Trane Air Duct Cleaning in San Lorenzo, CA
We provide independent Trane air duct cleaning across San Lorenzo, and the one thing that separates our work here is simple: we know what 70-year-old ductwork does to a Trane system. Most San Lorenzo homes went up in the late 1940s and 1950s, which means original sheet-metal trunks, dried-out tape, and joints that have worked loose under the house. That directly affects how your Trane air handler breathes, so we clean and seal the full path, not just the registers. Call (855) 382-9257 for a free estimate.
Frank Peralta started Duct Cleaning Castro Valley in 2012 after years in the ventilation trade across the East Bay. He studied HVAC systems at Chabot College in Hayward, and he still scopes every duct system before and after the work so you can see exactly what changed. Our team works on Trane equipment throughout San Lorenzo with the understanding that a cleaning is only half the job. The other half is making sure the ducts stay connected to the equipment.
Why San Lorenzo Residents Choose Us for Trane Service
We carry professional-grade equipment that belongs on this kind of work. Rotobrush rotary brushes dislodge debris inside the duct runs. Nikro HEPA-rated extraction captures what comes loose. Abatement Technologies negative-pressure containment keeps that dust from drifting back into your living room during the process. That matters when you are cleaning ducts in a 1950s ranch where someone has been living with the same air path for decades.
San Lorenzo is unincorporated Alameda County, so there is no city building department here. Duct work and HVAC changes fall under county permitting, and we have worked around that reality long enough to know what it means for scheduling and scope. We are not a Trane dealer and we are not authorized by Trane. We are an independent service provider, which means we diagnose what is actually in your house, not what a warranty manual assumes should be there. That independence is why homeowners in San Lorenzo call us when their Trane system is moving air through ductwork that predates the equipment itself.
Our scope includes air duct cleaning, air duct repair, and dryer vent cleaning. One point of contact for the entire ventilation system. We also understand the IAQ side of things, with working familiarity across Honeywell, Aprilaire, and Guardsman products.

Common Trane Air Duct Cleaning Problems We Solve in San Lorenzo
- Separated supply trunks under the house. Original 1950s sheet-metal runs with friction-fit joints have a habit of pulling apart over decades. We find this all the time around the San Lorenzo Village area, where crawl-space dust gets drawn straight into the Trane air handler and coats the evaporator coil.
- Dried-out tape and failing mastic at the plenum. The taped seams on old metal ductwork do not last forever. When that tape lets go, static pressure drops. The blower works harder, and dust settles in the return. We re-seal those connections so the Trane system moves air the way it should.
- Corrosion on older XR coils from damp winter air. San Lorenzo sits near the bay, and those cool, foggy summers plus damp winters put moisture in crawl spaces. Trane all-aluminum evaporator coils in older XR systems can develop a slight surface film that traps dust and cuts airflow. Cleaning restores heat exchange.
- Return chases never sealed to the furnace cabinet. In a lot of San Lorenzo ranch homes, the return path was framed in the 1950s and never properly tied to the Trane furnace. Attic or crawl-space air gets pulled in, bypassing the filter entirely. We close those gaps so filtered air is actually filtered air.
- Sixty-plus years of accumulated dust in supply runs. Even a clean system accumulates debris over enough decades. We find everything from construction dust to pet hair to the odd toy part. HEPA extraction gets it out rather than just knocking it loose.
Trane Service in San Lorenzo: What Local Conditions Mean for Your Equipment
Because San Lorenzo is unincorporated Alameda County, duct modifications here require county permits. We have been through enough of those jobs to know what triggers a permit and what does not, and we will tell you straight before work starts. Around San Lorenzo Village, we routinely see 1950s tract homes where original duct seams have separated under the house. A Trane XR14 or XR15 installed in the last decade might be pulling crawl-space dust directly into the supply air through a joint that failed thirty years before the unit was manufactured. That is the local reality: the equipment is newer than the ductwork, and the ductwork is the problem. Our video inspection catches it, and our sealing keeps it from coming back.
We recently serviced a Trane XR14 system in a 1950s ranch home near San Lorenzo Village. The homeowner complained of dust and a musty smell every time the heat kicked on. Our video inspection found a separated friction-fit joint on the main supply trunk under the house, pulling crawl-space dust straight into the air stream, plus dried-out tape on the plenum. We reconnected and mastic-sealed the joint, cleaned the full supply and return system, and the homeowner reported noticeably cleaner air and quieter operation. Clean ducts don’t need a sales pitch, the before-and-after scope footage does that work.
Trane Models & Products We Service in San Lorenzo
We work on Trane XR, XB, and XV series systems throughout San Lorenzo, including the XR13, XR14, XR15, XB13, XB14, XV18, and XV20i. Our technicians know the cabinet airflow patterns, coil configurations, and duct interface quirks on these units. We use quality parts that fit the equipment: OEM Trane parts for critical components like blower motors and coils when available, and quality aftermarket seals, mastic, and flex duct for duct repairs. On older XR systems with a failing coil, we give you an honest repair-versus-replace assessment, because sometimes a 20-year-old unit with a leaking coil does not justify the labor. If your Trane unit is in good shape and your ducts are the weak point, we clean and seal them for a longer service life.
We are an independent shop, so you get a straight diagnosis of what is there. No warranty-manual assumptions. No brand talk without evidence from the video scope.

FAQs – Trane Air Duct Cleaning in San Lorenzo
Yes, in most San Lorenzo homes we can clean the full supply and return system and mastic-seal the joints without replacing the ductwork. Original sheet-metal trunks from the 1950s are often in workable shape once the loose seams are resealed. We will show you the video scope so you can see it yourself. Call (855) 382-9257 and we will give you a straight read on what your ducts actually need.
Most likely a joint has separated on the supply trunk under the house. In San Lorenzo’s 1950s tract homes, those friction-fit joints were never meant to last 70 years. When one opens up, the blower pulls crawl-space air into the supply, and that dust lands in your living space. We find it with a video inspection and seal it with mastic.
It depends on the scope. San Lorenzo is unincorporated, so Alameda County permitting applies, not a city building department. We will tell you before any work starts whether your job triggers a permit, and we handle the paperwork side so you do not have to sort through county forms.
For most San Lorenzo homes, every four to six years is reasonable. The marine-influenced air here puts moisture into crawl spaces, which mixes with dust in old metal ducts. If you have pets, young kids, or anyone with allergies, you might go closer to every three to four years. Frank Peralta has a daughter with asthma, so he tends to lean conservative on that number. Call (855) 382-9257 if you suspect buildup, and we will scope it first.
We see a mix of XR13, XR14, and XR15 systems, with some XB and XV units in newer retrofits. The duct issues are usually the same regardless of model: separated under-house joints, dried-out tape at the plenum, and return chases that were never sealed. The Trane unit itself is often fine. The ductwork around it is the weak point. Call (855) 382-9257 for a free estimate and we will scope your system to see what is actually happening.
