Trusted Air Duct Repair for Antioch Homeowners
Losing airflow in one room is annoying. Losing it across a whole house usually means a duct has come apart, collapsed, or been crushed somewhere you can’t see. In Antioch, where a lot of the housing stock has had additions and HVAC changeouts layered on over the decades, disconnected runs and torn flex are far more common than most homeowners expect. That’s the gap we close: most duct cleaners stop at cleaning, and we repair what we find. Our technicians have up to 8 years of experience, and we bring professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies to every job rather than a shop vac and a hose. We set one flat price per system before work starts, so the number you agree to is the number you pay. Same-day repair is often possible. Call (877) 212-3243. We answer 24/7.
HVAC Duct Installation
HVAC Duct Installation is the full layout and fitting of a new duct system for a home, whether that’s a new build, an addition, or a house whose original ductwork was never sized correctly. You need it when the existing runs can’t be salvaged, when a room was added without proper ducting, or when a system was installed with undersized trunk lines that starve the far rooms. We design the layout around the air handler and the actual room loads, seal every joint, and verify static pressure before we call it done. Typical HVAC duct installation in Antioch runs $2,800-$7,500 for a whole house, depending on the number of runs, the length of the trunk, and whether the attic or crawlspace access is workable. You get a written estimate before anything is cut.
Sizing and Layout
Duct sizing isn’t guesswork. We measure room volume, the equipment’s rated airflow, and the run lengths, then match trunk and branch sizes to keep static pressure in range. A system that’s oversized on paper still underperforms if the returns are too small, so return sizing gets the same attention as supply.
Sealing and Insulation
Every joint gets mastic or foil tape and mechanical fastening, not just a wrap of tape that dries out in a season. Insulation value is matched to the space the duct runs through, since attic runs in Antioch’s summer heat lose cold air fast if they’re under-insulated.

Air Duct Replacement
Air Duct Replacement is pulling out a failed duct system and installing new ductwork in its place, and it’s the right call when the existing runs are beyond patching. That means duct board that’s gone soft and crumbling, flex that’s been torn by rodents or crushed by stored boxes, or a system so old that the leaks outnumber the solid sections. We scope the job by camera inspection first, so you see what we see before you commit. Air duct replacement in Antioch typically runs $2,200-$6,800 for a full system, with the range driven by run count, accessibility, and whether we’re replacing flex, rigid, or a mix. We close up what we open and photograph the finished work.
When Patching Stops Making Sense
If more than a few runs are compromised, patch repairs start costing more per year than a replacement would have. We’ll tell you honestly when you’ve crossed that line, and show you the footage behind the recommendation.
Material Choices
Rigid metal holds up best where ducts are exposed and get bumped. Sealed flex works well for long attic runs where a straight path exists. We match the material to the space rather than defaulting to one type for every house.
Ductwork Repair
Ductwork Repair is fixing the specific failures in a system that’s otherwise sound: disconnected joints, torn flex, crushed sections, failed mastic, and gaps at the plenum or register boots. It’s what you need when one room runs weak, when you hear whistling at a vent, or when dust keeps settling on the same furniture no matter how often you clean. We locate the failure with a camera and a pressure test, repair it properly, and re-test to confirm the fix held. Ductwork repair in Antioch generally runs $250-$1,200 depending on how many failures we find and how hard they are to reach. Small jobs get the same written estimate as large ones.
Locating the Failure
Air takes the path of least resistance, so the leak that causes your weak room is rarely in that room. Camera inspection inside the trunk finds the actual break instead of guessing at the nearest vent.
Sealing Methods
Mastic and embedded fabric mesh hold where tape fails. For larger gaps we bridge with metal before sealing, because a seal over a moving gap will crack again within a season.
Duct Replacement
Duct Replacement means swapping out a section or a whole branch of ductwork rather than repairing it in place, and it’s the practical option when a run has been crushed flat or soaked through. Water damage from a roof leak, rodent nests, and collapsed flex all fall into this category. We remove the failed section, match the new duct to the existing system’s sizing, and seal it into the trunk so the repair doesn’t create a pressure imbalance downstream. Duct replacement in Antioch usually falls in the $400-$2,400 range, depending on the length of the run and how much access the attic or subarea allows. We photograph the old section and the new before closing up.
Matching Existing Sizing
A replacement run has to move the same volume as the original, or the rooms downstream shift out of balance. We measure before cutting so the new section doesn’t create a new problem.
Access and Cleanup
Tight attic access slows the work but doesn’t change the outcome. We lay protection, contain debris, and haul the old duct out rather than leaving it in the attic.
Ductwork Installation
Ductwork Installation covers new duct runs added to an existing system, like a converted garage, a finished bonus room, or a kitchen remodel that needs its own supply and return. It differs from a full system install in that the new runs have to be balanced against what’s already there. We tie the new runs into the existing trunk with proper takeoffs, size them to the added load, and check that the air handler can actually carry the extra demand. Ductwork installation in Antioch typically runs $650-$2,900 for the added runs, depending on how many and how far the air has to travel. If the existing system can’t handle the addition, we’ll say so before you spend anything.
Adding Runs to a Live System
Every added supply pulls air the rest of the house was using, so the takeoff has to be sized carefully. Adding a return is often the difference between a cool room and a balanced one.
Balancing After Install
New runs change the pressure map of the whole system. We check airflow at the far registers after installation and adjust dampers so the original rooms don’t lose what the new one gained.
Brands We Service
We work with Honeywell and Aprilaire filtration and air-quality components, which means when a repair uncovers a filter housing that’s undersized or a bypass that’s leaking, we can recommend the right replacement from a product line we know well rather than improvising. Aprilaire media cabinets in particular need a clean, sealed fit at the plenum, and a lot of the airflow complaints we trace back to duct repair start with a filter door that never sealed properly.
Our cleaning and containment work runs on Abatement Technologies negative-air filtration and Nikro HEPA extraction, so the dust a repair stirs up gets captured instead of redistributed through the house. Whether you have Honeywell or Aprilaire components, Guardsman hardware at the registers, or any other make, we can help.

- One room never gets comfortable. A single room that stays warm in summer while the rest of the house is fine usually points to a disconnected or crushed run serving that room. Left alone, the equipment works harder and the problem spreads to the rooms downstream.
- Whistling or roaring at a vent. High-pitched noise at a register means the air is being forced through a restriction, often a collapsed section or a damper stuck closed. It’s a pressure problem, and pressure problems wear out blower motors.
- Dust settling faster than it used to. Visible dust on surfaces within a day or two of cleaning suggests the system is pulling from an open return or a broken joint in the attic. That dust is coming from somewhere it shouldn’t.
- Higher energy bills with no change in use. Leaking or disconnected ducts push conditioned air into the attic instead of the rooms. The bill climbs while comfort drops, and the equipment runs longer each cycle.
- Visible damage at a register boot. Torn flex or a gap where the boot meets the drywall lets attic air straight into the room. It’s usually a quick repair if it’s caught before the tear spreads down the run.
Our Process, Step by Step
- 1
Phone consultation and scheduling. We ask what you’re seeing and hearing so we arrive with the right equipment. We answer 24/7, and fast dispatch runs from 7am to 7pm.
- 2
Camera inspection of the system. A push camera goes into the trunk and branches so we can see the actual condition of the ductwork. You see the footage with us, not a summary afterward.
- 3
Pressure testing and airflow measurement. Static pressure readings at the air handler and airflow at the registers show where the system is losing performance. This is what separates a diagnosis from a guess.
- 4
Written estimate before any work. You get the scope, the flat price per system, and the reasoning behind it in writing. Nothing starts until you approve it.
- 5
Repair, verification, and before-and-after photos. We complete the repair, re-test to confirm it held, and give you photos of the before and after so you know exactly what was done.
How Much Does Air Duct Repair Cost in Antioch?
Air duct repair in Antioch typically costs $250-$1,200 for the repair itself, with a full duct replacement running $2,200-$6,800 when the system is past patching. A typical disconnected joint or torn flex repair in Antioch runs $250-$600 depending on how far into the attic the failure sits. A crushed trunk section or a failed plenum connection usually lands in the $600-$1,200 range because it involves bridging and resealing rather than a simple reconnect. Full duct cleaning Antioch combined with a repair adds to the total but is often the right call when the repair stirs up years of accumulated debris.
What affects the price: the number of failures found, how accessible the ductwork is, whether the duct is rigid metal or flex, and whether the repair requires removing and reinstalling insulation or drywall access panels. Accessibility is the biggest variable. A failure in a wide-open attic is a different job than one buried under a low roofline.
How to avoid overpaying: insist on a written estimate before work starts, ask for camera footage of the failure, and be wary of any quote given over the phone without an inspection. We set one flat price per system agreed before work starts, with no per-vent pricing and no surprise line items. Our free estimate includes the camera inspection, the pressure readings, and a written scope, so you can compare quotes on the same terms.

Frequently Asked Questions About Air Duct Repair in Antioch
Air duct repair is the physical fixing of ductwork that’s come apart, been crushed, torn, or sealed incorrectly, restoring airflow and stopping leaks into unconditioned space. It’s different from duct cleaning, which removes debris from a system that’s otherwise intact. We do both, which means a repair doesn’t have to wait on a separate cleaning appointment.
Most single-failure repairs take two to four hours on site, including inspection and re-testing. Larger jobs, like a full duct replacement or multiple repairs across the system, typically run a full day. We give you a realistic time estimate when we write the scope, not a rounded number.
Most air duct repairs in Antioch run $250-$1,200, with full replacement at $2,200-$6,800. The written estimate sets the final price, and it’s free. Call (877) 212-3243 for an exact quote.
Yes, we work with both Honeywell and Aprilaire filtration and air-quality components and can recommend the right upgrade when a repair uncovers a filter housing or plenum issue. Our familiarity with these product lines means the fix integrates properly with the rest of the system rather than sitting on top of it as an afterthought.
Same-day repair is often possible when you call early in the day. We answer 24/7, and fast dispatch runs from 7am to 7pm, Sunday through Friday. A call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm.
We stand behind the work with a satisfaction guarantee, and the specific warranty terms are written into your estimate so there’s no ambiguity later. If something we repaired fails, we come back and make it right. You’ll have the terms in writing before the job starts.
Clear access to the attic hatch or crawlspace opening and move anything fragile away from the work area. Secure pets in a room we won’t need to enter. Beyond that, you don’t need to do anything, and you’re welcome to watch the camera inspection with us.
