The 80% furnaces have a circuit board, inducer motor to clear gasses, electronic igniter, flame roll out switch, limit switch and electronic gas valve which makes them electronically the same as a 90% efficient furnace.
I have installed Carrier or the off brand Payne since 1990 and really like their products. My 20 year old no name Carrier made heat pump is still kicking.

Our old furnace was a carrier. Installers said it was a cheap unit but sure served us well. With our mild climate the higher efficiency furnaces would take us 10+ years to pay for themselves - at least with the quotes we got.
