We have had problems blowing fuses with our solar system since installing it 6 years ago. Contacted atoms and the walked me through the issues that the installer had created . Atom’s scheduled the repair for the following week. They came out when scheduled, performed the repairs as discussed and got our system back on line the same day !! We were only down a week , as compared to prior companies down a month to two months .. Highly recommend this company! Great work and great service ! In today’s world service is everything!!! Good people !

We reached out to multiple electricians to see about installing solar panels and all the necessary equipment to work with our Ecoflow power stations. We did not want to be hooked to the grid as we want emergency power and recharging capability even when the grid goes down. A lot of companies only work on grid-tied projects and others never bothered to get back with us. Atoms Electrical were very responsive and professional in evaluating the project, discussing alternatives and coming up with a plan. Fortuitously, Atoms Electrical is also a contractor for Ecoflow products. The project was handled in phases and included all the interaction with the governing authorities. All the employees are friendly, hardworking, maintain a clean area and respectful of the property. All in all, very professional and Adam is excellent at explaining the technical things to a non-electrician! Actually, all communication with the company is excellent and we were always kept informed. They show up when they say they will. In addition, between phases of the solar project, we needed some ceiling fans and lighting fixtures replaced. The response to this request was quick and handled well. We can highly recommend Atoms Electrical for your electrical needs and plan to have them back for another project once the heat in the attic dies down.

Had the team from Atoms come out to add ceiling lights in areas where none existed, along with installing a floodlight. The work was completed in a timely manner, and the crew was professional, courteous, and knowledgeable throughout the process. What I appreciated most was that they took the time to explain what they were doing as the work progressed, which gave me a lot of confidence in the project. They also did an excellent job cleaning up afterward. Honestly, I think my house was cleaner when they left than when they arrived! Very happy with the results and looking forward to having them back for future projects. Highly recommend.

Keith Henige

I had a huge arc/sparks from an outlet. Adam answered when I called and was at my location within the hour. He diagnosed the problem as wrongly wired neutrals and corrected the problem. He was very efficient. I liked how he answers the phone when you call. In fact he took a call while he was working in my kitchen. He also explained some issue that needed attention in order to bring my house up to code. All this, and he’s was very reasonably priced.

Andre Van Oyen

Atoms Electrical was sent as part of a home construction project. Zack and Jeff were professional and polite. Zack was very knowledgeable and we hired them directly to do additional work. We highly recommend Atoms Electrical and will use them again in the future.
