“On a well out in the county and the power drops a lot. They sized a generator for the pump and AC. Worth it, and they gave a real window.”
If your Karnes City 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 Karnes City 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 Karnes City 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 Karnes City 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.
The established homes near the courthouse often run undersized panels and dated wiring. We modernize the electrical safely, keep the character, and bring it to NEC 2023 code with a permit.

“Boom-era house and the AC never kept up upstairs. Moorhead measured the load and fixed the airflow instead of selling a whole new system. Honest about the drive and fair on price.”
