Jeff Beck Posted March 27, 2009 Report Share Posted March 27, 2009 Need help with the age of a Republic L-125 furnace with a serial number of 5536. Could this actually be the 36th week of 1955? Also, I have never seen an air handler set up like this: Squirrel cage fan with two belt driven motors. Only one motor was actually connected to the fan pulley but both motors kicked on when the furnace called for circulation.

The client was a young HVAC Tech who said he had never seen anything like that. Needless to say neither have I.

I googled Republic Furnace but couldn't find anything on them. Can anyone explain how this works, or more importantly why it was set up this way? Thanks!
