I just had one of these installed last week:
Fujitsu 12RLS - 12000 BTU 25 SEER/12 HSPF heat pump
Good specs and the warranty in Canada is 10 years on the compressor, parts and labor.
I'm going to be setting it up with the ground loop and a blower for next winter. The 3000 kWh a month we've had this winter have been bad enough.
