Bryant gas furnace age and efficiency

I recently bought a home and I want to find out the age and efficiency of the furnace (the owner was unsure or didn't want to say). Anyone know where I can find this info? The furnace is at least 15 years old, so their website doesn't have any info on it. The model is

394dac048125 and it is a series FA29. It is a 125K BTU gas furnace. Any ideas on age efficiency? Thanks.

There should be a plate on the furnace somewhere. It will list the input BTU's, as well as the BTUs of heat output.

Do the math, and you have your efficiency.

Tim, that will give you only the firing efficiency, not the AFUE. For years the standard firing efficiency was 80%, while the standard AFUE was between 50% and 60%. The OP should be more interested in the AFUE or Annual Fuel Utilization Efficiency.
