How Do I determine the tonnage of my A/C unit?
Where on the information plate on a standard exterior residential A/C unit will it tell me the tonnage? Is there a mathmatical equation between the FLA and RLA? Thank you for your professional advice.

LOL sline-dawg. It must be Friday.I added nominal in my original post. The unit may not, and likely doesn't, get precisely that many BTU's (it can vary slightly). Are you planning a replacement, having issues, or just wish to know the tonnage?

He wants to move it, and wants to know how much it weighs.

Yes sir
The model number gives you the tonnage. You will see a number such as 36 42, 48 ,54 etc.Somewhere in the model #. 36=3ton 42=3 1/2 ton so on.

I have an old Sears and Roebuck unit. Can you tell me what the tonnage of my system is?
These numbers are from the evaporator in my attic:
Model: 867.813150
MFR. No.: 64755
Type No.: 55-94753
R22: 29oz
So, there is a "50" in the model number. Does that make it 50,000 BTU for about a 4 Ton unit?
BTW, the outside condenser/compressor eats about 25AMPs on one of the 110Volt legs
Any recommendations on what to replace the condensor outside with (Brand)?
Thanks a TON!

You need to replace both indoor and outdoor unit.
Can't tell you by that model number. But a load calc can tell you what size you need.
