Jersey, where in Ga do you live? I'm originally from South Atlanta/East Point. You mean to tell me there's no humidity where you live in Ga? You must be in the mts. Or that you don't have a problem using the geothermal in high humidity? We will probably have a 2 ft overhang over the glass. Glad to hear somebody local say '100.00 power bill'!! That's my game plan. I have a dumb question ...when the geo people come and install everything, does that include the unit that goes inside too? I assume you have to have all the ductwork already installed. What exactly do you have to provide and what do they provide?
