"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"
