HVAC Decontamination in San Francisco, CA
Opening, assessing, and restoring the system that touches every room — for households in San Francisco and across San Francisco County, held to the sensitized-occupant standard and independently verified.
Why this matters in San Francisco
The service is standard; the building stock is not. What follows is the San Francisco-specific picture, plus how households across San Francisco County get matched to providers held to the sensitized-occupant standard.
Fog-belt city with year-round marine humidity, minimal sunshine drying in western districts, and wind-driven rain. Edwardian and Victorian stock with zero-lot-line party walls, unvented cavities, and chronic single-pane condensation.
Where the work starts in San Francisco
- Fog-side and north-facing elevations for chronic condensation loading
- Unvented wall cavities and single-pane condensation zones in original assemblies
- Wind-driven rain entry at exposed elevations and unmaintained penetrations
- Shower and tub assemblies past their service life
- Water-heater closets and laundry connections
What's included
- Opened-equipment inspection: coil compartment, blower assembly, plenum interiors
- Duct material assessment: sheet metal versus porous liner and duct board
- Mechanical cleaning of metal components that can be verified clean
- Replacement of colonized porous components — liner, duct board, affected flex
- Condensate system correction: drainage, pan, float switch
- Filtration upgrade sized to the system's static pressure, sealed against bypass
- Blind duct cleaning with no equipment inspection
- Fogging 'sanitizer' through the ductwork
- UV lights sold as remediation for an already-contaminated system
A mechanical system that passes opened-equipment inspection and supports — rather than sabotages — your whole-house clearance.

Edwardian and Victorian stock with zero-lot-line party walls, unvented cavities, and chronic single-pane condensation. Providers who work these exact failure modes find sources faster and scope work more accurately than generalists applying a national template.
What standard is the work held to?
The sensitized-occupant standard: written scopes, verified negative-pressure containment where remediation is involved, no fogging or biocide-and-leave treatments, chemical disclosure, and third-party verification as the release condition for final payment.
