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.

AfterFast, Reliable Air Duct Cleaning Across Union Hill-Novelty Hill
Air duct cleaning in Union Hill-Novelty Hill typically runs $380-$620 for a full residential system, with most jobs completed in a single morning or afternoon. We’re the local team that shows up in the window we promised, puts the price in writing before touching a single vent, and backs the work with our 365-Day Done Right Promise. Call (469) 972-3151 for a free estimate.
We’ve been serving homes on the Sammamish Plateau long enough to know the pattern: builder-grade forced-air systems installed during the 1990s and 2000s tech-boom expansion are now twenty to thirty years old, and the persistent fog and marine moisture at this elevation keeps crawlspace duct runs damp year-round. That combination means Union Hill-Novelty Hill homeowners deal with mold colonization and heavy organic debris loads that lower-elevation Eastside communities simply don’t see as quickly. Our crews are dispatched from the Seattle office and know the plateau’s roads, housing developments, and the specific duct configurations common to homes built in that rapid-build era.
Why Kestrel Air Duct Cleaning Is Union Hill-Novelty Hill’s Preferred Air Duct Cleaning Company
Union Hill-Novelty Hill homeowners call us after they’ve been burned by the bait-and-switch routine: a coupon price that balloons once the truck is in the driveway, or a “cleaning” that was really just a shop vac run over the registers. We don’t work that way. The Kingswell Guarantee means you get a written price before we start, a defined arrival window, and a clean job site when we leave. If something fails within the guarantee period, we come back free.
Our technicians are background-checked, uniformed, and trained on professional-grade equipment: 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. We don’t send salespeople. We send technicians who understand that a 2002-built home near Redmond Ridge has different duct issues than a 1997 original near Union Hill proper, and they’ll explain what they’re finding in plain language.
Calls are answered by a live person, 24/7. Not a voicemail queue. Not an automated system. A real conversation, any time of day.
Residential Air Duct Cleaning in Union Hill-Novelty Hill
Residential Air Duct Cleaning in Union Hill-Novelty Hill means complete source removal from supply ducts, return ducts, trunk lines, and the air handler, not a surface wipe of visible vents. Most homes here are large, two-story single-family houses built during the 1990s and 2000s with standard builder-grade forced-air systems that are now reaching the age where duct lining degrades and debris accumulation becomes significant. A typical full residential cleaning in Union Hill-Novelty Hill runs $380-$620, depending on system size, accessibility, and whether video inspection reveals issues in the crawlspace runs.
We recommend residential cleaning when you notice musty odors after the HVAC cycles, visible dust buildup at registers, uneven heating or cooling between floors, or if your home has never had ducts cleaned since original installation. On the Sammamish Plateau, the combination of aging ductwork and persistent marine moisture makes the “never cleaned” scenario more common than homeowners realize.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull air back to the air handler. Both sides need attention. We use rotary brush agitation to loosen debris adhered to duct walls, then negative-air extraction to remove it completely. In Union Hill-Novelty Hill homes, we regularly find red alder pollen packed into return chases and microbial growth along supply trunk lines in damp crawlspaces.
Full System Cleaning with Video Inspection
We run a camera through the system before and after cleaning so you see what was there and what we removed. This matters especially for plateau homes where crawlspace runs are hard to access and easy to skip. The “after” footage goes in your job file, along with the written price and guarantee documentation.
Commercial Air Duct Cleaning in Union Hill-Novelty Hill
Commercial Air Duct Cleaning in Union Hill-Novelty Hill covers office buildings, medical clinics, retail spaces, and multi-tenant properties with larger-scale forced-air systems that accumulate debris faster due to higher occupancy and more frequent HVAC cycling. Most commercial jobs in this market run $800-$2,400 depending on square footage, system complexity, and whether the building has multiple air handlers or rooftop units. We schedule commercial work to minimize disruption to your operations, including early-morning or weekend slots when needed.
Union Hill-Novelty Hill’s commercial stock includes professional offices and light medical spaces built during the same 1990s-2000s expansion as the residential areas, often with the same rapid-build quality variations in duct sealing and insulation. We inspect trunk lines for leakage that pulls in unfiltered crawlspace air, and we document findings for facilities managers who need maintenance records for insurance or compliance.
Multi-Zone System Cleaning
Commercial buildings with multiple thermostats and zone dampers require systematic cleaning of each branch. We isolate zones during service to prevent cross-contamination, and we clean or replace filters as part of the job scope.
Post-Construction and Renovation Cleaning
Remodeling work in commercial spaces generates fine particulate that settles in ductwork. We perform source removal with HEPA-contained negative pressure, protecting occupied areas from redistribution of construction debris.
Trusted Brands We Service in Union Hill-Novelty Hill
We clean ductwork connected to all major HVAC brands, and we stock Honeywell and Aprilaire filtration products for Union Hill-Novelty Hill homeowners who want to maintain cleaner air between service visits. Honeywell media air cleaners and Aprilaire whole-house purifiers integrate with most forced-air systems common to plateau homes built in the 1990s and 2000s. We also carry Guardsman filtration products for specialized applications. If your system needs a filtration upgrade, we’ll recommend specific equipment based on what we find during cleaning, not a generic upsell. Parts are stocked locally for fast turnaround when replacements are needed.
Common Air Duct Cleaning Problems We See in Union Hill-Novelty Hill Homes
- Mold colonization in crawlspace trunk lines. The Sammamish Plateau’s persistent fog and elevated humidity keep crawlspace duct runs damp for much of the year. We’ve inspected homes where the homeowner smelled mustiness upstairs for two seasons before discovering microbial growth concentrated in the crawlspace trunk line, completely invisible from the living space.
- Red alder pollen packed into return-air systems. Red alder trees release some of the heaviest pollen loads in the Pacific Northwest each late winter, often before homeowners have changed filters after heating season. That fine organic particulate goes straight into return-air systems that may never have been cleaned since original installation.
- Poorly sealed trunk lines pulling in unfiltered air. Rapid-build-era construction quality varied considerably across the 1990s and 2000s expansion. We regularly find trunk lines with failed or missing sealant at joints, actively drawing crawlspace air, pollen, and debris into the system downstream of the filter.
- Blower motor and air handler contamination. Technicians who clean only ducts and ignore the air handler leave the source of re-contamination intact. Lint, biofilm, and debris accumulate on blower wheels and in condensate pans, then redistribute through freshly cleaned ductwork within days.
Pricing for Air Duct Cleaning in Union Hill-Novelty Hill, WA
Most full residential duct cleanings in Union Hill-Novelty Hill run between $380 and $620. Commercial systems typically start around $800 and scale to $2,400 for larger or multi-handler buildings. What moves you within that range: the number of supply and return vents, whether the system includes a basement or crawlspace air handler that’s harder to access, the condition found during video inspection, and whether additional services like dryer vent cleaning or filtration upgrades are performed during the same visit.

FAQs About Air Duct Cleaning in Union Hill-Novelty Hill
The Sammamish Plateau sits 400-500 feet higher than Bellevue and Kirkland, and that elevation catches more persistent fog, drizzle, and marine moisture. Relative humidity stays elevated around homes here for much of the year, especially in crawlspace and basement duct runs that lower-elevation communities simply don’t experience as acutely. Combined with twenty- to thirty-year-old builder-grade duct systems that have never been cleaned, the conditions are ideal for mold colonization. Call (469) 972-3151 for a free inspection if you smell mustiness when your HVAC cycles.
Expect significant debris accumulation, possibly degraded duct lining, and likely microbial growth in crawlspace runs if your home is on the plateau. We’ll run a camera first so you see exactly what’s in there. Most 1990s-2000s homes in Union Hill-Novelty Hill need a full source-removal cleaning including trunk lines, air handler, and blower motor. The job typically takes four to six hours for a large single-family home. Call (469) 972-3151 for a written estimate before any work begins.
No. Fogging or misting chemical into the system without physical source removal masks odor for a few weeks while mold colonies in damp crawlspace duct runs keep growing. We pulled a 2001 builder-grade system in the Novelty Hill area where the homeowner had been fogging “sanitiser” into the return for two seasons and still smelled mustiness in the upstairs bedrooms. Camera inspection showed microbial growth along the crawlspace trunk line and red alder pollen packed into the return chase. We set up negative pressure with HEPA filtration, ran agitation tools and source removal through supply and return ducts, and cleaned the air handler and blower motor. The smell was gone because the growth and debris were physically removed, not because anything was sprayed on top of it. Call (469) 972-3151 if you’ve already tried fogging and the problem returned.
Bad enough to significantly restrict airflow and degrade indoor air quality for weeks. Red alder releases some of the heaviest pollen loads in the Pacific Northwest, and in Union Hill-Novelty Hill that pollen goes straight into return-air systems that may not have been cleaned since the home was built. We’ve extracted packed pollen loads from return chases that were reducing system efficiency by 20 percent or more. The solution is source removal, not a better filter on top of twenty years of accumulated debris. Call (469) 972-3151 for a camera inspection.
Ask four questions before hiring anyone: Do they put the full price in writing before starting? Do they use negative-air extraction with HEPA filtration, or just a shop vac? Do they clean the air handler and blower motor, or only the ducts? Do they provide before-and-after video of your actual system? At Kestrel, the answer to all four is yes, and it’s documented on every job. The Kingswell Way requires it. Call (469) 972-3151 and we’ll explain exactly what your system needs.
Ready to get your ducts cleaned right? Call (469) 972-3151 for a free estimate. We’ll put the price in writing before any work begins, back it with our 365-Day Done Right Promise, and leave your home’s air system actually clean, not just sprayed with something that smells clean.
