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 San Marcos home.

Whole-Home Surge Protection in San Marcos

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

Why It Matters on the ERCOT Grid

Texas operates its own grid, and that independence brings more frequent voltage transients than interstate grids. For San Marcos 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 San Marcos home.

Why San Marcos Homes in Particular

With Texas State driving a huge rental market, a lot of San Marcos houses have had maintenance put off for years. Filthy ductwork, filters nobody changed since the last lease, AC sized for a family but cooling a house packed with roommates. We get rentals back to honest working order and tell landlords the truth about what is worth fixing.

Whole Home Surge Protection in San Marcos — 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 San Marcos 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 San Marcos 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.

“Bought a 1920s home near the Square and the wiring was a patchwork. Moorhead brought it up to code, kept all the original charm, and pulled the permit. They clearly respect old houses.”

Eleanor B.
San Marcos, TX

“I manage rentals by the university and Moorhead is the only crew that tells me straight what needs fixing and what does not. Saved me from a new system a tech at another company swore I needed.”

Greg P.
San Marcos, TX

“Our house by the river was always muggy. They added a dehumidifier and sealed the ducts, came up from Seguin same week, and the price matched the quote exactly. Comfortable for the first time.”
