Geothermal heat pump
I am thinking of installing a geothermal heat pump. I have been told that because they are more efficient I dont have to have as large of unit. A standard load calc says I need a 3 1/2 ton ac unit and 75k btu out put furnace. I have been told I could get by with a 2 ton 26k BTU heat pump. I live in CT and it gets cold for week below 32 degrees. Anyu thoughts.
