We have been told to get a Rheem by my friend's bf who is licensed for AC. He took a 2 yr course for AC. Does anyone know if this is a great brand or not? My house is 1450 sq ft and he is quoting me for a 3-ton and new handler. My attic is tight for the handler which is limiting our options. I just want to make sure I do this right before shelling out so much money! Any help is greatly appreciated!
