Reliable efficiency from a solid performer.
Every Trane 80 furnace delivers an AFUE
(Annual Fuel Utilization Efficiency) of up to
80%, exceeding government standards for new
furnace efficiency. That means a full 80% of the
fuel you pay for is converted into heat you can
use. If your current furnace is 15 or more years
old, replacing it with a Trane 80 furnace is a
smart investment not only in your energy use,
but also in your comfort.

Stay warm. Stay smart.
The efficiency of any furnace is measured in AFUE,
or Annual Fuel Utilization Efficiency. AFUE measures
how much of the fuel you pay for is actually turned into
usable heat. Because of their smart design, Trane 80 gas
furnaces have an AFUE of up to 80%,
meaning up to 80% of your fuel is
converted into usable heat. With
that kind of efficiency, you can
keep your home comfortable
while still using energy wisely
