Like other folks - I hear good things. Two situations where it seems it might not work. If the ground is very cold or very warm. But if it is middling ... it seems to be a good deal. E.g., for me - the ground is generally much cooler when I need to cool. For my summer situation the delta T is at least 30 degF relative to the outside air. At 100 degF The ground is still warmer than the day time air. So for me, the energy savings is primarily in the summer but heat pumped into the ground under my house comes back to me in the winter. For me - it looks to be a better answer than A/C and heaters as separate units based upon published numbers. If I just pumped groundwater into my heat exchanger - it would be close to sufficient.
