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.

Why Sterling Residents Choose Us for Trane Service
We’ve been in enough Sterling attics to know the difference between a 1969 Sterling Park split-foyer and a 1994 Cascades colonial without checking the address. Tomas Reyes, our owner, grew up in Queens and learned the trade at Triangle Tech in New York before spending nearly twenty years working HVAC and duct systems up and down the East Coast. He runs CleanRun on a straightforward principle: the camera goes in first, and every recommendation gets backed by a still frame or a written measurement.
That principle matters more in Sterling than most places. The original Sterling Park subdivision and the Cascades-era developments sit barely a mile apart, but the Trane systems in those homes need completely different approaches. We carry OEM-equivalent Trane-compatible parts for coils, blower motors, and cabinet seals, plus high-quality aftermarket flex duct and mastic for repairs where OEM isn’t practical. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. And every job, since our first one in 2013, concludes with a Documented Photo Record included as standard.
Sterling service area homeowners don’t need another contractor who treats every house like every other house. They need someone who knows that a Trane XR16 in Sterling Park can have the same model number as a Trane XR16 in Cascades and still present two entirely different duct problems.
Common Trane Air Duct Cleaning Problems We Solve in Sterling
- Fiberglass batt degradation in Sterling Park’s original metal trunks. The rigid galvanized steel supply trunks in 1967-1975 homes were wrapped in early-generation fiberglass batt insulation that has compressed or crumbled over five decades. We regularly find this material actively shedding fibers into the airstream, clogging Trane evaporator coils and coating blower wheels. The fix isn’t a vacuum pass; it’s HEPA-contained removal, metal trunk cleaning, and new duct wrap with sealed seams.
- Flex duct liner delamination in Cascades-era homes. Trane systems installed in 1985-2000 townhomes and colonials used flexible duct with polymer liners that crack and separate from the wire helix after 25-35 years. Northern Virginia’s humidity accelerates this. We scope these runs with a camera, replace delaminated sections with new flex duct, and reseal plenum takeoffs with mastic.
- Biological growth on Trane cased coils and blower wheels. Sterling’s humid subtropical summers push attic temperatures above 130°F, and the condensation that forms on cold coils mixes with clay dust and pollen to form a paste that restricts airflow. This raises static pressure across the system and forces the compressor to work harder. Our coil treatment removes this buildup without damaging the aluminum fins.
- Sagged flex trunks creating debris traps in two-story colonials. Heat and condensation cycles in unconditioned attics cause long Trane flex supply trunks to sag into low spots. Water pools there. Debris accumulates. Mold follows. We see this most often on the long trunk runs serving second-floor bedrooms in Cascades colonials built in the early 1990s.
- Failed mastic seals at plenum takeoffs pulling attic air into returns. When the seal between a Trane air handler plenum and the main trunk fails, the return side pulls in attic dust, insulation fibers, and whatever else is up there. In Sterling’s older homes, this often means the crumbled remains of that original fiberglass batt. We reseal with fresh mastic and mechanical fasteners where the joint has separated.

AfterTrane Service in Sterling: What Local Conditions Mean for Your Equipment
Sterling contains two distinct housing eras colliding in the same zip code, and that collision changes how we approach every Trane job. The original Sterling Park subdivision, built 1967-1975, harbors some of Loudoun County’s oldest forced-air systems with mid-century sheet-metal ductwork now 50+ years old. Meanwhile, the massive Cascades and other Dulles Corridor subdivisions built 1985-2000 are hitting the 25-35-year threshold where flexible duct liners crack, delaminate, and mastic seals fail. Two separate waves of severely deferred duct maintenance are converging simultaneously in a way not seen in newer Ashburn to the west or more mixed-age Herndon to the east.
For Trane owners, this means we don’t arrive with one generic checklist. A Trane XR16 paired with a TWE air handler in Sterling Park needs fiberglass batt remediation and metal trunk cleaning. The same model number in Cascades needs flex-liner inspection, possible replacement, and mastic resealing at plenum takeoffs. The equipment is familiar. The ductwork behind it is not. We scope each Trane job by neighborhood era, and the camera shows us which era we’re working with before we write a single line of the scope.
Trane Models & Products We Service in Sterling
We work on the Trane systems actually installed in Sterling homes, not a theoretical catalog. That includes XR16 and XR17 air conditioners paired with TWE/TW series air handlers; XV18 and XV20i variable-speed systems; S9V2 and S8X2 furnaces with matched cased coils; and Trane CleanEffects and Perfect Fit air filtration cabinet systems.
Our parts approach is straightforward. We use OEM-equivalent Trane-compatible components for coils, blower motors, and cabinet seals when they’re available and make sense for the repair. For duct repairs, we use high-quality aftermarket flex duct and mastic where OEM sourcing isn’t practical. If a Trane air handler or coil is heavily corroded, or if the heat exchanger is compromised, we tell you honestly when repair no longer makes financial sense. No phantom problems. No inflated scope. The inspection camera goes in before the quote comes out.
Trane sales & service from our crew means documented evidence, not a sales pitch.
Trane Service Pricing in Sterling
Whole-system Trane air duct cleaning in Sterling typically ranges from $380-$650 for most single-family homes, with larger systems or homes requiring fiberglass batt remediation or extensive flex duct repair running toward the higher end. Here’s how pricing breaks down:
- Standard whole-system cleaning: $380-$480 - covers supply and return duct runs, registers, grilles, and basic blower compartment access for visible debris removal
- System with coil treatment included: $480-$580 - adds evaporator coil cleaning and fin inspection, recommended when the camera shows buildup restricting airflow
- Extensive remediation (fiberglass batt removal, multiple flex duct replacements, or full mastic resealing): $580-$650+ - scoped after camera inspection, with written line-item pricing before work starts
What drives cost: home size, number of duct runs, accessibility of the air handler and plenum, and whether the camera reveals conditions that need repair before cleaning can be effective. Every estimate is free, includes the camera inspection, and delivers a written price under Haven Standard Clause 1 before any work begins. No per-vent pricing. No coupon bait.

FAQs - Trane Air Duct Cleaning in Sterling
We can clean it, but Dryer Vent Cleaning in Sterling alone isn’t enough. The crumbling fiberglass batt must be HEPA-vacuumed and removed first, then the metal trunks are cleaned, seams are sealed with mastic, and new duct wrap is installed. This is standard remediation for Sterling Park homes, not a full duct replacement. Call (571) 487-7204 and we’ll camera-inspect to confirm the condition.
The polymer liner inside flex duct from that era cracks after 25-35 years, especially in Northern Virginia’s humidity. Condensation gets through to the insulation layer, mold grows, and the return side pulls that odor into your living space. We camera-scope to find the damaged sections, replace them with new flex duct, and reseal plenum connections. The musty smell usually disappears within days.
These filtration cabinets protect the equipment downstream, but they don’t clean the ductwork upstream of the filter. Dust and debris still accumulate in return trunks and supply runs. We clean the full system including the filter cabinet itself, checking for bypass gaps where unfiltered air could be slipping around the media.
Attic temperatures above 130°F in July and August cause repeated expansion and contraction of flex duct, accelerating liner delamination and mastic failure. The heat also increases condensation on cold supply trunks, creating the moisture that feeds mold in low spots. We inspect for these thermal-stress failures on every Sterling job.
Yes. We service Trane systems across both housing eras, and the approach is different for each. Sterling Park homes typically need metal trunk remediation and coil cleaning; Cascades homes need flex duct inspection and plenum resealing. The camera inspection tells us which applies before we write the scope.
