  • High-efficiency heating built for large homes — without the high-efficiency price tag of a 96% unit. The Goodman GR9S921004CN delivers a powerful 100,000 BTU of single-stage heating at 92% AFUE in a wide 21" upflow cabinet — the smart choice for large homes that need serious heating output with excellent efficiency and long-term reliability. Built and assembled in the USA, backed by one of the best warranties in the industry, and priced to deliver real value from day one.

    Why You'll Love It:

    • 92% AFUE efficiency — converts 92 cents of every energy dollar into heat, significantly reducing operating costs compared to older 80% units
    • 100,000 BTU input / 92,000 BTU output — serious heating power built for large homes, not undersized for the job
    • Single-stage operation with 9-speed ECM blower — steady, even airflow throughout your home with quieter operation and better humidity control than older PSC motor units
    • Upflow / horizontal installation — flexible placement in basements, closets, or utility rooms to suit your home's layout
    • Wide 21" cabinet — compatible with 2-4 ton R-32 cooling systems for a complete, balanced home comfort setup
    • Heavy-duty aluminized-steel tubular primary heat exchanger — engineered for long-lasting durability and efficient heat transfer using wrinkle-bend technology
    • Stainless steel secondary heat exchanger — extracts additional heat from exhaust gases to achieve the 92% AFUE rating
    • Silicon nitride igniter — more durable than older hot surface igniters, reducing maintenance calls and replacement costs over the life of the unit
    • Self-diagnosing control board — acts like a "check engine light" for your furnace, pinpointing issues fast and cutting service time and costs
    • Color-coded low-voltage terminals — simplifies wiring during installation, reducing labor time and costs
    • LP convertible — easily field-converted to propane with optional kit, giving you fuel flexibility for your home
    • PVC/plastic venting required — high-efficiency condensing operation requires plastic vent pipe, not metal
    • Meets Clean Air Act refrigerant requirements — R-32 compatible for pairing with modern eco-friendly cooling systems
    • Low NOx emissions — meets air quality requirements for nationwide installation
    • AHRI Certified and ETL Listed — independently verified for safety and performance
    • Made in the USA — designed, engineered, and assembled domestically

    ⚠️ PVC/Plastic venting required — this is a 92% AFUE condensing furnace and cannot use metal flue venting.
