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 HVAC Cleaning Across Antioch
HVAC cleaning in Antioch, CA typically runs $350 – $650 for a full system cleaning depending on your home’s duct configuration, and most jobs are completed in a single visit. If your vents are pushing dust onto furniture along Hillcrest Avenue or your allergies spike every time the furnace kicks on in a Prewett Ranch home, the system itself is usually the culprit. We clean the entire path air travels through: supply ducts, return ducts, the blower, coils, and the air handler. Call (737) 727-2314 for a written quote before any work begins, and we’ll walk you through exactly what your home needs.
Why Cardinal Air Duct Cleaning Is Antioch’s Preferred HVAC Cleaning Company
Antioch homeowners call us because we show up on time, name our price in writing before the first tool comes off the truck, and document the work with before-and-after photos of their own ducts. No other local outfit operates the way we do. Our technicians arrive in uniform, background-checked, and you know the tech’s name before they open the door. That matters when someone is moving through your house with professional equipment and you want to know who they are.
We run professional-grade gear, not a truck-mounted shop vac. Our Rotobrush rotary brush systems agitate caked debris off duct walls, then Nikro HEPA-rated vacuums pull it out under negative pressure so nothing re-enters your living space. For homes needing containment on tight crawlspaces or attic runs, Abatement Technologies units keep the mess sealed. This is the same standard we hold for every job, from a 900-square-foot bungalow off Lone Tree Way to a four-bedroom two-story near the Antioch Marina.
Omar Haddad leads our Antioch service area and every booking carries 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 isn’t a sales line. It’s the longest-standing satisfaction window in the trade, and it applies to every job without exception. Antioch residents have called us after a previous duct cleaner quoted $79 on the phone and left a $900 invoice on the counter. We don’t do that. Written price first. Always.
AC Vent Cleaning in Antioch
AC vent cleaning in Antioch is the job of clearing debris from the supply and return register openings, the boots behind them, and the accessible duct runs that connect to your air handler. During Antioch summers, when the Delta breeze dies and the AC runs for six or eight hours straight, dust, pet hair, and lint accumulate along the interior walls of these runs. You’ll see it first as a film on the louvers of your ceiling registers. In homes near the Antioch waterfront bluffs, the additional moisture in the air causes that debris to cling rather than blow through, which means it builds up faster than in drier inland parts of Contra Costa County.
Two-Phase Cleaning Procedure
We start with a camera inspection of your supply and return runs to see what’s actually in there. Then we set up negative-pressure extraction using a Nikro HEPA vacuum at the air handler while our Rotobrush agitation tool mechanically scrubs the duct walls free of debris. The loosened particles get pulled directly into the vacuum containment, never back into your living room. Every register you flagged at the start gets photographed before and after, so you can see the difference on your own phone.
When Antioch Homeowners Should Schedule
You need AC vent cleaning when visible dust returns within a day or two of wiping your registers, or when rooms at the end of long duct runs feel stuffy even with the AC on. On two-story homes near Gentrytown, we frequently see the upstairs runs packed with years of skin flakes, construction dust, and insulation fibers simply because the return path pulls air across the floor. A standard AC vent cleaning in Antioch runs $350 – $650 depending on the number of runs and whether the air handler needs cleaning too. We quote one flat price per system before anything starts.
Furnace Duct Cleaning in Antioch
Furnace duct cleaning in Antioch is the heating season’s version of the same job, but it focuses on the runs that carry warm air from your furnace to your vents through the winter. Antioch’s pre-1960s housing stock along the downtown grid and the waterfront bluffs often has original unlined sheet-metal ducts, which corrode at the seams and trap decades of dust, while the 1980s and 1990s subdivisions further south use flex runs that sag and kink in the attic. Both present different cleaning challenges, which is exactly why we inspect before we quote.
Supply Runs, Return Paths, and the Blower
A proper furnace duct cleaning always includes the blower motor and fan housing, because that’s where debris grinds against moving parts and shortens the unit’s life. In a 1970s two-story home near the Antioch Marina, our technician found the blower caked with drywall dust from a 2019 kitchen remodel, with return ducts pulling from a crawlspace lint pathway. We set up negative pressure with HEPA filtration, worked the supply and return ducts with Rotobrush tools, and the homeowner’s Aprilaire filter cabinet has held a MERV 13 filter since. That’s the difference between cleaning the ducts and cleaning the system.
Flat Per-System Pricing, Not Per-Vent Charges
You’ll hear some companies advertise a per-vent price in Antioch and then count forty vents and hand you a surprise total after the tech is already inside. We quote one flat price per system before any work starts, and it does not change at the door. A typical furnace duct cleaning in Antioch runs $350 – $650 for a complete system, including the blower, supply and return ducts, and a final camera inspection. If your home has severely damaged flex runs in the attic that need replacement rather than cleaning, we’ll show you photos and write up a separate repair price. No pressure, no bait.
Trusted Brands We Service in Antioch
Our HVAC Cleaning technicians work on systems from Carrier, Trane, Lennox, Rheem, Goodman, and York, and we keep common replacement filters, capacitor brackets, and flex-run sections stocked for fast turnaround on Antioch jobs. Whether you have an Aprilaire filter cabinet, a Honeywell media filter, or a standard Guardsman fiberglass rack, we clean the housing and seal the door so bypass air stops blowing unfiltered dust into your system. Most parts for these brands are available same-week, not special-ordered from a distributor two states away. For Antioch homeowners, that means fewer days without heat or AC while waiting on a component.
Common HVAC Cleaning Problems We See in Antioch Homes
- Mixed flex-and-sheet-metal routing. Older downtown homes use rigid metal for the main trunk and short flex connectors at the boots. Per-vent pricing schemes exploit this by counting both materials as separate charges. We quote one flat per-system price regardless of material mix.
- Kinked flex runs in Prewett Ranch and newer subdivisions. Flex duct installed with sharp bends collapses and chokes airflow, then collects dust at the choke point. We straighten and re-support these runs during cleaning, and we show you photos of what we found before and after.
- Caked blower motors from past remodels. Drywall dust, sawdust, and paint overspray circulate through the furnace blower during renovations and pack onto the fan blades. This shortens motor life and spreads fine dust through every room. Our cleaning includes blower removal and wash-down when the buildup is heavy.
- Missing documentation from previous cleanings. A surprising number of Antioch homeowners paid for duct cleaning years ago but received no photos, no written report, and no proof anything was actually done. Every Cardinal job ends with before-and-after camera inspection photos of your own ducts, timestamped and sent to your phone.
Pricing for HVAC Cleaning in Antioch, CA
For a standard Antioch home, a complete HVAC Cleaning in Antioch job runs $350 – $650. That’s one flat price per system, written down before we start. Smaller single-story homes on simple duct layouts trend toward the lower end. Two-story homes with long attic runs, crawlspace returns, or a heavily caked blower trend toward the upper end. What affects the price: the number of supply and return runs, whether the blower needs removal and cleaning, and whether flex runs need straightening or re-supporting. You get the written quote after our inspection, not after the work. Call (737) 727-2314 and we’ll schedule a time that works for your day.

FAQs About HVAC Cleaning in Antioch
Most Antioch homes need full HVAC cleaning every 3 to 5 years. Homes with pets that shed heavily, residents with severe allergies, or a recent remodel that filled the system with drywall dust may need it sooner, around every 2 to 3 years. If your ducts were cleaned properly and you’ve kept a MERV 11 or better filter changed regularly, you can often go five years without needing another cleaning. The honest answer is that some homes don’t need it as often as the discount per-vent companies claim. Call (737) 727-2314 and we’ll tell you straight whether yours actually needs it.
We charge one flat price per system, never per vent. Per-vent pricing is a tactic used to quote a low number on the phone and then inflate the bill once the technician counts every register in your house. That’s the exact bait-and-switch that Antioch homeowners have told us they’re tired of, and it’s why we write our price before any work begins. One price for the whole system, including supply and return ducts, the blower, and the camera inspection. It does not change at the door.
A typical job takes 3 to 5 hours and includes a camera inspection of your ducts, negative-pressure setup with HEPA filtration, mechanical agitation with Rotobrush tools, blower cleaning when needed, and before-and-after photos of your own registers and duct interior. We seal the workspace with containment where necessary, especially on older homes with crawlspace returns. The homeowner sees the photos before we pack up. If anything was missed, we fix it before we leave. Call (737) 727-2314 and we’ll walk you through what your specific home needs.
Yes, and we usually recommend it. Your furnace and AC share the same ductwork and air handler in most Antioch homes, so cleaning them together is one job, not two. It costs the same as a single system cleaning, not a double charge. The only exception is if your home has separate heating and cooling systems in different parts of the house, which is rare but occasionally seen in older Antioch homes with added square footage. We’ll confirm during the inspection.
No, and we’re honest about why. A proper HVAC cleaning in Antioch requires a camera inspection, negative-pressure setup with HEPA filtration, mechanical agitation, and before-and-after documentation. That takes time and shouldn’t be rushed. Any company promising same-day service is skipping steps, usually the camera inspection or the containment setup. We schedule within a few days in most cases. Call (737) 727-2314 and we’ll get you on the calendar, with a live trackable arrival window so you’re never waiting on a four-hour guess.
