“On a well out in the county and the power drops a lot. They sized a generator for the pump and AC. Worth it, and they gave a real window.”
Leaky ducts can dump 20 to 30 percent of your cooling into a Karnes City attic that is already 140 degrees. Sealing them is one of the best dollar-for-dollar comfort fixes there is.

Stop cooling the attic
Most Karnes City duct systems leak at the joints, and every bit of conditioned air that escapes into the attic is money gone and a room that never cools. Sealing closes those leaks.
The result is more even rooms, a lower bill, and a system that does not have to run as hard.
Call (830) 587-5790Here is why sealing matters so much in a Karnes County summer and how we do it.
Duct joints, boots, and connections loosen over time — clay-soil movement in Karnes City does not help — and the leaks let conditioned air escape into the attic. You feel it as a hot back bedroom and a high bill.
We locate the leaks and seal them at the joints with mastic, and where the duct layout is buried or hard to reach we can seal from the inside. Then we verify the airflow improved rather than just declaring it done.
Sealing usually fixes the room that never cooled, because the air that was leaking out now reaches the register. It also takes load off the system, which extends its life in a Karnes City summer.
Karnes City is a real distance down US-181 from our shop. We give you an honest scheduling window rather than overpromise, and the same flat-rate work we do at home. Call to confirm and we will tell you when.

“Boom-era house and the AC never kept up upstairs. Moorhead measured the load and fixed the airflow instead of selling a whole new system. Honest about the drive and fair on price.”
