If your Castroville home still has a Federal Pacific or Zinsco panel, your insurer probably already knows. We replace them, size the upgrade to your real load, and pull the permit.

Permitted + inspected
Federal Pacific and Zinsco panels — common in Castroville homes built from the 1950s through the 1980s — have a documented failure-to-trip problem, and carriers increasingly refuse to cover them.
We replace the panel, size the new service to your actual load including AC and any EV charger, and handle the permit and inspection.
Call (830) 587-5790A panel upgrade is not glamorous, but it is the spine of a safe, modern home. Here is when Castroville homes need one.
These panels can fail to trip under a fault — a real fire risk and a reason insurers balk. If you have one, replacing it is one of the highest-value safety upgrades in the house. We document it with a permit so it is on record for resale.
A lot of older Castroville homes run a service that was fine for 1970 and is overwhelmed by central AC, a modern kitchen, and a charger. We size a 200-amp service to what your home actually draws now.
Being licensed for HVAC and electrical, we size the panel to carry the AC properly — the part panel-only electricians often get wrong. The breaker box and the condenser are the same job to us.
Every panel upgrade gets the local permit and inspection, wired to NEC 2023. It protects you, it is required, and it is the difference between a real upgrade and a liability hidden behind a cover.
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:
“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
“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.”
