Air Duct Cleaning Company in Walnut Creek, CA
Air duct repair in Walnut Creek means something specific: reconnecting and sealing the long, flexible-duct runs inside 1960s-1990s two-story homes that overheat every summer and pull wildfire smoke every fall. We don’t just clean what’s dirty. We fix what’s leaking, disconnected, or crushed, because a duct system that’s pulling attic air into your living space cancels out every other improvement you make. Call (855) 382-9257 and we’ll walk through what your system actually needs.
Why Walnut Creek Homes Are Different
Walnut Creek sits in the Diablo Valley, where summer afternoons cross 100°F and the cooling system runs for months without a real break. That’s hard on ductwork, especially in the larger two-story homes spread through the hillside neighborhoods of 94595 and 94598, where long flexible-duct runs snake through hot attics and pull air across the full length of the house. Long runs mean more joints, more sag, more places where a duct can separate or collapse without anyone noticing from the living room.
The defining challenge here, though, is wildfire smoke. When September through November offshore winds push smoke from Sierra foothill fires into the valley, it settles against the Diablo foothills and gets pulled directly into return-air grilles. Homeowners in the hillside ZIP codes wake up to a fine layer of ash on window sills and a smoke odor that won’t leave the HVAC system. That’s the call we get every fall: the furnace is technically working, but everything coming out of the vents smells like a campfire. A simple cleaning won’t always solve it. If the smoke odor lingers because ducts are torn and pulling attic air, repair comes first.

Our Main Walnut Creek Services
Two services account for most of the calls we take from Walnut Creek homeowners: the full-system Air Duct Cleaning in Walnut Creek work that handles post-smoke-event restoration, and the Dryer Vent Cleaning in Walnut Creek that clears built-up lint from laundry exhaust lines. Here’s what each one involves in this city.
Air Duct Cleaning in Walnut Creek
Cleaning here often has a seasonal trigger. A homeowner runs the AC hard all summer, then the Diablo winds push smoke into the valley in fall, and suddenly the system is recirculating ash and odor. We run Rotobrush rotary agitation through the supply and return ducts, with Nikro HEPA-rated extraction pulling loosened debris out rather than letting it resettle. Abatement Technologies negative-pressure containment keeps whatever we dislodge from drifting back into living spaces. For the two-story hillside homes, that means long flexible-duct runs get cleaned along their full length, not just at the registers. Full details are on our Air Duct Cleaning in Walnut Creek page.
Dryer Vent Cleaning in Walnut Creek
Dryer vents here run through walls and crawl spaces in older hillside homes, which means lint accumulates in sections no one can see from the laundry room. That’s a fire risk, not a nuisance. We treat dryer vent cleaning as safety maintenance: clearing the entire run from dryer to exterior termination, checking airflow, and confirming the vent actually exhausts outside. This matters in Walnut Creek’s split housing stock, where some condos and townhomes share vent paths through common walls. See the dedicated Dryer Vent Cleaning in Walnut Creek page for the full scope.
Air Duct Repair in Walnut Creek
Air duct repair in Walnut Creek usually comes down to one of two problems: ducts that have separated at the joints after decades of thermal expansion in a hot attic, or flexible runs that have sagged and collapsed under their own weight in the long hillside homes built between the 1960s and 1990s. When the Diablo wind season pushes smoke and ash into those same attic spaces, any gap or tear in the ductwork becomes an entry point for whatever’s up there. That’s why we treat repair as the first step, not a follow-up: a cleaned duct that’s still leaking into the attic just refills with contaminants. It’s also why we handle Air Duct Repair as its own discipline, not an add-on to a cleaning visit. You don’t need two companies for this. The duct system is one system.
Ductwork Repair
Signs you need it
Rooms that never cool properly in summer, visible dust around return grilles even after changing filters, or a smoke odor that returns within weeks of a cleaning all point to duct leaks.
What it costs in Walnut Creek
Ductwork repair in Walnut Creek typically runs $350 to $900 depending on the number of access points and how much of the run has separated or torn.
How we do it
We locate every leak or separation, reconnect and reseal the joints using mastic and metal-backed tape, and test the static pressure before and after so the repair is verified, not assumed.
Air Duct Replacement
Signs you need it
Ducts that are crushed, torn beyond patching, or original to a 1960s home and coated in years of embedded dust and smoke residue need replacement rather than another cleaning.
What it costs in Walnut Creek
Partial air duct replacement in Walnut Creek ranges from $1,500 to $3,200, while a full-system replacement in a large two-story hillside home runs $3,000 to $7,500.
How we do it
We remove the failed sections, install new flexible or rigid duct sized to the system’s airflow requirements, seal every connection, and leave the new runs supported so they don’t sag like the originals.
HVAC Duct Installation
Signs you need it
New additions, converted garages, or systems where the previous installer left undersized, kinked runs that choke airflow and shorten equipment life.
What it costs in Walnut Creek
Duct installation for a new zone or addition in Walnut Creek typically runs $800 to $2,000 for a small run, with full-system installation from $3,000 to $7,500 depending on home size and access.
How we do it
We size the duct to the room’s load, route it for the shortest practical run, seal all joints with mastic, and support the run so it holds its shape from day one.
Duct Replacement
Signs you need it
Insulation breaking down, visible mold or pest intrusion in the ducts, or a system that predates current efficiency standards and leaks more than it delivers.
What it costs in Walnut Creek
Cost of duct replacement in Walnut Creek falls between $3,000 and $7,500 for an average two-story home, with the higher end reflecting long hillside runs and attic access difficulty.
How we do it
We remove the old runs, inspect the plenum and register boxes, install new duct with proper insulation and support, and balance the system once it’s all sealed.
What Air Duct Repair Costs in Walnut Creek
| Item | Typical range in Walnut Creek |
|---|---|
| Ductwork repair (leaks, separations, sagging) | $350 – $900 |
| Partial duct replacement | $1,500 – $3,200 |
| Full-system duct replacement or installation | $3,000 – $7,500 |
How do I know if my ducts need repair or just cleaning?
A cleaning removes what’s inside the ducts; repair fixes what’s wrong with the ducts themselves. If rooms stay dusty, some vents blow weak, or the smoke smell returns within weeks, you have a leak or separation, not a cleaning problem. Call (855) 382-9257 and we’ll test and tell you which one it is.
Can you repair ducts in a two-story Walnut Creek home without opening walls?
In most hillside homes, yes. We access ducts through existing registers, attic hatches, and crawl spaces. Wall demolition is almost never needed. The estimate will show every access point before work starts, so you’ll know exactly what’s involved.
Brands We Service in Walnut Creek
We work with the air-quality equipment already installed in Walnut Creek homes, including Honeywell, Guardsman, and Aprilaire filtration systems. When a clogged or damaged duct is limiting what your filter can do, we fix the duct side so the whole system works as designed. See our brands for the full list.
