Air Duct Cleaning Company in SoMa, CA
Air duct repair in SoMa usually means working inside a converted warehouse or a mid-rise tower, not a single-family home with attic access. Ducts here run through old brick-and-timber lofts, shared risers, and rooftop units that bake in fog-cooled air year-round. Our crews know the difference between a 1906 timber truss and a 1990s steel-frame chase, and we bring the right extraction and sealing equipment for the building type. If your space has leaky flex duct retrofitted through exposed ceiling chasework, call (833) 467-6681 and we’ll start with a straight answer, not a brochure.
Why SoMa Homes Are Different
SoMa isn’t a uniform housing market, and the ducts follow the architecture. The neighborhood stretches from the fog-cooled streets near the Bay to the warehouse blocks south of Market, where early-1900s brick buildings have been converted into lofts and live/work condos. Those conversions rarely got new duct systems. They got retrofit flex ducts pulled through old freight elevator shafts, over original timber trusses, and into tenant-side ceilings where access panels were an afterthought. There is no standard layout, and no standard access.
Marine-layer damp is part of this too. Fog and cool temps mean HVAC operates in a narrow band year-round in SoMa, and sealed office-condo spaces with limited outdoor airflow hold onto whatever the system pulls through. We regularly see buildup in returns running through old warehouse flues; those runs often have no accessible cleanout, which changes how we set up negative-air containment. A job here frequently means coordinating with a building HOA or property manager, because the duct beyond your unit wall belongs to the building.
SoMa’s newer towers – the 1980s through 2000s mid-rises and high-rises around 94104 – have their own challenge: central building systems with long vertical risers and rooftop AHUs where tenant-side access ends at a fire damper or a branch collar. A duct repair in these buildings is usually an association compliance issue as much as a comfort issue.

Our Main SoMa Services
Two services account for most of the calls we field from SoMa: air duct cleaning and dryer vent cleaning. Both are covered on their own pages, and both are jobs that get more complicated in this neighborhood’s building stock.
Air Duct Cleaning in SoMa
In SoMa’s lofts and live/work units, the ductwork often hasn’t been cleaned since the building converted, because access is genuinely difficult. We run Rotobrush rotary extraction on flex and sheet-metal runs, match Nikro industrial extraction to longer commercial risers and rooftop loops, and contain everything with Abatement Technologies negative-air equipment. Exposed spiral duct in a loft looks industrial but still collects the same fine dust a suburban system does. For the full scope of this service in SoMa, see Air Duct Cleaning in SoMa.
Dryer Vent Cleaning in SoMa
Dryer vents in SoMa convert units are a genuine fire-safety issue. The vent run often travels up from a stacked laundry closet, through an old plumbing chase, and out a roof or parapet wall that hasn’t been inspected in years. Lint packs into elbows behind living spaces, not at the dryer. We treat this as a dedicated service with its own checklist, not an add-on. Read the details at Dryer Vent Cleaning in SoMa.
Air Duct Repair in SoMa
Air duct repair in SoMa almost always starts with air that should be coming out of a register and isn’t. Leaky, disconnected, or crushed ducts in a converted loft or an older building’s riser system quietly dump conditioned air into wall cavities and between-floor spaces, and in a tight office-condo conversion that means one unit freezing while another roasts. Fog-cooled damp air, a retrofit flex run, and 100-year-old building cavities are a recipe for duct failure. We find and fix the leaks at the source, because cleaning a damaged system just recirculates the problem. Our repair work is a core part of Air Duct Repair, and in SoMa it usually involves working inside the building structure, not a standard attic.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat set point, visible dust streaking around ceiling grilles in a live/work loft, or a utility bill that climbs every summer are the typical red flags in SoMa.
What it costs in SoMa
Patching disconnected or crushed duct runs in SoMa typically costs $190 to $380 per opening, depending on access and the duct material.
How we do it
We locate the damaged section with visual, pressure, or smoke testing, seal it with mastic and appropriate duct tape at the joint, and re-support sagging runs to restore design airflow.
Air Duct Replacement
Signs you need it
Ducts with corrosion from bay moisture, collapsed flex where tenants stored items on the ceiling, or material too deteriorated to seal should be replaced rather than patched.
What it costs in SoMa
Whole-system replacement in a SoMa unit typically runs $2,850 to $7,800, though most jobs fall between $3,400 and $5,200 depending on duct length and chase access.
How we do it
We fabricate or order the correct size, pull the new run through the existing chases, seal every joint, and confirm static pressure before the system goes back online.
What Air Duct Repair Costs in SoMa
| Item | Typical range in SoMa |
|---|---|
| Ductwork patch / re-seal per opening | $190 – $380 |
| Flex duct replacement per run | $280 – $540 |
| Whole-unit duct replacement (small loft) | $3,400 – $5,200 |
Can you fix a duct leak in a SoMa loft without opening walls?
Often yes. We access exposed spiral duct and retrofit flex through existing ceiling chases and utility closets, but concealed runs inside walls may require a small access cut.
Do I need HOA approval for duct repairs in a SoMa building?
Usually yes for anything beyond your unit’s tenant-side branch. We help you document the damage and coordinate with the property manager, since shared riser work is a building matter.
Brands We Service in SoMa
We work with Honeywell media filters, Aprilaire dehumidifiers, and Abatement Technologies containment units. Most common parts are stocked in our Oakland warehouse and arrive in SoMa without a week of back-and-forth. See our brands for the full equipment list.

What SoMa Customers Say
"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
- Wade Reed"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Beatriz Hernandez"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
