Jeremy and his partner were great. They setup the thermostat program, showed me how to use the thermostat, explained how my new furnace which is a Rheem 80% efficiency unit works, what type filter I will need and how often to change filter. Went over eveything. Very professional putting down carpet protector and wearing shoe coverings and cleaning up afterwards. Overall very pleased with how fast and smoothly everything went. Before they left they answered my questions.
