Scott and Connor came out and fixed our hot water issues and replaced some old thermostats in the house. They were super professional, kind, quick, and helpful. G2 feels like one of the most honest and transparent companies I've worked with and I'm really glad to have them servicing my home. They immediately made me feel like a friend and I feel like I can really trust their service and advice. I definitely look forward to working with them in the future and I would highly recommend them to anyone. Also, my dog loves them too which is just bonus points.
