Living in a small loft with southern exposure, no central air, and large windows incompatible with traditional a/c units gets pretty darn hot in the summer. Multiply that by a record-setting triple-digit heat wave and it becomes absolutely unbearable! After 3 sweaty, sleepless nights- we broke down and decided to buy an a/c, but every store in our metro area was completely sold out. I'm glad. This unit has more BTUs and a better value than anything we could have bought locally. We ordered it on Sunday night and, to our glee, received it on Tuesday! (come to find out it was shipped from a warehouse in our city) My husband had it set up within 30 minutes or so and... instant relief! The temperature in our place went from 95 to 85 the first night. After a few days, we were down to a cool 75. We never thought it would circulate so well through our whole place (750 sq ft open loft with 16 ft ceilings), but it has done wonders. We've been running this puppy continuously for over 3 weeks with no problems. It added about $30 to our electric bill, but worth every penny. It switches to fan mode when your desired temp is reached and also has a self-evaporating dehumidifier. The ducting was too short to reach our windows, so we had to buy some, but that's just fine. Our windows tip in, so we had to come up with a little rig to seal the opening around the duct plate (cough-duct tape-cough), but again- that was to be expected for our windows. I can't rave enough about this purchase- Overstock saved our summer!
