How do you find out what type of system and size the air conditioner is by the information on the label?

I don't understand what you mean by "type of system".
In regard to the part of the question pertaining to size; it is a 24,000 BTU or 2 ton unit.

Can you explain how you got the 24,000 btu/2ton ? Thanks

Last 2 digits of the model number. Judging from the "10" in the model number I would presume this to be a 10 SEER model, but that's a guess.

There are 12,000 BTUS in 1 ton so a serial # ending in 24 usually indicates a 2 ton. You have an older freon 22 system
