Otherwise, hard to answer your question without more information. What size space are you trying to cool? How are you cooling during a power outage?
The Midea U Shaped window Air Conditioner CEER is 14.5 to 15 and is Energy Star Rated.
The Hisense U Shaped window Air Conditioner CEER is 15 and is Energy Star Rated.
The Midea and Hisense (both inverter) are available at Costco and Amazon (on sale earlier this year and typically clearanced at the summer's end, if not sold out)
Your choice.
I have both Midea U (8K, 10K, and 12K) and Hisense U 8K. I prefer the Midea, but the Hisense is OK (lower profile, but slightly noiser). P.S. I have a large house with central air and use the window ACs to cool bedrooms at night or add cooling to living areas (I am retired and kids have grown up, moved out). HOA restrictions are the main hurdle.
UPDATE: I stand corrected by holysin. It's strange Best Buy's own ad / TCL would list a lower (incorrect) CEER rating and not advertise an Energy Star rating.
I have a 10ish year old 15000BTU unit that is responsible for a space that it does a decent job cooling. Its pretty much perfectly sized, even on a 100 degree day. I'd really like to replace with an inverter but haven't come across many 15000 BTU ones. A minisplit is easier said that done in the room.
Would a 12000 unit be woefully undersized? Or will the variable nature of it mean it can potentially handle a room that would have normally called for a larger traditional unit? Any guess on which way would be worse electric bill wise?
I replaced 2 other traditional a/cs with inverters a few years back, and went with similar sized ones to the ones they replaced, and they have no problem cooling the rooms far more than the old ones would have.
