Air Duct Cleaning Company in San Dimas, CA
Air Duct Repair is the first thing we look at when a San Dimas home has persistent dust, weak airflow, or rooms that never hold temperature. The 1960s – 1980s tract homes and older ranch-style houses around the historic downtown were built with rigid metal ductwork that has now seen fifty-plus years of Santa Ana wind events, and the flex duct added piecemeal over the decades sags and separates. We bring Rotobrush and Nikro systems plus Abatement Technologies negative-air equipment to every job, because canyon dust and wildfire ash in San Dimas demand more than a consumer-grade vacuum. Call (855) 382-4830 for a free estimate.
Why San Dimas Homes Are Different
San Dimas sits at the mouth of the San Gabriel Valley, right where the canyons funnel wind and dust. The trade winds that pour through the San Gabriel Mountains come down into town and pack fine particulate silt through every return grille, so duct cleaning here is as much about wind-blown canyon sediment as it is about normal household accumulation. Homes tucked against the foothills along the Bonelli Park edge, the Puddingstone area, and the hillside streets get the worst of it. That mountain-to-valley dust load is not what a technician in neighboring Covina or Glendora sees the same way, and it changes how we approach both cleaning and repair.
The housing stock matters too. Mid-century and 1960s – 1980s single-family tract homes still on original rigid metal ductwork develop pinhole leaks at the seams and joints. The flexible duct replaced piecemeal over the years tends to sag in the attic heat, collecting debris in the low spots. Hot, dry inland summers with persistent Santa Ana events push canyon dust and wildfire ash from the San Gabriels into HVAC systems faster than most homeowners realize, while mild wet winters let moisture settle in attic flex duct. When the Santa Anas blow, technicians pull visibly gray dust and ash out of return registers on the foothill-side streets weeks before anything shows up in flatland homes.

Our Main San Dimas Services
Most San Dimas homeowners call us for one of two reasons: the vents are blowing dust every time the system kicks on, or the dryer takes two cycles to finish a load. Both are handled as dedicated jobs with their own equipment and process, never as an afterthought.
Air Duct Cleaning in San Dimas
We clean the full duct system with Rotobrush and Nikro agitation systems paired with Abatement Technologies negative-air containment. That combination matters in San Dimas because the fine canyon silt and wildfire ash that settles in ducts stays suspended until it is physically agitated and pulled under negative pressure, which is exactly what these machines are built to do. Homes on foothill streets near the Bonelli Park edge often need return-side work prioritized, since that is where wind-driven dust enters first. See the full process on our Air Duct Cleaning in San Dimas page.
Dryer Vent Cleaning in San Dimas
Dryer vents are a fire hazard, not a maintenance afterthought. Lint accumulation in the vent line is a leading cause of residential dryer fires, and in San Dimas the dry inland air lets lint pack down hard inside the duct run rather than staying loose. Older homes near the historic downtown often have long or awkward vent runs that were never cleaned since installation. We treat dryer vent cleaning as its own dedicated service with its own tools and checklist. Details are on our Dryer Vent Cleaning in San Dimas page.
Air Duct Repair in San Dimas
Air duct repair in San Dimas usually means one of two things: sealing the leaks in aging rigid metal ductwork, or replacing flex duct that has sagged and separated in the attic. Homes built in the 1960s through 1980s are at the age where original duct joints fail, and the canyon dust and Santa Ana ash that blows through San Dimas finds every gap and pulls straight into the living space, bypassing the filter entirely. Repair is the job behind the job: cleaning removes what is there, but repair closes the entry points so contamination stops coming back. Our full Air Duct Repair service covers structural fixes that eliminate gaps, leaks, and contamination entry points that cleaning alone cannot address.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setting, visible dust around return grilles, and higher utility bills with no change in usage all point to leaking ductwork.
What it costs in San Dimas
Ductwork repair in San Dimas typically runs $180 – $65 per duct run depending on the size and location of the leak, with attic access and foothill-side homes sometimes pushing toward the upper end.
How we do it
We locate each leak, seal joints and seams with mastic and foil tape rated for HVAC use, and test static pressure before and after to confirm the repair.
Duct Replacement
Signs you need it
Collapsed flex duct, rusted-through metal runs, or ducts so contaminated that cleaning cannot restore them are the situations where replacement is the only honest fix.
What it costs in San Dimas
Duct replacement in San Dimas typically runs $100 – $75 per duct run for materials and labor, with full-system replacements priced by the written estimate after we measure the actual layout.
How we do it
We remove the failed section or entire run, install correctly sized and supported replacement duct, seal every connection, and verify airflow at each register.
What Air Duct Repair Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Ductwork repair (per run) | $180 – $65 per duct run |
| Duct replacement (per run) | $100 – $75 per duct run |
| HVAC duct installation | Quoted per project |
How do I know if my ducts need repair or just cleaning?
Cleaning removes what is inside; repair fixes the structure. If dust returns within weeks of a cleaning, gaps are letting canyon dust and ash back in. Sealing those entry points is the only way to stop the cycle.
Does attic access make duct repair more expensive in San Dimas?
Homes with tight attic access or ducts buried under insulation take longer to work on, which affects the written estimate. Foothill-side homes near the Bonelli Park edge sometimes have shallower attic spaces, but the price is always set before work starts.
Brands We Service in San Dimas
We work on every major residential HVAC brand in San Dimas homes, and we stock common Honeywell, Aprilaire, and Guardsman parts locally so repairs are not delayed waiting on shipments.
