What's the tonnage on this Trane unit?
It does not look like a good number.
I checked and rechecked this number on 3 different data plates from both units that we have and it is the correct model number. If it helps this system is a geothermal system installed in 2011.
Nevermind, I found it on Trane's website using the literature search function: http://www.trane.com/webcache/un/wat...n_12152011.pdf
it is a 25 ton, unitary, water source heat pump.
