Air Duct Cleaning Company in Walnut, CA
Air Duct Repair is the service Walnut homeowners end up needing most often, usually after years of dry dust and Santa Ana ash have worked their way through older rigid ductwork and worn it thin. Walnut’s housing stock runs heavy to 1970s – 1990s tract homes with original galvanized trunk-and-branch runs, and those systems leak, separate, and pull attic grit long before anyone thinks to look. We bring commercial-grade Rotobrush and Nikro equipment into those homes and treat the ducts as a system, not a quick vacuum job. Call (855) 382-4830 for a free estimate.
Why Walnut Homes Are Different
Walnut sits at the foothill edge of the San Gabriel Valley, and the local climate does something specific to ductwork. The semi-arid summers bake dust fine, then Santa Ana wind events push it down the San Jose Hills and through return-air grilles. Homes within sight of the Mt. San Antonio College foothill edge collect noticeably more ash and grit after those wind events than flatland tract homes closer to the Valley Boulevard corridor, where ordinary dust and pet hair are the bigger issue. Low humidity means mold is rarely the driver in Walnut. The problem here is dry debris loading, filter saturation, and grit working into duct joints and seams. Built largely through the 1980s – 2000s, many Walnut homes still run original rigid galvanized ductwork with ceiling registers, which means access points matter and cleaning requires tools that can handle real trunk lines rather than flex-duct runs. We work with that housing stock every day.

Our Main Walnut Services
Most Walnut homeowners call us about two things: the ducts themselves and the dryer vent that shares the wall with them. Both jobs need real equipment and both are covered by a dedicated Walnut page if you want the full detail.
Air Duct Cleaning in Walnut
Air duct cleaning in Walnut is about removing what the Santa Anas leave behind. Fine dust, ash, and pet hair pack into return ducts and sit in the trunk lines, then recirculate every time the HVAC kicks on. We clean the full run with Rotobrush and Nikro systems, including the return side where Walnut homes collect the most debris. Read the full breakdown on the Air Duct Cleaning in Walnut page.

Dryer Vent Cleaning in Walnut
Dryer vents are a fire hazard, not a maintenance afterthought. Lint accumulates fast in Walnut’s dry air, and a restricted vent pushes the dryer harder and raises the risk at the exhaust point. We clean the full vent run and restore airflow with a dedicated service, not an upsell. The Dryer Vent Cleaning in Walnut page covers the process and what to look for.

Air Duct Repair in Walnut
Air Duct Repair in Walnut usually means sealing or replacing sections of 1970s – 1990s galvanized ductwork that has separated at the seams, sagged in the attic, or been crushed during a remodel. The dry climate accelerates the problem: joints dry out, tape fails, and decades of Santa Ana dust push through the gaps and into the living space. Cleaning alone can’t fix a leaking duct run, which is why we do the job behind the job. Air Duct Repair is a standalone service for us because the structural cause of contamination matters as much as the contamination itself.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat temperature, a sudden rise in dust, or a musty attic smell coming from the registers point to separated or damaged duct sections.
What it costs in Walnut
Expect to pay $3,500 – $5,000 per month to cool the ducts themselves if there’s a need for more than patching; final pricing is set by the written estimate after we inspect the run to the same level of detail as any well-documented report.
How we do it
We locate the failing sections, seal accessible joints and seams, replace crushed or separated segments, and confirm airflow at each register before we leave.
Air Duct Replacement
Signs you need it
Ducts that have collapsed, rusted through, or become so brittle that repair patches won’t hold mean replacement is the only option that actually solves the problem.
What it costs in Walnut
Typical costs range from $7,900 to $12,000+ depending on the number of runs and whether we’re working in a tight attic or a crawlspace, not on the duct itself.
How we do it
We remove the failed ductwork, install new galvanized trunk and branch runs sized to the system, seal every joint, and balance airflow at the registers.
What Air Duct Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Ductwork repair, patching and sealing | $3,500 – $5,000 per month |
| Air duct replacement, full system | $7,900 – $12,000+ |
| Ductwork installation, new construction | $9,300 – $10,000 |
Will repairing my ducts actually reduce dust in a Walnut home?
Yes, and the reason is specific to Walnut. Most dust entering your living space does not come from the duct surfaces; it comes from leaks in the return side pulling attic air and grit past the filter. Sealing those leaks removes the entry point, so you see less dust immediately after the repair. Call (855) 382-4830 for an exact quote, estimates are free.
How do I know if my Walnut ducts need repair or replacement?
We inspect the system first and show you the condition before we quote. If the duct is separated at seams, repair works. If it is crushed, rusted, or sagging in multiple places, replacement is the only way to fix the problem. The written estimate explains exactly what we found and what each option costs.
Brands We Service in Walnut
We work on duct systems tied to every major HVAC brand, and we install and service Honeywell and Aprilaire filtration systems alongside the cleaning work. If a Walnut home needs a Guardsman or Abatement Technologies setup for containment-grade work, we carry the equipment and know how to run it. See our brands for the full list.

What Walnut Customers Say
"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."
- Lucia Delgado"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."
- Marisol Hernandez"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
