I am in the process of choosing a replacement PTAC unit for my old (horrible) McQuay PTAC. Area is about 650sqft (a large studio 2 blocks from the beach). It gets very hot during the day when it will be mostly used. Any suggestions on best brand and btu? I was looking at Trane, GE Zoneline 5500, and Carrier ---- all look the same to me. Any experience with these guys? It gets very hot so I am looking for something that will make my unit very cold - best performance and reliability.
Thanks for your help!
