I live in northern Michigan in an 800 sq. ft. cabin on a small lake. Michigan summers here can be pretty brutal when it comes to heat and humidity and down right uncomfortable. I installed my LG LT1216CER Air conditioner in a new LG AXSVA1 26 In. Wall Sleeve for Through-the-Wall Air Conditioners and I have been comfortable since. The installation was pretty simple and the entire cabin stays cool and dry.
