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 Des Moines
Air duct cleaning in Des Moines, WA typically costs $380-$620 for a complete residential system and is scheduled by appointment with a written price confirmed before any work begins. We’re Kestrel Air Duct Cleaning, and our crews serve Des Moines from our Seattle office, carrying the Kingswell Guarantee to every job in this city.
Des Moines sits in a unique spot, directly beneath the flight paths of Seattle-Tacoma International Airport. Thousands of local homes received modified HVAC systems through the Port of Seattle’s Sound Insulation Program, and those retrofitted ducts, now 20-30 years old, were engineered for noise reduction, not clean airflow. Our Air Duct Cleaning team knows what to look for in these systems. We find blind duct stubs, disconnected returns, and decades of accumulated jet-exhaust particulate that standard cleaning misses. If your home is on the bluffs above Puget Sound or tucked into the hillside neighborhoods near Marine View Drive, you’ve probably got the long crawl-space duct runs and original 1960s-1980s materials that make professional inspection essential before any cleaning begins. Call us at (469) 972-3151 for a free estimate.
Why Kestrel Air Duct Cleaning Is Des Moines’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Des Moines by showing up in the window we promised and leaving the written guarantee behind. Dale Whitmore leads our operation under the Kingswell Guarantee, and that means four non-negotiable standards on every visit: a written price before work starts, a defined arrival window, a clean job site, and a written promise with a free return visit if anything fails within the guarantee period.
Our technicians are background-checked, uniformed, and trained on the equipment that actually works: Rotobrush rotary brush systems for dislodging debris at the duct wall, Nikro negative-pressure units for pulling contaminants out of the system, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. No box-store shop vacs. No guesswork.
Calls are answered by a live person, 24/7. Not a voicemail queue. Not an automated system. A real conversation, any time of day.
We understand Des Moines’s housing stock because we’ve worked it. The split-levels off South 216th Street. The hillside ranches with Pacific Sound views. The homes that participated in the Sound Insulation Program and now have duct configurations you won’t find in Federal Way or Kent. That local knowledge means we arrive prepared for what your system actually contains, not what a generic checklist assumes.
Ductwork Cleaning in Des Moines
Ductwork Cleaning in Des Moines requires more than running a brush through visible vents, because many homes here harbor blind duct stubs and re-routed returns left behind by Sound Insulation Program retrofits that standard cleaning never touches. A typical full-system ductwork cleaning in Des Moines runs $380-$620, with larger homes or systems requiring remediation of mold-damaged flex duct in crawl spaces running toward the higher end.
Our process starts with a camera inspection to map your actual duct layout, not the original blueprint. We use rotary brush agitation, which means a spinning brush head dislodges debris caked on duct walls, followed by negative-air extraction, which pulls that loosened material out of your home entirely under controlled suction. In Des Moines’s damp climate, we frequently find mold colonization inside flex-duct sections under hillside homes where ground moisture persists year-round. Surface brushing alone won’t remove it. We target those areas with extended agitation cycles and verify clearance with a follow-up camera pass.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Des Moines homes with Sound Insulation retrofits, we’ve found supply runs that were re-routed or partially blocked to reduce noise infiltration, cutting airflow to specific rooms by 30% or more. We map each supply branch, remove registers, and clean the full run to the plenum.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit for reconditioning. This is where Des Moines’s unique problems hide. The disconnected return-air stubs we find in Sound Insulation Program homes aren’t connected to active airflow, so they sit stagnant, collecting dust and particulate for decades. Our camera inspection identifies these dead legs before cleaning begins.
Air Duct Inspection in Des Moines
Air Duct Inspection in Des Moines is the step most homeowners skip and almost always wish they hadn’t, because the blind stubs and crushed runs common in this city’s older housing stock are invisible from every vent opening. A standalone inspection runs $180-$280, or it’s included at no additional charge when bundled with a full cleaning service.
We feed a high-resolution camera through your duct system, recording every junction, transition, and potential failure point. In Des Moines, we’re specifically looking for three things: disconnected return stubs from Sound Insulation retrofits, moisture-damaged flex duct in crawl spaces, and crushed or sagging runs from original 1960s-1980s installations. The camera doesn’t guess. It shows exactly what’s there.
Video Documentation
You see what we see. The video file is yours to keep, and we timestamp every finding. If we locate a blind stub or crushed run, we mark the footage, explain your options, and give you a written price for any repair before proceeding.
System Performance Assessment
We measure static pressure and airflow at multiple points to identify restrictions that cleaning alone won’t fix. A crushed duct run in a Des Moines crawl space might be spotless after agitation but still choke your system. The inspection tells you the difference.
Trusted Brands We Service in Des Moines
Des Moines homes that went through the Sound Insulation Program often carry Honeywell, Aprilaire, or Guardsman filtration and indoor-air-quality products installed during retrofit work. We stock replacement media and components for these systems locally, so Des Moines customers aren’t waiting on shipped parts. Our technicians also service the HVAC brands commonly found in these retrofitted homes, including original equipment that may now be 25-30 years old. If your system needs filtration upgrades between cleanings, we carry the full Honeywell, Aprilaire, and Guardsman lines and can install them during the same visit.
Common Air Duct Cleaning Problems We See in Des Moines Homes
- Blind return-air stubs from Sound Insulation Program retrofits. These disconnected duct segments were sealed off to reduce noise infiltration but weren’t removed, creating dead legs that accumulate dust and jet-exhaust particulate for decades. A standard vent cleaning never touches them because they’re not connected to active airflow.
- Moisture-saturated flex duct in hillside crawl spaces. Des Moines’s 38+ inches of annual rainfall, concentrated October through March, keeps ground moisture high year-round under homes on the bluffs. Flex-duct sections absorb this moisture and promote mold colonization that requires extended agitation and HEPA-contained removal.
- Crushed or disconnected original duct runs. The 1960s-1980s split-level and ranch homes dominating Des Moines’s housing stock used thinner-gauge materials that sag, crush, or separate at joints over time. Homeowners notice weak airflow to certain rooms but rarely connect it to duct damage hidden in crawl spaces or behind walls.
- Jet-exhaust particulate accumulation. Des Moines’s position directly under Sea-Tac approach and departure corridors means fine particulate from aircraft engines settles on homes and enters ventilation systems. This material is distinct from ordinary household dust, heavier in carbon and metal oxides, and more resistant to standard removal methods.
Pricing for Air Duct Cleaning in Des Moines, WA
Most complete residential ductwork cleaning jobs in Des Moines run between $380 and $620. Homes with straightforward layouts, accessible crawl spaces, and no remediation needs typically fall in the $380-$480 range. Larger homes, systems with blind stubs requiring camera mapping and resealing, or flex-duct sections needing mold remediation push toward $520-$620. Commercial systems are priced per system and square footage after on-site assessment.
What affects your specific price: the number of supply and return vents, crawl-space accessibility, whether your home has Sound Insulation Program retrofits requiring additional inspection time, and the condition of flex-duct sections. We give you one flat price per system, agreed in writing, before a single vent is touched. No per-vent pricing. No door-step revisions. No bait-and-switch.

FAQs About Air Duct Cleaning in Des Moines
Des Moines homes need more frequent cleaning because of the combination of Sound Insulation Program retrofits that created blind duct stubs and the city’s position directly under Sea-Tac flight corridors, which deposits jet-exhaust particulate at higher rates than neighboring cities. The marine climate’s persistent humidity then binds this material to duct walls and promotes mold growth in crawl-space flex duct. Call (469) 972-3151 for a free estimate to assess your specific system.
The Port of Seattle’s Sound Insulation Program was a noise-mitigation effort that modified HVAC systems in thousands of Des Moines homes, often re-routing or disconnecting return-air intakes to reduce noise infiltration from overhead aircraft. These retrofits left blind duct stubs and partially blocked plenums that trap debris indefinitely because they’re not connected to active airflow, so standard cleaning misses them entirely. Our camera inspection identifies these configurations before we begin.
We use Rotobrush rotary brush agitation to dislodge debris from duct walls, followed by Nikro negative-air extraction to pull contaminants out under controlled suction, with Abatement Technologies HEPA filtration keeping particles out of your living space. For moisture-damaged flex duct in damp Des Moines crawl spaces, we extend agitation cycles and verify clearance with camera inspection. Call (469) 972-3151 for an exact quote on your home’s layout.
Yes, but only if the cleaning includes a camera inspection first, which is why we bundle inspection with every full-system service in Des Moines. Crushed or disconnected runs from original 1960s-1980s installations are invisible from vent openings and won’t be found by brush agitation alone. The camera shows us exactly where the damage is, and we give you a written repair price before any fix.
Yes. We service the equipment brands installed during Sound Insulation Program work and stock Honeywell, Aprilaire, and Guardsman filtration products for replacement and upgrade. Our technicians are familiar with the atypical duct layouts these retrofits created, which differ significantly from standard installations in Federal Way or Kent.
