Carrier Furnace Secondary Heat Exchanger

This bulletin provides details of the warranty coverage policies and claim process updates.

Carrier furnace secondary heat exchanger.

The chamber becomes corroded from the inside possibly due to a reaction from acidic condensation on the polypropylene coating. The secondary heat exchanger is designed to extract the maximum remaining heat from the fuel source resulting in a normal condensation reaction. High efficiency furnaces also called condensing furnaces have primary and secondary heat exchangers to make more complete use of the heat produced. Our carbon monoxide detector reads 0 when placed adjacent to the furnace while operating.

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.

Condensing furnaces all furnaces include a heat exchanger which converts combustion gases into heat for your home.

The full payment of 270 would go to furnaces 13 years or younger with lower amounts for older units. 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. 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. These carrier secondary heat exchangers do crack and one of the consequences is carbon monoxide leakage.

It states carrier will pay up to 270 to reimburse anyone who previously experienced a failed secondary heat exchanger. 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.
