This A/C has been an absolute life saver. Before this purchase we had 4 5000btu A/C's in our home and our home would still be 85 degrees when we got home from work after a long hot day. We broke down and spent the money to get this large A/C and this is the only one we have to run. It keeps my whole house cool. It has saved us more than we paid for it, on our electric bills in one summer.
