Furnace efficiency is measured by AFUE (Annual Fuel Utilization Efficiency):

• Single-Stage Furnaces (80% AFUE):
  • Basic on/off operation.
  • Least efficient but lowest cost.
  • Temperature fluctuations.
• Two-Stage Furnaces (96% AFUE):
  • Two-level operation (high/low).
  • Improved energy efficiency and quieter operation.
  • Reduced temperature swings.
• Modulating Furnaces (98.2% AFUE):
  • Variable output for consistent temperatures.
  • Most energy-efficient and comfortable.
  • Eliminates cold and hot spots.

Choosing Between Repair and Replacement:

• Use the “50% Golden Rule”: If repair costs exceed 50% of the furnace’s value, replacement is recommended.
