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 Antioch
Air duct cleaning in Antioch, CA typically costs between $425 and $690 for a standard single-system home, with larger two-story houses running $550 to $850. The work takes 3 to 5 hours and includes camera inspection of your supply and return ducts, rotary brush agitation under negative pressure, and before-and-after photos of your own ductwork. That’s the straight answer on price and process, because nobody in Antioch should hand over a deposit without knowing exactly what they’re paying for. Call us at (737) 727-2314 and a live person picks up, day or night.
We know Antioch neighborhoods like Mira Vista Hills, Dallas Ranch, and the grid of older streets off G Street and Lone Tree Way. We know the 1970s ranch houses with original duct trunks, the 1990s stucco homes with flex runs, and the newer infill builds east of Somersville Road. Why does that matter? Because the age and layout of your duct system changes how we clean it, not just how we quote it. Our Air Duct Cleaning team works across all of Antioch with a written price before any work starts, and we never change it once the van is parked in your driveway.

Air Duct Repair in Antioch
Air Duct Repair in Antioch usually means sealing a separated joint, patching a punctured flex run, or replacing a collapsed section of return trunk that’s pulling attic air and insulation fibers into your system. On a 1978 ranch house off G Street near downtown Antioch, our tech camera-inspected the supply and return ducts and found the return trunk lined with fiberglass batting that had collapsed at a joint, feeding insulation fibers straight into the air handler. We ran agitation tools and a Rotobrush whip through every branch under negative pressure with HEPA filtration at the truck, sealed the failed joint, and showed the homeowner before-and-after photos of the same duct sections on our tablet. Repair work like this runs $180 to $480 depending on access and how much duct needs replacing, and it’s quoted before we start.
Separated joints and collapsed flex runs
Older Antioch subdivisions from the 1970s and 1980s often have original rigid metal trunks with flex branches, and the foil-backed flex degrades over time in the dry Diablo Valley heat. When a flex run separates at the boot or the inner liner tears, conditioned air pours into the attic instead of your bedrooms. That’s money leaving through the gable vents every month. We camera-inspect first, then give you a written repair price.
Return-side damage and insulation pull-through
Homes built before code changes in the mid-1980s commonly have return trunks lined with fiberglass batting or duct board. Over four decades, the facing material breaks down and the insulation sags or collapses. When that happens, your air handler is breathing fiberglass and spreading it through the house. We remove the failed liner, install rigid metal where practical, and show you the difference on camera before we seal it up.
Ductwork Cleaning in Antioch
Ductwork Cleaning in Antioch is a source-removal job, not a spray-and-go treatment. The dry Diablo Valley climate means your ducts collect fine mineral dust, soot from fireplace season, and attic insulation fibers rather than the humid mold film you’d find closer to the Bay. That changes the entire approach: we use mechanical agitation to break debris off the duct walls, then pull it out under negative pressure through a Nikro HEPA vacuum at the truck, rather than pushing it around with a spinning brush and hoping for the best. A full system cleaning for a standard Antioch home runs $425 to $690, and we agree on that price in writing before the first register is pulled.
Full system cleaning, not spot work
Some companies charge per vent and count registers when they arrive, which is when the price starts climbing. We don’t do that. One flat price per system, agreed before we start, and it covers the supply side, the return side, all registers, the trunk lines, and the plenum. You’ll see before-and-after photos of your own ducts on our tablet when we finish, so you know what was in there and what’s gone.
Video inspection before and after
We run a camera through the ducts before cleaning to locate damage, blockages, or collapsing liner material. That inspection shapes the quote: if your system is clean and sealed, we’ll tell you honestly that you don’t need a cleaning right now. If it’s loaded with construction debris from a recent Antioch remodel or pet fur from a three-dog household in Dallas Ranch, you’ll see it. We don’t sell duct cleaning to people who don’t need it.
Trusted Brands We Service in Antioch
Our crews work on systems with Aprilaire filtration units, Abatement Technologies containment setups, Guardsman accessories, and Rotobrush cleaning tools already in the house. We stock common replacement parts for these brands on our trucks, so a standard repair on an Aprilaire media cabinet or a Guardsman damper doesn’t turn into a two-visit ordeal. For Antioch customers, that means faster turnaround and one service call instead of a parts-ordering delay. If your system uses an Aprilaire 2400-series media filter or a newer MERV 13 Aprilaire cabinet, we’re set up to clean it, replace media, and verify airflow the same visit.
Common Air Duct Cleaning Problems We See in Antioch Homes
- Fine mineral dust from the Diablo Valley climate. The dry east Contra Costa air carries fine particulate that settles inside duct runs year-round. Without negative-pressure extraction, a brush-only cleaning just suspends that dust and redeposits it through the house within a week.
- Collapsed return trunk liner in 1970s and 1980s builds. Original fiberglass-lined returns in ranch homes near G Street and Lone Tree Way degrade after 40-plus years, sending insulation fibers into the air handler and through the supply registers. It’s a repair issue first, a cleaning issue second.
- Flex runs separated at the boot from attic heat cycling. Antioch summers push attic temperatures well past 120 degrees, and that repeated expansion and contraction works flex connectors loose over time. Loose flex means conditioned air in the attic, not in your hallway.
- Construction dust from infill and remodel activity. Antioch’s newer neighborhoods and a steady rate of kitchen and bath remodels mean plenty of homes have drywall dust and sawdust inside ducts that were never cleaned after the project wrapped. That dust coats the blower wheel and shortens motor life.

FAQs About Air Duct Cleaning in Antioch
Most Antioch homes need duct cleaning every 4 to 6 years, not annually. With no pets, no recent remodel, and the dry Diablo Valley climate, your ducts simply don’t load up fast enough to justify a yearly cleaning. If you have multiple pets, a smoker in the house, or a full remodel that just wrapped, that timeline shortens to every 2 to 3 years. The honest answer is that a camera inspection tells you more than a calendar does. Call us at (737) 727-2314 and we’ll scope it before we quote anything.
Because per-vent pricing is how duct companies bait a low number and then inflate it once they count your registers. We quote one flat price per system, agreed in writing before work starts, and it doesn’t change no matter how many vents, trunks, or returns your house has. That’s the only way to know what you’re actually paying. The price you sign is the price you pay.
We camera-inspect the supply and return ducts first, then run mechanical agitation tools and a Rotobrush whip through every branch under negative pressure with HEPA filtration at the truck. The loosened debris goes straight into the vacuum, not back into your living room. After cleaning, we run the camera again so you see your own ducts before and after on our tablet. Then we seal any damaged sections we flagged and give you the written invoice.
Yes: the return trunk is the weak point. Original fiberglass duct board or foil-faced lining from that era breaks down after 40-plus years in the attic heat, and the facing collapses or the insulation sags into the air handler. If your upstairs supply vents have a chalky, gray residue around the vanes, that’s often insulation fibers. We camera-inspect the return first, because repairing that before cleaning saves you from re-cleaning the whole system six months later.
No, your dryer vent is a separate run from the wall behind your dryer to the exterior vent, and it’s a separate service. We do offer Dryer Vent Cleaning in Antioch as part of our HVAC and dryer vent service line, and an Antioch home with a rigid or semi-rigid dryer duct that hasn’t been cleared in three-plus years should get it done. Lint accumulation is a fire risk, not just an airflow problem. Ask when you call and we’ll scope both while we’re there, each with its own written price before work starts.
