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.
Air Duct Cleaning Company in San Francisco, CA
Full-system air duct cleaning in San Francisco typically runs $450 to $850 for a single-family home, with most jobs completed in one visit. What drives the real cost is the city’s unusual housing stock: pre-war gravity furnaces, shared duct chases in multi-unit buildings, and decades of salt-fog corrosion that turns routine cleaning into structural remediation. We’re Hollis Air Duct Cleaning, and our San Francisco crews handle the conditions that suburban duct cleaners rarely see. Call us at (361) 326-5060 for a written estimate before any work begins.
Why San Francisco Homes Are Different
San Francisco’s housing is old, tight, and built for a climate that never needed air conditioning. Most of the city predates 1950: Victorian and Edwardian row houses in the Richmond and Sunset, 1920s stucco in the Mission and Bernal Heights, post-war towers in the northeast. These homes were designed with gravity furnaces and simple sheet-metal ducts, or early flexible duct runs threaded through unheated basements, roof cavities without attics, and shared wall chases between units.
The marine layer is the other factor. Cool, damp, salt-heavy air from the Pacific floods crawlspaces and wall cavities year-round. We’ve opened ducts in the Sunset where galvanized steel had corroded through from decades of fog, and in the Richmond where original 1930s return-air paths were literally open floor-joist cavities, not ducts at all. No suburban market deals with this combination of age, density, and corrosion. When we clean in San Francisco, we’re often cleaning the building’s structural framing, not just metal pipes.
Multi-unit coordination adds another layer. Because most housing is attached or stacked, a single job may require landlord-tenant access agreements and coordination with neighbors’ shared chases. We build that into our scheduling, not into surprise charges.
Our Main San Francisco Services
San Francisco homeowners call us for three core jobs, each shaped by the city’s housing and climate conditions.
Air Duct Cleaning in San Francisco
Our full-system cleaning uses Rotobrush rotary brush systems and Nikro negative-air machines to remove debris from the entire duct run, not just reachable registers. In San Francisco, this often means addressing rodent debris, mold, and deteriorating interior duct lining found in pre-war systems. We photograph the before condition, clean every accessible section, and show you the after. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in San Francisco is scheduled by our Bay Area office with crews dispatched locally.

Dryer Vent Cleaning in San Francisco
Dryer vents in San Francisco’s older buildings often run through shared wall chases or long horizontal routes to exterior walls, creating lint traps that standard brushes can’t clear. We use professional-grade rotary tools and inspect the full run with a camera when access is limited. Blocked dryer vents are a genuine fire hazard, and in multi-unit buildings, one clogged vent can affect neighboring units. Dryer Vent Cleaning in San Francisco includes a written condition report and our standard upfront pricing.

Duct Sealing in San Francisco
San Francisco’s uninsulated crawlspaces and salt-corroded seams leak heated air into places that never see a register. We apply duct sealing mastic and mechanical fasteners to restore pressure balance, which matters especially in homes where “ducts” include open joist cavities. Sealing is often the right follow-up to cleaning in pre-1950 housing. Duct Sealing in San Francisco is priced by the system, not by the foot, with the full cost written before work starts.

What pushes San Francisco prices toward the higher end: multi-unit access coordination, corroded or damaged duct requiring repair before cleaning, and homes with original gravity-furnace systems where “ductwork” includes structural cavities. What doesn’t change the price: the number of vents. We price by the system, not by the register, so your written quote is the number you pay.
