Duct Repair & Sealing in Plano, TX
Duct repair and sealing in Plano, Texas. We mastic-seal leaky joints, re-support sagging flex duct, and fix undersized returns so your far rooms finally cool. Built for Plano's 20-to-30-year-old homes.
The Real Reason Your Far Rooms Won't Cool in Plano
Plano is one of the oldest, most established suburbs in Collin County, and a huge share of its homes were built 20 to 30 years ago. The AC equipment gets replaced, but the ductwork in the attic usually doesn't. After decades in 130-degree summer attics, the cloth tape on the joints dries out and peels, flex duct sags and crushes, and register boots pull loose. The result is a system that runs fine near the unit but leaves the back bedrooms hot no matter how low you set the thermostat.
We test static pressure, find the leaks, and seal them with mastic that actually survives the heat. If duct loss is dragging down a tired system, it can also mean your AC was sized to overcome those leaks — worth knowing before you plan an AC replacement. Leaky returns also pull attic dust into your air, so this often ties into indoor air quality too.
What Goes Wrong in Older Plano Ductwork
Hot Attic, Leaky Supply Runs
In Plano's 25-year-old homes, supply ducts run through attics that hit 130-140 degrees in summer. Every gap pulls in that superheated air and dumps cooling before it reaches the room.
We seal joints with mastic (not tape, which dries out and falls off) and re-insulate exposed runs
Sagging & Crushed Flex Duct
Original flex duct in older Plano homes sags, kinks, or gets crushed under attic storage, choking airflow to the far bedrooms.
We re-support, straighten, and replace collapsed sections so air actually reaches every register
Undersized & Leaky Returns
Many 1990s-2000s builds were value-engineered with one undersized return. Leaky return boxes then pull dusty, hot attic air straight into the system.
We seal return boxes and can add or enlarge returns to fix high static pressure
Disconnected Boots & Plenums
Register boots pull loose from drywall and plenum connections separate over decades, leaking conditioned air into walls and the attic.
We reconnect and seal boots and plenum takeoffs so you stop paying to cool the attic
