As I'm approaching 15 years on a couple of my A/C units and watching my utility bill grow out of sight, I'm wondering if it would be worth the trouble to put in a geothermal system. A lot of times in the winter, if I work in the barn, I'm heating over 14,000 sq. ft. of indoor space with my house, pool house and the barn. Needless to say, I try to burn the heck out of wood, but I have a feeling that doing so will eventually get old. I've heard some really unbelievable stories about how great geothermal is.
An advantage I have is that I have access to a boaring machine that can run all the underground portion for me without digging up my yard. I'm told by an HVAC guy that putting a coil in the deep end of my lake (about 18-10 feet) would make cooling easy for me. Thoughts, suggestions?
