GAS FURNACE
COMPONENT UPGRADE OFFERS
BETTER PERFORMANCE
The aluminized steel, tubular primary
heat exchanger featured in Goodman
brand gas furnaces is likely the most
essential component in a gas furnace’s
performance. This distinctive heat
exchanger employs wrinkle-bend
technology which was developed to
deliver extraordinary durability and
long-term reliability.
The art of precision
Distinctive, Heavy-Duty Heat Exchanger Technology – Constructed from tubular
aluminized-steel, the primary heat exchanger is designed for outstanding durability
and heat transfer. The use of wrinkle bend technology maintains the wall strength of the
tubular design and aids in the efficient transfer of heat.
Two-Stage Gas Valve – Automatically adjusts to the most efficient amount of gas needed
to reach and maintain the temperature selected on the thermostat.
Goodman gas furnaces simply work the way they’re supposed to,
making each one a thing of beauty.
Energy-Efficient Multi-Speed Blower Motor – Provides airflow to match comfort needs,
reduces energy consumption and system noise compared to a single-speed motor.
Durable Silicon Nitride Igniter – This energy-saving technology eliminates the need
for a traditional pilot light. The igniter is constructed for both strength and outstanding
reliability.
Quiet, Single-Speed Induced-Draft Blower – Provides precise control and enhanced
energy-efficient performance as compared to a natural draft furnace.
Self-Diagnostic Control Board – Silently and consistently monitors the gas furnace to
ensure all furnace components are working properly and helps to achieve the energy-
efficient performance too. Also, allows for quick troubleshooting when gas furnace
needs maintenance.
Insulated Furnace Cabinet – Even the metal walls of this gas furnace support energy-
efficiency. A fully insulated cabinet helps to keep the heat inside the furnace and has less
than a 2% air leakage rate. The insulation also assists with noise suppression when the
furnace is operating.
When your current furnace breaks, it’s
good to know that your local, independent
Goodman

options available to help defray what
might be considered an emergency
purchase for your home.
