The bad news is that the parts warranty only covers the cost of the actual heat exchanger not the labor required to replace it.
Two types of furnace warranties come into play here.
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.
It s comprised of a set of tubes or coils that repeatedly loops through the airflow inside the furnace to heat the air.
Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better 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.
Most standard models with one heat exchanger deliver around 80 afue efficiency.
