Our Air Duct Cleaning Services in Ontario
Residential Duct Cleaning
Ontario’s housing stock demands different approaches depending on where you live. In central and western Ontario - zip codes 91762 and 91764 - we regularly clean post-WWII and 1960s-70s tract homes with original sheet-metal main trunks spliced to flex duct from later remodels. These hybrid systems accumulate heavy debris at the splice points, and disconnected joints let conditioned air leak into attics or crawl spaces. Our residential cleaning addresses the full run, from return grille to supply register, with mechanical agitation that breaks loose the dry-packed debris Ontario’s low humidity creates.

Commercial Duct Cleaning
Commercial buildings along Milliken Avenue and near the Ontario International Airport corridor handle higher occupant loads and more frequent HVAC cycling. We clean office parks, retail spaces, and light industrial facilities with the same upfront pricing and camera documentation as our residential work. Most commercial jobs in Ontario are scheduled after hours or on weekends to avoid disrupting operations.

Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, and in Ontario they’re the first place diesel particulate and desert dust show up. We clean every supply branch from the main trunk to the register, using Rotobrush mechanical agitation to dislodge debris that’s packed tight against duct walls. After cleaning, we run a video camera through the full supply system so you see the difference.

Return Duct Cleaning
Return ducts pull air back to the HVAC unit, and they’re often the dirtiest part of the system - especially in Ontario, where outdoor particulate loads are elevated year-round. Return duct cleaning removes the buildup that strains your blower motor and recirculates particles through the home. We inspect returns for leaks that draw unfiltered air from attics or crawl spaces, common in older Ontario homes with settling ductwork.

Full System Cleaning
Our most thorough service. We clean the complete duct network - returns, main trunk, supply branches, and boots - plus the air handler cabinet, blower assembly, and coils if accessible. For Ontario homes near the I-10/I-15 interchange, this is often the right starting point because partial cleaning leaves significant contamination in the system. One honest price covers everything, shown before we start.

Video Inspection
Every job we do in Ontario includes camera inspection before and after cleaning. For homes with hybrid duct systems or suspected rodent intrusion, we can also perform standalone video inspections to locate disconnected joints, collapsed flex sections, or contamination patterns. The footage belongs to you - we provide it so you have a record of what’s inside your ducts.

Trusted Brands We Service in Ontario
We clean and service ductwork connected to all major HVAC brands, and we specify professional-grade equipment from Nikro, Honeywell, and Aprilaire for our own work. These are the same brands serious HVAC contractors use, not consumer-grade tools. For Ontario customers, this means parts and compatible components are readily available, and our technicians are trained on the equipment that actually gets specified in this market. We don’t guess at what your system needs.
Common Air Duct Cleaning Problems We See in Ontario Homes
- Diesel soot infiltration near freight corridors. In the industrial-adjacent residential pockets of 91761 near Francis Street and Vineyard Avenue, we regularly pull duct debris that is visibly grey-black with diesel soot rather than typical tan household dust. The BNSF intermodal yard and constant idling truck traffic on Milliken and Haven Avenues load residential ductwork far faster than in neighboring Upland or Rancho Cucamonga.
- Santa Ana wind dust loading. When Santa Ana events funnel desert dust directly off the Cajon Pass, fine particulate matter pushes through every gap in the home envelope and overwhelms standard HVAC filters. We’ve found supply registers packed with fine dust within weeks of a wind event.
- Disconnected joints in hybrid duct systems. Original sheet-metal trunks spliced with later flex duct develop separation at the connection points, especially in 1960s-70s Ontario tracts. Rodents exploit these gaps, and conditioned air leaks into unconditioned spaces, driving up energy bills.
- Dry-packed debris from low humidity. Ontario’s combination of low humidity and high particulate concentration causes debris to dry-pack tightly against duct walls. Basic vacuum-only cleaning won’t touch it. Mechanical agitation is essential for effective removal here.
Pricing for Air Duct Cleaning in Ontario, CA
We don’t do bait coupons or surprise add-ons. Here’s what air duct cleaning costs in Ontario’s market:
| Service | Typical Range in Ontario |

Factors that affect your specific price: number of supply and return vents, accessibility of the main trunk, whether the home has a crawl space or attic duct run, and the level of contamination. Homes near the I-10/I-15 interchange often require more intensive mechanical agitation due to heavy particulate loading.

FAQs - Air Duct Cleaning in Ontario
The grey-black color is diesel particulate from heavy truck traffic on the I-10/I-15 interchange and the adjacent BNSF intermodal yard. In a 1960s tract home near Francis Street and Vineyard Avenue, we found supply ductwork packed with this material. Our Rotobrush mechanical agitation dislodged the dry-packed debris, and a post-cleaning video inspection confirmed the galvanized main trunk was now clear. If you’re seeing this pattern, your ducts are loading faster than standard household dust would indicate - call (844) 685-6342 for a camera inspection and exact quote.
Homes within a mile of the interchange corridor typically need cleaning every 2-3 years rather than the standard 3-5 year interval. The continuous diesel particulate infiltration loads ducts faster than in inland areas. We recommend annual filter changes with MERV 11 or higher rated media, and a camera inspection every two years to monitor buildup. Call (844) 685-6342 to schedule - estimates are free.
Yes. Santa Ana wind events funnel desert dust off the Cajon Pass directly over Ontario, pushing fine particulate matter through gaps in windows, doors, and the building envelope. Even after the winds subside, that dust remains in the duct system and recirculates. We’ve cleaned supply registers packed with fine dust within two weeks of a major Santa Ana event. If your home seems dustier after wind season, your ducts likely need attention.
We inspect every splice point with a video camera before cleaning. These hybrid systems are common in central and western Ontario, and the connection between original metal and later flex duct is the most failure-prone point. Disconnected joints leak conditioned air, draw in unfiltered attic or crawl space air, and provide entry for rodents. Our full system cleaning includes mechanical agitation at these junctions and documentation of any separation we find.
Ontario sits at the junction of I-10 and I-15, one of the nation’s highest-volume inland freight interchanges, and inside the South Coast Air Basin in chronic federal non-attainment for PM2.5 and ozone. This combination of diesel particulate exposure and elevated background particulate loading creates the most acute residential duct-contamination environment in Southern California. Upland and Rancho Cucamonga don’t have the same freight corridor concentration, and their duct contamination patterns reflect lighter household dust rather than the grey-black soot we regularly find in Ontario. The cleaning techniques are the same, but the intensity and frequency of service required are higher here.
