Goodman 100K BTU 96 Percent AFUE Two Stage Variable Speed Upflow 21 Inch Cabinet

Serious heating power meets Goodman's highest technology — 100,000 BTU of variable speed, two-stage heating at 96% AFUE in a wide 21" upflow cabinet. The Goodman GRVT961005CN is built for large homes with 2-5 ton R-32 cooling systems that demand maximum heating output and maximum efficiency from Goodman's most advanced furnace platform. Every feature Goodman offers — variable speed, two-stage, ComfortBridge™, CoolCloud™, Auto-Comfort, and enhanced dehumidification — all in one unit.

Why You'll Love It:

• 96% AFUE efficiency — converts 96 cents of every energy dollar into heat, the highest efficiency rating in the entire Goodman furnace lineup — a significant upgrade over 80% and 92% models
• 100,000 BTU input / 96,000 BTU output — serious heating power for large homes paired with 2-5 ton cooling systems without oversizing or wasted capacity
• True variable-speed ECM blower at 2,000 CFM — continuously and intelligently adjusts airflow to match exact heating and cooling demand for maximum comfort, minimum noise, and lower electricity costs
• Two-stage gas valve — runs at lower output on mild days for gentler, quieter cycling and more even room temperatures, then ramps to full power when temperatures really drop
• 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
• Upflow / horizontal installation — flexible placement in basements, closets, or utility rooms to suit your home's layout
• Wide 21" cabinet — compatible with 2-5 ton R-32 cooling systems.
• 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 secondary heat exchanger — extracts additional heat from exhaust gases to achieve the industry-leading 96% 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 — stores the last fault codes so your technician can diagnose issues fast, cutting service time and costs
• Compatible with electronic air cleaners and humidifiers — wire directly to the low-voltage terminals on the control board 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
• Low NOx emissions — meets air quality requirements for nationwide installation
• R-32 compatible — future-ready refrigerant support for pairing with modern R-32 cooling systems
• 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 96% AFUE condensing furnace and cannot use metal flue venting.
