Common Questions
Do I need a panel upgrade for an EV charger?
Not always. We calculate your available capacity first. If your panel needs an upgrade, we quote both options so you can decide.
Which EV charger brands do you install?
All major brands, including Tesla, ChargePoint, Emporia, and Wallbox. If you already bought a charger, we install that too.
Do you pull the permit and handle the inspection?
Yes. We pull the permit, complete the install, and handle the city inspection. Before we leave, we walk you through your new charger.
What is the difference between Level 1 and Level 2 charging?
Level 2 charging runs on a 240-volt circuit and adds about 20 to 30 miles of range per hour. A standard household outlet charges much more slowly.

Yes. We install Tesla Wall Connectors and NACS-ready equipment, plus J1772 stations that work with adapters for every vehicle on the road.
Do you install chargers for businesses and apartment buildings?
