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.
Air Duct Cleaning Company in Ontario, CA
Air duct cleaning in Ontario, CA typically costs $350 – $650 for a whole-home system, with most jobs completed in a single visit. Homeowners in Ontario face a unique challenge: thousands of post-WWII tract homes with original ductwork that has accumulated debris for half a century, combined with Inland Empire dust and Santa Ana wind events that force HVAC systems to run almost year-round. At Hollis Air Duct Cleaning, we dispatch crews from our Inland Empire office to handle these exact conditions. Call (361) 326-5060 for a free estimate.
Why Ontario Homes Are Different
Ontario’s housing stock tells a clear story. The older core, south of Holt Blvd and around downtown, is packed with 1950s – 1970s slab-foundation tract homes built during the post-war boom. In these houses, we regularly find original round metal ductwork that was never wrapped or sealed. When the blower kicks on, attic dust and insulation fibers get pulled straight into the supply stream. This is not a maintenance issue; it’s a decades-old design gap that duct cleaning addresses directly.
The newer two-story subdivisions on Ontario’s east side, built from the 1980s through the 2000s, present the opposite problem: attic-run flex duct that sags, kinks at elbows, and traps dust at every turn. Add Ontario’s climate, routine triple-digit summers and Santa Ana wind events that push fine desert particulate through attic vents and poorly sealed returns, and the debris load inside local ducts is measurably heavier than in coastal markets. HVAC systems here run nearly year-round, so buildup happens faster and gets recirculated more often.
Our Main Ontario Services
We handle three core services for Ontario homeowners, each routed to its own dedicated page with local pricing and details.
Air Duct Cleaning in Ontario
Our Air Duct Cleaning in Ontario service targets the accumulated debris in aging forced-air systems. In the older tracts, we use Rotobrush rotary brush systems to dislodge buildup from original metal ductwork, then extract it with Nikro negative-air machines. For newer homes with flex duct, we adjust pressure and brush selection to avoid damaging the material. Every job starts with a written price and ends with before-and-after photos of your own ducts.

Dryer Vent Cleaning in Ontario
Our Dryer Vent Cleaning in Ontario service addresses a fire-safety issue that intensifies with local conditions. Ontario’s hard water and heavy dryer use leave lint buildup that restricts airflow and overheats the unit. We clean the full run from dryer to exterior cap, test airflow before and after, and flag any damaged venting that needs replacement. The 365-Day Done Right Promise covers this work too.

Duct Sealing in Ontario
Our Duct Sealing in Ontario service closes the gaps that pull attic dust and hot air into your system. In unsealed 1950s – 60s metal ductwork, we apply mastic sealant at joints and registers. For flex duct with disconnected runs, we reconnect and support properly. Sealing often drops energy bills 15 – 30% in these older Ontario homes, and we price it in writing before any work starts.

FAQs About Air Duct Cleaning Company in Ontario
No permit is required for standard duct cleaning or dryer vent cleaning in Ontario. Duct sealing that involves modifying or replacing ductwork may need a permit if it alters the HVAC system’s capacity or routing; we handle the inspection coordination on any job where that applies. Call (361) 326-5060 and we’ll tell you upfront if your specific job triggers a permit requirement.
Most Ontario homeowners get an appointment within 3 – 5 business days, with dispatch coordinated from our Inland Empire office.

Our phones are answered by a live person 24/7, so you can schedule anytime without waiting for a callback.
Yes. We clean and seal systems in both the older core and the newer subdivisions, but the work differs. Ontario Ranch homes typically have flex duct that requires gentler rotary brush settings and careful sealing at attic connections. Older tracts need aggressive debris removal from unsealed metal ductwork. We assess your system type during the free estimate and quote accordingly.
