Fast, Reliable Air Duct Cleaning Across San Dimas
Most standard air duct cleanings in San Dimas run between $350 and $650 per system, with larger foothill homes and two-story properties landing closer to the $700 to $950 range if multiple air handlers are involved. That’s the honest answer before you even pick up the phone. We’re Cardinal Air Duct West Covina, led by Omar Haddad, and our Air Duct Cleaning crews know San Dimas attics better than anyone, because we spend our days inside them. Call (424) 688-1845 for a written price before any work begins, and we mean written, not waved at you from across the driveway.
If you live in San Dimas, you already know the drill with home services: vague quotes, long arrival windows, and a technician who suddenly discovers “extras” once the van is parked. We built the Relay Standard to remove all of it. Live trackable arrival time. Before-and-after photos of your actual ducts. A digital invoice you can pay from your phone. No exceptions.
Why Cardinal Air Duct West Covina Is San Dimas’s Preferred Air Duct Cleaning Company
San Dimas homeowners deal with a specific problem: original flexible ducts from the 1970s and 1980s that have been baking in attic heat for four decades. When ambient attic temperatures push past 140°F in summer, that old flex duct insulation turns brittle, cracks, and eventually collapses. Most Dryer Vent Cleaning - San Dimas competitors show up with a brush and a vacuum and never look at what’s behind the drywall. We run a camera inspection first, because in San Dimas the duct problem is usually structural before it’s dirty.
Our technicians are background-checked, uniformed, and they arrive with professional-grade equipment you can name: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. You’ll know your tech’s name before they knock. Reviews from San Dimas customers consistently mention the same three things: the price didn’t change, the photos proved the work, and someone actually answered the phone at 9 p.m. when they called with a question.
Dispatch is coordinated from our Los Angeles office, but crews serve San Dimas locally and know the streets: the tract layouts off Arrow Highway, the two-story builds around Bonita Avenue, the newer foothill estates near Via Verde. Response time to most San Dimas neighborhoods is same-day or next-day, and a live person answers (424) 688-1845 around the clock.
Styles & brands we work with
Commercial Air Duct Cleaning in San Dimas
Commercial Air Duct Cleaning serves San Dimas businesses along Arrow Highway, in the downtown corridor, and in the light industrial pockets near the 57 Freeway. Commercial work means longer runs, larger trunk lines, rooftop units, and a real need for containment that keeps dust out of occupied spaces. A typical commercial cleaning in San Dimas starts around $900 and can run $2,500 or more depending on square footage and the number of rooftop units, with per-system pricing always given in writing before work starts.
Source Removal for Commercial Systems
We clean under negative pressure, meaning every particle we loosen goes into our Nikro HEPA units rather than recirculating through your space. For restaurants, medical offices, and retail storefronts in San Dimas, that means no dust settling back onto counters, equipment, or product. We also provide photo documentation for property managers and lease compliance.
Multi-Tenant and Mixed-Use Properties
San Dimas has a mix of older strip centers and newer mixed-use buildings. Older buildings often have decades of accumulated debris in return plenums and poorly sealed supply runs. We scope each system with a camera before pricing, so if there’s damage behind the walls, you see it on the invoice and the photos before you pay for cleaning.
Air Duct Cleaning Services in San Dimas
Air Duct Cleaning Services for San Dimas homes starts with a camera inspection and a per-system quote. A standard 2,000-square-foot single-system tract home in San Dimas typically runs $350 to $550, while a 2,900-square-foot two-story with three air handlers, like the homes off Bonita Avenue, runs $900 to $1,300 because each system is cleaned and sealed separately. You get one written price per system before anything is touched, and that number doesn’t move when the tech steps into your attic.
Full System Cleaning with Video Inspection
We clean supply ducts, return ducts, plenums, and the blower cabinet. Video inspection happens before cleaning, so we know if a flex run has collapsed, and after cleaning, so you can see the result. If the camera shows structural damage like a kinked or fully collapsed run, we show it to you on the spot and give you a separate, written quote for the repair. You decide. No pressure.
Return and Supply Duct Sealing
Sealing is where most San Dimas homes leak conditioned air. In original 1970s and 1980s builds, the duct joints at registers and plenums were rarely sealed well, and the tape fails with time and heat. We seal those joints as part of any full system cleaning, then run a static pressure check to confirm airflow actually improved. If you have three systems, we do this three times, because a good second-floor clean doesn’t fix a leaky first-floor return.

Trusted Brands We Service in San Dimas
The equipment in San Dimas attics includes Honeywell media cabinets, Aprilaire filters, and Guardsman UV and filtration products. Our techs carry common replacement filters and UV bulbs for these brands on the truck, so if your Aprilaire cabinet needs a fresh MERV 13 filter during a cleaning, it’s done that same visit. For Rotobrush and Nikro, those are the tools we bring, not brands we’re unfamiliar with, and they’re tools chosen because they handle the specific mess of older San Dimas ductwork: collapsed flex, separated joints, and fine dust from Santa Ana winds. No truck-mounted shop-vac shortcuts.
Common Air Duct Cleaning Problems We See in San Dimas Homes
- Collapsed flex ducts in 1970s and 1980s tract homes. Attic temperatures above 140°F cause the inner liner of old flexible ductwork to separate and kink. A brush cleaning doesn’t fix this.
- Disconnected registers in the attic. Heat expansion and decades of vibration separate boots from the sheetrock, so air leaks into the attic instead of your back bedrooms. We find this on at least a third of San Dimas homes we clean.
- Santa Ana wind dust loading on newer foothill homes. Even tight, modern builds near Via Verde pull fine desert dust through outside air intakes and recirculate it through the system. Ducts in newer San Dimas homes need cleaning on a similar schedule as older ones.
- Deteriorated duct insulation. The insulation jacket on original 1980s flex ducts breaks down into fine fibers that circulate through the supply stream. Source removal cleaning under negative pressure removes this material rather than blowing it back into the house.

FAQs About Air Duct Cleaning in San Dimas
A collapsed flex duct will show up as one or two rooms that never cool properly, even after you clean the ducts. Dirty ducts affect air quality; collapsed ducts affect airflow. The only way to know for sure is a camera inspection, which we do before we clean. In the original 1970s tract homes along Arrow Highway and Bonita Avenue, we find collapsed or kinked runs often enough that we won’t clean a home without scoping it first. Call (424) 688-1845 and we’ll bring the camera.
Because each system is its own connected loop of supply and return ductwork, and they all need to be cleaned and sealed separately. A bigger San Dimas home with three air handlers means three blower cabinets, three filter racks, and three sets of supply runs, plus the return plenums. If a company quotes you one flat price and doesn’t mention systems at all, they’re either under-bidding and will make it up elsewhere, or they plan to skip work. We worked a 2,900-square-foot 1980s two-story off Bonita Avenue with three separate HVAC systems. The second-floor air handler was pulling from flex ducts so brittle they had collapsed behind the drywall, dropping static pressure to almost nothing. Our camera inspection found a 14-foot run fully kinked and two others with insulation falling away, so we replaced the collapsed sections, sealed the supply and return joints, and then performed source removal cleaning on all three systems under full negative pressure with HEPA filtration, restoring airflow to the back bedrooms. That’s what per-system pricing protects you against: paying for a clean that never actually happened. Call (424) 688-1845 and we’ll scope each system and quote each one separately.
You should expect photos and video inside your actual ducts, before and after, showing the plenums, the supply runs, and the return. You should also expect a written receipt that itemizes what was cleaned and what wasn’t. In San Dimas, where much of the ductwork is hidden behind drywall in 140°F attics, that documentation is not optional. If a company can’t show you what they did, assume they didn’t do it. Every Cardinal booking includes before-and-after photo proof under The Relay Standard.
Yes. San Dimas sits at the base of the San Gabriel Mountains, and when Santa Ana winds push through the passes, they carry fine dust and ash that get drawn into outside air intakes and recirculated through your ductwork. Homes near the foothills, especially newer developments, see this faster than homes closer to downtown. The fix is not avoiding cleaning; it’s changing filters more often during wind season and making sure your return ductwork is properly sealed. Call (424) 688-1845 if you’re seeing dust on fixtures a week after cleaning.
Yes, if the smell is coming from deteriorating fiberglass insulation inside the ducts. Source removal cleaning under negative pressure removes loose insulation fibers and the dust they carry, which often clears the attic-like smell from original flex ductwork. If the duct liner has physically separated or the insulation is wet from a roof leak, cleaning won’t fix that; the duct needs replacement. We’ll show you photos either way before you pay. Call (424) 688-1845 for a written estimate.
