If you want the best efficiency available in a single-stage downflow furnace at this BTU range, your search ends here.

Why You'll Love It:

• 96% AFUE efficiency — converts 96 cents of every energy dollar into heat, one of the highest efficiency ratings available for a single-stage gas furnace
• 60,000 BTU input / 57,600 BTU output — ideal heating output for small to medium homes without oversizing or wasted capacity
• 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
• Downflow / horizontal installation — purpose-built for closets, alcoves, and attic installs where air needs to travel downward through the duct system
• 17.5" cabinet width — compatible with 1-3 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
• Stainless steel secondary heat exchanger — extracts additional heat from exhaust gases to achieve the 96% AFUE efficiency rating
• Onboard R-32 detection sensor (RDS) — built-in refrigerant leak detection for safe, code-compliant R-32 system pairing
• Silicon nitride igniter — more durable than older hot surface igniters, reducing maintenance calls and replacement costs
• 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
• 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
