High(est) efficiency air source heat pump?

Hi,

My Mom got some information on a Fujitsu heat pump that has an HSPF rating of 12-12.5 and a SEER rating from 25-27.2, depending on the capacity. The smallest is 9,000BTU cooling and 12,000BTU heating, and the largest of three models has ~14,000BTU cooling and 18,000BTU heating. They are single zone, and the multi zone units the ratings drop to ~9 and ~20 respectively.

Wall Mounted 9 - 15,000 BTU Hi SEER - Fujitsu Ductless Mini-Splits

What is the competition on these? How close is this efficiency to ground source heat pumps?

I have a 9' x 22' screened porch on the east side of the house, and it has a tall (4'-8"-ish) crawl space with stone walls and a dirt floor. What would prevent this from being a good place to locate an outside unit of these split systems?
