Overview
California's tough Low NOx emissions standard is a high mark for a gas furnace to meet, but the Goodman GCSS96 manages it easily. This high efficiency unit is built for long term operation, component durability, and, of course, eco-safe cold weather heating. It features a heavy duty tubular heat exchanger made of aluminized-steel, a stainless steel secondary heat exchanger, self diagnostics, silicon nitride igniter, low voltage terminals, and more.
Do you need a budget-friendly, high-efficiency furnace for your home? The Goodman GCSS96 single-stage furnace is what you’re looking for! Engineered for long-term performance and quiet functionality, you’ll be worry-free with the knowledge that your furnace is working hard to create an ultra-cozy and comfortable environment in your home. With an AFUE rating of up to 96%, up to .96 cents of every single one of your valuable dollars goes toward heating your home.
This 40,000 BTU, single-stage gas furnace is ideal for colder climates. Its high durability and efficiency allow the unit to run at full capacity no matter the outside temperature, which translates to maximum heat output for you! The downflow/horizontal functionality makes this unit ideal for closet, attic, or crawl space installation - aesthetic functionality at its best!
Expertly engineered technology delivers a high-value furnace that performs. A strong aluminized-steel heat exchanger paired with a secondary exchanger made of stainless-steel results in dependability, power, and efficiency. And with its quiet multi-speed motor, you’ll delight in owning a system that starts and shuts down without the excess noise common to some other furnaces.
Other beneficial features of this unit include a silicon nitride igniter that eliminates the need for an uneconomical pilot light, a single-speed, induced-draft blower, and a self-diagnostic control board that constantly checks the system for healthy performance. Recent diagnostic codes are stored in the system memory making troubleshooting and HVAC repair a breeze. Lastly, a thermally insulated cabinet reduces sound and minimizes air leakage to less than 2%, boosting heat transfer efficiency.
The Goodman GCSS96 is budget-friendly, durable, and hard-working, making this furnace an all-around winner for your home heating needs!
