“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.”
Most Castroville HVAC companies cannot touch your panel, and most electricians will not look at your condenser. We are licensed for both — so the crossover jobs get done in one visit.
Thanks for reaching out. We've got your request and we'll be in touch shortly, usually the same day. Need us right now? Call (830) 587-5790 — we're open 24/7.
HVAC + electrical, one license
Panel upgrades, EV chargers, surge protection, generators, lighting, dedicated circuits, code corrections — the full residential electrical scope, handled by a licensed crew in Castroville.
And because we are an HVAC company too, the jobs that cross trades do not turn into two contractors and two trips.
Call (830) 587-5790From a dead outlet to a whole-home rewire, here is the residential electrical we handle across Castroville.
Panel upgrades, Federal Pacific and Zinsco replacement, new dedicated circuits, and rewiring older Castroville homes with aluminum or cloth-wrapped wiring. All to NEC 2023 code, all permitted.
Level 2 EV charger installs on a proper dedicated circuit, plus the panel capacity to support a pool, a shop, or a hot tub. We check the load instead of just landing a breaker.
Whole-home surge protection — genuinely worth it on the ERCOT grid — plus hardwired, interconnected smoke and CO detectors and the GFCI and AFCI corrections that bring older homes up to current code.
A failing AC tied into old wiring, a charger that needs a panel upgrade, a generator that has to carry the condenser — these are the jobs where one company licensed for both trades saves you a second visit and a second invoice.
The Medina River keeps Castroville humid, which is hard on very old homes. Whole-house dehumidifiers, duct sealing, and UV in the air handler protect both comfort and the historic structure from mold and swelling.

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:
“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.”
“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.”
