I currently have the following old (27 years) GE units installed in my 4800 Sq Ft home. It's a split unit that services all 4800 sq. ft. here are the GE model numbers if someone has the capability to research these and tell me what the specs are I would sure appreciate it.

GE Air Handler Model # BWE960C100C2
GE Condenser Model # BWR960A100A1

I am in the process of replacing but have had conflicting information from installers trying to decide on what I am currently running.
