Energy Star 12,000 BTU Window Mounted Inverter Air Conditioner with Supplemental Heat, Quiet High Efficiency Window AC Unit with Remote for Apartment, Medium-Large Rooms up to 550-Sq.Ft.

im trying to cool/heat 510sqf doubt it will do that but it blows very cold and is very quiet

Before purchasing this item I searched Amazon's site & called into them for product support to see if this item qualified for the P65 Warning & was told it was not. Although it is not required by law to declare this warning to the public in states other than California...most companies do the information available. When I received this a/c product the P65 Warning was clearly stated/labeled on the outside of the product box.

Great product!It’s enough to cool my 900 square foot florida home in the month of august to a comfortable 73fWorking out better then expected

Did not know what to expect but air conditioner works awesome ! Really cold I love it and would highly recommend it to anyone

This unit will not effectively cool 550 sq ft. It might cool half that. It never shuts off, and is set at 72. I suspect the heating function will be the same or worse. I wouldn't buy it again, and would like my money back. I returned for refund, and still waiting for it!
