Air Duct Cleaning Company in San Dimas, CA
Most homes in San Dimas were built between the 1960s and 1990s, and many still run on their original sheet-metal or flex duct systems. Those ducts have spent decades pulling hot inland air, Santa Ana grit, and foothill dust through return-air grilles. When we arrive for air duct repair or cleaning in San Dimas, we typically find aging mastic seals, crimped flex runs, and dust intrusion patterns specific to this city’s terrain. The fix usually involves both cleaning and structural repair, which we handle in a single visit. Call (833) 589-9571 for a free estimate.
Why San Dimas Homes Are Different
San Dimas sits at the base of the San Gabriel Mountains, which changes how ductwork behaves here. Each fall, dry Santa Ana winds funnel through the valley and push fine mountain dust and wildfire ash against foothill homes, especially along the northern edge of the city. That grit finds its way into attic vents, return-air plenums, and duct seams. Crews working flatter parts of the basin see far less of this. We have learned to check return-air plenums near garages for wind-driven dust intrusion, and to watch for rodent droppings in ducts of homes backing onto the foothill washes. You just don’t see that in the coastal basin.
The housing stock adds another layer. Most of San Dimas is mid-century to late-20th-century tract housing. Ranch-style and two-story layouts put ductwork in attics and crawlspaces, where summer heat bakes flex duct and dries out mastic seals. Hot inland summers, often in the 90s to 100s, mean HVAC systems run hard from May to October. More runtime means more dust pulled through filters and ducts. By the time a homeowner notices weak airflow or dust on the registers, the ducts usually need more than a quick blow-out.

Our Main San Dimas Services
Two services account for most of the calls we get from San Dimas homeowners: air duct cleaning and dryer vent cleaning. Both have their own detailed pages, linked below.
Air Duct Cleaning in San Dimas
San Dimas homes collect a specific kind of dust: fine, wind-driven particles that settle into duct walls and return-air plenums. Our Air Duct Cleaning in San Dimas service uses the Rotobrush contact-cleaning system, which physically scrubs duct surfaces with rotating brushes rather than just pushing debris around with air pressure. That matters here because Santa Ana dust packs onto sheet metal and will not move with air alone. We pair the contact cleaning with Nikro HEPA negative-air extraction so what the brushes loosen gets pulled out of the home, not recirculated through the vents.
Dryer Vent Cleaning in San Dimas
Lint accumulation is a fire risk wherever dryers run, but San Dimas homes with long vent runs through attics or crawlspaces face a higher accumulation rate. Our Dryer Vent Cleaning in San Dimas service clears the full run from dryer to exterior termination. We treat it as a dedicated fire-prevention job, not an upsell afterthought. In foothill-adjacent homes, vent caps also collect windblown debris and nesting material, which makes annual clearing more important here than in the flatter basin.
Air Duct Repair in San Dimas
Air duct repair in San Dimas usually means fixing what decades of heat, settling, and wind-driven grit have done to aging ductwork. Many of the city’s 1960s and 1970s tract homes still have original galvanized ducts with mastic seals that have dried and cracked. Once a seal fails, conditioned air leaks into the attic or crawlspace, and dust from outside gets pulled into the system. We find the leaks, repair or replace the damaged sections, and when needed, clean the whole system so the fix lasts. For a closer look at this service, see Air Duct Repair.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setting, visible dust around registers even after cleaning, or a sudden spike in your energy bill often point to leaking or disconnected duct sections.
What it costs in San Dimas
Ductwork repair in San Dimas typically runs $450 to $1,800 depending on how many sections need sealing or reconnecting.
How we do it
We locate the failed sections, inspect the surrounding duct for related damage, then seal, reconnect, or replace the affected runs and re-test airflow at each register.
Air Duct Replacement
Signs you need it
Ducts that are crushed, rusted through, or lined with contamination that cleaning cannot safely remove are stronger candidates for replacement than repeated patch repairs.
What it costs in San Dimas
Full air duct replacement in San Dimas typically runs $2,800 to $7,500 depending on home size and duct accessibility.
How we do it
We remove the damaged duct sections, install new properly sized and sealed runs, and verify airflow and static pressure before finishing the job.

Does duct repair require a permit in San Dimas?
Most basic duct sealing and replacement does not require a permit, but any work that touches the HVAC system’s structural or mechanical scope may. We can confirm requirements with the city before work begins.
Can you repair ducts without replacing the whole system?
In most San Dimas homes, yes. We repair the failing sections and leave sound ductwork in place. Replacement is only recommended when the existing runs are too degraded to seal reliably. Call (833) 589-9571 to schedule an inspection.

What San Dimas Customers Say
"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Wade Pruitt"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."
- Gilbert Reyes"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
