miss.
Every visit carries our 365-Day Done Right Promise, backed by the Cedarwell Care Promise: written price upfront, shoe covers and drop cloths on every job, background-checked technicians, and a photo of your clean-up before we leave. No exceptions.
Residential Air Duct Cleaning in Kent
Residential Air Duct Cleaning in Kent addresses the full supply and return network in single-family homes, townhouses, and condos, from the main trunk lines to each register. A typical Kent home runs $350-$650 for a complete system cleaning, with larger homes or systems requiring video inspection and remediation work falling toward the higher end. We focus on the specific conditions that affect Kent residences: persistent valley humidity, original fiberglass-lined flex duct in East Hill crawlspaces, and particulate infiltration from separated duct connections.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back. In Kent, we often find return ducts pulling humid, particle-laden air through gaps in the building envelope, while supply ducts in crawlspaces have collapsed liners or mold growth from months of damp conditions. We clean both sides of the system and document any damage we find.
Full System Cleaning with Video Inspection
Our Nikro video inspection equipment lets us show you exactly what’s inside your ducts before we start and what we’ve removed when we’re done. For Kent homes with post-storm concerns or persistent musty odors, this visual documentation is often what an insurer needs to approve remediation work.
Commercial Air Duct Cleaning in Kent
Commercial Air Duct Cleaning in Kent serves the warehouses, light manufacturing facilities, retail spaces, and office buildings that line the Kent Valley industrial corridor and dot the city’s commercial zones. Typical commercial jobs range from $800 for smaller retail systems to $2,400 or more for larger warehouse HVAC networks with extensive duct runs. We schedule around your operations, and our crews understand that downtime costs money - so we work efficiently without cutting corners.
Industrial Dust and Particulate Removal
Kent’s position as a freight and manufacturing hub means commercial ducts here accumulate finer industrial particulates than systems in purely residential communities. Our Rotobrush and Abatement Technologies equipment is sized for commercial ductwork, with enough power to dislodge built-up debris without damaging the system.
Post-Construction and Tenant Turnover Cleaning
New tenants deserve air that doesn’t smell like the last occupant’s operations. We clean between leases and after construction, with written documentation of the scope for property managers who need records for their files.
Trusted Brands We Service in Kent
We clean and maintain systems using professional-grade equipment from Rotobrush, Nikro, Honeywell, Aprilaire, and Abatement Technologies - not rental-shop vacuums with a brush taped to the hose. For Kent customers, this means we can source replacement parts and compatible components without the delays that come from ordering unfamiliar gear. Our technicians train on each manufacturer’s equipment specifications, so whether your system uses Honeywell media filters or Aprilaire humidifier components, we know how to work with it without voiding warranties or creating compatibility issues.
Common Air Duct Cleaning Problems We See in Kent Homes
- Mold inside fiberglass-lined flex duct. The Green River Valley traps marine moisture well into spring and early summer, and East Hill crawlspaces stay damp enough that mold colonization inside original supply ducts is a recurring issue here, not an occasional one. Cleaning alone won’t fix this; the liner must be replaced.
- Separated or sagged crawlspace connections. Decades of humidity and gravity pull duct connections apart in East Hill tract homes, creating gaps that pull in humid soil air and fine particulates from the Kent Valley industrial corridor below. We find this combination of contamination sources in no other nearby city.
- Post-storm water intrusion with inadequate documentation. After flooding, some crews clean wet ducts without drying or replacing compromised liner, which spreads mold spores through the system. Others skip moisture readings and photos, leaving homeowners to fight denied insurance claims alone.
- Industrial particulate infiltration in homes near the freight corridor. Diesel exhaust and manufacturing dust carry uphill from the valley floor, entering duct systems through compromised connections and aging building envelopes. Standard cleaning removes the buildup; inspection finds and seals the entry points.
Pricing for Air Duct Cleaning in Kent, WA
A typical residential full-system cleaning in Kent runs $350-$650, depending on the number of supply and return vents, whether the system includes a main trunk and multiple branches, and the accessibility of the ductwork. Commercial systems start around $800 and scale based on square footage and system complexity. Video inspection adds $150-$250 when needed for documentation or insurance claims.
What affects your specific price: the age and condition of your duct material (original fiberglass flex duct in East Hill homes often needs more careful handling), whether we find separated connections that need resealing, and any post-storm or post-flood remediation that requires documentation for insurance. We give you one flat price per system, agreed in writing before we start. No per-vent add-ons, no surprise charges when the van pulls up. Call (323) 918-4345 for your free estimate.
We Also Serve Cities Near Kent
Our crews regularly work in Kent and the surrounding communities, including Renton to the north, Auburn to the south, Federal Way to the west, and Maple Valley to the east. Each area has its own duct conditions - Maple Valley’s elevation means drier crawlspaces, while Federal Way’s mix of coastal and inland exposure creates different humidity patterns - and we adjust our inspection and cleaning approach accordingly.

FAQs About Air Duct Cleaning in Kent
It depends on the duct material, the duration of water exposure, and whether the inner liner has collapsed or mold has colonized the fiberglass. Metal ductwork with no insulation damage can often be cleaned, dried, and resealed; fiberglass-lined flex duct that has been wet for more than 24-48 hours typically needs replacement because mold penetrates the porous liner and cleaning won’t reach it. We determine this with moisture meters, video inspection, and negative pressure testing, then give you a written scope with photos before any work starts. Call (323) 918-4345 to schedule an assessment.
We provide moisture readings with calibrated meters, timestamped video inspection footage, photographs of contamination and damage, and a written scope of work with line-item pricing. This documentation package is designed to meet standard adjuster requirements without a second visit from another contractor. A homeowner on Kent’s East Hill used our documentation to get full coverage for a compromised supply run after a winter storm - insurer approved it on first review. We include this documentation on every post-storm assessment.
Kent’s Green River Valley basin traps marine moisture well into spring and early summer, so East Hill crawlspace supply ducts stay damp longer than ducts in upland Covington or Maple Valley - which is why mold colonization inside supply ducts is a recurring service-call driver here, not an occasional one. The combination of persistent humidity and original fiberglass-lined flex duct from the 1970s-1990s build-out creates conditions that simply don’t occur as consistently at higher elevations. If you live on East Hill and smell musty air when the system kicks on, this is likely why.
We use professional Rotobrush and Nikro HEPA-filtered vacuum systems with powered brush agitation, plus Nikro video inspection cameras and Abatement Technologies containment equipment. Our methods follow NADCA-recommended practices for source removal: negative pressure containment, mechanical agitation to dislodge debris, and HEPA filtration to prevent cross-contamination. We don’t use chemical biocides as a substitute for mechanical cleaning, and we’ll show you the before-and-after photos to prove the work.
Separated or sagged supply-duct connections in your crawlspace are pulling in humid soil air and fine particulates from the Kent Valley industrial corridor, a combination unique to homes positioned above this freight and manufacturing zone. The smell intensifies after rain because soil moisture increases and atmospheric pressure changes draw more crawlspace air into the system. We find this regularly in East Hill tract homes with original flex duct. Our crew will inspect the connections with a camera, seal or replace the compromised sections, and verify with negative pressure testing that we’ve stopped the infiltration. Call (323) 918-4345 to schedule.
