Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

What sets Ontario apart from Rancho Cucamonga or Chino isn’t the housing stock. It’s what’s inside the ducts. We’ll get to that. First, the basics: we’re the Air Duct Cleaning team that shows you the inside of your ductwork on camera before we ask you to spend a dollar, and we stand behind the result in writing for a full year.
Why CleanRun Air Duct Cleaning Is Ontario’s Preferred Air Duct Cleaning Company
We’ve worked in enough Ontario homes to know what the freight corridors do to a return duct. Homes along Vineyard Avenue, Haven Avenue, and the I-10 corridor accumulate a dark, greasy film inside their duct liners that you simply don’t see in Claremont or Upland. It’s diesel soot from the thousands of semi-trucks cycling through Ontario’s logistics parks every day, plus the mountain-trapped smog layer that sits over the South Coast Air Basin. Many Ontario homeowners don’t realize their HVAC system is circulating that material until we put a camera inside and show them.
CleanRun was founded in 2013 and has since done more than 52,000 duct cleaning jobs across Southern California. Every one of them started the same way: a written price, delivered before work began. That’s Haven Standard Clause 1, and it’s not a marketing line. Tomas Reyes built this company on the idea that a homeowner should see the price in writing before the van door opens. The 365-Day Done Right Promise backs every job we do in Ontario. If the work isn’t right, we make it right. In writing, on every invoice, not subject to manager approval.
We also bring a Free Second Opinion on any written estimate you’ve received from another company. Bring us a competitor’s quote and we’ll put our number next to it. You’ll see what source removal actually costs versus what a fogging-only quote leaves out.
Our Air Duct Cleaning Services in Ontario

Residential Duct Cleaning
A full residential duct cleaning in Ontario starts with a video inspection of the supply and return runs, the plenum, and the air handler. In a 1980s tract home off Vineyard Avenue, our tech pulled a return duct register and found a black, oily film coating the fiberglass flex-duct walls. That’s diesel soot from the nearby warehouse corridor, and it’s what we mean when we say Ontario ducts need a different approach than coastal or desert markets. Source removal is the standard, not the upgrade.

Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms. In Ontario, they’re also the path that diesel particulate and Mojave Desert dust take into your living space. We run professional-grade negative-pressure extraction equipment from brands like Rotobrush and Abatement Technologies, with mechanical agitation on every supply run to break the bond between debris and the duct liner. A visual-only sweep won’t do it here.

Return Duct Cleaning
Return ducts pull air back to the HVAC system. In Ontario’s older post-war homes near downtown, many return ducts are rigid sheet metal from the 1940s through 1960s, often with original duct-sealing tape. That tape can contain asbestos. We inspect before we agitate, because the last thing you want is fiber release into the air stream. In the 1970s-1990s tract homes that dominate central and southern Ontario, return ducts are typically fiberglass flex-duct that’s now 30-45 years old, with degraded liners that trap debris aggressively.

Full System Cleaning
Full system cleaning means every supply run, every return run, the plenum, the blower motor, and the air handler. Skipping the air handler and blower motor while cleaning only the visible registers is a common failure mode in Ontario. The diesel soot that accumulates on the blower wheel and inside the air handler cabinet simply recirculates through the entire home when the system runs. We photograph the air handler before and after as part of our documented photo record on every visit.

Video Inspection
Every CleanRun job in Ontario begins with a video inspection. You see the inside of your ducts on screen before any work starts, and you see the same runs on screen when we’re done. That’s the Documented Photo Record, a standard deliverable on every visit, not an add-on. If a competitor has told you that your ducts are dirty without showing you, ask why.

AfterTrusted Brands We Service in Ontario
We work on duct systems tied to every major furnace and air handler brand found in Ontario homes, including Carrier, Lennox, Trane, Rheem, and Goodman. We also stock common replacement components for Guardsman and Aprilaire filtration systems, so when we find a collapsed flex run or a failed filter housing during a cleaning in Ontario, we can often repair it on the same visit rather than scheduling a follow-up. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. You can look up any of those brands independently before agreeing to a price.
Common Air Duct Cleaning Problems We See in Ontario Homes

- Diesel soot layering on fiberglass flex-duct liners. Ontario’s position as the Inland Empire’s freight hub means homes near the I-10, I-15, and Ontario International Airport accumulate a dark, greasy debris film that neighboring Rancho Cucamonga or Chino homes don’t see. Standard brush-and-vacuum cleaning without mechanical agitation leaves this material in place.
- Degraded fiberglass flex-duct from the 1970s-1990s. The majority of Ontario’s tract homes in the central and southern portions of the city retain original flex systems now 30-45 years old. Interior liner deterioration creates pockets where debris accumulates and where cleaning must be done carefully to avoid further damage.
- Asbestos-containing duct tape in pre-1970 homes. Ontario’s older neighborhoods near downtown include post-war homes with rigid sheet-metal ductwork. Original sealing tape from that era may contain asbestos, and agitation without assessment can release fibers. We inspect first.
- Leaky duct connections pulling in Santa Ana dust and wildfire smoke. Ontario’s inland location means summer temperatures over 105°F push central air systems to run nearly continuously from June through September, accelerating dust loading. Fall and winter Santa Ana winds then blast Mojave Desert fine particulates and, increasingly, wildfire smoke through any leaky connections, creating a compounding year-round accumulation cycle.
Pricing for Air Duct Cleaning in Ontario, CA
A typical residential full system cleaning in Ontario runs $450-$900 depending on square footage, number of returns, and system accessibility. Supply duct cleaning alone runs $250-$450.

FAQs - Air Duct Cleaning in Ontario

Ontario sits at the convergence of the I-10 and I-15 freight corridors and Ontario International Airport, one of the busiest cargo airports in the US by tonnage. The diesel particulate matter from thousands of daily semi-truck movements settles into HVAC systems as a dark, oily film, especially near Vineyard Avenue, Haven Avenue, and other logistics corridors. Chino and Rancho Cucamonga see more of the tan, sandy Mojave Desert dust, which behaves differently in a duct system. The diesel film bonds to duct liners and blower wheels, which means mechanical agitation and negative-pressure extraction are required to remove it, not just vacuuming. Call (806) 606-6902 and we’ll show you exactly what’s inside your ducts on camera.
Ontario’s humidity is moderate, but when marine layer moisture pushes inland from the coast during spring and early summer, it can create condensation inside duct runs where cool air meets warm attic air. That moisture, combined with the organic debris diesel soot carries, creates conditions for microbial growth in duct liners that drier inland markets like Palm Springs or Victorville don’t experience the same way. A fogging sanitizer without source removal doesn’t solve this, because the growth remains trapped in the liner. Source removal is what actually helps. Call (806) 606-6902 for a video inspection and written quote.
Check the age and condition of your flex-duct runs. Most 1970s-1990s tract homes in Ontario still have original fiberglass flex-duct that’s now 30-45 years old, with interior liners that may be degrading, collapsed, or torn. If your flex runs are original and damaged, cleaning alone won’t fix the problem. Ask any company you’re considering whether they inspect for duct integrity issues before cleaning, and whether they’ll photograph what they find. We do both as standard. Call (806) 606-6902 for a written quote.
Most Ontario homes should have their ducts cleaned every 2-4 years, which is more frequent than the 3-5 year baseline recommended for less particulate-heavy markets. Homes within a mile of the I-10, I-15, or Ontario International Airport, or along the Vineyard Avenue and Haven Avenue freight corridors, may need cleaning every 2-3 years because diesel soot loading accelerates significantly in those areas. If you can see a dark film on your return registers, it’s time. Call (806) 606-6902 and we’ll inspect before we recommend anything.
No, not as a standalone service. A fogging sanitizer without source removal leaves the diesel soot and organic debris in place, and the microbial growth stays trapped in the duct liner. The fog treats what’s on the surface at the moment it’s applied, and then the system recirculates the same contaminated air. Source removal, which is what CleanRun does, physically removes the debris and growth from the duct liner using negative-pressure extraction, mechanical agitation, and HEPA filtration. That’s the difference between a chemical air freshener and actual cleaning. Call (806) 606-6902 for a quote that shows line by line what you’re paying for.
If you’re in Ontario and you want a duct cleaning company that shows you the inside of your ducts before and after, puts a written price in your hand before work starts, and backs the result in writing for 365 days, call (806) 606-6902. Tomas Reyes and the CleanRun team serve Ontario directly from the Inland Empire office, and every job ends with a documented photo record you keep.
