Hello my name is Virgil Heath. I’m new to home inspections I was woundering how David came up with the age of the furnice? What numbers did you go buy? Any help would be GREAT.

I see a lot of questions in this forum related to furnace ages. The best book I ever purchased (7" x 7") is a book published by CarsonDunlap called the Technical Reference Guide. I paid $59.00 for the book at an inspection conference. Just turn to the manufacturers page in the book and you can immediately identify the furnace age. I don’t know for sure, but it seems like the book covers every brand of furnace ever made. A must reference book for your tool bag.

Virgil - the second set of numbers in the serial number in the question posted by Steve is how you know it was manufactured in 2000.
