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, NY | CleanRun Air Duct Cleaning
We provide independent Air Duct Cleaning - San Francisco for Trane systems, and the work here is different from anywhere else we operate. The marine layer and century-old retrofit ductwork combine to create mold and debris patterns in Trane systems that you simply don’t see inland. We document every run with camera work before and after, so you see what was actually inside your ducts. Call (806) 606-6902 for a written estimate.
CleanRun Air Duct Cleaning has worked on Trane systems in San Francisco since 2013. We’re independently owned and operated under the Haven Standard. We are not a Trane authorized dealer or factory affiliate, and we don’t claim any manufacturer warranty or endorsement. What we do claim is documented, photographed, model-specific work on Trane equipment throughout the city’s residential stock. If you own a Trane system in San Francisco, we can tell you what’s inside your ducts before we touch them.

Why San Francisco Residents Choose Us for Trane Service
Our technicians work on Trane systems weekly across San Francisco’s Victorian and Edwardian row houses and the Sunset District’s stucco tract homes. That repetition matters. Trane’s XR and XL series air handlers behave differently in a fog-side crawl space than they do in a dry suburban basement, and our HVAC Cleaning in San Francisco has seen enough of both to know what to look for before opening a panel.
Tomas Reyes, owner and lead technician, grew up in Woodside, Queens, in a building whose ductwork hadn’t been touched since the Carter administration. He confirmed that himself once he got into the trade. He completed his HVAC coursework at Queensborough Community College before spending years on residential and commercial duct systems across all five boroughs. Today he runs CleanRun with one rule: camera inspection first, written scope second, no work until the customer has seen what’s inside. That approach travels well to San Francisco, where ducts hide in places most homeowners never look.
We stock OEM Trane parts where they affect airflow, control, or safety: blowers, control boards, coil cabinets. For generic duct fittings, flex connectors, and sealants, we use quality aftermarket equivalents only when the OEM item is discontinued or not sold separately. Every job starts with a written price under Haven Standard Clause 1, and every job ends with a photo record of the inside of every run. No exceptions.

Common Trane Air Duct Cleaning Problems We Solve in San Francisco
- Mold colonization behind Trane evaporator coils. On fog-side blocks in the outer Sunset and outer Richmond, the coil stays damp for weeks between infrequent cooling cycles. That damp coil face is a mold substrate. We remove the coil access panel, photograph the coil and the plenum behind it, and clean with negative-pressure extraction so spores don’t get pushed into the living space.
- Marine-layer silt in multi-speed blower wheels. Trane’s multi-speed blowers pull fine airborne silt through the return side, and in San Francisco that silt is sticky with salt and moisture. It coats the blower wheel, reduces airflow, and strains the motor. In retrofitted Victorian return chases, the problem compounds because the chase itself is often unsealed and pulling crawl-space air.
- Condensation wicking into unsealed Trane duct connections. In Sunset District “Sunset Special” homes built between the 1930s and 1950s, under-slab sheet-metal ducts were installed without vapor barriers. The soil around them is chronically damp. We routinely pull wet debris from these runs, and when the Trane branch connections were never sealed with mastic, rust and musty discharge follow.
- Asbestos-adjacent duct wrap on pre-1980 Trane-installed branches. Edwardian and Victorian crawl spaces in San Francisco often contain asbestos-containing duct insulation or surrounding materials. Our technicians treat these jobs as containment-first scopes: no aggressive brushing, no high-pressure air that could disturb the wrap, and a written protocol before any panel comes off.
- Dormant system stagnation. San Francisco’s mild climate means Trane forced-air systems often sit idle for months. Debris settles, moisture lingers, and biological growth gets a foothold. When the system finally kicks on, it distributes whatever grew during the downtime into the supply registers.
BeforeAfterTrane Service in San Francisco: What Local Conditions Mean for Your Equipment
The sunset-facing blocks west of 19th Avenue sit inside the city’s designated fog corridor. Our techs routinely find Trane systems there with return-air dew point above the crawl-space temperature. That’s a condensation pattern you do not see in Noe Valley or Potrero Hill, where night skies are clearer and duct surfaces stay drier. The consequence shows up on Trane coils and blower housings: consistent moisture film, even in summer. In the outer Sunset around 32nd Avenue near Ortega, we pulled a Trane XR14 air handler from a crawl-space duct run where the unsealed sheet-metal return had wicked damp soil moisture into the blower housing. Our tech removed tarry lint and a visible mold mat from the blower wheel, video-scoped the under-slab branch, and resealed every joint with mastic before reinstalling. The owner said the musty bedroom smell was gone within a day.
San Francisco’s dominant housing stock of Victorian and Edwardian row houses, largely built from the 1880s through 1915, was never designed for forced-air systems. Ductwork was retrofitted into shallow floor cavities, under-building crawl spaces, and wall chases. These irregular configurations substantially increase cleaning time because access is tight and runs are rarely straight. When we quote a Trane duct cleaning in San Francisco, the price reflects that access reality. A straightforward suburban trunk line is not what we’re working with here.
Trane Models & Products We Service in San Francisco
We service the full range of residential Trane equipment found in San Francisco homes. That includes the RunTru by Trane line, common in rental units and small condo retrofits, the Trane XR series (XR13, XR14, XR15), frequently matched to existing ductwork in row houses, and the Trane XL series (XL16i, XL18i), often seen in larger Victorians with multi-zone retrofits. We also work extensively on Trane Hyperion air handler lines, which show up regularly in crawl-space and closet retrofits throughout the city.
Our parts policy is straightforward. We use OEM Trane parts where they affect airflow, control, or safety. That means genuine Trane blowers, control boards, and coil cabinets. For generic duct fittings, flex connectors, and sealants, we’ll use a quality aftermarket equivalent when the OEM item is discontinued or not sold separately. For Trane duct-connected components in older San Francisco retrofits, we recommend cleaning and sealing over component replacement whenever mold or leakage is localized. We’re also direct when a Trane coil or blower housing is too far gone to clean safely. The photo tells you what’s in there. Everything else is just paperwork.
Trane Service Pricing in San Francisco
Air duct cleaning on a Trane system in San Francisco typically runs between $450 and $1,200 depending on home size, access difficulty, and contamination level. A single-system Victorian with accessible ducts in a dry crawl space will land at the lower end. A fog-corridor Sunset Special with under-slab sheet-metal runs and active mold will land higher. We write the exact price before any panel comes off, and it’s the price you pay. No per-vent pricing, no add-ons discovered mid-job.
Every estimate includes a camera inspection of your Trane system’s return side, supply trunk, and branch runs. You’ll see the debris yourself before you agree to anything. Call (806) 606-6902 to get a written number.

FAQs - Trane Air Duct Cleaning in San Francisco
Why does my Trane system in the outer Richmond smell musty even though I don’t have a plumbing leak?
Your ducts are pulling fog-saturated air into a cool crawl space, and moisture is condensing inside the return runs. The outer Richmond sits directly in the fog corridor, and a Trane coil or blower housing that never fully dries will grow biological material. It’s a condensation problem, not a leak. Call (806) 606-6902 and we’ll camera-scope the return side to confirm what’s growing and where.
Do Trane systems in older San Francisco row houses need different duct cleaning than newer homes?
Yes. Victorian and Edwardian retrofits have irregular duct runs, tight access, and often asbestos-adjacent materials. We use lower-agitation tools in these homes and we treat any pre-1980 duct wrap as potentially asbestos-containing until proven otherwise. A newer home with open basement access is a faster, simpler job.
Can fog damage a Trane evaporator coil even if I rarely run air conditioning?
Yes. The coil stays damp because the return air in San Francisco’s fog belt is consistently humid. Infrequent cycling means less condensation flushing and more standing moisture on the coil face. We open the coil cabinet, photograph what’s there, and clean with negative-pressure extraction. The coil itself usually survives; the mold on it is the problem.
Should I have my Trane ductwork sealed before or after cleaning in a Sunset District home?
Clean first, then seal. Sealing before cleaning traps debris and moisture inside the runs. We clean the full system, video-scope to confirm the interior is clear, then seal every accessible joint with mastic. In Sunset Special under-slab runs, sealing after cleaning is the only sequence that makes sense because you’re locking out the soil moisture that caused the problem.
What is the most common Trane duct problem you see in Forest Hill and West Portal homes?
Unsealed return chases pulling air from unconditioned wall cavities and crawl spaces. Forest Hill and West Portal sit west of Twin Peaks and get measurable fog exposure, so those unsealed returns pull damp, salty air directly across the Trane blower. The fix is sealing the chase and cleaning the blower wheel. Call (806) 606-6902 for an exact written quote on your system.
