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.
Trane Air Duct Cleaning in Seattle, CA | Morton’s Air Duct Cleaning
We clean and repair ductwork connected to Trane heat pumps, air handlers, and furnaces across Seattle, and we do it as an independent provider, not a Trane-authorized shop. What makes our work here different is simple: we know how Seattle’s damp crawl spaces treat Trane equipment, and we price the whole job before we start. If you’ve got a Trane system pushing air through ducts that haven’t been touched in years, call us at (323) 918-4345 and we’ll tell you exactly what’s going on.
Why Seattle Residents Choose Us for Trane Service
Paul Adeyemi leads our crew, and he’s spent the better part of two decades working inside the walls and crawl spaces of homes across the Los Angeles basin. He learned ventilation mechanics hands-on at Los Angeles Trade-Technical College, and that grounding in how air actually moves through a system is what he brings to every Trane job we take in Seattle. We’ve worked on enough Trane sales & service calls to know the brand’s airflow patterns and coil geometries well enough that we can spot a restriction before we pull a panel. For Seattle specifically, that matters. The city’s older housing stock and damp marine air combine to create duct problems that a technician from a drier climate might never think to check.
Every visit starts with a written price before any work begins. Our techs wear shoe covers and lay drop cloths inside your home without being asked. We use Rotobrush and Nikro equipment for our Dryer Vent Cleaning in Seattle and ductwork, and we back the work with our 365-Day Done Right Promise. If it’s not right, we make it right.
Common Trane Air Duct Cleaning Problems We Solve in Seattle
- Mold on air handler cabinet insulation and coil fins. Trane air handlers in Seattle crawl spaces sit in 75 to 85 percent relative humidity for months at a stretch. Return air pulls that moisture through the cabinet, and mold takes hold on interior insulation and aluminum fins. We clean the cabinet, the blower, and the coil, then address the moisture source so it doesn’t come back next season.
- Undersized flex duct on heat pump retrofits. Many Seattle homes ran Trane gas furnaces for decades before a heat pump went in. The original flex runs were sized for furnace airflow, not heat pump airflow. Static pressure climbs, ducts sweat, mildew forms, and connections pull apart at collars in vented crawl spaces. We replace undersized runs with properly sized flex and seal every collar with mastic.
- Crushed or disconnected flex in hillside crawl spaces. On Queen Anne and Capitol Hill, we regularly find flexible ductwork that has collapsed or separated at its connections. Chronic moisture weakens the tape, and hillside framing settles unevenly over time. The system dumps conditioned air under the subfloor for years while the owner assumes their heating bill reflects normal Seattle energy costs.
- Dirty Trane XR and XL outdoor condensers. Fir needles, moss, and standing moisture accumulate on outdoor coils all year in Seattle. That restricts airflow and forces the blower to run longer, dirtier cycles. We clean the condenser coil and recommend clearing debris around the unit so the whole system moves air more efficiently.
- Construction dust trapped in Trane all-aluminum evaporator coils. The post-2021 retrofit wave in Seattle means thousands of Trane heat pumps got installed onto duct systems that were never cleaned first. Fine dust and debris from decades of furnace-only operation now coat those aluminum coils, causing partial blockage and musty supply air. Coil cleaning is part of our full system service.
Trane Service in Seattle: What Local Conditions Mean for Your Equipment
Seattle gets roughly 150 to 160 overcast or rainy days per year, and that number shapes everything about how Trane equipment holds up here. A heat pump retrofit in a Wallingford Craftsman or a Beacon Hill mid-century sits in a vented crawl space that never gets a natural drying cycle. The duct interiors never dry out. Mold spores and dust mites establish themselves in ways a technician in Phoenix or Denver simply doesn’t encounter. That means Air Duct Cleaning in Seattle after a retrofit is a moisture control job as much as a debris removal job. We’re not just vacuuming out dust. We’re checking whether the duct insulation has absorbed moisture, whether the flex runs are sweating, and whether the air handler cabinet needs drying and resealing before the next rainy season. A generic Trane page won’t tell you that. A generic Seattle duct cleaning page won’t either.
Trane Models & Products We Service in Seattle
We service the Trane XR series heat pump air handlers, XR and XB gas furnaces, XV variable-speed air handlers, and XR and XL outdoor heat pump condensers. For parts, we use Trane OEM-compatible filters, insulation, and mastic where fit and warranty concerns matter. Where aftermarket materials do the job better for Seattle’s crawl space conditions, we use quality flex duct, collars, and coatings that meet or exceed OEM durability. We stock common Trane-compatible filters and sealing materials locally so Seattle turnaround stays quick.
Trane Service Pricing in Seattle
Full system cleaning for a typical Seattle home runs between $450 and $900 for the entire duct system, depending on the number of returns and the condition of the flex runs. Evaporator coil cleaning adds $150 to $300. Flex duct repair or replacement is priced per run and quoted before we touch anything. The biggest cost driver here is access. Crawl space homes on hillsides take longer to work in safely than slab homes. Every quote is written and agreed to before work starts. Call (323) 918-4345 for a free estimate and we’ll give you a real number, not a teaser.

FAQs - Trane Air Duct Cleaning in Seattle
Yes, and ideally it should have been cleaned before the heat pump went in. Heat pumps move air differently than gas furnaces, and decades of settled dust, pet hair, and construction debris in old duct runs will coat your new Trane coil and restrict airflow from day one. If the install is already done, cleaning now will still protect the coil and clear the musty air. Call (323) 918-4345 and we’ll walk you through what your specific system needs.
That’s the damp season. From October through March, Seattle’s humidity sits high enough that duct interiors and air handler cabinets hold moisture. Mold grows on insulation and coil fins, and when the heat kicks on, the smell pushes through your vents. This is exactly the pattern we see in crawl space homes across the city. Give us a call at (323) 918-4345 for an inspection.
Yes. Trane all-aluminum coils are more corrosion-resistant than older copper-and-aluminum coils, but they still need careful cleaning. We use the correct cleaning agents and low-pressure rinsing so the fins don’t bend or strip. We’ve cleaned enough of these coils in Seattle to know exactly how far we can go without causing damage.
It’s a real possibility. Restricted airflow from a clogged coil, undersized flex runs, or collapsed duct sections forces the heat pump to work harder and run longer to hit its set point. In Seattle’s hillside homes, collapsed flex in crawl spaces is a frequent culprit. We’ll inspect the full system, find the restriction, and show you what we found before we touch anything. Call (323) 918-4345 for a free estimate.
