I have an old furnace that I am trying to get some info about: Luxaire SH100d, 100,000 btu, 80% eff.,natural gas forced air. No serial numbers on the unit. It looks like someone did some cannibalizing and some parts ended up on the unit.
I am looking for the approximate age, i.e., the year(s) when Luxaire made this particular model. I know about York taking over, etc.
Thanks for any help!
The house was built in the 1940s, but I think the furnace was replaced in the 60s. Just guessing.
