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.

AfterAir Duct Cleaning in Ontario, CA
Dryer vent cleaning in Ontario runs $89-$189 for a standard single-story home, and the freight-corridor air here makes it a job most homeowners should schedule every 12-18 months. The diesel particulate load from Ontario International Airport and the I-10/I-15 logistics parks settles into dryer exhaust lines faster than in Rancho Cucamonga or Claremont, which means lint traps alone don’t tell the full story. Call (806) 606-6902 for a written quote before any work begins.
Why Ontario Homes Are Different
Ontario sits directly under the South Coast Air Basin’s mountain-trapped smog layer, with the San Gabriel and San Bernardino ranges funneling pollution over the city and holding it there. Add the round-the-clock cargo operations at Ontario International Airport, one of the busiest freight airports in the US by tonnage, plus the Amazon, FedEx, and UPS distribution centers lining Vineyard Avenue and Haven Avenue, and you get duct debris with a dark, greasy diesel-soot character you won’t see in neighboring cities.
The housing stock compounds the problem. Central and southern Ontario is dominated by 1970s-1990s tract homes, many still running original fiberglass flex-duct systems now 30-45 years old. Those ducts weren’t sealed to today’s standards, and the liner material degrades over time, creating pockets where diesel particulate and Mojave Desert dust collect. Closer to downtown, post-war homes from the 1940s-1960s often have rigid sheet-metal ductwork with original sealing tape that may contain asbestos, which means assessment has to happen before any cleaning starts. Summer temperatures past 105°F push central air to run nearly nonstop from June through September, and fall Santa Ana winds blast fine desert particulates through every leaky connection. The accumulation cycle never really stops.
Our Main Ontario Services
Two services account for most of the calls we get from Ontario homeowners, and both are direct responses to what the local air and housing stock put into residential ductwork.
Air Duct Cleaning in Ontario
Full-system air duct cleaning in Ontario addresses the diesel soot, industrial dust, and desert particulate that layer inside duct runs across the city. Older flex-duct systems in 1970s-1990s tract homes are particularly prone to holding debris at elbows and plenum connections, and our camera inspection documents what’s actually there before a single panel comes off. See Air Duct Cleaning in Ontario for the full breakdown on process, pricing, and what the documented photo record includes.
HVAC Cleaning in Ontario
HVAC cleaning in Ontario goes beyond the ducts themselves to the blower motor, evaporator coil, and condensate drain pan, all of which collect the same freight-corridor particulate that settles in the ductwork. Homes near the airport and logistics corridors often show visibly darker coil buildup inside two years of the last service. Read the specifics at HVAC Cleaning in Ontario, including what a coil pull-and-clean actually involves and what it costs in this market.

BeforeAfterDryer Vent Cleaning in Ontario
Dryer vent cleaning in Ontario is a safety issue first and an efficiency issue second. Homes in the 1970s-1990s tract developments across central and southern Ontario often have dryer exhaust runs of 15-30 feet with multiple elbows, and the diesel particulate in the air here accelerates lint accumulation inside those runs faster than the coastal markets see. A dryer that’s taking 45 minutes to dry a normal load is often venting against a lint restriction that the camera will show you before and after we clear it. Our Dryer Vent Cleaning service includes a documented photo record of every run we touch, and the written price comes before any work starts.
Dryer Vent Inspection
Signs you need it
Clothes coming out damp after a full cycle, a burning smell while the dryer runs, or a visible lint buildup at the exterior vent hood are the three most common indicators in Ontario homes.
What it costs in Ontario
A standalone dryer vent inspection in Ontario runs $49-$99, and the camera footage we capture is included in the written record we hand over either way.
How we do it
We disconnect the dryer, run a camera through the full exhaust run from the appliance to the exterior termination, and document every obstruction, kink, or disconnection with still images and footage.
Lint Removal
Signs you need it
The dryer takes more than one cycle to dry a standard load, the exterior vent flap barely opens while the dryer runs, or you’re cleaning the lint screen and seeing it refill within a single load.
What it costs in Ontario
Full lint removal in Ontario runs $89-$189 depending on run length and access, and the price is written before we start.
How we do it
We run a rotary brush through the full exhaust line with negative-pressure extraction at the dryer connection, so the lint comes out into our collection canister, not into the laundry room.
What Dryer Vent Cleaning Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Dryer vent inspection | $49-$99 |
| Standard lint removal | $89-$189 |
| Bird guard installation | $69-$139 |
Run length and access are the two biggest cost variables in Ontario. A second-story laundry room with a 30-foot run through a finished ceiling costs more than a ground-floor laundry against an exterior wall. Every quote is written before work starts, and the price doesn’t change once we’re on site.
How often should dryer vents be cleaned in Ontario?
Every 12-18 months for most Ontario homes. The diesel particulate in freight-corridor air accelerates lint accumulation, and 1970s-1990s tract homes with longer, multi-elbow exhaust runs clog faster. Homes near the airport or I-10 logistics parks may need annual cleaning. Call (806) 606-6902 for a written quote.
Why does my dryer vent keep clogging so fast in Ontario?
The combination of freight-corridor diesel soot and Mojave Desert dust creates a heavier, stickier lint matrix than coastal markets see. Older flex-duct exhaust runs with multiple elbows create more collection points. We document the buildup with camera footage so you can see exactly what’s accumulating. Call (806) 606-6902 for an inspection.
Duct Repair & Sealing in Ontario
Duct repair and sealing in Ontario is a direct response to housing stock that’s 30-45 years old in most of the city. Flex-duct liner breaks down, sheet-metal seams in post-war homes near downtown pull apart, and Santa Ana wind events push dust through every gap. Our Duct Repair & Sealing work starts with a camera inspection that pinpoints exactly where the air is escaping, and the written price includes the repair, the sealing, and the photo record of what changed.
Duct Sealing
Signs you need it
Rooms consistently run 5-10 degrees warmer than the thermostat setting, or you can see dust streaking around the edges of supply registers even after a full cleaning.
What it costs in Ontario
Duct sealing in Ontario runs $399-$1,199 depending on the number of accessible runs and the sealing method required, with the full system price written before work begins.
How we do it
We locate every gap, crack, and disconnection with a pressure test and camera pass, then apply mastic or aluminum tape per the manufacturer’s spec and document every sealed connection with before-and-after photos.
Flex Duct Repair
Signs you need it
You can see sagging flexible duct runs in the attic, or the camera inspection shows interior liner deterioration and collapsed sections in a home that still has original 1970s-1990s flex-duct.
What it costs in Ontario
Flex duct repair or replacement in Ontario runs $125-$350 per run depending on diameter, length, and attic access, with the full scope itemized in the written quote.
How we do it
We measure the existing run, match the diameter and R-value, install the replacement section with proper hangers and sealed connections, and photograph the completed work at every joint.
What Duct Repair & Sealing Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Duct sealing (full system) | $399-$1,199 |
| Flex duct repair/replacement | $125-$350 per run |
| Duct insulation | $1.50-$3.50 per sq ft |
Attic height and accessibility drive most cost variation in Ontario. Post-war homes near downtown often have low-slope attics that are harder to work in, and that’s reflected in the written quote before anyone picks up a tool.
Do I need a permit to repair ductwork in Ontario?
Most duct repair and sealing work on existing systems does not require a permit in Ontario, but any modification that changes the HVAC system layout may. We identify the scope clearly in the written quote and flag anything that needs city review before work starts. Call (806) 606-6902 for specifics on your system.
How much air is my ductwork actually losing in Ontario?
The Department of Energy puts typical duct leakage at 20-30% of conditioned air, and older Ontario flex-duct systems from the 1970s-1990s often run at the high end of that range. Our pressure testing and camera documentation show you exactly where the loss is. Call (806) 606-6902 for a written assessment.
Air Quality & Sanitizing in Ontario
Air quality and sanitizing in Ontario is a response to what the South Coast Air Basin puts into the air column every day. Diesel particulate from the freight corridors, dust from Mojave Desert wind events, and the occasional wildfire smoke intrusion layer inside duct systems and settle on coils, registers, and interior surfaces. Our Air Quality & Sanitizing work follows the mechanical cleaning with targeted treatment, documented with the same photo record as every other job.
Mold Treatment
Signs you need it
Musty odor from the supply registers that gets stronger when the AC runs, or visible dark growth on the interior of the plenum or around the supply grilles.
What it costs in Ontario
Mold treatment for duct interiors in Ontario runs $300-$850 depending on the affected area and treatment method, with the written quote specifying the antimicrobial product, dwell time, and re-inspection schedule.
How we do it
We photograph the affected area, apply EPA-registered antimicrobial to the duct interior and accessible plenum surfaces per manufacturer’s instructions, and document the treated area before and after.
Odor Removal
Signs you need it
Persistent food, pet, or smoke odors that return after the ducts have been cleaned and the filters replaced, or a stale smell that concentrates in certain rooms.
What it costs in Ontario
Duct odor removal in Ontario runs $225-$550 depending on the source and whether the treatment is a dry fog application, a surface treatment, or both.
How we do it
We identify the odor source with the camera inspection, then apply the appropriate neutralization method and verify the result with a follow-up air sample or sensor reading documented in the job record.
What Air Quality & Sanitizing Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Mold treatment | $300-$850 |
| Odor removal | $225-$550 |
| UV light installation | $400-$1,100 |
The kind of particulate Ontario’s air puts into ductwork means sanitizing work here often follows a cleaning rather than replacing it. The written price covers the full scope, and every step is documented.
Will sanitizing fix the diesel smell coming from my vents in Ontario?
Sanitizing alone won’t fix a persistent odor source. The diesel particulate has to be physically removed from the ductwork first, then the sanitizing treatment addresses what remains on surfaces. Our process does both, and the photo record shows the difference. Call (806) 606-6902 for a written quote.
Is your antimicrobial treatment safe for my family?
We use EPA-registered products applied per manufacturer’s instructions, with dwell times specified in the written quote and re-entry guidance documented before we leave. Every treatment is recorded with the product name, application area, and photos. Call (806) 606-6902 with any specific concerns.
