Hello All,

I've used this site a few times when searching for old AC model number information. However, I've run across a few model numbers that I can't find any information on. In summary, I just need the p/n nomenclature so I can come up with a base cooling capacity for my customer.

The units I'm having trouble with are all Trane units, model number starting with: SACO, SXHC, SWUB

If interested, the full p/n's are:
SACO-0174-A
SXHCC4040B
SXHCC5040B
SWUB-C154-K
SWUB-C104-K
SWUB-B304-K

I can make a couple assumptions, but was hoping for the documentation to confirm my assumptions. Thanks in advance. -JRB
