Trane Air Duct Cleaning in Seattle, CA | Hollis Air Duct Cleaning

We provide independent Trane Air Duct Cleaning - Seattle across the metro area, and the one thing that makes our work different here is moisture. Seattle’s 150-plus rainy days and heat-pump-heavy housing stock mean Trane systems in this city fail differently than they do in drier markets, and duct cleaning here is less about dust and more about managing condensation, mold, and undersized ductwork. Our technicians know exactly how Trane XR, XL, and XV systems behave in Seattle’s wet crawlspaces and tight infill townhomes. Call (361) 326-5060 for a written, no-oblique estimate on any Trane system in Seattle.

Why Seattle Residents Choose Us for Trane Service

We’re independent Trane air duct cleaning specialists, not affiliated with or authorized by Trane. That independence matters, because we don’t answer to a manufacturer’s sales targets. We answer to what we find inside your ductwork. Roy Castellanos, who leads our team, trained in the sheet metal and air conditioning program at Los Angeles Trade-Technical College and spent years doing hands-on duct work before starting Hollis Air Duct Cleaning. He knows Trane cabinets, coils, and duct interfaces the way a mechanic knows a specific engine, because he’s opened hundreds of them.

For Trane owners in Seattle specifically, that brand familiarity translates into faster diagnosis. We know where Trane air handlers leak in humid crawlspaces. We know how Trane variable-speed blowers react to the tight, complex duct runs common in newer Seattle infill townhomes. And we stock OEM Trane parts for critical components like blower motors, control boards, and igniters, so when a Trane system in Seattle needs a repair alongside our Dryer Vent Cleaning in Seattle or duct cleaning, we’re not waiting on a parts shipment. We’re part of the Garrison Partners family, and every job runs on The Garrison Standard: arrive inside the quoted window, price it in writing before work starts, do it by the book, and leave the site clean. That’s not a slogan. It’s the operating code.

Key Takeaways:

  • Independent Trane specialists, not manufacturer-affiliated or authorized
  • OEM Trane parts for critical components, high-quality aftermarket materials for duct sealing and flex duct
  • Written price before any work begins, covered by the 365-Day Done Right Promise
  • Background-checked, uniformed technicians who know Seattle’s housing stock

Common Trane Air Duct Cleaning Problems We Solve in Seattle

  • Trane all-aluminum evaporator coils producing excess condensate. In heat pump mode, Trane coils generate more moisture than gas-furnace setups. When paired with undersized Seattle ductwork, that moisture overwhelms drain pans and wets nearby flex duct. We clean the coil, clear the drain path, and seal the duct connections so the water stays where it belongs.
  • Musty Trane air handlers in damp Seattle crawlspaces. Trane air handlers installed in crawlspaces often pull humid crawlspace air through cabinet seams and return leaks, feeding mold growth inside the blower compartment and downstream duct runs. We find this constantly in Seattle’s pre-1940 Craftsman bungalows where the crawlspace was never sealed.
  • Rusted heat exchanger sections on older Trane XR furnaces. Original Craftsman-era ductwork in Seattle runs through damp basements and crawlspaces. Return-air leaks introduce moisture-laden air, and that moisture finds its way to the heat exchanger. We clean the duct system and identify the return leaks so the corrosion stops progressing.
  • Trane variable-speed blowers running at high static pressure. Seattle’s infill townhomes have tight, complex duct runs. Trane variable-speed blowers are sensitive to static pressure, and high static leads to premature blower failure and uneven airflow. We measure static pressure during duct cleaning and flag where the ductwork is choking the system.
  • Flex duct sagging and collecting water in Seattle’s damp crawlspaces. This is the one problem we see in Seattle that drier markets rarely encounter. Sagging flex duct collects standing water from poor drainage, which creates a distinct musty odor and hidden mold. We repair or replace the sagging runs, re-support the duct, and seal the connections so water can’t pool again.

Trane Service in Seattle: What Local Conditions Mean for Your Equipment

Seattle’s housing stock is dominated by pre-1940 Craftsman bungalows and mid-century ranches with original ductwork that is often undersized, leaky, and riddled with asbestos tape. That matters for Trane owners specifically, because modern Trane heat pumps move air differently than the gas furnaces those ducts were designed for. The air is cooler, more humid, and the system runs longer in heating mode. When that cool, humid air travels through ductwork sized for a 1950s furnace, the result is condensation inside the ducts, mold growth on return grilles, and that musty smell homeowners notice when the system first kicks on. Newer infill townhomes in Seattle have the opposite problem: tight, complex duct runs that create pressure imbalances and strain Trane variable-speed blowers. We handle both ends of that spectrum.

Trane Models & Products We Service in Seattle

We service the full range of Trane residential HVAC equipment across Seattle. That includes Trane XR and XB series furnaces and air handlers, Trane XR and XL series heat pumps, Trane XV variable-speed air handlers, and Trane CleanEffects air filtration systems. When a critical component fails, like a blower motor, control board, or igniter, we use OEM Trane parts. For duct sealing, flex duct, and mastic, we choose high-quality aftermarket materials that perform as well or better in Seattle’s damp conditions. We’ll always tell you honestly if a Trane component is worth repairing or if replacement makes more sense given the age and condition of the rest of the system. That’s the straight answer you’ll get from us, every time.

Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, explained in plain terms on every job.

Trane Service Pricing in Seattle

Full Trane air duct cleaning in Seattle typically runs between $450 and $750 for a single-family home, depending on system size, number of returns, and accessibility. If we’re adding evaporator coil cleaning, that’s usually $150 to $300 more. Duct sealing runs $800 to $1,500 depending on how many leaks we find and how much mastic the system needs. Every estimate is written down before any work starts, and the price does not move at the door. What drives cost in Seattle specifically? Crawlspace access, sagging flex duct that needs replacement, and mold remediation on coils all add labor. A free estimate from us includes a visual inspection of the ducts, coil, and blower. No per-vent pricing, no teaser coupon that turns into a surprise invoice. Call (361) 326-5060 for an exact quote on your Trane system in Seattle.
