What Cupertino customers say
★★★★★We needed a Tesla charger installed before our car arrived. They handled the permit, ran the circuit cleanly through the garage and tested everything with the car. Highly recommend in Cupertino.
★★★★★Our restaurant lost power to the walk-in on a Saturday night. They came out fast, replaced a failed breaker and got us reopened. Saved a lot of food and a lot of stress.
