Air Duct Cleaning Company in Redwood City, CA
Air duct repair in Redwood City usually starts with a call about one of two things: a room that won’t heat in the winter, or a musty smell that comes through the registers whenever the system kicks on. In homes across 94061, 94062, 94064 and 94065 we find the same story: older sheet-metal ductwork in low crawlspaces, disconnected at the seams, or flex duct that’s collapsed under its own weight. Duct Cleaning Mountain View has served Redwood City since 2015, and we bring professional-grade Rotobrush and Nikro equipment plus the repair tools to fix what cleaning alone can’t. Call (866) 528-3938 to schedule an assessment.
Why Redwood City Homes Are Different
Redwood City calls itself “Climate Best by Government Test,” and that mild, stable weather shapes how duct systems here actually behave. Most Peninsula homeowners run forced-air heating only a few weeks each year, which means air handlers sit idle for months while dust, rodent debris, and the fine grit from wildfire-smoke season settle into the return plenums. In the older flats near downtown and Mount Carmel, duct runs are short and awkward, often squeezed through low crawlspaces and slab-on-grade chases where a technician has maybe eighteen inches of clearance to work. We routinely find rodent nests and acorn debris jammed into return plenums in those neighborhoods after fall, something hillside and Redwood Shores builds rarely see.
Meanwhile, the 94065 Redwood Shores waterfront and 94062 hillside homes face a different issue: more outdoor air and bay fog pulling through attic-run flex duct, which can sag, kink, or separate at the collar. The older pre-war bungalows and Victorians around downtown often have sheet-metal ductwork from the asbestos-era, still functionally sound but leaky at every joint. Mix in recurring smoke events from the hills, and the trade here becomes less about cleaning furnace ducts after heavy heating and more about making an older, mixed-age system work with modern filtration and smoke protection.

Our Main Redwood City Services
The two services Redwood City homeowners call about most are air duct cleaning and dryer vent cleaning. Here’s what each job actually involves in this city.
Air Duct Cleaning in Redwood City
In Redwood City, duct cleaning is often triggered by wildfire-smoke residue, a new allergy flare-up, or a pre-sale home inspection on an older property. The mild climate means your system may sit idle for months, letting fine particulates and rodent debris accumulate in return plenums and supply branches. When we clean, we use Rotobrush and Nikro systems plus Abatement Technologies HEPA filtration so what comes off your duct walls doesn’t recirculate into your living room. The full scope covers supply and return runs, registers, and the main trunk line. Air Duct Cleaning in Redwood City has all the details for that service.
Dryer Vent Cleaning in Redwood City
Homes in the older parts of Redwood City often have dryer vents that run through crawlspaces or take long, low-gravity horizontal paths to the exterior, which is exactly where lint packs in and airflow drops. A vent that’s slow to exhaust raises drying times and creates a fire hazard. We clean the full run from dryer transition to the exterior termination, using powered brushes sized to the vent diameter, then verify airflow at the discharge point. If the old foil vent is crushed or separated, we’ll tell you. Dryer Vent Cleaning in Redwood City covers our approach in detail.
Air Duct Repair in Redwood City
Air duct repair in Redwood City is what we do when cleaning reveals the underlying problem: a disconnected return in a Mount Carmel crawlspace, a collapsed flex run in a Redwood Shores attic, or sheet-metal seams that have pulled apart in a 1940s bungalow. These houses run the full range from pre-war metal to mid-century ranch layouts to newer flex duct, and the mild climate hides the damage until a room stops heating or a smell won’t go away. We clean the duct, but we also fix it when it’s broken. We carry the materials to reseal, reconnect, and replace sections on the spot, and our work is covered by the same upfront pricing we use across all services. Air Duct Repair is available across the four Redwood City ZIPs we cover.
HVAC Duct Installation
Signs you need it
You’re adding a return in a room that’s never reached the thermostat setting, or you’ve just remodeled and the old duct layout no longer matches the new walls.
What it costs in Redwood City
Whole-home HVAC duct installation typically runs $4,000 to $9,500 depending on home size, accessibility, and whether the job involves rigid metal or flex duct.
How we do it
We size the runs to the blower’s static pressure, install sealed supply and return branches, hang or support the runs to code, and verify balance at each register.
Air Duct Replacement
Signs you need it
The ducts are original to a pre-1980 home, wrapped in degraded or asbestos-era insulation, or have rusted through in the crawlspace.
What it costs in Redwood City
Replacing all or most of a duct system in Redwood City homes ranges from $3,000 to $8,000, with partial replacements running less.
How we do it
We remove the old material, assess the plenum and takeoffs, fabricate replacement sections, and install with mastic-sealed joints and new hangers.
Ductwork Repair
Signs you need it
You can hear air rushing inside a wall, one room consistently runs colder than the rest of the house, or you’ve seen a duct section sagging in the crawlspace.
What it costs in Redwood City
Targeted ductwork repair jobs in Redwood City typically land between $650 and $2,800 depending on access, the number of failed joints, and whether sections need replacing.
How we do it
We locate the disconnect or damage, refit the connection, seal with mastic and UL-listed tape, and re-wrap insulation where the old material was disturbed.
Duct Replacement
Signs you need it
A flex duct run has collapsed or torn, a return plenum is full of impossible-to-clean debris, or rodent damage has gone beyond patching.
What it costs in Redwood City
A single duct replacement run in Redwood City is usually $650 to $1,600, while multi-run replacement work lands from $1,000 up to $3,000.
How we do it
We remove the failed section, install a correctly sized replacement, seal both ends at the plenum and register, and confirm airflow before we leave.
Ductwork Installation
Signs you need it
You have a new addition, a converted garage, or a remodel that extended the living space beyond the current distribution lines.
What it costs in Redwood City
New ductwork installation for a single room or zone runs $1,000 to $2,700 in Redwood City, depending on run length and ceiling or crawlspace access.
How we do it
We run new sealed supply and return branches from the plenum, install the register boots, and balance the new zone against the existing system.
What Air Duct Repair Costs in Redwood City
| Item | Typical range in Redwood City |

Does repairing ducts make sense before cleaning in Redwood City?
Usually yes. If there’s a disconnected return pulling crawlspace air, cleaning first just means whatever you removed comes right back through the gap. We fix the integrity issue first, then clean.
How do I know whether my Redwood City ducts need repair or just cleaning?
If rooms heat unevenly, you hear airflow where you shouldn’t, or dust returns within weeks, that points to a leak, not accumulation. We can diagnose it during a standard cleaning visit and show you photos.

What Redwood City Customers Say
"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
- Emily Nguyen"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."
- Christine Yang"Job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
