“Put in a Generac after we lost power and water during a storm. They sized it for the well pump too, which the other quote ignored. Worth it.”
Leaky ducts can dump 20 to 30 percent of your cooling into a Marion 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 Marion 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 Guadalupe County summer and how we do it.
Duct joints, boots, and connections loosen over time — clay-soil movement in Marion 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 Marion summer.
Out past the town center, a downed line can mean hours in the dark and a well pump with no power. We are an authorized Generac dealer and size standby units to carry the AC and the pump, not just the essentials. Prices published before install.



From the town center to the new subdivisions on FM 78 and the rural acreage all around, Marion is a regular stop for us. A few of the areas we cover:
“Put in a Generac after we lost power and water during a storm. They sized it for the well pump too, which the other quote ignored. Worth it.”
“Our farmhouse outside Marion kept tripping when the AC kicked on. Moorhead found the panel was shot, replaced it, and pulled the permit. Fair price and they did not look down on an old country house.”
