Energy Efficiency (AFUE): 80

AFUE Stands for Annual Fuel Utilization Efficiency. The AFUE number represents how efficiently a furnace converts fuel to energy. The higher the AFUE percentage, the more energy-efficient or fuel-efficient the furnace. The U.S. government’s established minimum AFUE rating for a furnace is 78 percent.

  • 80% AFUE heating efficiency—rating can save you hundreds of dollars each year, compared to older furnaces
  • Improved cooling efficiency—achieved by matching with a Lennox air conditioner or heat pump, the SL280V will improve the system’s SEER**
  • Dual-fuel capability—can be combined with an electric heat pump to create a dual-fuel system. This combination minimizes heating costs by seamlessly alternating between the two energy sources, depending on outdoor conditions.
  • iComfort®-enabled technology—allows the furnace, when installed with the easy-to-use programmable iComfort Wi-Fi® thermostat, to exchange information and make adjustments as needed to optimize performance and efficiency***
  • Sealed blower compartment—minimizes losses and maximizes efficiency and comfort
