Airtemp Furnace Age

Model #4365v (could be 4365)
s/n# 6823 032

The above are mod# and s/n# for an old Airtemp Furnace.

Can anyone tell me how old this is?

If I’m not mistaken didn’t they quit making Chrysler AirTemp somewhere around late 70’s or early 80’s. If so lets assume the unit is 30+ yrs old and wewll past its safe economic life-cycle. And we’ll word our report accordingly
