You are one county north of our shop, straight up the I-35 corridor — the route we run most days.

Homes here run a wide range of ages, and it is common to find a system that has been repaired around rather than replaced.

We size to the house with a load calculation rather than matching whatever tonnage was there before, which is often wrong on an older home.
