The air handler does not have a tonnage rating, the evaporator coil within it is what you`re looking for since any given air handler can accomodate several different coil sizes. For the answer to your tonnage question see the tag on the coil, though that may prove to be difficult since it is enclosed in the plenum. An easier method would be to get the tonnage from the condenser model # in the yard.

While i do not know the answer to your question, i can say if you have a chrysler air handler it is definitely advised to get it replaced. They stopped being made around 40 years ago, and parts are no longer sold for them from the manufacturer.
The 48 in the serial number denotes the tonnage. Divide that number by 12 to get the tonnage of 4.
