"When I made the request on Angi's List, Gonelectrical called me within seconds. We talked about installing a whole-home surge protector. I traded some photos of my panels and received a quote over the phone. The job was scheduled for the next day. They showed up promptly and completed the work professionally. They explained what they did and showed me exactly what was done. I would recommend this company for similar work."

"Josh and his team are THE BEST: professional, prompt, caring, thorough, kind, and really Christ-like in every way. They communicate better than any other business I've encountered. I strongly recommend them . I had been told that it would take six months to get a generator. Josh understood my need and got to work on it, immediately. They installed a generator within three weeks. I'm so grateful for them. N.C."

"I have zero complaints about this company. They came out very quickly to access my issue. It was urgent. From Oncor and this company, I clearly escaped what could have been a major fire. These guys were so professional and kept me in the loop of everything being done. I've saved their number for any future issues and I will definitely recommend them to anyone needing a skilled electrician. It was worth every penny to have it done professionally and safely. Thank you ALL."
