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 | Kestrel Air Duct Cleaning
We clean and repair Trane duct systems across San Francisco, from the Sunset to Bernal Heights, with Air Duct Cleaning - San Francisco services tailored to local conditions. What makes our Trane work here different is that we start every job with a microbial assessment, not just a dust count, because the marine layer changes what’s actually growing inside your ducts. If your Trane system moves fog-dampened air through a Victorian crawl space, you’re dealing with a moisture problem as much as a dust problem. Call (469) 972-3151 for a straight answer and a written price before any work begins.
Why San Francisco Residents Choose Us for Trane Service
Dale Whitmore, our owner, cut his teeth on HVAC maintenance work and formal airflow training at Los Angeles Trade-Technical College before spending over a decade focused on the duct side of the system. What he learned there, and what our techs see every week in San Francisco, is that Trane equipment is built well but the ductwork attached to it rarely gets the same attention. We’re an independent Trane service provider, not a manufacturer-authorized shop, which means our credibility comes from hands-on work inside Trane air handlers and duct runs across this city, not from a certificate on the wall. We use OEM Trane components for critical parts like control boards and blower motors, and solid aftermarket equivalents for common wear items. Every tech arrives background-checked and uniformed, with Rotobrush, Nikro, and Abatement Technologies equipment in the van.

Common Trane Air Duct Cleaning Problems We Solve in San Francisco
- Flex duct collapse and liner delamination in Trane retrofits. Victorian and Edwardian homes built 1880-1915 never had central forced air. Ductwork got shoehorned through tight crawl spaces decades later, and that flex duct is now old, poorly supported, and often partially collapsed. The marine layer makes the liner delaminate faster here than almost anywhere in California.
- Evaporator coil and blower wheel microbial growth in Trane air handlers. In the Outer Sunset and Outer Richmond, systems sit stagnant for months because the mild climate rarely calls for heat. Fog-laden air settles inside the air handler, and mold takes hold on the coil and blower wheel. When you finally run the heat, you’re blowing that through the house.
- Return duct leakage and cross-connection in multi-unit Edwardian flats. Many San Francisco flats share duct runs between floors. A leaky return pulls fog-dampened crawl space air into a Trane supply run, which means your neighbor’s cooking smells, your landlord’s crawl space moisture, or worse ends up in your living room.
- Corrosion of Trane metal duct sections and fasteners. Crawl spaces in the western neighborhoods stay damp year-round. Condensation forms on cold duct walls during cool summer mornings, and over years that eats through metal sections and fasteners. We see rusted-out duct connections in San Francisco that would last decades in Sacramento.
- Musty odor on startup without visible dust. This is the classic fog-belt signature. The homeowner runs heat for the first time in weeks and gets hit with a damp, earthy smell. It’s not dust. It’s microbial growth on the flex duct liner, fed by Karl the Fog condensing on cold duct walls.
Trane Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s persistent marine layer, especially west of Twin Peaks in the Sunset and Richmond districts, keeps relative humidity high year-round. That moisture gets into crawl-space ductwork in ways that simply don’t happen in Oakland or San Jose. In the Outer Sunset, we routinely pull flex duct sections and find the interior liner visibly darkened with mold, a pattern tied directly to fog condensing on cold duct walls. Homeowners are often unaware because they almost never run heat long enough to notice reduced airflow. This is the information gain that matters for Trane owners: your system’s problem isn’t the equipment, it’s the environment. A Trane XR air handler in Phoenix collects dust. The same unit in the Outer Richmond collects mold. That’s why every Trane duct cleaning we do in San Francisco starts with a microbial assessment. We check for active growth before we ever put a brush in the duct. If we find it, we treat it. If we don’t, we tell you that too, and you pay for a cleaning, not a remediation you didn’t need.
Trane Models & Products We Service in San Francisco
We work on the full residential Trane lineup: the XR series, XB series, XLi series, and XC series, including their ducted air handlers and coil cabinets. For critical components like control boards and blower motors, we use OEM Trane parts when available. For common wear items like flex duct sections, fasteners, and filter housings, we use high-quality aftermarket equivalents that balance cost and reliability. For older Trane systems with extensive duct damage, we give you an honest assessment of whether targeted duct repair or full system replacement makes more sense. No upsell, no pressure. Our van carries the flex duct, sealant, and coil treatment products needed for most San Francisco jobs, so we’re not running back and forth to a supply house while your system sits open.
Trane Service Pricing in San Francisco
Most Trane air duct cleaning jobs in San Francisco run between $450 and $900 for a full system, depending on the number of returns, the accessibility of crawl spaces, and whether we’re dealing with a single-family Victorian or a multi-unit Edwardian flat with shared runs. If microbial growth is present and coil treatment or flex duct replacement is needed, that adds to the scope and the price. A video inspection is included, so you see what we see before and after the work. We give you a written price before any work begins, and the 365-Day Done Right Promise covers the work in writing. If it falls short within the guarantee period, we return and make it right at no charge. Call (469) 972-3151 for a free estimate and an honest read on what your system actually needs.

FAQs - Trane Air Duct Cleaning in San Francisco
That musty smell is microbial growth on your flex duct liner or evaporator coil, caused by fog-dampened air sitting in your ducts for weeks at a time. In the Sunset, the marine layer keeps crawl spaces damp year-round, and condensation forms on cold duct walls even in summer. When you finally run heat, the warmth releases that musty odor into your living space. The fix is our Dryer Vent Cleaning in San Francisco paired with duct cleaning, microbial assessment and, if needed, coil treatment and flex duct replacement. Call (469) 972-3151 and we’ll inspect what’s actually growing in there before recommending anything.
Yes, we clean Trane ductwork in multi-unit Edwardian flats across San Francisco, including buildings with shared or cross-connected duct runs between floors. Shared runs complicate the scope because we have to determine where your system ends and your neighbor’s begins, and whether return leakage is pulling crawl space air into your supply runs. We map the runs, seal what’s leaking, and clean what’s yours. The written price accounts for the building’s duct configuration before we start, so there are no surprises mid-job.
In the Sunset, Richmond, and other fog-belt neighborhoods, we recommend inspecting Trane ductwork every 2 to 3 years and cleaning as needed. The marine layer means microbial growth can establish itself faster here than in drier cities, even when you don’t see visible dust. If you rarely run your heat, the system sits stagnant for months, which is exactly when mold takes hold. A video inspection during a routine check catches problems before they become musty surprises on the first cool night. Call (469) 972-3151 to schedule an inspection, and we’ll tell you honestly whether cleaning is warranted or whether you can wait.
Supply ducts push conditioned air into your rooms, and return ducts pull room air back to the air handler. In a San Francisco Victorian, the return side is often more contaminated because it’s the side that draws fog-dampened air directly from crawl spaces and wall cavities. Supply ducts in these retrofits tend to collect what the return pulls in, plus whatever delaminates off the flex duct liner. We clean both, but we pay particular attention to return runs in Victorian homes because that’s where cross-contamination and microbial growth typically concentrate. The process is the same negative-air extraction with brush agitation, but the diagnosis and treatment differ by run.
We use OEM Trane components for critical parts like control boards and blower motors when they’re available. For common wear items like flex duct sections, fasteners, and filter housings, we use high-quality aftermarket equivalents that match or exceed OEM spec while costing less. The decision is always disclosed in writing before work begins. For older Trane systems with extensive duct damage, we’ll give you an honest repair-versus-replace assessment so you can choose what makes sense for your home and budget. Call (469) 972-3151 for a free estimate and a clear parts recommendation specific to your Trane model.
