EV Charging

The San Antonio Guide to Installing a Home EV Charger

January 2, 20268 min read

You bought the EV. Now the wall outlet in the garage adds range at a crawl and you want real speed. A Level 2 charger is the answer, but only if the circuit behind it is done right. Here is what to know before you buy anything.

Level 1 vs Level 2

Level 1 is the standard wall outlet, and it adds roughly 3 to 5 miles of range per hour. Fine for a plug-in hybrid, painful for a full EV. Level 2 runs on a 240 volt circuit and adds 25 to 40 miles per hour, which means full overnight for almost anyone. Level 2 at home is the upgrade worth making.

Can your panel handle it?

This is the question that matters, and the one cheap installers skip. A Level 2 charger can draw as much as your whole air conditioner. Before we quote, we run a load calculation on your panel. If there is room, great. If not, we price the options honestly, from load management that shares capacity to a service upgrade that adds it.

Plug-in or hardwired?

  • Plug-in units use a 240 volt outlet and are easy to swap or take with you.
  • Hardwired units support higher continuous output and give a cleaner install.
  • For most drivers who want maximum speed, hardwired on a properly sized circuit wins.
  • Either way, the circuit and breaker must be sized to the charger, not guessed.

Where it goes and how it runs

The distance from your panel to the parking spot drives a lot of the cost. A charger on the same wall as the panel is a short, cheap run. A charger across the garage or on an exterior wall means conduit and labor. We route it clean, keep it tidy, and label the breaker so the next electrician knows exactly what it is.

Permits and doing it right

EV circuits often require a permit and inspection, and that is a good thing. It means a second set of eyes confirms the work is safe. We handle the permit, the install, and the inspection, and we quote the whole thing flat before we start.

Tell us your car, where you park, and where your panel is. We will size it right and get you a flat quote. Then you charge at home like you should.
