What We Do in Castroville

Every Service.
One Truck.

In a town of 1840s Alsatian homes, the AC problem and the wiring problem are usually the same age — so being licensed for both HVAC and electrical means one careful visit, not two. We treat historic homes like the landmarks they are.

We Know
Little Alsace

Justin and Levi Moorhead have run this company out of Seguin since 2009, and Castroville is part of our extended service area west on US-90. We know what its historic Alsatian homes ask for — careful modernization of very old wiring, comfort retrofits that respect the architecture, and the Medina River humidity that comes with the setting. Call to confirm a window and we will give you a straight answer.

Flat-rate quoted before we touch anything
You approve the price in writing first. If the job gets harder, that's our problem — not yours.
We tell you when repair is the right call
If the system's repairable, we say so. We won't push a $9,000 replacement on a unit that needs a $275 contactor.

When a job crosses trades, we handle it. No second company, no second visit.

1840s Architecture, Wiring to Match

Castroville's steep-roofed Alsatian homes go back to Henri Castro's 1844 colony, and they were wired — when they were wired at all — generations after they were built and generations before modern loads.

We modernize panels and wiring in these historic homes with real care, keep the character that makes the town a landmark, and pull the permit. Old-world charm, current-code safety.

What We See in Castroville Homes

Castroville is a historic Alsatian river town, so the work is mostly about preserving very old homes, retrofitting comfort carefully, and handling river humidity.

Historic Alsatian Homes

The 1840s and 1850s homes that make Castroville a landmark often carry undersized panels, knob-and-tube, and two-prong outlets. We modernize the electrical with real care, keep the historic character, and document it with a permit for insurance and resale.

Comfort Retrofits Without the Ductwork

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.

Medina River Humidity

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.

Honest About the Drive

Castroville is a real distance west on US-90. We give you an honest scheduling window rather than overpromise, and the same careful, flat-rate work we do at home. Call to confirm and we will tell you when.

Castroville Questions

Carefully and regularly. Those 1840s and 1850s homes often have knob-and-tube, two-prong outlets, and undersized panels. We modernize the electrical with real care for the architecture, keep the character, and pull the permit so it is documented for insurance and resale.
A ductless mini-split is usually the right answer. It adds zoned, efficient cooling without tearing into a historic structure with thick walls and steep roofs — comfort without compromising the house.
The Medina River keeps the humidity up, and old homes hold it. A whole-house dehumidifier, sealed ducts, and a UV light in the air handler cut the mugginess and protect the structure from mold and swelling.
Castroville is a real drive west on US-90, so we are honest about the window and will give you a real time rather than overpromise. Call to confirm and we will tell you exactly when.
Yes, under one license. In a town of 1840s homes the AC and the wiring are usually the same age, so we handle both in one careful visit instead of two companies.

“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.”
