3.5 tons
That is a 3 1/2 ton unit. one ton of A/C = 12000 btu. The 42 in the model number refers to 42000 btu.
since the model number has 42, i would say it probably is a 3 1/2 ton.
Most manufacturers put a number related to Btu's of the unit in the model. If Rheem is no different then that 42 represents a 3.5 ton unit as there are 12,000 btu's / ton and 3.5 X 12 = 42.
The 36 indicates it is a 3 ton unit. 12 would be a 1 ton, 24 is a 2 ton, 36 is a 3 ton, 48 is a 4 ton, and 60 is a 5 ton. There are also half ton sizes available, so if those digits were 30 it would be a 2.5 ton, 42 would be a 3.5 ton, etc.

Should be the last 2 numbers in the model number followed by letters. Here's what to look for... 18=1.5 ton 24=2 ton 30=2.5 ton 36=3 ton 42=3.5 ton 48=4 ton 54=4.5 ton 60=5 ton Every 12,000 BTU equal 1 ton. Hope this helps.
