Why the numbers differ
Each guide uses its own method. Some base their estimates on other sites, such as Angi and HomeAdvisor, and say so on their pages. Two guides can quote different numbers for the same job, so we show them side by side instead of one average.
Questions
How long does a furnace last?
No single number fits every furnace. ENERGY STAR advises considering replacement once a furnace or boiler is more than 15 years old, sooner if it needs frequent repairs while energy bills climb.

What does the efficiency rating on a furnace mean?
The rating is AFUE, the share of the fuel's heat that becomes heat for your home instead of being lost. ENERGY STAR gas furnaces must rate at least 95% in the South and 97% in the North.

When should I replace my furnace instead of repairing it?
ENERGY STAR points to a furnace over 15 years old, or equipment that needs frequent repairs while energy bills go up. Ask your contractor to compare the safety and cost-effectiveness of repair versus replacement.

Why does proper furnace sizing and installation matter?
Oversized equipment may switch on and off too often, which reduces comfort and can shorten its life. ENERGY STAR recommends the contractor size equipment from your home's actual characteristics, not a rule of thumb.
