Chris,
Better to spend the money on the enclosure and supplementary dehumidification in Florida. The problem with ground source heat pumps is the install cost is too high. I’m heating and cooling a 4000 sq ft house in Texas with a 2.5 ton 13.6 SEER unit for 5-600$ per year. There is no way to justify the extra 1,000+$ per year in install cost for the 150$ a year in savings. That money would be better spent on the enclosure or photovoltaics.
That ignores the issues of potential pump failures and I have also seen wells fail due to ground water levels. That issue can cause loss of cooling for a long time. I wouldn’t let friends or family go that route without a big lecture and waving of hands.
