The Goodman GM9S800403AN gas furnace is built with high-quality materials and offers efficient operation at an excellent value. Featuring a single-stage, 9-speed design, it utilizes Goodman's superior heat exchanger for reliable and efficient heating in your home. If you want to reduce energy costs and enhance comfort affordably, the Goodman GM9S800403AN is the ideal choice.

Product Features:

• 40,000 BTU Capacity: The GM9S800403AN Goodman gas furnace delivers 40,000 BTUs (British Thermal Units) of heating power per hour. This represents the furnace's input rate, while the output is 32,000 BTUs per hour (calculated as 40,000 BTUs multiplied by the 80% AFUE). Typically, this 40,000 BTU furnace is employed to heat smaller homes, particularly in ideal climate conditions.

• 80% Efficiency Rating: The GM9S800403AN Goodman gas furnace achieves an 80% efficiency rating, which is the standard efficiency rating in today's furnace market. This means that 80% of the gas consumed by the furnace is utilized for heating your home, while the remaining 20% is expelled through the flue venting. Please note that 80% efficient furnaces require metal flue venting, while those with efficiencies exceeding 90% must use plastic/PVC venting. It's important to mention that this furnace does not comply with California Low NOx or Ultra-Low NOx regulations.

• Single-Stage Furnace: The GM9S800403AN Goodman gas furnace operates as a single-stage furnace, providing a consistent 100% heat output whenever the thermostat demands it. Similar to a light switch, the furnace's burner is either on or off, with no intermediate settings. Single-stage furnaces are considered standard in terms of efficiency, delivering consistent energy consumption with each cycle.

• Natural Gas or LP Furnace: Out of the factory, the GM9S800403AN runs on natural gas. However, all Goodman gas furnaces can be converted to propane using the corresponding LP conversion kit, an optional accessory available at an additional cost. This kit includes a set of replacement orifices and springs.

• 9-Speed ECM Blower Motor: Unlike the previous generation PSC blower motor, the GM9S800403AN employs a multi-speed ECM motor. This motor consumes less power and provides intelligent air circulation, resulting in overall increased electrical efficiency and cost savings.

• Warranty Coverage: When installed in accordance with state and local codes and registered online, all Goodman furnaces, including the GM9S800403AN, come with a 10-year parts warranty and a lifetime heat exchanger warranty from the manufacturer.

• Durable Hot Surface Igniter: The hot surface igniter used in modern Goodman furnaces is more durable than previous designs, reducing related issues and lowering maintenance costs. These igniters are also more efficient compared to standing pilot and older HSI designs, resulting in additional savings.

• Self-Diagnostic Control Board: Goodman has incorporated improved technology into their furnaces, drawing from years of production experience. In the rare event of an issue, the control board utilizes sensors to diagnose basic problems, facilitating troubleshooting and notifying the owner about recommended maintenance or warranty work. This enhances overall safety for both the furnace and the occupants of the home where it is installed.

• Heavy Gauge Steel Cabinet: The heavy-gauge steel cabinet on newer Goodman furnaces provides robust protection for the unit's internal components. The cabinet is also more airtight than previous models, contributing to a quieter and more economical unit by minimizing heat loss and sound transmission.

• Ease of Installation: Modern Goodman furnaces are designed to simplify installation. The GM9S800403AN model, in particular, offers a universal design, allowing installation in both upflow and horizontal (right or left) configurations, accommodating various locations, from attics to basements. Additionally, the furnace comes with color-coded low-voltage terminals, reducing installation time and costs.
