I bought this unit in August of 2016. I live in a 900 sq. ft. house and my central AC unit quit. No AC in August in Texas is not good. The AC guy couldn't get here for 5 days and no idea how long to get parts. I cranked the thermostat all the way down. It made the house tolerable until my central unit was fixed. This little unit has energy saver, remote control, digital readout, easy clean filter and did better than expected.
