This company is top notch from beginning (quote) to end (my beautiful new tankless water heater). I had a 1998 (yikes!) gas hot water heater that needed to be replaced. John thoroughly inspected the situation, and even though I had complications with my existing gas line, he was able to offer me a very creative option that saved me greatly! They worked me into their schedule quickly and the installation crew was professional and meticulous. Highly recommended!
