Air Duct Cleaning Company in Redwood City, CA
Air duct repair in Redwood City starts with a question most cleaning-only companies never ask: is the ductwork actually sound? Between pre-war bungalows in 94063 whose original sheet-metal runs have been patched for decades and tight lagoon-side houses near Redwood Shores that trap bay dampness, plenty of Redwood City homes move air through ducts that leak, sag or never came back together after a remodel. Our technicians have up to 10 years of experience and work with Rotobrush rotary systems and Nikro HEPA containment, so we can clean it and fix it. Call (866) 894-2153 for a free estimate; one flat price per system, agreed before work starts.
Why Redwood City Homes Are Different
No neighboring Peninsula city packs this much housing variety into one service area. Redwood City runs from 1920s-40s single-story stucco bungalows in the central blocks out to mid-century ranch homes on the hillside streets toward 94062, then jumps to 1990s-2000s tight construction along the Redwood Shores lagoon in 94065. Each era fails differently.
The older homes often still carry original rigid sheet-metal duct or early flexible duct that has been retrofitted piecemeal. We find undersized runs, taped-over joints and disconnected sections that quietly dump conditioned air into a crawl space. The lagoon-side houses were built sealed and weather-tight, so they leak less but hold more – stale air and moisture complaints dominate there.
Then there’s the climate. Redwood City sits in a mild, fog-influenced bay pocket with wet winters and a long damp shoulder season. Ductwork here lives in a low-drying environment, and mildew in flex duct and plenum liners is a recurring concern, especially on crawl-space and garage-sited runs. Rainy-season moisture intrusion drives far more of our indoor-air calls here than summer heat ever does.

Our Main Redwood City Services
Most Redwood City homeowners call us about one of two things: the ducts themselves, or the dryer vent in the wall.
Air Duct Cleaning in Redwood City
Duct cleaning in Redwood City means more than vacuuming registers. We put the system under negative pressure with Nikro HEPA-filtered equipment, then run a Rotobrush rotary brush through each branch line to break loose the dust film that clings to flex duct and plenum liners. In the older central homes it’s the patched runs that hold the most debris; in the Redwood Shores houses it’s the damp, trapped air that needs addressing. If you want the full walkthrough of what the visit covers, see Air Duct Cleaning in Redwood City. Estimates are free, and the price is set per system.
Dryer Vent Cleaning in Redwood City
Lint packed into a dryer vent is a fire risk, not a housekeeping annoyance, and it’s the reason we treat this as a safety job. In Redwood City’s older bungalows the vent often runs long and turns hard through a wall cavity, which traps lint faster than a short modern run. In the tighter Redwood Shores homes, screens and sealed exterior hoods can cut airflow without anyone noticing until dry times stretch out. We clear the full run and check the exterior hood and damper. Full details are on Dryer Vent Cleaning in Redwood City.
Air Duct Repair in Redwood City
Air duct repair in Redwood City is what we get called for after someone has already paid for a cleaning and the airflow still feels wrong. In the pre-war bungalows around 94063 and the mid-century ranch homes toward 94062, decades of patchwork on rigid sheet-metal and early flex duct leave undersized runs and disconnected joints that no amount of vacuuming fixes. On the lagoon side, the Redwood Shores houses in 94065 were built tight and weather-sealed, and their garage and crawl-space duct runs sit in steady bay dampness and salt air, so we routinely find condensation-stained plenum liners and mildew in houses that look dry and modern. That’s the case for Air Duct Repair as a standalone job rather than an upsell.
Ductwork Repair
Signs you need it
You need ductwork repair when rooms heat or cool unevenly, you hear whistling or rattling at a register, or you find a joint that has come apart behind a taped seam or a disconnected collar at the plenum.
What it costs in Redwood City
Ductwork repair in Redwood City typically runs $180 to $450 for a single run or joint, and a written estimate sets the final price once we’ve seen the access.
How we do it
We camera or hand-inspect each suspect run under negative pressure, reseal the joints with mastic and proper mechanical fasteners rather than tape alone, re-support sagging flex, and re-test airflow at the registers before we leave.
Air Duct Replacement
Signs you need it
Replacement is the right call when flex duct is torn, crushed, or lined with mildew you can see or smell, when runs are badly undersized for the system, or when a liner has started shedding into the airstream.
What it costs in Redwood City
Air duct replacement in Redwood City typically estimates from $1,200 to $4,500 depending on the number of runs, the access, and the duct type, with one flat price agreed before work starts.
How we do it
We isolate and seal the system, remove the failed duct sections, install new duct sized for the blower and insulated for the bay’s damp conditions, then pressure-check and confirm airflow at every register.
What Air Duct Repair Costs in Redwood City
These are typical ranges for Redwood City jobs. The written estimate you get after we inspect sets the final price.
| Item | Typical range in Redwood City |
|---|---|
| Single duct run or joint repair | $180 – $450 |
| Duct replacement (partial system) | $1,200 – $2,500 |
| Duct replacement (full system) | $2,500 – $4,500 |
Does air duct repair actually fix uneven cooling in older Redwood City homes?
Often, yes. Undersized runs and disconnected joints in the pre-war bungalows push most of the air into a crawl space. Repairing and resealing those runs restores balance at the registers. Call (866) 894-2153 for a free estimate.
Can you repair ducts in a crawl space under a Redwood Shores home?
Yes. Crawl-space and garage-sited runs are exactly where we find condensation-stained liners and mildew in 94065. We work under negative pressure with HEPA containment so dislodged debris is captured, not redistributed. Call (866) 894-2153 to book an inspection.
Brands We Service in Redwood City
We work with Honeywell and Aprilaire filtration and humidity controls, Guardsman components, and the Rotobrush and Nikro equipment that does the cleaning. That means we can recommend and fit the filter and humidity upgrades that make sense after a cleaning, without pretending to be a general HVAC outfit. Most arrangements happen within a few days of the estimate. See our brands for the full list.

Same-day work is often possible when the schedule allows. We answer 24/7, and crews dispatch from 7am to 7pm, Sunday through Friday. A call outside dispatch hours is booked into the next opening. Call (866) 894-2153 to check the nearest slot.
Duct cleaning itself usually needs neither. Larger duct replacement can require a permit, so check with Redwood City’s building department before work starts, and ask your HOA about any exterior vent hood changes on the Redwood Shores side.
Clear access to the furnace, the attic hatch or crawl-space door, and any registers under furniture. Note which rooms feel stuffy or uneven, and mention any musty smell. That helps the technician pinpoint damp or disconnected runs instead of guessing.

- Steve Meyer"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
