• Heat Exchanger Assy 75K

Bard S171-293 is an OEM 75,000 BTU heat exchanger assembly used in select Bard wall-mounted HVAC heating sections to transfer heat safely and efficiently from the burner side into the supply air stream. Replacing a worn or damaged heat exchanger helps restore proper heat output, maintain designed airflow temperatures, and support safe operation of the unit. Because heat exchanger designs can vary by model and serial range even at the same BTU rating, confirm compatibility with your Bard unit data tag and service literature before ordering Bard S171-293.
