I bought to replace my 5 year old AC, same size, BTU's, damaged in Hurricane Ike. I love the remote, all the features, like energy saver, sleep mode, and easy clean filter with light to remind me when to clean. My prior A/C, also an energy saver cost me about 25% more to operate, even with the hottest, biggest drought in recorded history for Houston, Texas in 2011. It cools my shotgun style open rooms from Den, D/R, Kitchen, to L/R. My former one did not do this, but this one cools it all well on the Energy Saver!
