Yes the Gree Terra 9K at 27 SEER is a wonderful unit for the bedrooms. I also have a 30K
LG-LS307HV3. When it is blowing max capacity at 770 CFM it also is a little noisy but its ability to put out quite a bit of warm or cool air makes me overlook that in the 1200 sq-ft downstairs which has 23 foot vaulted ceilings.
The downside is that LG just changed their mobile phone software for the wifi module rendering phone control inoperative for an indeterminate period of time.
