Hi dhermesc,

Sounds awful expensive for what you were quoted.

A ground source HP can either be wet, uses well water etc:, or dry uses the earth as a heat sink.

Ground temperature doesn't change very much yearly, 50� average 8ft deep, for most of the USA, and is why a GSHP works well and very efficient.

Sizing HP HVAC units is a big problem in the industry. Most units tend to be sized for the refrigeration side and not for the heating side. Some areas due to the radical temperature swings a split or piggy back unit is best.

Alot to consider to spec the correct unit system for a pictular area.

I went to Alaska one time to spec a 50ton refrigeration system in a area that never got above 60� with very little humidity. Thats the gov't at work for you.
