hello,
I have the following units
heritage 12 American standard Tyler, Texas mod 6h2036a100a4 ser R302tgc1f
Trane mod bwd718a100b0 ser y47254842
how do break down what the units are in terms of tonnage and information, I have been all over the web and cannot find a cross reference of what the mod and serial numbers on a A/C unit represent. if this is the wrong group, any information where to post would be appreciated. thanks
