I am currently getting quotes to replace my old/existing 4 ton central ac with a new one. At the moment I am looking at the Trane XB13 Condenser part number: 2TTB3048A and 2TEC Air Handler: 2TEC3F48A1000A.
I am on a very limited budget but I would like to explore the possibility of a 2 stage system. The trane website is a bit confusing to me so I am having a hard time figuring out which condenser, which air handler, and which thermostat would give me the least expensive 2 stage? I would like to have the part numbers for reference when I ask my contractor. Any help is greatly appreciated.
