Carrier furnace secondary heat exchanger.

These carrier secondary heat exchangers do crack and one of the consequences is carbon monoxide leakage. The full payment of 270 would go to furnaces 13 years or younger with lower amounts for older units. 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. It states carrier will pay up to 270 to reimburse anyone who previously experienced a failed secondary heat exchanger.

The secondary heat exchanger is designed to extract the maximum remaining heat from the fuel source resulting in a normal condensation reaction. The chamber becomes corroded from the inside possibly due to a reaction from acidic condensation on the polypropylene coating. Condensing furnaces all furnaces include a heat exchanger which converts combustion gases into heat for your home. 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.

Most standard models with one heat exchanger deliver around 80 afue efficiency. 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. There is a sliding scale of compensation correlating to the age of the furnace. Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better afue efficiency.

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