Why Lents Residents Choose Us for Trane Service
Richard Anderson, our owner and lead technician, grew up in Capitol Hill and has spent his adult life working in the homes and buildings he knows by name. After picking up HVAC fundamentals at Northern Virginia Community College, he narrowed his focus entirely to duct systems — a specialty he’s practiced across Washington for over eleven years now. That single-trade focus matters in Lents, where the combination of post-WWII ranch construction, original sheet-metal ductwork, and chronic crawl-space moisture creates contamination patterns that generalist HVAC crews miss entirely.
We don’t rotate through technicians. Richard runs every job himself or alongside his small crew, which means when something unusual turns up inside a Trane system — a silt line from the 2022 flood, a collapsed filter slot bypassing debris into a variable-speed motor — he’s the one making the call on the spot. Our 732 verified reviews averaging 4.9 stars reflect what happens when owner accountability meets professional-grade Rotobrush and Nikro equipment.
We use OEM Trane components for critical safety and performance parts — heat exchangers, motors, control boards — and certified aftermarket alternatives for non-critical items like duct insulation and sealants. Repair over replacement, always, unless the unit is beyond economical service. That’s the difference between a specialist who lives in the ducts and a generalist who cleans them between furnace installs.
Common Trane Air Duct Cleaning Problems We Solve in Lents
- XV80 secondary heat exchanger corrosion from crawl-space moisture. The XV80’s aluminized steel heat exchanger doesn’t tolerate Lents’ sustained 70%+ crawl-space humidity well. We find corrosion scaling that flakes into supply air, and our cleaning protocol includes full exchanger inspection plus downstream duct agitation to remove settled oxide particles.
- S9V2 variable-speed blower motor failure from flood sediment. Fine silt from Johnson Creek events infiltrates motor bearings through unsealed duct joints. In Lents, this isn’t theoretical — we’ve pulled motors with visible grit packing the bearing races. Our cleaning includes full motor housing decontamination before reassembly.
- XR80 induced-draft fan bearing seizure from silt-laden intake air. The XR80’s compact fan assembly sits close to return ductwork. When flood silt bypasses collapsed filters or unsealed joints, it accumulates on fan blades and works into the bearing assembly. We disassemble and clean the full induced-draft housing, not just the accessible surfaces.
- XV20i communicating thermostat sensor drift from debris-laden return air. The XV20i’s sophisticated sensor network depends on accurate airflow readings. In Lents homes with original galvanized ductwork and deteriorating joint tape, return air carries enough particulate to coat sensor ports. Our cleaning includes sensor verification and recalibration check.
- Collapsed filter slots bypassing unfiltered air into all Trane models. The original sheet-metal duct systems common in Lents’ 1920s–1940s bungalows often have filter slots that have warped or separated from decades of moisture cycling. We document these bypass points during video inspection and include sealing recommendations in every Lents quote.
Trane Service in Lents: What Local Conditions Mean for Your Equipment
Lents sits squarely in the Johnson Creek flood corridor, and recurring high-water events regularly drive moisture into the crawl spaces and pier-foundation cavities beneath the neighborhood’s dense stock of post-WWII ranch homes — making mold and sediment contamination inside ductwork a chronic problem here that is measurably worse than in the higher-elevation SE Portland neighborhoods just a few miles uphill. Homeowners who experienced Johnson Creek flooding often don’t realize that below-grade and crawl-space duct sections can harbor active microbial growth long after surface water recedes.
The 2020 and 2022 high-water events left visible silt lines inside flex ducts of homes on SE 131st Ave and Luther Road — a physical watermark that standard register-vacuuming never reaches. We’ve developed a crawler camera and full system agitation protocol specifically for this pattern. Portland’s long damp season, November through April, drives crawl-space relative humidity consistently above 70%, which feeds mold growth inside supply and return runs. Lents’s position in the Johnson Creek lowlands amplifies this because poorly drained lots keep ground moisture elevated even between storm events. Unlike the drier West Hills or Clackamas Trane service areas to the southeast, Lents duct systems rarely get a true dry-out period through winter. For Trane owners, this means corrosion-prone heat exchangers and precision variable-speed motors face environmental stress that their original engineering specifications never anticipated.
Trane Models & Products We Service in Lents
We clean and service the full Trane residential line, with particular depth on the units we encounter most in Lents’ older housing stock: the XV80 two-stage gas furnace, the S9V2 high-efficiency variable-speed system, the workhorse XR80 single-stage, and the premium XV20i communicating variable-capacity heat pump. Each presents distinct duct-contamination vulnerabilities in floodplain conditions.
We stock OEM Trane heat exchangers, motors, and control boards for same-day repair when cleaning reveals component damage. For duct insulation, sealants, and non-critical hardware, we source certified aftermarket equivalents that meet or exceed Trane’s material specifications — keeping your repair cost-effective without compromising system integrity. Our Rotobrush and Nikro cleaning systems are the same units commercial restoration contractors deploy, not rental-grade equipment pushed through a residential franchise.

FAQs — Trane Air Duct Cleaning in Lents
Yes, we adjust our rotary brush speed and use lower-torque agitation on original galvanized ductwork with deteriorating tape. In many Lents bungalows, the tape has already failed — we document this during video inspection and can reseal with mastic as part of the cleaning scope. Call (877) 335-1974 for a free inspection of your specific duct condition.
Absolutely. Flex duct inner liners trap moisture between the wire coil and insulation layer, and galvanized steel ducts develop condensation on hidden surfaces long after visible water recedes. We’ve found active mold colonies six months after homeowners considered the space “dry.” Our moisture meter readings and crawler camera inspection reveal what surface appearances hide. Call (877) 335-1974 if your crawl space flooded — we’ll check what you can’t see.
Yes. The XV80’s secondary heat exchanger needs direct visual inspection for corrosion scaling that standard cleaning protocols skip. We also verify that condensate drainage isn’t backing into ductwork from saturated crawl-space soil — a Lents-specific failure mode we’ve traced to at least a dozen systems. The cleaning itself uses our full agitation protocol, but the inspection sequence is tailored to floodplain corrosion patterns.
Johnson Creek silt — fine, mineral-laden sediment that settles in distinct horizontal lines showing flood height — plus mold species that thrive in sustained humidity rather than simple moisture events. Higher-elevation neighborhoods see pollen and dust; Lents systems carry the signature of repeated groundwater intrusion. Our field experience here has trained our eyes to read these patterns instantly.
Yes, duct sealing is one of our five core services. We use mastic and mechanical fasteners on flex joints, not tape that degrades in moisture. This won’t prevent flooding, but it significantly reduces sediment infiltration during high-water events. We can also recommend elevation or barrier improvements based on what we observe in your specific crawl space. Call (877) 335-1974 for an estimate that includes sealing scope.
