Yes that's what it looks like, with the window units it's like who can make the cheapest one in compliance with government energy standards.
Wife doesn't mind spending the $ on a 2 ton inverter split.
We're looking at ones on ebay with 20 and 21 SEER rating. Since it will be quieter and use less energy than a window unit.
20 to 21 SEER seems to be the normal rating for the larger 2 ton and up inverter units.
I have never heard of or seen a window unit that does something more advanced than just turn on and off.
