St. Thomas resident Judith Denney gave us her feedback on her experience with Reliance

RHC advisor Dean came to our home to assess the feasibility of a tankless water heater. With his easy manner and apparent knowledge he also showed us the benefits of replacing our dated furnace and AC with an energy efficient system. We felt no pressure to make a decision. I am happy to say our new furnace/ AC and water heater will be installed on Monday. Thank you Dean.
