I am looking at a job where I will be doing a changeout of the furnace only. The job is a split system w/ Trane condenser. I want to know If anyone can tell me the size of condenser by these # TTD730B100A1. I sell Rheem so I'm not familiar with Tranes numbers. this is an older unit but it still works fine so I'm not going to change it out. I already did my heat loss calc. but I want to make sure I provide enough CFM's for the a/c. The existing furnace is grossly oversized and I am hoping the condenser isn't because I want to put the proper size furnace in , but leave the existing cooling if possible. So any help regarding the size of condenser would be appreciated.
