A friend of mine that lives out in the sticks uses a geothermal grid (tubing buried in the ground) to heat and cool his house (heat pump). The water circulating is a pretty constant 50 degrees year round in St Louis.
The freon is completely contained in the unit in the basement. Of course he has a pinhole leak in the condenser and is looking at $8000 to replace the whole aging unit.
