Where Can I Find The Lennox Model Numbers
from web site
You can find the model and serial numbers (M/N and S/N) for your furnace by removing the top-front service panel and looking to the left side of the interior cabinet or the top of the blower deck, depending on whether your system is an 80% or 90% AFUE unit. Also, the orientation (horizontal or vertical) and flow direction (down or up) of your furnace may impact the location of the information.
Hello Everyone, I have a model number from a lennox HVAC unit, could someone give me a definite on the yr. I am pretty sure Its 1998, but just wanted to run it by you guys. The unit looked 21 yrs old but all my charts say 12.
That looks like the model number. And the only thing that comes close to that number (in Prestons) was manufactured in the mid 60’s. If you can locate the serial number, the first two digits are the plant number; the third and fourth digits are the year. The letter A is for January.
Beginning in 1974 the third and fourth digits of the Lennox Model Number indicate the year followed by a letter indicating the month.
