I have a Carrier Weather maker SX - model number 58SXA100-JG Serial
Number - 4390A02724 - the only reason I'm including the serial number
is because someone told me that you may be able to tell the age of the
unit. I don't know the age of the unit. It is definitely before the
age of blinking leds to help diagnose problems. We had to replace the
AC unit when we moved in 3 years ago, I've replaced it with a Lennox
AC unit.


I'm not too familiar with this model, but I can tell you that it was made
the 43rd week of 1990.

I'm not a big fan of Carrier, but I think they are better than Lennox......
