“Old home with no ducts in half of it. They put in a mini-split and it is finally comfortable without tearing into the walls. Smart, careful work.”

Right-sized, not oversized
An oversized AC short-cycles, never pulls the humidity, and wears out early. An undersized one runs forever and never catches up. We measure your Castroville home — square footage, windows, insulation, ductwork — and size the system to it.
Then we quote it in writing, all-in, before any work starts.
Call (830) 587-5790A new system is a 15-year decision. Here is how we make sure yours fits your Castroville home instead of the installer's schedule.
We run a proper load calculation, not a rule-of-thumb guess off the old unit's label. Half the systems we replace were oversized to begin with — which is exactly why the house felt clammy and the bills ran high.
You get the price in writing before we start — equipment, labor, permit, and haul-off of the old unit. No "starting at," no surprise add-ons when the truck shows up in Castroville.
A higher-SEER system can meaningfully cut the cooling side of your bill through a Medina County summer. We show you the real payback math and let you decide — we are not working a quota.
If your system is repairable and worth repairing, we say so. We are not going to push a $9,000 replacement on a unit that needs a $275 contactor. Replace when it is 10+ years old and the repair tops half the replacement cost — otherwise, fix it.
Old Alsatian homes with thick walls and steep roofs rarely have ductwork that reaches everywhere. A ductless mini-split adds real, zoned cooling without tearing into a historic structure — the right answer for a house that was never built for central air.



From the historic Alsatian district along the Medina River to the homes just outside it, we reach Castroville on the extended run. A few of the areas:
