Air Duct Cleaning Company in Ontario, CA
Air duct repair in Ontario usually addresses one of two problems: flex duct that was undersized or badly hung in the 1990s-2000s tract build-outs, or metal duct in the 1950s-60s ranch core that has rusted, separated, or been crushed in a crawlspace. The semi-arid climate and Santa Ana wind events push fine grit through systems that were never sealed well in the first place, which turns minor leaks into persistent dust problems. Duct Cleaning Fontana has served Ontario since 2017, and we bring Rotobrush and Nikro equipment to every job. Call (855) 501-3681 for a straight answer on what your system actually needs.
Why Ontario Homes Are Different
Ontario sits in the Chino Basin, where the Santa Ana winds and the I-10 corridor deliver a year-round particulate load that coastal LA homes simply don’t experience. During sustained wind events, we regularly find the return-air plenum and filter slots packed with wind-blown grit and fine sand carried off the open lots and foothills east of the city. That pattern shows up most heavily in homes along the 91761 east side and near the 60/15 freeway corridors.
The housing stock splits the work into two very different jobs. Older mid-century neighborhoods in 91762 and 91764 have metal duct runs that are sixty to seventy years old, often partially retrofitted, with deteriorated seals and disconnected joints hidden inside walls and crawlspaces. The newer two-story production homes clustered toward 91761 use long runs of flex duct with multiple trunk-and-branch splits. That design accumulates settled dust in branches no homeowner ever sees, and after twenty-plus years of near-constant cooling-season runtime, those branches are full.
Hot, dry summers mean the HVAC system runs from late spring through early fall, continuously moving dust, pet dander, and wind-driven grit through the ductwork. Cleaning here is not a maintenance checkbox. It is reclaiming a system from a particulate load that builds faster than anywhere on the coast.

Our Main Ontario Services
The two services Ontario homeowners call about most are whole-system air duct cleaning and dryer vent cleaning, and they are more connected than people expect. Wind-driven grit clogs ducts and dryer vents at the same time, and both jobs benefit from the same professional-grade equipment.
Air Duct Cleaning in Ontario
In Ontario, air duct cleaning means more than running a vacuum through the registers. We use Rotobrush and Nikro rotary brush systems that reach every linear foot of each duct run, including the long, heavily-branched flex duct common in 91761 tract homes. The semi-arid dust load means return-air plenums are often packed with fine sand, and simply changing the filter does nothing for what has already settled downstream. For the full scope of this work in Ontario, see our Air Duct Cleaning in Ontario page.
Dryer Vent Cleaning in Ontario
Dryer vents in Ontario clog faster than homeowners expect because the same fine grit that fills ductwork also coats the inside of the vent run. A dryer that runs hot and slow is the first sign, and it is also a fire-safety issue. We treat dryer vent cleaning as a distinct specialty, not an add-on, and we check the full vent path from the dryer to the exterior termination. Details are on our Dryer Vent Cleaning in Ontario page.
Air Duct Repair in Ontario
Air duct repair in Ontario is where we fix what cleaning alone cannot. In the 91762/91764 core, decades-old metal duct has often separated at the seams or rusted through in sections, and every leak pulls attic or crawlspace air into the living space. In the 91761 tract homes, flex duct that was undersized or badly supported has kinked, torn, or pulled loose from the trunk line. Cleaning those systems without repairing the damage just means the dust comes back within a season. Our full Air Duct Repair service covers the gap generalist HVAC companies leave behind.
HVAC Duct Installation
Signs you need it
Rooms that never reach temperature, visible crushed or collapsed duct in the attic, or a system that was never properly ducted after a renovation all point to new duct installation rather than patching.
What it costs in Ontario
New duct installation in Ontario typically runs $1,500 to $5,000 depending on the number of runs, accessibility, and whether the home is a single-story ranch or a two-story production build.
How we do it
We measure static pressure, map the existing trunk layout, remove the failed sections, and install properly sized and supported duct with sealed connections at every joint.
Air Duct Replacement
Signs you need it
Duct that has rusted through, been crushed by storage in the attic, or shows mold staining from years of condensation is beyond repair and should be replaced outright.
What it costs in Ontario
Replacing an entire duct system in an Ontario home falls between $2,500 and $6,000, with the upper end reflecting two-story 91761 homes with long, branched flex runs.
How we do it
We remove the old duct, inspect the plenum and boots, replace damaged components, and run new duct with proper support and sealed connections throughout.
Ductwork Repair
Signs you need it
Visible gaps at joints, dust streaks around registers, musty air from the vents, or a sudden jump in the electric bill during cooling season all indicate duct leaks that need repair.
What it costs in Ontario
Typical ductwork repair in Ontario costs $350 to $1,500, depending on how many joints need resealing and whether access requires crawling through a tight attic or crawlspace.
How we do it
We locate the failed sections, reconnect separated joints, seal every seam with mastic and UL-rated tape, and confirm the repair by re-testing airflow at the affected registers.
What Air Duct Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Ductwork sealing / minor repair | $350 – $1,500 |
| HVAC duct installation (partial or full) | $1,500 – $5,000 |
| Air duct replacement (full system) | $2,500 – $6,000 |
How do I know if my Ontario home needs duct repair or just cleaning?
If dust returns within weeks of cleaning, or rooms never hold temperature, the problem is structural, not debris. Leaks and disconnections pull unconditioned attic air into the system. Cleaning fixes what is inside the duct; repair fixes the duct itself.
Can you repair sections of duct without replacing the whole system?
Yes. Most Ontario homes only need targeted repair: reconnecting separated joints, sealing leaks, and replacing crushed flex sections. Full replacement is only necessary when the duct is rusted through or so badly installed it cannot be salvaged. Call (855) 501-3681 for an honest assessment.
Brands We Service in Ontario
We work on systems integrated with Honeywell and Aprilaire whole-home air quality products, which means we understand how filtration, airflow, and duct condition interact. We stock common Aprilaire filter replacement sizes and Honeywell bypass components locally, so service calls rarely require a follow-up visit. See our brands for the full list of equipment we service.

In Ontario, the two biggest price drivers are access and system age. Two-story 91761 homes with long flex runs and tight attic hatches take more labor, and systems in older 91762/91764 homes often need sealing work before cleaning is worth doing. We quote one flat price per system before any work starts, so the number you agree to is the number you pay.
Neighborhoods We Serve in Ontario

FAQs About Air Duct Cleaning Company in Ontario
Most Ontario appointments are scheduled within five to seven business days. Homes along the 91761 east side are easy to reach from our Fontana base, and we often batch Ontario jobs on the same day to keep drive time short.
Most duct sealing and repair work does not require a permit in Ontario. Full duct replacement on a new build or major remodel may, but that is handled by the general contractor’s scope. We will tell you plainly if your job falls into either category.
Ontario’s semi-arid climate and Santa Ana winds load HVAC systems with fine sand and grit that coastal homes do not see. The return-air side especially fills with wind-blown particulate from open lots and foothills east of the city, which means cleaning here is about removing a much heavier, finer dust load. Call (855) 501-3681 for a free estimate.

What Ontario Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Dev Sharma"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Ryan Fletcher"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Claudia Vargas
