Easy installation, all parts were included. AC works well, however the heat output is very low. With the heat function on, the air coming from the unit does not feel much warmer than just having the fan on. with the unit running heat for 2 hours, the room temp only increased by 7 degrees. Disappointed as i already had a window AC unit, this was purchased to provide heat to a room and get rid of a space heater that was on the floor.
