ClimateMaster geothermal compressor - $600 (Brodhead, WI)

ClimateMaster Tranquility 27 Two-stage EarthPure HFC410A geothermal compressor.
Used, in great condition.
Was in a home that was deconstructed to make way for what is now the Kelch Aviation Museum.
Compressor unit was professionally disconnected, drained and moved by Al Beyers Indoor Comfort Systems.
We purchased it intending for it to be an extender of our main system for an above-garage apartment, but after getting second and third opinions, that would be too much of a drag on our main unit.
It is a 3-ton unit with a fully encapsulated electric forced air furnace as part of the unit.
See photos for model and serial number.
Need to confirm but we think this unit is from the early 2000s.
