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.

AfterTrane Air Duct Cleaning in San Francisco, CA | Linden Air Duct Cleaning
We offer Air Duct Cleaning - San Francisco for Trane ducted systems, sealing and cleaning them across the city every week. The work here differs from any other market because the marine fog layer, not air conditioning runtime, is what fouls Trane coils and ductwork in this city. If you own a Trane system in San Francisco, call us at (980) 447-2498 for a straight answer before anyone schedules a visit.
We’re independent, not a Trane-authorized dealer. That matters in your favor: we diagnose the actual retrofitted equipment found in San Francisco’s Victorian and Edwardian housing stock rather than reading from a corporate playbook. Our crews work on Trane XR, XB, and XV residential systems constantly, and we document findings with video inspection before recommending any work. Contact Trane sales & service support is something we know cold, even though we’re not factory-affiliated.
Why San Francisco Residents Choose Us for Trane Service
Most Trane systems in this city were retrofitted into buildings that predate forced air by decades. Marcus Veale, our owner, learned airflow diagnostics and duct system mechanics through the HVAC program at Los Angeles Trade-Technical College, and he’s spent more than a decade on the exact kinds of cramped, jury-rigged retrofits that dominate the Haight, Noe Valley, and the Mission. We’ve seen what fog-belt humidity does to a Trane cased coil that never cycles on.
We use OEM Trane parts for blower motors, control boards, and coil components when they’re available, and quality aftermarket equivalents where OEM supply is slow or the item is commodity like flex duct, mastic, and filter media. Every job gets a written price before work begins, every tech arrives background-checked and photo-badged under the Threshold Standard, and every repair carries a written 365-Day Done Right Promise. For full coverage details, see our San Francisco service area page.
Common Trane Air Duct Cleaning Problems We Solve in San Francisco
- Mildew on Trane cased coils in the fog belt. In the Outer Sunset and Outer Richmond, marine-layer humidity infiltrates poorly sealed return plenums and flex-duct joints, so the coil face and drain pan grow mildew even when the system rarely runs at all. We clean the coil, treat the pan, and seal the leaks that fed the moisture in the first place.
- Dust-caked Trane blower wheels in Victorian retrofits. Trane XR and XB furnaces retrofitted into balloon-frame cavities often pull return air through unsealed floor and wall chases. That coats the blower wheel and secondary heat exchanger with dust and biological growth. We clean both and seal the chase openings.
- High static pressure on older Trane variable-speed air handlers. Trane XV80 and XV95 systems with ECM blower motors are sensitive to crushed or undersized flex runs, which we see constantly in Noe Valley and Mission stacked flats. Reduced airflow leads to coil freeze-up even in mild San Francisco weather. We identify the crushed sections and replace or repair them.
- Biofilm in Trane condensate traps during long off-cycles. San Francisco’s cool, damp climate means many Trane systems sit idle for months. Biofilm grows in the condensate trap and drain line, backing water into the plenum and saturating duct insulation. We clear the line, clean the trap, and treat the area to slow regrowth.
- Duct insulation saturated from return-side condensation. When humid fog-belt air meets cold supply ducts in an uninsulated crawlspace, condensation soaks the duct liner. We remove saturated insulation, clean the duct, and re-insulate with sealed material.
Trane Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s persistent marine fog layer keeps western neighborhoods like the Outer Sunset in near-constant high humidity for weeks at a stretch, and that moisture drives duct contamination in a way that simply doesn’t happen a few miles east in the sunnier Mission or Potrero Hill microclimates. Technicians working the Outer Sunset regularly pull flex duct sections with visible mold colonies from homes whose thermostats have never been set above 68°F and whose AC switch has never been touched. The fog does the damage entirely on its own. It’s a pattern inland California cities like Sacramento or Fresno never see, because summer runtime dries their ductwork out.
For Trane owners, this means your coil and return-side ductwork are at risk even if your system runs only a few hundred hours a year. The ambient humidity is the enemy, not compressor wear. A cleaning strategy that works for a Trane system in Fresno, where hot summers bake the plenum dry, won’t address what’s happening inside your ducts in the Outer Richmond. We build our San Francisco Trane work around sealing the return side first so the fog has fewer entry points, then cleaning the coil and duct surfaces the humidity has already affected.
Trane Models & Products We Service in San Francisco
We work on Trane XR and XB residential split-system air handlers and outdoor units, Trane XR80, XR95, and XB80 gas furnaces with cased coils, and Trane XV80 and XV95 variable-speed communicating furnaces. We also service Trane CleanEffects air filtration and Trane ComfortLink II communicating thermostat systems when the ductwork or coil needs attention.
Parts sourcing matters here. We keep common OEM Trane blower motors, control boards, and coil components available for fast San Francisco turnaround, and we use quality aftermarket flex duct, mastic, and filter media where OEM supply would stretch the timeline without any quality benefit. For older Trane equipment in San Francisco, our repair-vs-replace call is based on coil condition, cabinet rust, and whether the duct system can be sealed without tearing into original Victorian framing. Sometimes the honest answer is that cleaning and sealing buys you years; sometimes the coil has simply reached the end.
Trane Service Pricing in San Francisco
| Service | Typical Range in San Francisco |
|---|---|
| Whole-home air duct cleaning (Trane system) | $450 – $850 |
| Evaporator coil cleaning (add-on with duct cleaning) | $100 – $250 |
| Duct sealing (per system, mastic-based) | $350 – $700 |
| Video inspection (standalone) | $100 – $200 |
| Return-side flex replacement (per section) | $150 – $350 |
San Francisco pricing runs slightly above national averages because of the access issues built into Victorian and Edwardian retrofits: ducts threaded through original subfloor cavities, return chases that were never designed for forced air, and tight closet air handlers that require more time to work around. What drives your total is system size, how many returns need sealing, and whether we’re replacing damaged flex sections or just cleaning them.
We give one flat price per system in writing before any work starts. No per-vent pricing, no call-day upsell. Call (980) 447-2498 and we’ll talk through your Trane setup and give you a real number.
