“Our Alsatian home is a landmark and we were terrified of someone wrecking it. Moorhead modernized the wiring with real care, kept everything original-looking, and pulled the permit. Rare to find that respect.”
Heat pumps fit Castroville's mild winters and long summers well — one system for both. We size, install, and service them right, including the propane-to-heat-pump conversions common out in Medina County.

One system, both seasons
South Texas rarely gets cold enough to need a furnace for long, which makes a heat pump — heating and cooling in one efficient system — a strong fit for many Castroville homes.
We run a real load calculation, size it correctly, and quote it in writing before we start.
Call (830) 587-5790Whether you are replacing an aging system or converting from propane, here is how we approach heat pumps in Castroville.
A heat pump handles both heating and cooling, and in a Castroville climate that runs more cooling than heating, the efficiency adds up. We size it to the home, not to a label, so it is not oversized and short-cycling.
When a heat pump will not heat or cool, it is usually the reversing valve, the defrost control, or the charge. These are different from a furnace fault, and we diagnose them properly rather than treating it like a straight AC.
Out on Medina County acreage, swapping an aging propane furnace for a heat pump can cut the fuel bill and simplify the system. We handle the conversion and the electrical it needs under one license.
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:

“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.”
“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
