Air Duct Cleaning Company in Walnut, CA
Air duct repair in Walnut usually means fixing flex duct that’s been compromised by attic heat, rodents, or age. Most homes here were built in the 1980s and 1990s, and the original duct runs through attics that regularly pass 120°F in summer. We start by locating the failure, then repair or replace the section so the system stops pulling dust and losing conditioned air. Call (877) 600-3906 for a free estimate.
Why Walnut Homes Are Different
Walnut’s housing stock is dominated by 1980s and 1990s Mediterranean-style two-story tract homes in planned communities like Walnut Valley and Snow Creek. These homes share a common layout: stucco exteriors, tile roofs, and flex duct run through attic chases or soffits, often strapped directly to roof sheathing. That’s a problem because Walnut’s inland San Gabriel Valley summers push attic temperatures well above 120°F, which breaks down the plastic outer jacket and inner liner of flex duct over time. When Santa Ana winds kick up, fine dust and pollen get pulled into return leaks and settle through the system. A routine duct cleaning in these attics often reveals torn insulation long before the homeowner notices a cooling loss.
HOA consistency matters here too. Walnut’s planned developments keep tight architectural standards, which means visible exterior changes are restricted. Duct work inside attics and chases stays out of sight, but it still has to be done cleanly and correctly because neighbors share wall lines and roof planes in some tracts. We work with homeowners to route repairs and replacements through existing chases whenever possible, keeping the system functional without disturbing the home’s exterior.

Our Main Walnut Services
Most Walnut homeowners call us for one of two reasons: the air system is pushing dust into the house, or the dryer vent hasn’t been cleaned in years. Both are covered below, and each has its own dedicated Walnut page.
Air Duct Cleaning in Walnut
In Walnut’s two-story tract homes, the duct run from the first-floor return to the second-floor bedrooms can stretch 40 feet or more through hot attic space. Dust, skin cells, pet hair, and construction debris settle along that entire length. We run a Rotobrush rotary system through every reachable run, agitating the duct walls while a HEPA-filtered vacuum pulls debris out at the source. Houses near the 60 Freeway or Grand Avenue corridors tend to collect more fine particulate, so those systems often show heavier buildup. Here’s the full breakdown of air duct cleaning in Walnut.
Dryer Vent Cleaning in Walnut
Laundry rooms in Walnut’s 1980s and 1990s homes are usually on the second floor, which means the dryer vent often runs 15 to 25 feet through a wall or attic before it exits. Lint accumulates fast in those long runs, and that lint is a fire fuel. We treat dryer vent cleaning as a fire-safety service first: we remove the clog, inspect the full run for gaps or disconnects, and verify proper outdoor termination. This is not an add-on. Read the details on Dryer Vent Cleaning in Walnut.
Air Duct Repair in Walnut
Air duct repair in Walnut usually means one of two things: a torn flex duct in a hot attic, or a disconnected joint where the duct meets a register boot. Homes built in the 1980s and 1990s have flex duct that’s now 30 to 40 years old, and the outer jacket fails first. Once it splits, the inner liner sags and leaks, which pulls attic air, insulation fibers, and rodent droppings into the breathing air. Santa Ana wind events push additional dust and pollen through those leaks, so post-wind repair calls are a seasonal pattern here. We repair ducts, not just clean them. That’s the difference between treating a symptom and fixing the air system. Our full Air Duct Repair service page has more detail.
Ductwork Repair
Signs you need it
Rooms that stay warm no matter how low the thermostat goes, a sudden spike in dust, or visible drooping flex duct in the attic are all signs of failed ductwork.
What it costs in Walnut
Targeted ductwork repair in Walnut typically runs $180 to $450 per section, depending on access through attic chases and whether rodent damage is involved.
How we do it
We locate the leak with a pressure test or visual inspection, cut out the damaged section, seal the joint with mastic, and re-insulate around the repair.
Air Duct Replacement
Signs you need it
When the inner liner of flex duct has torn along multiple runs, or the duct is more than 25 years old and crush-damaged, replacement beats repeated patching.
What it costs in Walnut
A full air duct replacement in Walnut’s two-story homes typically ranges from $2,500 to $6,500, based on total duct length and whether second-story access requires extra attic work.
How we do it
We remove the old flex duct, assess the register boots and plenum connections, install new R-6 or R-8 insulated duct in the existing chases, and re-seal every joint before testing airflow.
What Air Duct Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Ductwork repair (per section) | $180 – $450 |
| Air duct replacement (full system) | $2,500 – $6,500 |
| Ductwork installation (new run) | $800 – $2,200 |
Access is the biggest price driver in Walnut. Second-story duct runs through tight attic chases take longer to reach, especially when tile roofs limit attic entry points. We give one flat price per system before work starts, so there are no surprises after the technician arrives.
How do I know my ducts need repair rather than cleaning?
If you see dust blowing from registers after a recent cleaning, hear whistling at register connections, or find rooms that never reach the same temperature as others, the duct itself likely has a leak or a disconnect. Cleaning can’t fix a structural air loss.
Does HOA approval matter for attic duct work in Walnut?
Attic and interior chase duct work does not require HOA approval in Walnut because it’s not visible from the exterior. We keep all replacements inside existing chases, so rooflines and stucco stay untouched. If a project requires an exterior vent change, we flag it before work starts.
Brands We Service in Walnut
We work with equipment and filtration from our brands including Nikro, Honeywell, and Aprilaire for whole-home air quality integration. Most parts we need for these systems are stocked locally or sourced within a day, so Walnut jobs aren’t stalled waiting on filters or controls.

What Walnut Customers Say
"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Colleen Meyer"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."
- Marisol Herrera"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."
