You can also look at the inside(evaporator coil) as it should be the same rating as the compressor in the outside(condensing unit) unit. If you are still unable to get the information look on the top of the compressor in the outside unit. The model number and manufacturers name will usually on the top of the compressor. You should then be able to call any HVAC company and they can tell you the BTU rating of the system. Anytime you need info about a similar system you need the brand, model number and serial number. If you get this information I can tell you what you have. If you know the square footage of your residence it is also easy to make a very close guess at the "tonnage" of the system. 12,000 BTU's equal 1 ton, so 18,000 BTU's equal 1 1/2 tons. The BTU rating of a compressor, however, does not tell you the exact rating of the system because of differences in efficiency ratings of the manufacturer. Let me know if I can help further.
look at the inside unit or look at the actual compressor outside. 12,18,24,30,36 are the numbers to look for then divide by 12 and that will give you the TON. 12000 btus=1 ton
The label might be gone, but there's a metal stamp on the door where the fuses go.(Or by the motor)
