Air Conditioner/Furnace/Tankless heater

Judith Denney from St. Thomas
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.

St. Thomas resident Barry gave us his feedback on his experience with Reliance:

“Right in the middle of the heat wave, our older air conditioner died. We called Reliance because they had a great deal. The Reliance sales rep Dean was honest and presented all the options with no pressure, and we moved forward because he presented an option that works well for us. It made sense to replace the 14 year old equipment (Furnace as well) rather than patch it up. Thanks Dean!”
