What our Experts Think

• Variable‑Speed Comfort Control
  • The variable‑speed blower motor continuously adjusts airflow to match demand, improving temperature consistency, quieter operation, and better air circulation compared with single‑stage units.

• Two‑Stage Heating Performance
  • With two heating stages, the furnace runs at lower capacity for mild days and full power when it’s cold, reducing cycling and enhancing comfort.

• Good Seasonal Efficiency
  • 80% AFUE provides solid heating performance at an affordable price point — a dependable choice for moderate climates.

• Flexible Installation Options
  • Designed for upflow or horizontal configurations, making it suitable for attic, closet, or crawl‑space setups where space constraints matter.

• Standard 115 V Operation
  • Uses everyday 115‑volt power, simplifying electrical connections during installation.

• R‑32 System Compatibility
  • While the furnace itself doesn’t use refrigerant, pairing it with R‑32 air conditioning equipment supports modern efficiency goals and environmental performance.
