Maratherm AC tonnage and age

Trying to determine tonnage on a Maratherm ac unit. Model number R2A33OGKRI.

Not in my Prestons Guide, but I would say 2.5 from the model number.

Yeah, im thinking that too. The number 330 lead to 2.5 or 2.75. But I dont know if its a zero or an “o”. It was not a “easy-to-read” plate.


2-1/2 ton no such thing as a 2-3/4 ton in residential
