Tris was assigned to replace our old water heater to a tankless system. From the initial consultation to the installation he was very courteous and professional. He is very knowledgeable of the different tankless systems and took the time to thoroughly explained the process and cost which helped us select the best system for us. Once the install was completed he provided training/review of how to use the Rinnai control app. I will surely recommend Bill Howe to my friends and will use their service again if needed.
