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 Dublin
Air duct cleaning in Dublin, CA typically runs between $450 and $850 for a full system on a standard two-story home, and most jobs are completed in four to six hours. That is one flat price per system, agreed in writing before any work begins, and it does not move once our tech arrives. If you live in Dublin and you’re tired of vague estimates or a price that shifts mid-job, call Cardinal Air Duct Cleaning at (737) 727-2314. We serve every Dublin neighborhood, from the 1980s tract homes near Hacienda Drive to the newer airtight builds off Fallon Road, and we know exactly how your ductwork behaves before we open a single register.
Why Cardinal Air Duct Cleaning Is Dublin’s Preferred Air Duct Cleaning Company
Dublin homeowners keep calling us back for one reason: we treat duct cleaning like a defined job with a defined price, not an open-ended service call. Omar Haddad built Cardinal’s Dublin crews around a simple rule – if you can’t see it, it wasn’t done. Every job wraps with before-and-after photos of your own ducts, taken with a Rotobrush camera wand, so you can see the supply and return runs we cleaned and seal that expectation right then.
Our techs know Dublin’s housing stock the way a local building inspector does. The 1990s two-story homes off Tassajara Road have flex duct runs that sag and crush in the attic heat. The newer builds near the transit center are tighter, so duct imbalances show up as pressure problems long before anyone sees dust. That local knowledge means we diagnose the right thing on the first visit, and our 365-Day Done Right Promise means if it isn’t right, we come back and make it right at no charge. We’re part of the Relay Home Co. family, held to The Relay Visibility Guarantee: a live trackable arrival time, a written price before work starts, and a digital invoice you can pay from your phone.
Air Duct Repair in Dublin
Air Duct Repair in Dublin means fixing the physical ductwork itself – seams that have separated, flex runs that have collapsed, collars that have popped loose at the air handler. These are common in Dublin’s 1980s and 1990s tract homes, where original flex duct in the attic breaks down over thirty years of Tri-Valley heat cycling. A disconnected or crushed duct does not hold air, and no amount of cleaning fixes that. Repairs typically run $180 – $450 per section depending on access and the length of the run being replaced or reconnected.
How Repair Differs From Cleaning
Cleaning removes debris from ducts that are still intact. Repair restores airflow to ducts that have failed. Our techs find the failure with a camera inspection first, then show you the footage before any work is quoted. That order matters – you should never pay to clean a system that needs a repair first.
What Gets Replaced Or Sealed
Common jobs include reconnecting a flex duct collar at the plenum, sealing a seam with mastic and foil tape, or replacing a crushed run between the main trunk and a register. Dublin’s dry summer heat accelerates flex duct breakdown, so a lot of what we fix are runs that have become brittle and torn. Every repair comes with the written guarantee from the 365-Day Done Right Promise, including a free second visit if the repair fails.
Ductwork Cleaning in Dublin
Ductwork Cleaning in Dublin is the full source-removal process: camera inspection, negative-pressure setup with HEPA filtration, mechanical agitation through every supply and return run, and post-cleaning photos. It is not a quick blow-through at the registers and it is not a shop vac in the floor grille. A full system cleaning for a typical Dublin two-story runs $450 – $850, and that is one price for the entire duct system, not a per-vent multiplier that balloons at the door.
How Source Removal Works
We set up a Nikro HEPA vacuum at the air handler to pull negative pressure on the system, then run Rotobrush agitation tools through each duct run. The loosened debris goes straight into the vacuum, not back into your living room. The process takes four to six hours on a standard home, and we photograph the same runs before and after so you can see exactly what was removed.
What We Actually Pull Out
In Dublin homes, the common load is drywall dust from old remodels, pet hair and dander, and the fine Tri-Valley dust that settles into return ducts over years of open windows in the summer. A recent job off Tassajara Road turned up roughly two cups of drywall dust in a bonus-room flex run alone, plus a crushed section and disconnected collar at the air handler. Cleaning without fixing that disconnect would have been wasted money.
Trusted Brands We Service in Dublin
Most Dublin homes run Carrier, Lennox, Goodman, or Trane systems, and our techs work on all of them. We also service and install filtration products from Aprilaire and Guardsman when a Dublin homeowner wants better air quality after cleaning, and our containment setup uses Abatement Technologies units when we are dealing with heavy debris or a remodel job that left fine particulate throughout the system. If you need filters for a Honeywell media cabinet, we stock common sizes on the truck for Dublin calls, so there is no second trip and no surprise upsell. We carry the parts for the jobs we actually see here, not a generic inventory.
Common Air Duct Cleaning Problems We See in Dublin Homes
- Crushed flex runs in older two-story homes. The 1980s and 1990s tract builds near I-580 and I-680 often have flex duct that has sagged, kinked, or collapsed in the attic over thirty years of heat cycling. If a room has weak airflow while the return pulls hard, the duct itself is likely the problem, not the dirt inside it.
- Drywall dust from past remodels. Dublin saw a lot of renovation work through the 2000s and 2010s, and much of that dust settled into the supply and return ducts and stayed there. A camera inspection before cleaning shows how much of your system’s debris load comes from construction, not daily living.
- Unbalanced supply and return in newer airtight homes. Newer Dublin builds are sealed tight, so when the supply and return are out of balance, you feel it as door slam pressure or rooms that never reach temperature. Cleaning the ducts does not fix an imbalance, but diagnosing it on the same visit means you are not paying for a service that misses the real problem.
- Return-side dust that never gets touched by basic cleanings. A quick blow-through at the registers leaves return ducts full of debris, because negative pressure is what actually pulls that dust out of the return path. We pull and clean the blower motor and air handler as part of every system cleaning, not as an add-on.
Pricing for Air Duct Cleaning in Dublin, CA
A full air duct cleaning for a standard Dublin home runs $450 – $850 per system, one flat price agreed before we touch a single duct.

Smaller single-story homes or condos off Dougherty Road may run $300 – $450. If you have a larger two-story or a system with long attic runs, expect the upper end of the range.

FAQs About Air Duct Cleaning in Dublin
Most Dublin homes need a professional duct cleaning every three to five years, more often if you renovated recently, run pets indoors, or live near active construction. A camera inspection is the only way to know whether your ducts are actually loaded with debris or just look dusty at the register. Call (737) 727-2314 and we will inspect and tell you honestly whether cleaning is worth doing right now.
Because per-vent pricing is how disreputable companies make a low quote look cheap and then inflate the final bill once the tech counts registers that were never mentioned on the phone. We quote one flat price for your entire duct system and we hand it to you in writing before work begins. That number does not change at the door, and it covers every supply and return run.
The photo set shows the interior of your actual supply and return ducts, captured with a Rotobrush camera wand before and after cleaning. You will see the same runs in both photos, so you can confirm debris was removed and not just blown around. Every Dublin job includes this documentation as part of The Relay Visibility Guarantee, and you keep the photos with your invoice.
It does contribute some fine road dust and particulate, especially in homes with older window seals or in neighborhoods near the interchange ramps. But the larger drivers in Dublin are usually drywall dust from past remodels and pet dander, which accumulate regardless of traffic. A camera inspection will show what is actually in your system, not what we guess is there.
It is not worth doing if your ducts are clean and your real issue is a crushed flex run, an unbalanced supply/return design, or a failing blower motor. Cleaning will not fix those problems and you would be paying for a service that misses the actual fault. We inspect first and will tell you if repair is what you need instead. Call (737) 727-2314 for a free inspection and an honest recommendation.
