** I'm moving out of my apartment into a house with built in AC, so I no longer need this unit. This keeps my 600 sq/ft apartment ICE COLD. I've only used it once, during that week long heatwave we had this past July 2022. Just purchased it from Amazon in May (before they ran out of stock). Come by the apartment and I can demo the unit for you to prove it still works like a charm. See details (copied from Amazon): 14,000 BTU (ASHRAE) / 9,500 BTU (SACC) cooling capacity.

Please make sure to measure your existing hose(s) before ordering additional accessories. NOTE: Please note that we do not recommend extending the exhaust hose(s) more than 9 feet long.
