i'm thinking about getting a geothermal heat pump but have no idea what brand is best .
i think about 36,000 BTU's (3 ton ) will do the job as thats about the size furnace i have now .
it will be hooked up as Horizontal closed loop system.
i'm looking at a Mcquay Geothermal Heat Pump, FCW-1036.
any one have any good brands in mind ?
