    You might get close if you had a breaker size of the A/C, or the amp draw. Couldnt find that number though for the furnace.

    Maybe take a closer look at the units, most of the model numbers have about twice that many numbers and digits. When I was first asking about mine I was using the first block of numbers and digits, and turned out the second block is what had all the size information.
