Paul, Why is that bad? I thought ground-source HVAC systems worked better if the ground was saturated with water. Better thermal conductivity than dry soil. My problem finding someone to install a ground-source system was that everyone for miles is on city water. You have to be able to drill a hole in the ground and the folks familiar with well-drilling equipment are three hours away. Regards, Bill Herrin -- William D. Herrin ................
