Living in Northern New England the past 20 years, we need AC for about 2-3 months each season. Owning central AC makes no sense.  Therefore, I've gone the window route with great success.  This is my first Energy Star and WiFi connected Smart AC.  I immediately saw a drop in my monthly electric bill.  In the ECO mode it automatically turns on and off once I set the temperature. From my phone I can check the room's temperature and turn on the unit on my way home.  This is the perfect AC!  I own one other window unit and next season it will be replaced by this same model.  As a point of reference, I am able to easily cool 1000 square feet of living space with this model plus my other 5000BTU window unit. Perfect! Perfect! Perfect!
