Leaky ducts can dump 20 to 30 percent of your cooling into a Devine 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 Devine 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 Medina County summer and how we do it.
Duct joints, boots, and connections loosen over time — clay-soil movement in Devine 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 Devine summer.
Devine is out on our extended map southwest of San Antonio. We give you a real scheduling window rather than overpromise, and the same flat-rate honest work we do at home. Call to confirm and we will tell you when.



From the town center to the fields and ranch acreage along IH-35, we reach Devine on the extended run. A few of the areas:
“Old panel on a long run, flickering lights. They diagnosed the voltage drop, upgraded the panel, added surge protection. Knew their stuff.”
“Farm outside Devine on a well, power out every storm. Moorhead sized a Generac for the pump and AC. Never lost water again, and they were honest about the drive from Seguin.”
