Need help from a someone with a Preston's Guide

Could someone tell me the age range for a Solar Aire furnace, model number LG125?


Preston’s does have Solar Air listed. It has “Solitaire” listed but no “LG” #'s:neutral:

LG125 is a Laars number, if that helps. You might try pulling up a picture of the Teledyne-Laars stuff and see if your SolarAire unit seems to be a rebranded Laars.

Hi Russel,

Prestons shows that model as being an Oneida Royal model from between 1965 and 1976, see screen print below



I have a little more information. The inside of the furnace says “North Manufacturing Corp Portland.”
