How AFUE Works
An 80 AFUE furnace converts 80% of its fuel to heat and wastes roughly 20% up the vent. A higher-AFUE furnace wastes less.
Why It Matters in Chicago
Chicago's long heating season makes efficiency a meaningful factor in operating cost. A technician can explain efficiency options during an installation assessment.
When to Call a Professional
Request a furnace installation assessment to discuss efficiency options for your home.
