  • Description

    Same 80,000 BTU modulating precision — in a wider 21" downflow cabinet for larger cooling systems. The Goodman GDVM970804CN delivers everything the GDVM970804CN offers — 97% AFUE, true modulating gas valve, variable-speed ECM blower, ComfortBridge™, CoolCloud™, and Energy Star certification — in a wider 21" downflow cabinet with a 4-ton blower sized for homes with 2-4 ton R-32 cooling systems. The right choice when your installation requires the larger 21" cabinet footprint in a downflow configuration without sacrificing any of Goodman's most advanced furnace technology.

    Why You'll Love It:

    • 97% AFUE efficiency — converts 97 cents of every energy dollar into heat, the highest efficiency rating available in the entire Goodman downflow furnace lineup
    • 80,000 BTU input / 77,600 BTU output — powerful, consistent heating for medium to large homes without oversizing or wasted capacity
    • Self-calibrating modulating gas valve — infinitely adjusts output between 40% and 100% to precisely maintain your exact set temperature with virtually no swings or cycling
    • True variable-speed ECM blower at 1,600 CFM — 4-ton blower specifically engineered to handle the airflow requirements of up to 4-ton R-32 cooling systems
    • 4-ton blower sizing — the critical difference from the GDVM970804CN, making this the correct downflow pairing for homes with up to 4-ton cooling systems in a 21" cabinet
    • Energy Star certified — independently verified to meet strict energy efficiency guidelines set by the US EPA — may qualify for utility rebates in many states
    • Auto-Comfort mode — automatically optimizes airflow and temperature balance for whole-home comfort without manual adjustments
    • Enhanced dehumidification mode — actively manages indoor humidity levels during cooling season for greater year-round comfort
    • ComfortBridge™ communicating technology — enables smarter system communication between components for optimized whole-home comfort and efficiency
    • CoolCloud™ Bluetooth app — allows contractors to commission, diagnose, and service the unit directly from a smartphone or tablet without removing the cabinet panels
    • Downflow / horizontal installation — purpose-built for closets, alcoves, and attic installs where air needs to travel downward through the duct system
    • Wide 21" cabinet — compatible with 2-4 ton R-32 cooling systems
    • Certified for direct vent (2-pipe) or non-direct vent (1-pipe) — flexible venting configurations for easier installation in a variety of applications
    • Left or right gas and electrical connections — convenient field flexibility for faster, easier installation
    • Heavy-duty aluminized-steel tubular primary heat exchanger — engineered for long-lasting durability and efficient heat transfer with wrinkle-bend technology for added dependability
    • Stainless-steel sloped secondary heat exchanger — the sloped design improves condensate drainage and heat extraction to achieve the industry-leading 97% AFUE efficiency rating
    • Heavy-gauge steel cabinet with less than 2% air leakage — airtight construction minimizes heat loss and reduces sound output for quieter, more economical operation
    • 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 with constant memory and dual 7-segment display — stores fault codes and displays them clearly for fast, accurate troubleshooting
    • Compatible with electronic air cleaners and 120V or 24V humidifiers — wire directly to the low-voltage terminals for seamless indoor air quality integration
    • 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
    • Complies with California Low NOx 40 ng/J emissions standard — approved for installation in all US states including California
    • R-32 compatible — future-ready refrigerant support for pairing with modern R-32 cooling systems
    • AHRI Certified, ETL Listed, and Energy Star Qualified — independently verified for safety, performance, and energy efficiency
    • Made in the USA — designed, engineered, and assembled domestically

    ⚠️ Downflow / Horizontal installation only. For upflow applications, see the GRVM970804CN.

    ⚠️ PVC/Plastic venting required — this is a 97% AFUE condensing furnace and cannot use metal flue venting.

    ⚠️ Not sure which 21" downflow model you need? This unit — the GDVM970804CN — is specifically for homes with 2-4 ton cooling systems.
