Fast, Reliable Air Duct Cleaning Across San Dimas
Air duct cleaning in San Dimas costs between $450 and $900 for a typical single-family home, and our crews reach most San Dimas neighborhoods within the hour. We’re Duct Cleaning Pomona, and we’ve been cleaning ducts in San Dimas since 2015. This isn’t a side job for us. San Dimas sits tight against the San Gabriel Mountains, and that foothill location changes what accumulates inside your ductwork. The dry Santa Ana winds each fall push fine mountain dust and ash through attic vents and into return-air grilles, especially in homes along the foothill edges. Older tract homes from the 1960s through 1980s add another layer: original galvanized ductwork with aging mastic seals that leak and collect that windblown grit. Call (833) 589-9571 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why San Dimas Homeowners Call Duct Cleaning Pomona for Air Duct Cleaning
Most of our San Dimas customers come to us after a cheaper service left them wondering what actually got done. A shop vac attached to a register doesn’t clean ducts. It stirs up dust and leaves the walls coated. We take a different approach. Our air duct cleaning team uses the Rotobrush contact-cleaning system, which runs rotating brushes along the duct walls to physically scrub off buildup. Then we attach Nikro HEPA negative-air machines to pull the loosened debris out of the house entirely. That’s the same extraction method used in abatement and remediation work, not a residential afterthought.
We’re based in Pomona, so the drive into San Dimas is short. Fast dispatch from 7am to 7pm means most San Dimas jobs get booked and completed without a long wait. And because we work this area every week, we know what to look for. Homes backing onto the foothill washes have a different set of problems than homes near the 57. We check for both.

Air Duct Cleaning Services in San Dimas
Air Duct Cleaning Services in San Dimas means removing years of accumulated dust, pet hair, construction debris, and sometimes worse from the full length of your supply and return runs. We clean supply ducts, return ducts, the main trunk lines, and the plenums. A typical single-family home in San Dimas runs $450 to $900, depending on square footage, number of registers, and how long it’s been since the last cleaning. Every job includes a video inspection before and after, so you see exactly what we found and what the ducts look like when we’re done.
Supply and Return Duct Cleaning
Supply ducts carry conditioned air into your rooms. Return ducts pull air back to the HVAC unit. Both collect dust, but they collect it differently. Supply ducts get coated with the particles that make it past your filter. Return ducts, especially in San Dimas homes near the foothills, pull in whatever the Santa Ana winds push into the attic or crawlspace. We clean both thoroughly, because cleaning only half the system leaves the other half ready to recirculate dust.

Full System Cleaning with Video Inspection
We don’t ask you to trust a before-and-after photo of a single register. Every full system cleaning includes a camera inspection. We show you what’s inside your ducts before we start, and we show you the result when we finish. If we find a disconnected run, a crimped flex duct, or a bad seal, we tell you. And because we also do air duct repair, we can often fix it on the same visit rather than handing you a report and a second appointment.

HVAC Duct Cleaning in San Dimas
HVAC Duct Cleaning in San Dimas addresses the entire path your air travels, from the return grilles through the plenums, across the coil, and out through every supply register. In a city where summer temperatures routinely hit the 90s and 100s, your system runs hard from May through October. That runtime pulls more dust and airborne grit through the ductwork than a milder climate would. A full HVAC duct cleaning in San Dimas typically costs between $500 and $900 for a standard single-family home, with the estimate confirmed before any work begins.
Plenum and Trunk Line Cleaning
The plenums are the boxes where your ductwork meets the HVAC unit. In San Dimas homes near garages, return-air plenums often show dust intrusion from Santa Ana winds that push grit through garage vents and wall gaps. We pay extra attention to these areas. A coated plenum feeds dust into every room the moment the system turns on, no matter how clean the branch ducts are.
Post-Renovation and Post-Construction Cleaning
Drywall dust, sawdust, and construction debris settle deep in ductwork and resurface for months after a remodel. San Dimas has steady renovation activity in its 1960s – 1990s housing stock, and homeowners who skip duct cleaning after a project often wonder why their house won’t stop being dusty. We flush that debris out with the Rotobrush system and HEPA negative-air extraction, leaving the ducts clean rather than just less dusty.
Trusted Brands We Service in San Dimas
The ductwork we clean is part of a larger air-quality system, and we work alongside the equipment you already have. If your San Dimas home runs a Honeywell or Aprilaire whole-home air cleaner, humidifier, or filter system, our technicians understand how those components interact with the ducts. Abatement Technologies filtration sets the standard we apply to every job, residential or commercial. We don’t treat your ducts as an isolated pipe system. We treat them as the delivery path for the air your family breathes, and that means understanding the IAQ equipment feeding it.

AfterCommon Air Duct Cleaning Problems We See in San Dimas Homes
- Santa Ana wind-driven dust intrusion. The dry fall winds funnel through the foothill canyons and push fine mountain dust into attic vents and wall gaps. Homes along the foothill edges show this more than any flatland property: return-air plenums near garages are the first place we check.
- Failing mastic seals on original sheet-metal ducts. Homes built in the 1960s – 1980s often still have their original galvanized ductwork. The mastic seals dry out, crack, and separate over time. A duct that leaks pulls in attic dust, rodent debris, and insulation particles, then pushes them through the house.
- Crimped or disconnected flex duct runs. Attic installations settle. Flex ducts get pinched, crushed by stored boxes, or separated at the joint by structural movement. This is especially common in ranch-style and two-story tract homes built during San Dimas’s growth decades.
- Rodent droppings in return ducts near foothill washes. Homes backing onto the natural washes attract rodents looking for shelter. They enter through crawlspace gaps, nest near the ductwork, and leave droppings in return runs. This is a problem we see regularly in San Dimas and rarely in the coastal basin.

FAQs About Air Duct Cleaning in San Dimas
The Santa Ana winds push fine dust and ash from the San Gabriel Mountains through attic vents and wall gaps, and much of it ends up in your return-air ductwork. This is visible as a fine gray coating on the inside of return plenums and grilles, and it’s far more common in San Dimas than in the flat parts of the basin. Sealing the duct joints and cleaning the full system is the fix. Call (833) 589-9571 for a free estimate.
Original galvanized ductwork from the 1970s is often still structurally sound, but the mastic seals at the joints have usually dried and cracked by now. That means the ducts leak, pulling attic dust and debris into your air stream. We can clean the ducts and repair or re-seal the failing joints in the same visit. If the ducts are too far gone, we’ll tell you straight and give you a repair scope.
Yes. Homes in San Dimas that back onto the foothill washes have a higher risk of rodent activity in crawlspaces and attics. During our inspection we look for droppings in return ducts and plenums, and if we find them we’ll include specialized cleanup and sealing recommendations. This is not something every duct cleaner checks for. Call (833) 589-9571 to schedule an inspection.
We run the Rotobrush contact-cleaning system through your supply and return ducts to scrub the walls, then attach a Nikro HEPA negative-air machine to pull the loosened debris out of the home. A video inspection before and after shows you the condition of the ducts and the result. The whole job usually takes half a day for a standard single-family home in San Dimas.
Every three to five years is a reasonable interval for most San Dimas homes, but the Santa Ana winds and the older housing stock here argue for checking sooner if you’ve never had a cleaning done. Homes with pets, recent renovation, or occupants with allergies should lean toward every two to three years. If you’re seeing dust on registers within days of cleaning surfaces, it’s time to call. We answer 24/7 at (833) 589-9571.
If your ducts haven’t been cleaned in years and you live in San Dimas, the wind and the mountain dust have already been working against you. Call (833) 589-9571 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
