I guess my furnace is living on borrowed time, it's the original Lenox
installed in the house 59 years ago. I had the blower motor re-built a
couple of times & just general checkups but its still working fine.
Probably not very efficient in comparison to the current new furnaces.
Although I'm looking to replace it & get whole house A/C this year.

Our 14 year old Byrant Plus 90 furnace has been diagnosed with a

The tech suggested that rather than replacing the motor, we consider
purchasing a new furnace, because it has been his experience that the
replacement blower motors have some sort of conflict with the circuit
boards in the furnace. He added that 12 to 15 years of life was typical
for this type of furnace, so a replacement furnace at this time was not
unusual.

If we were to replace the furnace, is there another brand that might
have a longer average lifespan than 12 to 15 years? Or is 12 to 15
years of use typical for all forced air, high efficiency gas furnaces,
regardless of maker?

Sounds like BS to me and that perhaps the so called "tech" might get a
commission on a new unit. Call another independent HVAC guy for
another opinion. I changed the blower motor on our old furnace. Cost
$160+ IIRC and took a couple of hours including the trip to Grainger
to get a new motor. Lasted for years until we changed the furnace when
we converted to gas and got central AC.
