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.
Fast, Reliable HVAC Cleaning Across Dublin
HVAC cleaning in Dublin doesn’t have to be a guessing game. We scope every system individually, give you one written price before any work starts, and show you before-and-after photos of your own ducts when we finish. If you’re noticing weak airflow in the upstairs bedrooms of a two-story near Dublin Sports & Community Center, or dust accumulating fast in a 1970s ranch over near Hacienda Crossings, we can usually get a crew to your Dublin home quickly, without the bait-and-switch pricing this trade is known for. Call (737) 727-2314 and a real person answers, not a voicemail tree.
Why Cardinal Air Duct Cleaning Is Dublin’s Preferred HVAC Cleaning Company
We’re part of the Relay Home Co. family, founded 2005, and every Dublin job is held to The Relay Visibility Guarantee. That means you get a live trackable arrival time, a written price before anything is touched, before-and-after photo proof, and a digital invoice you can pay from your phone. The tech who shows up is background-checked, uniformed, and you’ll know their name before they ring the doorbell. Omar Haddad leads our team, and he built our process around one question: would a homeowner feel good about this if the price tripled at the door? If the answer is no, the process changes.
Our Dublin customers consistently tell us the same thing: the price didn’t move, the tech explained what he was doing, and the photos made it obvious the work happened. That’s the standard, and it applies to every job without exception. If the work isn’t right within 365 days, we come back and make it right. That’s the 365-Day Done Right Promise, and it covers every booking.
Because crews serve Dublin locally, we know the housing stock: older single-story ranch homes with long duct runs and tight attics off Dublin Boulevard, newer builds near Fallon Road with high ceilings and second-floor systems, and everything in between. That local familiarity means we show up knowing what to look for, not just with a vacuum and a coupon.
AC Coil Cleaning in Dublin
AC coil cleaning in Dublin runs $200 – $380 for the evaporator coil on a typical system. Dublin’s summer heat pushes AC units hard, and when the evaporator coil sits damp and loaded with dust and pet hair, it loses efficiency fast. You’ll see it as higher summer bills, longer run times, or a system that never quite reaches the thermostat setting on a 95-degree afternoon out near the San Ramon border.
What the job involves
We remove the access panel, inspect the coil with a camera, and use professional-grade cleaning agents that break down the film of dirt without corroding the aluminum fins. On a typical Dublin home, we’ll also treat the coil afterward to slow future buildup. A clean coil lets the refrigerant actually do its job, and you’ll notice it on the first hot day.
When to act
If your system is three or four years old and has never had the evaporator coil cleaned, it’s due. Dublin’s tree pollen in spring and summer dust make it worse. If your AC freezes up or blows warm air, the coil is often the culprit, and cleaning it is the first thing we check.
AC Cleaning in Dublin
AC cleaning in Dublin typically runs $350 – $650 for a full system, depending on the number of return drops, whether we’re also cleaning the air handler, and how accessible the duct runs are in your attic or crawlspace. That’s not a per-vent quote that quietly becomes something else once the tech is inside. It’s one price per system, written down, agreed before work starts.
System-level, not vent-count
Dublin’s housing mix is roughly split between older single-story ranch homes built in the 1960s – 70s and newer higher-ceiling two-story builds. The duct runs, number of register drops, and system size vary significantly from street to street. A real AC cleaning here has to be scoped per system, not by a flat per-vent count that assumes every home is laid out the same way.
Negative pressure and HEPA containment
We don’t just brush debris loose and hope it falls out. We set up negative-pressure extraction with our Rotobrush system and Nikro HEPA filtration, which means the loosened debris goes straight into the vacuum, not back into your living room. For homes near I-680 with heavy dust loads, this is the difference between a cleaning that lasts and one that just rearranges the dirt.
Trusted Brands We Service in Dublin
We service and clean systems from all major manufacturers, and we stock common parts locally for Dublin jobs, including filters from Honeywell and Aprilaire. If your system uses these filters, we’ll inspect them during your cleaning and let you know if they need replacing. We also run Nikro HEPA vacuums and Abatement Technologies containment units on the truck, so the equipment matches the job. No shop-vac shortcuts.
Common HVAC Cleaning Problems We See in Dublin Homes
- Collapsed flex runs in two-story homes. Dublin’s newer builds often route flex duct through tight chases, and when it sags or collapses, airflow to upstairs bedrooms drops sharply. A camera inspection finds it in minutes.
- Long, dusty duct runs in 1960s – 70s ranch homes. Older Dublin homes near Hacienda Crossings have extended trunk lines that collect decades of dust, pet dander, and debris. These systems usually need full cleaning plus air handler service, not just a register wipe-down.
- Coils caked with pollen and dust. Dublin’s spring pollen season is rough on evaporator coils, and a dirty coil makes the whole system work harder. We clean and treat the coil so it doesn’t just re-foul in six months.
- Systems where the blower motor is pulling debris through. If the filter was replaced rarely or the previous cleaning did not use HEPA containment, the blower wheel gets coated, which reduces airflow and shortens motor life. We open the air handler and clean the blower wheel while we’re there.

FAQs About HVAC Cleaning in Dublin
For most Dublin homes, every 4 to 7 years is honest. Homes with pets, heavy pollen exposure from the surrounding hills, or residents with allergies may need it every 3 to 4 years. If you’ve recently finished a remodel that kicked up drywall dust, or the previous owner had the system cleaned never, it’s worth doing sooner. Call (737) 727-2314 and we’ll help you figure out if you actually need it.
Per system. We will never quote you a per-vent price that quietly grows once the tech is inside your home. Every Dublin job gets one written price for the entire system, agreed before any work begins. If you’ve been quoted per vent elsewhere, that’s a red flag.
It includes a camera inspection, cleaning of the supply and return ducts, the air handler, the blower wheel, and the evaporator coil, plus coil treatment. We use Rotobrush rotary brushes, Nikro HEPA filtration, and negative-pressure extraction so debris leaves the system, not your living room. On Dublin homes with multiple systems, we scope each one separately in the written estimate.
Yes. Every Dublin customer receives before-and-after photos of their own ducts, registers, coil, and blower. You’ll see the difference with your own eyes, and the photos are delivered digitally. That’s part of The Relay Visibility Guarantee and the 365-Day Done Right Promise: if the work isn’t right, we return and correct it at no charge.
Sometimes, depending on our Dublin schedule, but we don’t promise same-day service as a marketing line. What you’ll get is a straight answer on the phone about when we can arrive, and a live trackable arrival window so you’re never waiting around. Call (737) 727-2314 and we’ll give you the earliest honest slot, not an empty promise.
