I don't know the efficency of the old unit, and neither does the person I
spoke with at Carrier.
The new unit is 80%.
The old one was made in 1985.

I currently have a 20 year old Carrier Gas Forced Air furnace model
number
58GP125-3 It says the INPUT is 125,100 BTU but the output field on the
label is blank.

An HVAC company wants to replace this with a Carrier model 58STA110. He
says this will result in the same or greater output as my unit. Is he
correct?

Thanks,

Probab;y, yes. Do some math...if your old furnace is 80% effcient the
output is 100,000 BTU. If the replacement is 90% or better you have
99,000+ BTU, close enough for practical purposes. HTH
