Air Duct Repair in Edinburg - We Measure the Leak Before We Quote

Trusted Air Duct Repair for Edinburg Homeowners

When a supply run comes loose in the attic or a return chase starts whistling, the problem isn’t your AC unit. It’s the ductwork moving the air. Duct Cleaning Edinburg repairs that ductwork as a standalone job, so you’re not stuck with a contractor who flags a torn flex run and then walks away because repair isn’t his line. Our technicians have up to 10 years of experience, and we bring Rotobrush and Nikro equipment to the diagnosis instead of guessing from the thermostat. Edinburg homes with a damaged run lose cooling into the attic and pull hot air back through the return. That’s a comfort problem you can usually stop in a single visit. Call (877) 566-6144. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

HVAC Duct Installation

HVAC Duct Installation is the job of running a complete new duct system when none exists or the old layout can’t be saved, such as a converted garage, an addition, or a gut renovation where the original layout was built for a different floor plan. We size the supply and return runs to match the blower the system actually has, then seal every joint we can reach. Because we handle this as duct specialists, not installers who do ductwork on the side, the trunk-and-branch layout gets the attention it needs. In Edinburg, this typically runs $1,800-$4,500 depending on how many rooms need drops and how accessible the attic path is. The written estimate sets the final price, and the estimate is free.

Layout and Sizing

A duct system that’s undersized for the tonnage of the unit will feel weak at the far rooms no matter what setting the thermostat is on. We map the run lengths and count the supply registers before a single piece of flex goes in so the air has somewhere to go.

Attic Access and Sealing

Most Edinburg homes route ducts through a low-pitch attic, and working there takes patience in the summer heat. We seal every seam and boot we can reach with mastic, then check that the finished runs sit clear of the deck.

Air Duct Replacement

Air Duct Replacement means pulling out a run or a whole branch that’s beyond repair and putting new duct in its place. The usual reasons are crushed flex under a re-roof, disintegrated liner inside older duct board, or sections that have been patched so many times there’s nothing original left to seal. This is a different job from cleaning. You can’t clean a duct that has collapsed or lost its inner vapor barrier, and trying to just blows insulation fibers into your rooms. We quote the replacement per run and stage the work so the rest of the house keeps some airflow. In Edinburg, Air Duct Replacement typically runs $600-$2,800 depending on the number of runs and the attic layout. The written estimate sets the final price.

When a Run Can’t Be Saved

If the inner liner is torn, the outer jacket has separated, or a run has been stomped flat under a roofer’s plywood, replacement is cheaper than repeated patching. We show you the before photos so the call is yours to make.

Matching New Duct to the Old System

New duct needs to be sized to the existing blower and the room it serves, not to whatever box is closest to hand. We measure the opening and the run length before ordering anything.

Ductwork Repair

Ductwork Repair is the fix for the smaller breakdowns: a joint that’s come apart, a boot that no longer meets the register, a tear from a careless plumber or electrician, or a return chase where the panned joist has failed. Symptoms usually show up as rooms that stay warm in summer, a whistle at one register, or dust in the house that nothing seems to stop. We locate the leak with pressure testing and visual inspection in the attic, then seal or reattach the failed section. In Edinburg, Ductwork Repair typically runs $200-$750 depending on how many joints fail and how much of the attic is reachable. The written estimate sets the final price, and there’s no flat quote over the phone.

Leak Detection in Attics

A supply leak in the attic pulls hot outside air into the house through the return. We track the loss to a specific joint or split so we’re fixing the leak that matters, not spraying sealant at everything.

Sealing Joints and Boots

Mastic and mesh tape on a properly cleaned surface hold up far better than duct tape, which dries out and fails. We clean the surface, then seal every joint we can safely reach.

Duct Replacement

Duct Replacement is the large-scale version of the job: a full replacement of the trunk line and the visible distribution runs, which we reach for when the existing duct has failed system-wide, not in one place. That’s common in Edinburg homes where the original flex runs have baked in the attic over many summers, or where an older duct board trunk has lost its inner liner and shed fibers into the airstream. We pull the failed duct out, set new insulated runs, and seal and strap them so the run doesn’t sag into the deck. In Edinburg, Duct Replacement typically runs $2,400-$6,000 depending on the size of the system and how much of the attic is accessible. The written estimate sets the final price.

Full System vs. Spot Replacement

If three runs are failing the same way, that’s a system pattern, and spot repairs will only chase the next failure. We check the whole attic so the fix isn’t half a fix.

Insulation and Vapor Sealing

Replacement duct has to be insulated for the attic heat and sealed with a proper vapor jacket. Otherwise the new duct is only slightly better than the old duct it replaced.

Ductwork Installation

Ductwork Installation covers new duct added to an existing system, such as a new run to a remodeled room, a proper return added for a pressure balance problem, or a laundry and bathroom run that was never done right. Adding a run without rebalancing the system can starve the rooms that already worked, so we check the existing pressure and airflow before adding anything. If you’re finishing a room in Edinburg and need the duct run done correctly the first time, this is the scope we take on. Typical ductwork installation runs $350-$1,200 per run depending on length and access, with the written estimate setting the final price.

Adding a Run to an Existing System

A new supply run needs to be sized from the room load, not from whatever flex happens to fit the register. We do the sizing, then confirm the blower has the capacity to serve it.

Balancing the New Against the Old

Adding air to one room takes air from the others. We check static pressure at the air handler after the install so the rest of the house still gets its share.

Brands We Service

We work with Rotobrush rotary brush systems and Nikro HEPA vacuum equipment on every repair call, and we know Honeywell and Aprilaire air-quality components well enough to diagnose when a failed damper or UV housing is affecting the duct run. Those two brands show up in a lot of Edinburg attics, and knowing where their dampers and filter housings wear out saves us from pulling duct apart when the problem is actually in the housing.

We’re a duct shop, not a dealer, so we don’t claim to stock OEM or genuine parts. Whether you have Honeywell, Aprilaire, or any other make, we can help. If your system uses a brand that isn’t in that list, tell us on the call and we’ll be honest about whether it’s a job we take on.

Signs You Need a Pro Right Now

• Rooms that never cool properly. If one or two rooms stay warm while the rest are fine, a supply run is likely leaking or detached in the attic. That’s a repair, not a thermostat setting.
• Whistling or humming at a register. A high-pitched whistle usually means a joint has blown apart or a boot has separated from the register. Left alone, that leak dumps cooled air straight into the attic.
• Dust that keeps coming back. If you clean a room and two days later it’s dusty again, the return is pulling in unfiltered attic air. A failed joint is the likely cause.
• Condensation or wet spots on ductwork. Damp duct in a hot attic means the vapor jacket has failed. That’s a replacement call sooner than later.
• Visible damage in the attic. If you’ve had a roof replaced or a plumber in the attic, walk the duct run and look for crushed sections or tears. A five-minute look can save a call.

Our Process, Step by Step

1. 1
   Walk the system. We start at the air handler and work outward through every run we can reach, looking and photographing. We check the filter housing, the plenum, and the accessible trunk before we quote anything.
2. 2
   Test the pressure. We measure static pressure at the air handler and check for leakage at the visible joints. This tells us whether we’re repairing a leak, replacing a run, or looking at a bigger problem.
3. 3
   Put together the written estimate. You get the scope, the price per run, and the reasoning. We don’t quote less than the job needs to win the call.
4. 4
   Do the work with containment. We set up Abatement Technologies containment and filtration while we work so dust and debris stay out of your rooms. Rotobrush and Nikro equipment handle the brush work and fine particulate capture.
5. 5
   Walk it with you and photograph the finish. We take before-and-after photos of every repair, show you the finished work, and note anything else we see that you should watch.
