Brought mid July when central went out. Hottest months of year & it’s cooling my 1200sq ft home. Unbelievably. Still using at now it’s end of August. Which is our hottest month. Very comfortable in my home. Who would thought. Another great feature it lets you know when to clean filter. Which is something I use to always forget til my other unit would freeze up. Also came with great insulation pieces to place in window. GREAT BUY.
