 Trustindex verifies that the original source of the review is Google. I reached out to Quantum Thunder and a few other electricians about my need for an EV charger installed at my house. Andrei was extremely quick in replying, gave a great quote, and was up-front on expectations, costs, etc. The others I reached out to either needed over a week to quote me, refused to permit the work, or threw numbers at me that had no basis in reality. On install day, he was on time, extremely friendly, and did a quick and very clean job. No issues whatsoever during the install and he was appreciative of the work. I charged my car that night.

 Trustindex verifies that the original source of the review is Google. Quantum Thunder Electric did an outstanding job, and I can't recommend them highly enough. Andrei installed my Level 2 EV charger and the entire experience was smooth from start to finish.

The work itself is top-tier: a clean conduit run, a dedicated 240V circuit with a new breaker, proper grounding, and a tidy, weatherproof finish. Everything was done quickly without cutting any corners.

Andrei also handled the electrical permit and inspection coordination, so I didn't have to chase anything down. Communication was excellent the whole way through, from the initial quote to the final walkthrough.

Pricing was fair and fully transparent — no surprises. If you need an EV charger installed or any electrical work done, this is the team to call. I'd hire them again without hesitation. 5 stars!

 Trustindex verifies that the original source of the review is Google. I hired this electrician to complete several projects at my home, including an EV charger installation, electrical panel upgrade, installation of additional outlets, and a general inspection of the home’s electrical system.

From start to finish, he was professional, knowledgeable, and easy to work with. He took the time to explain the scope of work, answered all of my questions, and made sure everything was completed safely and up to code. The panel upgrade and EV charger installation were done efficiently, and the additional outlets were installed exactly where I needed them.

What I appreciated most was his attention to detail during the electrical inspection. He identified a few issues, explained the potential risks, and provided practical recommendations without any pressure.

The work area was kept clean, communication was excellent, and the project was completed on schedule. Finding a reliable electrician you can trust is not always easy, but this was a great experience.

I highly recommend him for any residential electrical work, whether it’s an EV charger, panel replacement, troubleshooting, inspections, or new outlet installations. I will definitely be using his services again in the future.

 Verified Andrei got back to me right away with a detailed estimate, and quickly came by to confirm the details and scope of work. He handled all the permit and inspection stuff which I was really worried about having to handle. I had contacted 3 different companies, and Andrei communicated quicker, gave me much more thorough estimates and info, and his price was the best. He got the bulk of the work done very quickly, and the only delays were having to wait for pre- and post-work inspections by the city. Zero complaints here - would totally work with him again.
