My ac home units is 18 years old and the ac coil is leaking feon. I going to replace my unit with a new one. I presently have a Rheen unit, 2 ton (high efficient) that heats and cool the up steps, which is about 1130 sq. ft. I live in Augusta Ga. What ac unit should I purchase to replace my Rheem and the required seers.
Thanks,
