Duct Repair
In a typical North Texas home, the ductwork runs through an attic that reaches well over 140 degrees in July. Every gap, failed seam, and disconnected run in that system is either dumping the cooling you paid for into that attic or pulling superheated air back into your house. Duct repair is the least glamorous work we do and frequently the most cost effective.

Duct Repair in Rowlett, TX and the Dallas Metroplex
Duct leakage is the problem homeowners almost never suspect, because the symptoms look like equipment failure. The upstairs will not cool. One bedroom runs warm no matter what the thermostat says. The electric bill climbed but the system seems to be running fine. Those complaints send people shopping for a new air conditioner when the equipment is often perfectly healthy and the delivery system is the failure.
It is a widespread issue rather than an unlucky one. Industry studies have long put typical residential duct losses in the range of 20 to 30 percent of conditioned air, and homes across Rowlett, Rockwall, Garland, and Forney with attic mounted systems and flexible ductwork sit right in the middle of that. Sealing that up recovers cooling you are already paying to produce.
What Is Duct Repair?
Duct repair is the diagnosis and correction of physical problems in the duct system: leaking joints, failed connections, disconnected or crushed runs, damaged insulation, and undersized or poorly routed sections. It also covers sealing, which addresses the many small leaks distributed across an otherwise intact system.
This is distinct from duct cleaning, which removes dust and contamination from the interior surfaces. Cleaning addresses what is inside your ducts. Repair addresses whether the ducts are actually delivering air to your rooms. When homeowners have budget for one and not both, repair is almost always the better spend.
Common Duct Problems We Find
The difference between real duct cleaning and the version that generates complaints is method. A vacuum hose pushed a few feet into each register does essentially nothing.
Disconnected and Crushed Flex Runs
Flexible duct is held to its connection points by a strap and mastic, and over years of attic heat cycling those connections fail. A fully disconnected run means an entire room is getting nothing while your system pumps cold air into the attic, and homeowners typically discover it only because one room stopped cooling. Crushed and kinked runs are just as common: flex duct that has been stepped on by another trade, pinched against a truss, or left in a sharp bend that strangles airflow to a fraction of design.
Leaking Joints and Failed Tape
The classic North Texas duct failure is standard duct tape, which despite the name was never appropriate for ductwork and dries out and releases within a few years in an attic. Boots at the ceiling, plenum takeoffs, and every joint in the trunk line are all candidates. Individually these leaks are small. Distributed across a whole system they add up to the largest share of total loss.
Undersized Runs, Poor Design, and Missing Return Air
Some duct systems were never adequate. Runs too small for the rooms they serve, trunk lines that were extended to feed an addition without being resized, and insufficient return air are all design problems rather than damage. A system starved of return air cannot move the volume it was built to move regardless of how healthy the equipment is, and it creates pressure imbalances that pull attic air into the living space through every gap in the ceiling.
Why Leaking Ducts Cost So Much in North Texas
You Are Cooling Your Attic
A supply leak sends air you have already paid to cool directly into an unconditioned attic. During a Dallas summer that space runs 140 degrees or more, so the loss is total and it continues every minute the system runs. Because our cooling season is long, the cumulative waste is considerably larger here than the same leak would cause in a milder climate.
Return Leaks Pull Attic Air Into Your House
Leaks on the return side are worse in a way that surprises people. The return is under negative pressure, so a gap there actively draws in the hottest, dustiest air available and delivers it to your system. That means higher load on the equipment, more dust through the house, and in some cases attic insulation fibers and odors coming in with it. It also undermines every filtration upgrade you might make, because the contamination is entering downstream of your good intentions.
Rooms That Never Balance
Uneven temperatures between rooms and floors are usually a duct problem rather than an equipment one. Homeowners respond by lowering the thermostat to force the difficult room into range, which overcools everywhere else and raises the bill further. Repairing the delivery problem fixes the comfort complaint and the cost at the same time, which no amount of thermostat adjustment can do.

Repair, Seal, or Replace Your Ductwork?
Most systems need repair and sealing rather than replacement. Specific failures get repaired: reconnecting and re-strapping loose runs, replacing crushed sections, rebuilding failed boots, and correcting insulation. Distributed small leakage gets sealed, using mastic on accessible joints, which is the durable solution rather than tape.
Full duct replacement is worth considering when the ductwork is original to an older home and has deteriorated throughout, when the original design is simply inadequate for the house as it exists today, or when there is contamination that cannot reasonably be cleaned out. It is also the natural moment to do it if you are already replacing the equipment, since the labor overlaps and the disruption happens once. If you are weighing an AC replacement, have the ductwork evaluated as part of that decision rather than after.
Signs Your Ducts Need Attention
- One room or the entire upstairs never reaches the temperature the thermostat is set to
- Cooling bills that climbed without a corresponding change in weather or usage
- Weak airflow from some registers and strong airflow from others
- Visible dust blowing from supply registers when a cycle starts
- Rooms that stay dusty no matter how often you clean
- Whistling or roaring noises from the duct system during operation
- Visible gaps, hanging insulation, or disconnected flex where you can see ductwork in the attic
- The system runs constantly during the hottest part of the day but the house stays warm
