It arrived sooner than expected. The unit itself was mishandled by FedEx upon final delivery from North Bay as it was laying down. The bottom of the box was damaged as well as the foam inside.I am happy to report that the unit itself was not damaged and after letting it stand up for 6 Hrs it functioned normally thank the Gods for that. The weather here is still cold so I used the heater mode and it functioned quite well considering it is just an air to air heat pump. The cooling mode works but hard to tell how well just at the moment. I have no complaints at the moment but time will tell. I have casement windows so I built a 6 inch deep insert which sits in the window frame with screen on the outside and plexi-glass on the inside where I attached the hose ends.I had an Emerson Quiet Cool window air conditioner previous to this that lasted me 36 years,so we will see how far this Whynter goes. Treat it right it will probably outlast me.
