The Spikes You Never See

Surges are not just lightning — most are small, frequent transients from the grid and from big appliances cycling, and on the independent ERCOT grid they come more often. Each one shortens the life of your electronics and HVAC boards.

A panel-mounted Type 2 protector stops them at the door for the whole Castroville home.

Whole-Home Surge Protection in Castroville

Cheap insurance against an expensive, invisible problem — here is how it works in Castroville.

Why It Matters on the ERCOT Grid

Texas operates its own grid, and that independence brings more frequent voltage transients than interstate grids. For Castroville homes that is a steady, quiet stress on everything plugged in, not just the rare lightning hit.

Protects the Expensive Stuff

Modern HVAC systems, appliances, and the panel itself all run on sensitive electronics. A whole-home protector guards the AC control board, the smart thermostat, and the rest — the repairs that cost far more than the device.

Panel-Mounted, Whole-House

A Type 2 protector mounts at the panel and protects every circuit, layered with point-of-use protectors for the most sensitive gear. We install and test it, and it is a quick, high-value job in any Castroville home.

Why Castroville Homes in Particular

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.

Whole Home Surge Protection in Castroville — Questions

On the ERCOT grid, yes. Texas runs its own grid with more frequent voltage transients than most of the country, and those quiet spikes shorten the life of your Castroville home's electronics and HVAC boards. A protector is cheap next to replacing them.
A panel-mounted Type 2 protector runs $250 to $375, or $325 to $450 for a premium unit on a generator or EV home — flat-rate, in writing, tested after install.
No — most surges are small, frequent transients from the grid and from appliances cycling, which is the bigger ongoing threat. A whole-home protector handles both.
Every circuit in the Castroville home — your AC control board, appliances, smart devices, and the panel. We often layer it with point-of-use protection for the most sensitive electronics.

“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.”

Margarethe B.
Castroville, TX

“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.”

Pierre L.
Castroville, TX

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