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
In Ontario, CA, most homes shouldn’t wait longer than a week for duct cleaning, and a straight answer on price should come before any work starts. That’s how Cardinal Air Duct Cleaning operates. We send background-checked, uniformed technicians into Ontario neighborhoods with professional equipment, a written price handed to you before a single register is touched, and before-and-after photos of your own ducts when the job’s done. You’ll know the technician’s name before they pull up. If your vents are blowing dust that settles on furniture a day after you wipe it down, call us at (737) 727-2314 and we’ll walk you through what’s actually needed, not what pads an invoice.
Why Cardinal Air Duct Cleaning Is Ontario’s Preferred Air Duct Cleaning Company
We’re part of the Relay Home Co. family, founded 2005, and every job we run in Ontario operates under the same standard: total visibility from booking to invoice. That’s not a marketing line. You get a live trackable arrival window, a written price before work starts, and photo proof of what came out of your ductwork. Omar Haddad leads our team, and he built our Ontario scheduling and operations around one principle: homeowners in the Inland Empire are tired of vague estimates and surprise line items.
Our reputation in Ontario hangs on the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That covers every booking, no fine print, no carve-outs. It’s the longest-standing satisfaction window in the trade, and it means our technicians don’t cut corners on a Air Duct Cleaning job in a 1970s single-story off Grove Avenue or a newer two-story near the Ontario Mills corridor. We’d rather do it correctly the first time than come back.
Ontario homeowners also value something simpler: a live person answers our phones 24/7. No voicemail loops. When you call about duct cleaning in Ontario, you reach someone who can answer questions, not a phone tree.
HVAC Duct Cleaning in Ontario
HVAC Duct Cleaning in Ontario means sending professional-grade agitation and negative-pressure extraction equipment through every supply and return duct in your system, not running a shop vac over a couple of visible registers. Ontario sits at a weird confluence: the LA Basin’s afternoon sea breeze pushes moist marine air east through the San Gabriel Valley, where it meets fine inland dust. The result is a particulate blend that clings to duct walls differently than the dry desert grit you’d find further out toward Palm Springs. That mix settles into the supply lines first, then gets baked onto the return side by your furnace during winter cycles.
For a typical Ontario single-family home, full HVAC duct cleaning runs $395 – $695. That’s one flat price per system, agreed before we start. No per-vent pricing, no surprise add-ons when the crew finds an extra register behind a door.
Supply Duct Cleaning
Your supply ducts push conditioned air into every room, and in Ontario they collect the finest particulates because they’re under positive pressure. We run a Rotobrush rotary brush system through each supply run to loosen what’s adhered to the duct walls. Then negative-pressure extraction pulls that loosened debris into a Nikro HEPA vacuum, not back into your living room.
Return Duct Cleaning
Return ducts pull air back to your air handler, and they’re where we see the heaviest buildup in Ontario homes, especially in older single-story houses near South Euclid Avenue where ducts run through attics that hit 130°F in August. We clean every return drop, replace the filter, and show you what came out on camera before and after.
Vent Cleaning in Ontario
Vent Cleaning in Ontario covers the visible end of the system: the registers and grilles in your floors, walls, and ceilings, plus the immediate duct runs behind them. It’s what you see every day, and it’s what most people think of when they ask about duct cleaning. But here’s what matters: cleaning the vent face without addressing the duct behind it is cosmetic. Dust will blow back through within weeks.
For vent cleaning as part of a full system job in Ontario, you’re looking at $395 – $695 for a complete single system, depending on the number of returns and accessibility in your attic or crawl space. We quote one number for the whole job. If someone quotes you per vent, walk away or at least ask what the total will be once they count everything.
Register and Grille Restoration
Ontario homes built before 1990 often have metal registers with years of baked-on dust, paint overspray, and rust from humidity cycles. We remove, clean, and hand-wipe each one, and on badly corroded registers we’ll flag replacement options with real prices before doing anything.
Dryer Vent Safety in Ontario
While we’re in an Ontario home, we always check the dryer vent run. Lint is the leading fire-risk factor in a laundry room, and we’ve seen runs over 20 feet with three elbows packed with compacted lint. That’s a hazard, and ignoring it while cleaning HVAC ducts is a disservice.
Trusted Brands We Service in Ontario
Our Ontario customers run equipment from every major manufacturer, and we stock common filter sizes and components for Honeywell, Aprilaire, and Guardsman systems. Whether your air handler uses a standard 1-inch filter or a 4-inch media cabinet, we carry what’s needed and won’t leave you waiting on a parts order. Our extraction equipment includes Nikro HEPA vacuums and Abatement Technologies containment units, so the dust we loosen stays contained and leaves the house with us.
Common Air Duct Cleaning Problems We See in Ontario Homes
- Per-vent pricing surprises. A quote of “$25 per vent” sounds cheap until a 14-register house gets tallied at $350 for the vents alone, then hit with separate line items for returns, trunk lines, and the air handler. We quote one flat price per system, so the number you see on paper is the number you pay.
- Register-only cleaning that stirs dust. Vacuuming register faces without negative-pressure containment pulls dust out of one spot and pushes it into the room air. Proper cleaning in Ontario requires containment so debris goes straight into a HEPA-filtered vacuum.
- Lint pathway neglect. The dryer vent run is often ignored during HVAC cleaning, even though it’s the same trip and the same house. We check it every time because a clogged dryer vent is a real fire risk, not a maintenance footnote.
- Filter upgrades skipped. After a full duct cleaning, a clean system deserves a filter that can hold up. We stock higher-MERV options from Aprilaire and Honeywell and will show you the difference without upselling.

FAQs About Air Duct Cleaning in Ontario
In Ontario, a home typically needs duct cleaning every 3 – 5 years, but honestly, it depends on what’s happening inside your house. A single-family home off Vineyard Avenue with two dogs, old carpet, and windows open through spring will need it closer to every 3 years. A newer townhome near Ontario Mills with a high-MERV filter and no pets can stretch to 6 years. You’ll know it’s time when you see dust settling on furniture within days of wiping, when airflow feels weak at certain registers, or when you peel back a floor register and see a gray film on the duct walls. Call (737) 727-2314 and we’ll help you decide if it’s actually time or if you can wait another year.
One flat price for the whole system, always. We quote per system, not per vent. A typical Ontario home with 10 – 14 registers and one air handler runs $395 – $695 total, written down before we start. Per-vent pricing is how quotes quietly explode: $20 per vent sounds fine until you realize the quote didn’t include return drops, trunk lines, or the air handler itself. We don’t play that game. The price on the paper is the price you pay, and it doesn’t change when the technician arrives.
Duct cleaning removes dust, pet dander, pollen, construction debris, and the fine gray film that accumulates over years of heating and cooling cycles. In Ontario specifically, the blend includes marine particulates carried east by the afternoon sea breeze through the San Gabriel Valley, which mix with drier inland dust and cling to supply and return duct walls. It’s not glamorous, but it’s what your family breathes. We also remove whatever’s lodged in there: drywall dust from renovations, dead insects, and occasionally a child’s lost toy from a floor register.
Yes, and you should demand it from any company you hire. Every Cardinal job in Ontario includes before-and-after photos of your own ducts, taken with a camera we run through the system. Omar Haddad built this into our Relay Standard because you shouldn’t have to trust a verbal summary. You’ll see the duct walls before, the debris captured by the HEPA vacuum, and the clean ducts after. Digital invoices and photo proof go straight to your phone so you can review everything from the couch.
No, and here’s why: proper duct cleaning in Ontario is a scheduled job that takes 3 – 6 hours for a typical single-family home. A company promising same-day service is cutting corners somewhere, usually by skipping negative-pressure setup or rushing the rotary brush through the system. We’d rather schedule you within the week and do it right. Call (737) 727-2314 and we’ll get you on the schedule with a live trackable arrival window and a written price confirmed before we arrive.
