The good news is that most furnace manufacturers offer an extended parts warranty for a heat exchanger that lasts anywhere from 10 years to a limited lifetime warranty.
Carrier furnace heat exchanger.
Most standard models with one heat exchanger deliver around 80 afue efficiency.
The carrier high efficiency gas furnace trade in allowance program is designed to offer homeowners an alternative to replacing only the heat exchanger under the terms of their limited lifetime heat exchanger warranty on a first generation carrier condensing furnace if their furnace experiences a heat exchanger failure.
All furnaces include a heat exchanger which converts combustion gases into heat for your home.
Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better afue efficiency.

Two types of furnace warranties come into play here.
The shape of the coils depends on the type or model of your furnace.
The bad news is that the parts warranty only covers the cost of the actual heat exchanger not the labor required to replace it.
A gas furnace s heat exchanger is the furnace component that actually heats the air.
