The Service Manager, Mike Krejci, made an appointment to come to our house to discuss options for installing a tankless water heater. He was prompt, neatly dressed and well spoken. We decided to have the system installed. Dan Ranallo and Jeff (sorry I don't have a last name) were the installation Team. They arrived promptly at the appointed time. They were very courteous. They kept the noise level to a minimum. They answered any questions I had. They completed the job in one visit. Finally, they left the work site cleaner than they found it. It was like nobody had been there...except we had hot water!!!
