Hello, Selling out portable AC unit. I can't find the BTU spec but it is designed to cool an apartment or room. We have owned it for 5 years and only used it a few weeks a year when it gets hot. We are selling because we bought a new house and it has central AC. The unit has a plate that fits into a window or a patio door for the exhaust heat. Still have the instruction manual and the remote control for it.
