Apply the 50% rule: if repair costs exceed 50% of replacement cost, replace. Also replace if your furnace is 15+ years old, has a cracked heat exchanger (safety risk), or repair frequency is increasing. A new 97% AFUE furnace cuts gas bills significantly compared to older 80% models. We give honest repair vs replace advice—no pressure, just facts.

AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts gas to heat. 97% AFUE means 97% of gas becomes heat, only 3% is lost. Older 80% furnaces waste 20% of gas. Higher AFUE means lower gas bills and qualifies for rebates. In London's cold winters, the difference between 80% and 97% AFUE can save hundreds of dollars annually.

Yes. Furnace replacement requires a permit and TSSA inspection. Hawana includes permits and coordinates the inspection in all our installations. This ensures your installation meets safety codes and protects your home insurance coverage. Never hire an unlicensed contractor—it can void warranties, create safety risks, and cause insurance issues if something goes wrong.
