We are using this unit to cool our 500 sq. ft. garage to keep our pets cool during the 112-115 degree heat we are experiencing here in Arizona. I didn't think a unit this small and portable could do the job, but it can. The only setup is making sure you have an exhaust vent so the hot air has someplace to go. The unit is a bit heavy for us old folk to lift, but it is on four wheels so it is easy to move around with ease. Most important is the customer service you get from Newair. If you need help, they are there to assist you all the way. The old-fashioned customer service where they make sure you are completely satisfied. If you're lucky enough to speak with Elizabeth, consider yourself blessed. Now don't you all be asking for her or she'll never be able to get anything done - but that lady deserves a medal. :-)
