My brother just bought a house with a York flat coil model# M2UF032AA in it, the numbers on the cond unit are worn and cant be read, but the compressor name tag and this coil # lead me to believe it is a 2.5 ton unit, he needs a new cond unit and would to go with a 3 ton unit, my question is can change the orifice on this coil and get 3 tons out of it?
