Air Duct Cleaning Company in Chinatown, CA
Air duct repair in Chinatown usually means tracing original sheet-metal or retrofit flex runs through a century-old masonry building, not swapping a filter in a suburban closet. We work inside dense pre-1940s mixed-use structures where restaurant exhaust, residential returns, and shared mechanical chases often cross in ways that create real contamination and fire-damper problems. Everclear Air Duct Cleaning has served Chinatown since 2017, and we bring Rotobrush and Nikro equipment into buildings where access is tight, layouts are irregular, and the ductwork itself is often older than the building’s current use. Call (833) 620-5944 when you need a technician who can trace which duct actually serves which unit before anyone opens a panel.
Why Chinatown Homes Are Different
Chinatown’s 94108 zip code is dominated by early-1900s brick and masonry mixed-use buildings: ground-floor restaurants and shops with tenement-style apartments above, plus narrow infill structures along alley-adjacent lots. Most of these buildings were never designed for modern central HVAC. Ductwork here is typically original galvanized sheet metal or retrofitted flex runs squeezed into tight shafts and shared chases that run floor to floor through the building. A “duct cleaning” call in Chinatown often turns into a job of separating grease-laden restaurant exhaust from residential return air, confirming which duct actually serves which unit, and checking fire dampers for SFFD compliance before anyone touches the coil.
The marine-influenced San Francisco fog makes things worse. Mild but persistently damp air means duct systems in Chinatown more often grow microbial and odor problems from moisture and condensation than from extreme heat or cold. Restaurants add kitchen exhaust moisture into the mix, compounding condensation inside shared chases. Duct interiors stay damp, dust adheres, and smells migrate between units. This is not a single-family HVAC problem. It is a stacked-building, mixed-use problem, and it requires equipment and methods that account for how these old buildings actually breathe.

Our Main Chinatown Services
Most Chinatown property owners and managers call us for two things: a full cleaning of duct systems that have not been properly serviced in years, and dryer vent work that addresses a leading residential fire hazard in buildings where vent runs are long and often shared. Both jobs in Chinatown require understanding how the building’s original construction affects access and airflow.
Air Duct Cleaning in Chinatown
Air duct cleaning in Chinatown means getting inside systems that run through century-old masonry, tight shafts, and shared chases. We connect Rotobrush rotary brush systems and Nikro HEPA-rated vacuums to ductwork that often serves multiple units and has not been mapped properly. The job is not just brushing registers; it is confirming airflow paths, identifying cross-contamination between restaurant exhaust and residential returns, and removing years of grease-tinged dust and microbial growth from damp interior surfaces. See our Air Duct Cleaning in Chinatown page for full pricing and specific sub-jobs.
Dryer Vent Cleaning in Chinatown
Dryer vents in Chinatown’s older buildings often run long, irregular paths through shared chases, sometimes venting through masonry or terminating in hard-to-reach locations. Lint accumulation in these runs is a dryer vent fire risk, and in mixed-use buildings, a blocked vent affects units above and below. We clean the full run from dryer to exterior termination, removing compacted lint and confirming airflow with professional measurement. See our Dryer Vent Cleaning in Chinatown page for cost ranges and what to expect on site.
Air Duct Repair in Chinatown
Air duct repair in Chinatown starts with one hard truth: most of the ductwork in 94108 was installed before modern sealing standards existed, and San Francisco’s damp marine air has been degrading it for decades. We regularly find disconnected runs, crushed flex in tight shafts, and gaps at old sheet-metal joints that pull kitchen exhaust, crawlspace air, or neighboring-unit air into residential returns. Left alone, these leaks mean you pay to heat or cool air that never reaches the room, and you breathe air that was never supposed to be in your apartment. Our Air Duct Repair work replaces or reseals those sections and gets the system moving air from the inside out, not just at the registers.
Ductwork Repair
Signs you need it
Rooms that never reach temperature, dust returning to surfaces within days of cleaning, or a noticeable cooking smell from a neighboring restaurant inside your apartment are all signs of duct leakage or disconnection in Chinatown’s shared-chase buildings.
What it costs in Chinatown
Ductwork repair in Chinatown typically falls between $300 and $850 depending on access difficulty and how many sections need sealing or reattachment.
How we do it
We locate the leak with visual inspection and pressure testing, then seal joints with mastic or replace damaged flex sections, and confirm airflow at the register before we leave.
Air Duct Replacement
Signs you need it
Ductwork with rust-through holes, collapsed flex, pest contamination, or sections that were never properly sized for the unit they serve warrants replacement rather than patch repair.
What it costs in Chinatown
Air duct replacement in Chinatown generally runs $1,200 to $3,800 depending on linear feet of duct, chase access, and whether we are working in a single unit or a shared shaft.
How we do it
We pull the failed sections, size the replacement to the actual airflow demand, install new flex or sheet metal with proper support and sealing, and test the full run for leaks before reconnecting.
HVAC Duct Installation
Signs you need it
New construction within older Chinatown shells, gut renovations, or any situation where an existing duct system was never adequate for the unit’s square footage calls for proper HVAC duct installation rather than another patch.
What it costs in Chinatown
HVAC duct installation in Chinatown typically starts around $2,000 and runs to $6,500 for a full new run in a single apartment or restaurant space, with access difficulty being the biggest variable.
How we do it
We map the airflow requirements first, then run correctly sized duct through available chases, seal every joint, install fire dampers where code requires, and balance the system before handoff.
What Air Duct Repair Costs in Chinatown
| Item | Typical range in Chinatown |
|---|---|
| Ductwork repair (sealing, reattaching sections) | $300 – $850 |
| Air duct replacement (per unit) | $1,200 – $3,800 |
| HVAC duct installation (full run, single space) | $2,000 – $6,500 |
Access is the main cost driver in Chinatown. When we have to work inside a narrow mechanical shaft, behind a party wall, or around active restaurant exhaust, the hours go up. We quote one flat price per system before work starts, and that price does not change once we are on site.
How long does air duct repair take in Chinatown?
Most repair jobs in Chinatown take half a day to a full day. Replacement or new installation in a shared chase can run two to three days because access is tight and fire damper work cannot be rushed. We will give you a firm timeline when we quote.
Do I need a permit for duct repair in Chinatown?
Simple sealing and reattachment of existing ductwork typically does not require a permit. If we are installing new duct runs or altering fire dampers in a mixed-use building, San Francisco code may require one. We can tell you definitively after a site inspection. Call (833) 620-5944 for a free estimate.

FAQs About Air Duct Cleaning Company in Chinatown
Most Chinatown jobs are scheduled within one to three business days. We coordinate directly with property managers and restaurant owners for building access because many jobs require getting into shared chases or working around kitchen exhaust hours. Call (833) 620-5944 and we will give you a firm window.
Yes. That is the core of our Chinatown work. We trace which duct serves which unit, confirm fire dampers meet San Francisco Fire Department restaurant exhaust requirements, and address grease build-up before cleaning or repairing any residential return air path. This is the job most duct cleaners in the city will not take on.
Yes. Every Chinatown job includes before-and-after photos of the actual duct interior, so you can see what was removed and confirm the surfaces are clean. The work should be visible and confirmable, not something you take on faith. That is the entire point of hiring us.
If your Chinatown building’s ducts have not been properly serviced, or you suspect cross-contamination between a restaurant exhaust and your apartment’s return air, call (833) 620-5944. We will inspect, quote one flat price, and show you the work when it is done.

What Chinatown Customers Say
"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
- Diego Delgado"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."
- Paul Schaefer"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
