$200. Wow, that’s cheap for a new roller AC unit, low capacity as it is. But be careful about those 11,000 reviews at Woot mother Amazon - only about 500 of them appear to be for this unit. So filter down to this unit’s review and read.
Obligatory caution that single hose roller AC units are a horribly inefficient way to cool a room/house. Unless you don’t care that by using this unit, you’re sucking hot humid outside air into the home somewhere else. That single exhaust hose is sending the extracted heat from the room air out the window and that same exhaust air must be “made up”/replaced by leaks from the outside somewhere else in the house. Additionally, having all the hot bits inside your room + the hot exhaust hose “leaks” that heat right back into your room.
There’s a reason the Department of Energy (DOE) finally up with the roller AC makers and forced them to down-rate the real world BTU ratings of these units. And yet the AC industry shamelessly continues to post their dishonest higher BTU claims with their own official sounding acronym behind.
