Tony, we don't sell Lennox, but do service a few. Just guessing, but I
would imagine that the "13" in the model numbers means 13 SEER, and the
"42" in the first unit means 42000 BTU or 3 1/2 ton, and the "37" is
37000, or a strong 3 ton. That would be logical-- but then you are
talking about Lennox, so who knows. Hopefully, if I am wrong. someone
will jump in with the correct info. Good luck Larry
Mighta been one was a much older recip compressor. More
amps, well, they were less efficient. They usually mix the
BTU/h into the model numbe. Some brands do.
Nawlins had a hurricane some years ago. Has it come back to
Tony, regarding the rated amperages-- I've seen things like that before.
I remember on Rheem/Ruud years ago I think the 3 and/or 3 1/2 ton 10
SEER units were rated about 1.5-2 amps less than the 12 SEER of the same
size. I think I have seen other units rated similarly to yours where a
unit was rated slightly lower than the one that was one size smaller. On
yours, you are only talking about 1/2 ton difference. You are talking
about the nameplate rating, and not the actual amp draw, aren't you? Is
so, I wouldn't worry about it. Larry
