Lennox Heat Exchanger Assembly Aluminum BTU

The Lennox furnace heat exchanger assembly is a genuine OEM replacement part for Lennox gas furnaces. It is also sold as a furnace heat exchanger, primary heat exchanger, or heat exchanger replacement. It is the core component that moves heat from the burner flame into the air circulating through your home. It also keeps combustion byproducts sealed away from the living space.

Key Features:

• Genuine Lennox OEM construction, built to the factory heat transfer surface and airflow path
• Aluminum or aluminized material, as listed for each part number
• Sealed design that isolates combustion gases from the conditioned air stream
• Available in a range of BTU capacities to match different furnace models and series
• Supplied as an assembly for replacement of the original unit

A heat exchanger is a safety-critical component. A genuine Lennox part helps keep the fit, sealing and heat transfer as designed, so the furnace can return to its rated efficiency and reliable operation. Replacement is typically considered when there are cracks, rust or scaling, flame rollout, soot deposits, or repeated limit-switch shutdowns. Installation should be done by a qualified HVAC professional.
