Carrier Air Duct Cleaning in Kenmore, WA | Landmark Air Duct Cleaning Service Washington
Carrier duct cleaning in Kenmore typically runs $350–$650 for a full residential system, with most jobs completed in a single visit. What sets our Carrier sales & service apart in Kenmore is the crawl space — the Sammamish River lowlands keep soil moisture persistently high here, and we’ve spent eleven years learning exactly how Carrier’s flex-duct insulation jackets and aluminum coils fail in that environment. If your Carrier system is pushing musty air or struggling with airflow, call us at (877) 335-1974 — we offer free estimates and same-day inspection in the 98028 area.

Why Kenmore Residents Choose Us for Carrier Service
Richard Anderson, our owner and lead technician, grew up in Capitol Hill and has spent the better part of his adult life working in Puget Sound homes he knows by name. After picking up his HVAC fundamentals at Northern Virginia Community College, he narrowed his focus entirely to duct systems — a specialty he’s practiced across Kenmore’s lake-river corridor for over eleven years now, including our Air Duct Cleaning in Kenmore.
That single-trade focus matters for Carrier owners. We’re not a general HVAC shop that added duct cleaning as an upsell. We run professional-grade Rotobrush and Nikro equipment — the same systems commercial restoration contractors use — and we stock OEM Carrier flex duct and mastic sealant for the repair work that Kenmore’s damp crawl spaces inevitably require. With 732 verified reviews averaging 4.9 stars, our volume and rating reflect what happens when the same owner-led crew handles every job from inspection through cleanup.
Richard runs every Carrier job personally or alongside his small crew. When something unusual turns up inside a duct system — and in Kenmore, it often does — he’s the one making the call on the spot. “If I can’t tell you exactly what I found and why it needed cleaning, I haven’t done my job.” That’s the standard we hold ourselves to.
Common Carrier Air Duct Cleaning Problems We Solve in Kenmore
- Collapsed flex-duct insulation from crawl-space humidity. Kenmore’s ground moisture wicks into Carrier flex-duct jackets until the fiberglass compresses and the inner liner flattens — we’ve measured 30–50% airflow loss before homeowners even notice the temperature imbalance upstairs. Our video inspection catches this before cleaning begins.
- Corroded aluminum evaporator coils. Carrier’s coils in Kenmore homes endure constant airborne moisture from the Sammamish River microclimate. We pre-treat coils with foaming cleaner before duct agitation, preventing the corrosion spread that premature brushing can accelerate.
- Leaky supply plenum seams in 1950s–1980s construction. Kenmore’s original snap-lock metal ducts have decades of ground-moisture exposure. We seal compromised Carrier plenums with mastic rather than tape — tape fails in damp crawl spaces within two seasons.
- Biofilm on Infinity series variable-speed blower wheels. Carrier’s 18VS and 25VNA8 systems run longer at lower RPMs, giving mold time to colonize the wheel. That biofilm throws off the motor load and can trigger control board error codes — we remove and hand-clean the wheel assembly when inspection warrants it.
- Mold-compromised duct liner beyond cleaning. In Kenmore’s wettest crawl spaces near the river, we’ve encountered liner so saturated that agitation would release spores into the home. We quote replacement with OEM Carrier flex duct in those cases — no point cleaning what’s structurally failed.
Carrier Service in Kenmore: What Local Conditions Mean for Your Equipment
Kenmore sits at the confluence of Lake Washington and the Sammamish River, creating a persistently damp microclimate that is measurably wetter than neighboring Bothell or Kirkland. Crawl-space ductwork here shows moisture-related failures like mold and duct-collapse at least twice as frequently as in homes just three miles east — making video inspection essential before any cleaning quote, unlike Carrier service in Lake Forest Park where conditions differ.
For Carrier owners specifically, this means trouble. The Comfort series FB4C and FV4C air handlers we encounter in Kenmore’s 1950s–1980s housing stock are often paired with flex-duct runs that have spent decades in unconditioned crawl spaces. The low-lying bowl where the river empties into the lake traps cold, foggy air through October into April; condensation forms on cold duct surfaces, and when vapor barriers fail, it forms inside the ducts themselves. Carrier’s aluminum coils — efficient and lightweight — corrode faster here than copper alternatives would. The Infinity series variable-speed blowers, designed for gentle, continuous circulation, end up recirculating mold spores if the ductwork upstream is compromised.
We’ve learned to treat Kenmore Carrier systems differently than identical models in drier Carrier service in Bothell neighborhoods. Pre-cleaning moisture readings. Coil treatment before agitation. Mastic, never tape, on any seal we touch. The river doesn’t negotiate, so our approach doesn’t either.
Carrier Models & Products We Service in Kenmore
We work on Carrier’s full residential and light-commercial lineup, with particular depth on the systems common to Kenmore’s housing stock:
- Comfort series: FB4C and FV4C air handlers — the workhorses in Kenmore’s mid-century splits and ranches, often paired with original flex duct that’s reached end-of-life in damp crawl spaces.
- Performance series: Heat pumps with variable-speed air handlers — we clean the full duct network and treat coils for the moisture corrosion these systems see along the Sammamish River corridor.
- Infinity series: 18VS and 25VNA8 systems — the variable-speed blower wheels require careful hand-cleaning when biofilm buildup appears; we never rush this step.
We stock OEM Carrier replacement flex duct and mastic sealant for structural repairs. For non-structural components — insulation jackets, filter racks, hardware — we source quality aftermarket equivalents to control cost without compromising fit or function. Every Kenmore job carries direct owner accountability from start to finish.
Carrier Service Pricing in Kenmore
Most Carrier duct cleaning jobs in Kenmore fall between $350–$650 for a full residential system, depending on home size, duct accessibility, and whether repair work is needed. Here’s how typical pricing breaks down:
- Standard full-system cleaning: $350–$450 (single air handler, up to 12 vents, accessible crawl space)
- Cleaning with video inspection: $400–$500 (recommended for all Kenmore crawl-space systems)
- Cleaning plus flex-duct repair/replacement: $500–$650 (common when moisture collapse has occurred)
- Coil treatment and blower wheel cleaning: $75–$150 add-on, depending on contamination level
What drives cost? Crawl-space accessibility in Kenmore’s older homes, the extent of moisture damage to flex-duct sections, and whether coil treatment is needed before duct agitation. Our free estimates include a full video inspection — no guesswork, no surprises when we open the crawl space hatch. Call (877) 335-1974 to schedule; estimates are free and we’re typically in Kenmore within 24–48 hours.

FAQs — Carrier Air Duct Cleaning in Kenmore
Kenmore’s Sammamish River microclimate is measurably wetter than Kirkland’s higher, drier elevation. That persistent ground moisture accelerates mold colonization and dust-mite growth inside crawl-space ductwork — typically twice the failure rate of homes just three miles east. Your Carrier system isn’t defective; its environment is simply more demanding. We also handle Carrier repair in Inglewood-Finn Hill where conditions differ. Call (877) 335-1974 for a moisture-assessment inspection and we’ll show you exactly what your ducts are facing.
We always inspect with video before recommending replacement. If the inner liner is intact and the insulation jacket hasn’t wicked moisture to collapse, thorough cleaning plus mastic sealing of plenum seams often extends service life by years. When we find liner delamination or compressed flex-duct runs — common in Kenmore’s wettest crawl spaces — we quote OEM Carrier replacement for those sections only, preserving what still functions. Call (877) 335-1974 for a free video inspection and honest assessment.
Not with proper technique. Our Rotobrush and Nikro systems use controlled agitation — we match brush stiffness to duct material and never force brushes past collapsed sections. For Kenmore homes with decades of neglect, we start with video inspection to map the system condition, then clean progressively rather than aggressively. Richard Anderson oversees this personally. Call (877) 335-1974 to discuss your system’s history and schedule a careful first cleaning.
Usually, yes — in Kenmore’s climate, musty supply-air odor typically indicates mold or biofilm somewhere in the duct path, often on the evaporator coil or inside a moisture-compromised flex-duct section. It can also signal a dead rodent or standing water in a low duct run. We identify the source with video inspection before any cleaning begins; treating the wrong problem wastes money and leaves the odor. Call (877) 335-1974 — we’ll find the source and quote the fix.
Coil treatment is available as an add-on service, not automatically bundled. We inspect the coil during our video assessment — in Kenmore’s humid microclimate, Carrier aluminum coils often need foaming treatment before duct agitation to prevent corrosion spread. We quote this separately so you’re not paying for unnecessary work on a clean coil, but we strongly recommend it when inspection shows contamination. Call (877) 335-1974 for an estimate that reflects your system’s actual condition.
