An in-ground geothermal heating and cooling system for a building is provided. The system can include a buried ground source heat pump, a heat exchanger, and a ground loop circuit buried to a depth below the regional frost line. The system can also include a buried ground source heat pump buried inside a building to be heated. The system can also include an in-building heat exchanger disposed in a building, and an evaporative loop running from the ground source heat pump to the in-building heat exchanger. A method for installing such an in-ground geothermal heating and cooling system is also provided.

What is claimed is: 1. An in-ground geothermal heat exchange system comprising: a housing comprising a removable lid, the housing being sealed water-tight, reinforced to withstand ground force pressure, and positioned in a recess in surrounding ground having a regional frost line; a ground source heat pump disposed in the housing, comprising a heat exchanger, a compressor, a water pump, and a reversing valve, wherein the heat exchanger and the water pump are disposed in the housing below the regional frost line, and the compressor and the reversing valve are disposed in the housing above the regional frost line, each of the compressor and the reversing valve being positioned such that when the removable lid is removed from the housing, the compressor and the reversing valve are accessible from above the housing; a buried ground loop circuit comprising a portion disposed in the housing, wherein the portion in the housing is positioned entirely below the regional frost line and is in operable communication with the ground source heat pump, the buried ground loop circuit being adapted to collect and disburse ground source heat; an in-building heat exchanger disposed in a building; and an evaporative loop running from the ground source heat pump to the in-building heat exchanger. 2. The system of claim 1, wherein the heat pump comprises an air conditioning unit. 3. The system of claim 1, further comprising an evaporant disposed in the evaporative loop. 4. The system of claim 1, wherein the compressor comprises a scroll-type compressor. 5. The system of claim 1, further comprising a pump adapted to circulate a liquid through the buried ground loop circuit. 6. The system of claim 5, further comprising a liquid disposed in the buried ground loop circuit, wherein the liquid comprises water. 7. The system of claim 5, further comprising a liquid disposed in the buried ground loop circuit, wherein the liquid comprises anti-freeze. 8. The system of claim 1, wherein the buried ground loop circuit comprises a recirculating closed circuit. 9. The system of claim 1, wherein the buried ground loop circuit comprises piping. 10. The system of claim 1, further comprising an evaporant in the evaporative loop, wherein the evapormnt comprises at least one of halomethane, chiorofluorocarbon, hydrofluorocarbon, hydrochiorafluorcarbon, liquid ammonia, propane, butane, carbon dioxide, and combinations thereof. 11. The system of claim 1, wherein the in-building heat exchanger comprises an air-to-evaporant heat exchanger. 12. The system of claims 1, wherein the in-building heat exchanger comprises a liquid-to-evaporant heat exchanger. 13. A method comprising: forming a recess in ground having a regional frost line at a depth, the recess extending below the depth of the regional frost line, the ground having a surface; positioning a housing in the recess in a position such that at least a portion of the housing is disposed below the regional frost line; positioning a ground source heat pump in the housing, the ground source heat pump comprising a heat exchanger, a water pump, a compressor, and a reversing valve, the ground source heat pump being disposed in the housing such that the heat exchanger and the water pump are positioned below the regional frost line, and the compressor and the reversing valve are positioned above the regional frost line; positioning a water to evaporant heat exchanger below the regional frost line; and installing an evaporative loop from the ground source heat pump to an inside of a building. 14. The method of claim 13, further comprising selecting a length of a neck from a plurality of different lengths, the length extending from the surface of the ground surrounding the recess to the housing, and attaching a neck having the selected length to the housing. 15. The method of claim 14, further comprising circulating an evaporant through the evaporative loop from the ground source heat pump to the inside of the building, and back, wherein the evaporant is in the form of a liquid in at least a portion of the evaporative loop. 16. The method of claim 13, wherein the heat pump comprises an air conditioning unit. 17. The method of claim 14, wherein the positioning a ground source heat pump further comprises passing the ground source heat pump through the neck after the neck has been attached to the housing. 18. The system of claim 1, wherein the ground source heat pump further comprises an accumulator disposed in the housing above the regional frost line and being positioned such that when the removable lid is removed from the housing the accumulator is accessible from above the housing. 19. The method of claim 13, wherein the ground source heat pump further comprises an accumulator disposed in the housing above the regional frost line.
