It is so cold this week - I cannot believe our water heater went out!!!! My neighbor used these guys and there was one of their stickers on my tank. No complaints. I appreciated that they put everything in writing before beginning. They also put an expansion tank on the unit. I also liked that they took the time to explain to me what the expansion tank actually does. I was tempted to install a tankless but we had just replaced our furnace and we can't use the tax credit twice.
