I had an 8k BTU unit that finally died. I've always kept it set to 73 degrees. It would cool the room down but even on Energy Efficient it constantly ran.

But, this LG 12k BTU, well, what can I say. I wish I had bought this a lond lind time ago! Keep it at the same temperature and it cool off quicker, does not run as ofter, and has even lowered my electric bill by $15 a month! There have even been some times I've actually had to turn it off in the evening because it felt too cold, and I'm in Central Florida on the coast! HIGHLY recommend this product!
