Carrier Furnace Secondary Heat Exchanger

High efficiency furnaces also called condensing furnaces have primary and secondary heat exchangers to make more complete use of the heat produced.

Carrier furnace secondary heat exchanger.

Carrier provides an enhanced warranty on the secondary or condensing heat exchangers for the above listed 90 high efficiency furnace models within the stated serial number ranges. This bulletin provides details of the warranty coverage policies and claim process updates. Our carbon monoxide detector reads 0 when placed adjacent to the furnace while operating. The chamber becomes corroded from the inside possibly due to a reaction from acidic condensation on the polypropylene coating.

There is a sliding scale of compensation correlating to the age of the furnace. By only replacing the secondary heat exchanger however a homeowner s secondary heat exchanger will be new but the rest of their furnace will still be old. Condensing furnaces all furnaces include a heat exchanger which converts combustion gases into heat for your home.

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. A damaged leaking or cracked unit can allow dangerous carbon monoxide to leak gasses into the airflow and thus spreading the odorless co gas into your home along with the warm air. Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better afue efficiency.

The secondary heat exchanger is designed to extract the maximum remaining heat from the fuel source resulting in a normal condensation reaction. Carrier furnaces eligible for these trade in allowances are covered by an enhanced warranty on the secondary heat exchanger see service managers bulletin smb09 0024.
