The Armstrong Furnace R613596-07 Heat Exchanger is an OEM replacement heat exchanger assembly for compatible Armstrong Air forced-air gas furnaces. It is the part that does the work of heating the house. The burners fire into it, the hot combustion gases travel through its tubes or cells, and the blower pushes conditioned air across the outside surface. The metal wall between the two keeps flue gas, including carbon monoxide, completely separate from the supply air stream, which is why a cracked or corroded exchanger is a safety problem and not just a comfort problem.

Part number R613596-07 gives technicians an exact identifier for a furnace replacement part on compatible Armstrong equipment. The trailing -07 is part of the number, and a related heat exchanger is listed under the separate dash number R613596-08, so do not treat the dash numbers as interchangeable. Furnace configurations and component revisions differ by model, capacity and production run, so confirm the complete furnace model number, serial number and the number on the original heat exchanger before ordering. Do not rely on appearance or on BTU input alone.

Typical signs of a failing exchanger include visible cracks or holes, rust and scale inside the cells, flame that changes shape or lifts when the blower starts, soot on the burners, a flue gas odor and carbon monoxide in the supply air. Causes include thermal stress from repeated heating cycles, overfiring, restricted airflow from a dirty filter or blocked air passages, a failed blower and condensation corrosion. Replacement is a job for a qualified HVAC professional following the furnace's service procedures and local codes. Inspect the burners, gaskets and seals, vent and flue connections, combustion air passages, limit switches and mounting points while the unit is open. After installation, verify gas pressure, flame pattern, temperature rise and carbon monoxide levels with a combustion analyzer.

Key Benefits

  • OEM Replacement: genuine Armstrong Furnace R613596-07 heat exchanger assembly for compatible Armstrong Air furnaces.
  • Safe Separation: keeps combustion gases and carbon monoxide out of the supply air while moving heat into the airstream.
  • Exact Identification: part number R613596-07 helps tell this assembly apart from related numbers such as R613596-08 and reduces ordering mistakes.
  • Service Ready: suited to professional furnace repair when cracking or corrosion has been confirmed on the original exchanger.

Common Questions

  • What is the Armstrong R613596-07? It is an OEM heat exchanger assembly for compatible Armstrong Air forced-air furnaces.
  • How do I know the R613596-07 fits my furnace? Verify the full furnace model, serial number and the original heat exchanger part number. R613596-08 is a separate dash number, so match the exact suffix.
  • Who should install a furnace heat exchanger? A qualified HVAC technician. The job involves the combustion and venting system and requires combustion analysis and carbon monoxide testing after the work.
