My first Gree has been installed for a while now.. Fall of 2016..

I have not purchased one for the den yet. The den Sanyo is a problem below -12C.
So, I'm waiting for the climate to turn warmer, or the noisy fan motor to die..
Then, I'll likely buy a second Gree.. This one has worked okay at -20C.. (-5F)
