HEAT EXCHANGER

A heat exchanger is a heating component inside furnaces that transfers heat to the surrounding air, which is then distributed throughout the home.

Lennox® furnaces are engineered with one of two types of heat exchangers:

Duralok Plus™ heat exchanger, built for Lennox’ high-efficiency (90%) condensing gas furnaces, that’s made of high-quality, patented ArmorTuf™ steel to ensure high reliability and efficiency.

  • Duralok Plus is a clamshell heat exchanger and condenser coil assembly

Duralok™ heat exchanger, built for Lennox’ mid-efficiency (80%) gas furnaces, that’s made of high-quality, patented ArmorTuf™ steel to ensure high reliability and efficiency.

  • Duralok is only the clamshell heat exchanger
