High-Efficiency Furnace Options for Littleton Homes

Understanding AFUE Ratings

AFUE (Annual Fuel Utilization Efficiency) measures furnace efficiency:

• 80% AFUE – 80 cents of every dollar spent on gas goes to heating (20% lost through venting)
• 95% AFUE – 95 cents of every dollar goes to heating (only 5% lost)
• 98% AFUE – 98 cents of every dollar utilized for heating (minimal waste)

Efficiency Comparison: Replacing a 60% AFUE furnace with 95% AFUE system saves approximately 37% on heating costs annually.

High-Efficiency Furnace Benefits:
