How do I find the size in BTU's of a GE Zoneline air condiitioner or heat pump from the model number?

Wednesday, December 1, 2021

Look for the second set of two numbers between letters in the model number on the data sticker for the size in thousands of BTU’s of a GE Zoneline PTAC air conditioner or heat pump. For example, AZ45E15DAB indicates 15,000 BTU (1.25 tons) and AZ65H09DABW1 is 9,000 BTU (.75 tons).
