    The electricians at STS Electric are simply top-notch. Francisco and Daniel were on-site and did a flawless job installing our new lighting. Sam’s supervision gave me peace of mind that everything was being handled professionally.

    STS helped when the circuit board blew on our rental. They were very communicative throughout the entire process, especially considering I couldn’t be there to check the work at the time. The final product was clean, well done and organized.

    Being first time EV owners, we had quite a bit to learn about the process of getting an EV charger installed in our home garage. Ana was very responsive and arranged for a same day in person consult. Our project manager, Sam, was both friendly and extremely knowledgeable, we appreciated that he took his time with us as we had many questions. After we decided to proceed, they scheduled us within the same week. Our electrician Francisco did great work and finished the project in one day. He even performed the drywall himself. Highly recommend this company!

    Hired STS Electric to address an electrical issue with our detached garage. They were prompt and professional. They came out the next day and addressed the issue with great detail. Sam was very professional and kept me up to speed throughout the process. Highly recommend STS for your electrical emergencies or projects.
