"We hired Alex to install can lights in our dining room. The price was extremely reasonable and they were able to fit us in within a week of when we received their quote. They arrived promptly, installed in a couple hours and had the room as clean as it was when they arrived. We plan on using Power Electric again to upgrade our fuse box and also to hang more lights. Very pleased with the overall experience. Highly recommend!"

"Ariel installed 50 amp inlet to my breaker box for portable generator. He completely cleaned up the breaker box. Separated rooms to different breakers so I can turn off rooms i don't use. He was extremely thorough in his work. Upon finishing installation, Ariel stayed on his own time and explained everything i needed to know about using generator and which breakers to use if i have a power outage. He was very knowledgeable and made sure i understood before he would leave. I highly recommend ACG based on my experience with his work ethic. Thank you Ariel!"
