Goodman 30,000 BTU 96% AFUE Two-Stage Gas Furnace Upflow/Horizontal 14" Cabinet R-32

The smallest Goodman furnace available — but don't let the size fool you. The Goodman GR9T960303AN packs full two-stage heating and top-tier 96% AFUE efficiency into the most compact furnace in the entire Goodman lineup. At just 30,000 BTU in a slim 14" upflow cabinet, it's purpose-built for small homes, condos, townhomes, and supplemental heating applications where space is extremely limited but efficiency and comfort still matter. No other Goodman furnace fits in a tighter space while delivering this level of performance — period.

Why You'll Love It:

• 96% AFUE efficiency — converts 96 cents of every energy dollar into heat, the highest efficiency rating available in the Goodman furnace lineup — a significant upgrade over 80% and 92% models
• 30,000 BTU input / 28,800 BTU output — the smallest BTU output in the Goodman lineup, perfectly sized for small homes, condos, townhomes, and supplemental heating without oversizing or wasted capacity
• Two-stage gas valve — runs at 60% output on mild days for gentler, quieter cycling and more even room temperatures, then ramps to 100% full power when temperatures really drop
• 9-speed ECM blower motor — precise, whisper-quiet airflow that outperforms older PSC motor units, delivering consistent comfort even in the smallest spaces
• Upflow / horizontal installation — flexible placement in basements, closets, or utility rooms to suit your home's layout
• Ultra-slim 14" cabinet — the smallest and narrowest furnace cabinet in the entire Goodman lineup, compatible with 1-2 ton R-32 cooling systems — fits where no other Goodman furnace can
• 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
• 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
• 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.
