Incredibly efficient and super comfortable

We went from a great Carrier 5 stage furnace to this new heat pump because we wanted to go all electric. The performance has been phenomenal both in summer and winter. Our energy bills are way down and the house is always the right temperature. The humidifier also doesn't have to work as hard as it did with the furnace.
