"I cannot sing the praises of Ian and Power Forward enough! He is outstanding. The jobs he did for me were fixing a switch panel that was overheating, installing a new light fixture. replacing light bulbs on outdoor lights that are high up and installing timers for those outdoor lights. He showed up on time. He called to say he was on his way. He works very efficiently and is very clean. He was very respectful wearing a mask and wearing shoe covers. I called him back for an issue a month later that had nothing to do with what he did prior. It was a Saturday and he came right out for the issue. I was so surprised he was available on a Saturday. I will continue to use him for all my electrical needs and my family and friends will also be using him. He's fantastic!"
