    Excellent customer service, very professional. 1st Gen installed a chandelier in my living room. He worked very efficiently and maintained great communication about the project. In addition he added can lights in my family room and replaced my old ceiling fan with a new modern one. Thank you 1st Gen for going above and beyond!

    The quality of the work was excellent—everything was installed cleanly and works perfectly. They were also very respectful of my space, keeping things organized and cleaning up thoroughly after the job was done. What really stood out to me was their attention to detail and commitment to doing the job right, not just quickly. It’s clear they take pride in their work. I would definitely recommend them to anyone looking for a reliable and skilled electrician. I’ll be using their services again in the future.

    I can’t say enough good things about the experience I had working with Jesus. From start to finish, he was professional, knowledgeable, and incredibly easy to work with. He installed a 400 amp automatic transfer switch for my generator setup, and everything was done cleanly, efficiently, and with attention to detail. Passed inspection immediately after his install. He took the time to explain the process, answered every question I had, and made sure everything was done safely and up to code. It’s not every day you find someone who combines skill, integrity, and great customer service the way he does. You can tell he genuinely cares about his work and his customers. If you’re looking for a reliable electrician who knows his craft and takes pride in what he does, I highly recommend giving Jesus a call. I’ll definitely be using him again for future projects.

    I’ve used 1st Gen Electric for two separate projects now, and they’ve earned a permanent spot on my go-to list. First, they installed a new outlet in my basement — quick, clean, and exactly where I needed it. But the bigger job was diagnosing and resolving aluminum wiring issues throughout my house. If you know anything about aluminum wiring, you know it’s not something to take lightly, and it’s not something every electrician handles well. 1st Gen Electric approached it methodically and walked me through the fix every step of the way. I felt informed rather than overwhelmed. What stood out most was the combination of technical know-how and honest communication. No upselling, no vague answers — just solid work and straight talk. My home feels noticeably safer, and that peace of mind is worth every penny. Highly recommend for anything from simple installs to more complex electrical problems. Great company, and extremely competitive pricing.
