Most efficient AC unit available for Central Florida

[jermrief]

Hello,
We are in the process of building a 60'x120'x16' metal building for our personal shop in Central Florida. We plan on insulating and cooling to 76-80 degrees. We won't heat in the "winter". The shop will be located on a wooded acreage. The property currently only has single phase power, but we might consider adding three phase based on cost to install. We estimate we will need a 10-15 ton unit (not set in stone). So if we only have single phase, will need to run 2 or 3 units.

What is the most efficient cooling unit we can install? Geothermal Heat Pump? Split-Unit? What model/brand? Dual Stage? We are more focused on efficiency then cost. A FHP ES 2 Stage Geothermal and a Daikin Split-Unit that is SEER 26 (even though it only goes to 15K BTU) has caught our eye. Also, we are very DIY so would like to do as much of the work ourselves (running geothermal tubing ourselves for example)

Thanks

The climate master tranquility inverter geothermal unit is the best on the market I believe at around 40EER with variable capacity. You would probably need 2 or 3 though and they are pricey.

Lennox has some package units in the 10-12.5-15 ton range which operate at higher SEERS than most package units... nothing like geo though. Plan on 3 phase unless you go with residential sized geo.

Now here is a question: Will this be an open shop, or divided rooms? If it is rooms, then you might look at a multi-head mini setup... like Daiken or Mitsubishi city. Can get higher tonnage with good SEERS.

Depends on what your doing in the shop, and how many people. 15 tons may not be be near enough. A load calc should be done.
