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.

AfterFast, Reliable Air Duct Cleaning Across Ontario
Air duct cleaning in Ontario, CA typically runs $350 – $650 for a residential system and $800 – $2,500 for commercial jobs, with most homes completed in a single visit. Our crews dispatch from the Inland Empire office and cover Ontario neighborhoods from the older tracts south of Holt Blvd to the newer subdivisions near the Ontario Mills corridor. If your home has multiple HVAC systems, we’ll quote each one separately so you know the full scope before we start. Call (361) 326-5060 for a free written estimate.
Ontario’s housing stock splits into two distinct worlds: post-WWII slab-foundation homes with original 1950s – 1970s ductwork, and 1980s – 2000s two-story builds with attic flex runs. We’ve cleaned both for years, and the approach is never the same. Our Air Duct Cleaning team brings Rotobrush rotary systems and Nikro negative-air machines to every job, backed by the 365-Day Done Right Promise in writing.
Why Hollis Air Duct Cleaning Is Ontario’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Inland Empire crews have built a reputation in Ontario by showing up inside the quoted window, pricing in writing before touching equipment, and leaving the site clean. The Garrison Standard isn’t a slogan; it’s a checklist we run on every job.
Our technicians are background-checked and uniformed. You know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, seven days a week, no voicemail loops or callback queues.
The 365-Day Done Right Promise covers every Ontario job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no fine print.
We know Ontario’s specific problems. In the older tracts around downtown and south of Holt Blvd, we routinely find original 1950s – 60s round metal ductwork that was never wrapped or sealed, so attic dust and insulation fibers get pulled straight into the supply stream whenever the blower runs. That problem is virtually nonexistent in the newer east-side subdivisions where attic-run flex duct is at least initially sealed at the plenums. This makes pre-1970 slab-foundation homes here a different job than the 1980s – 2000s two-story houses on the east side. We price and scope accordingly.
Residential Air Duct Cleaning in Ontario
Residential Air Duct Cleaning in Ontario means source removal from your entire forced-air system: supply trunks, return plenums, branch lines, registers, and the air handler cabinet. For a typical single-system Ontario home, expect $350 – $650. Homes with two or three systems, common in the larger east-side subdivisions near Edison Avenue and the Ontario Ranch area, run $650 – $1,400 depending on total duct footage and accessibility.
Whole-System Source Removal
We don’t vacuum what we can reach and call it done. Our crews use Rotobrush rotary brush systems to agitate debris off duct walls, coupled with Nikro negative-air machines that maintain suction at the collection point so dust doesn’t escape into your living space. Every register gets removed and cleaned. The air handler blower and coil are inspected and documented.
Video Inspection and Documentation
Because you can’t see inside your ducts, we show you. Our video inspection records conditions before and after cleaning, with timestamps. In Ontario’s older homes, we specifically document the condition of original metal trunk lines and any accessible joints that need sealing. You get the footage, not just our word.
Commercial Air Duct Cleaning in Ontario
Commercial Air Duct Cleaning in Ontario covers retail spaces, offices, warehouses, and light industrial facilities along the I-10 corridor, the Ontario Airport district, and the business parks near the Convention Center. Typical commercial jobs run $800 – $2,500 depending on system count, square footage, and whether the building operates on a single rooftop unit or multiple split systems.
After-Hours and Weekend Scheduling
Commercial spaces in Ontario can’t shut down for ductwork during business hours. We schedule evenings and weekends to avoid disrupting your operation. Our crews arrive with their own lighting and containment, work the agreed scope, and leave no debris behind.
NADCA-Aligned Documentation for Property Managers
Property managers and facility supervisors get written scope, before-and-after photo documentation, and a completion certificate for their files. If your Ontario commercial lease or insurance policy requires periodic duct maintenance, our documentation satisfies standard compliance requests without extra charges.
Trusted Brands We Service in Ontario
We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Abatement Technologies for Ontario customers who want upgraded protection after their system is cleaned. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use, not hardware-store gear. If your Ontario home needs a filtration upgrade after cleaning, we can source and install the right unit without a second trip.
Common Air Duct Cleaning Problems We See in Ontario Homes
- Unsealed original metal ductwork in pre-1970 tracts. In homes south of Holt Blvd and near downtown Ontario, we find 1950s – 60s round metal supply trunks that were never wrapped or sealed. Attic dust and insulation fibers pull straight into your supply air every time the blower cycles. Cleaning without sealing the accessible joints leaves the problem active.
- Sagging flex duct in east-side two-story homes. The 1980s – 2000s subdivisions near Ontario Ranch and Edison Avenue use attic-run flex duct that kinks at elbows and traps dust. A single-system clean often misses the second-floor air handler and its separate return path entirely.
- Santa Ana wind re-contamination. Ontario sits in the Inland Empire dust corridor. Fall and winter wind events push fine desert particulate through attic vents and poorly sealed returns. Surface-only cleaning without sealing plenums and connections means ducts re-contaminate within weeks.
- No documentation on invisible work. Homeowners can’t verify duct interiors without photos or video. We document the air handler, blower motor, and duct runs before and after, so you have proof the job met NADCA source-removal standards.

Last fall, we cleaned a 1962 single-story home near Holt Blvd and Vine Ave where the original round metal supply trunks had never been wrapped or sealed, and a camera inspection showed attic insulation fibers caked along the first 8 feet of the supply run. We set up HEPA filtration and negative pressure, used agitation tools with Rotobrush equipment, and then sealed the accessible joints before balancing the registers. The homeowner noticed the dust film on furniture dropped within a week.

FAQs About Air Duct Cleaning in Ontario
Yes, each system is quoted and cleaned separately because each has its own air handler, duct network, and return path. A typical two-system Ontario home runs $650 – $950 total. Call (361) 326-5060 and we’ll scope each system during the free estimate.
We provide time-stamped video inspection before and after, plus photos of the air handler, blower, and accessible trunk lines. In Ontario’s older homes, we specifically document the condition of original 1950s – 60s metal ductwork. You see what we saw.
Ontario’s Inland Empire location means Santa Ana winds push fine desert dust through attic vents and poorly sealed returns, and summer temperatures over 100°F keep HVAC systems running nearly year-round. Dust, pollen, and microbial buildup accumulate faster here than in milder coastal climates. Most Ontario homes benefit from cleaning every 3 – 5 years, sooner if you have pets or recent renovation.
Yes. We schedule residential and commercial jobs separately to match the right crew and equipment, but we can coordinate both under one account for Ontario property owners. Commercial pricing starts at $800 for single rooftop units.
No, dryer vent cleaning is a separate service with its own pricing and scope. In Ontario’s dry climate and high-dust environment, lint buildup in dryer vents creates genuine fire risk and extends drying times. We offer dryer vent cleaning as an add-on, not bundled into duct cleaning, so you know exactly what you’re paying for.
