Gas Furnace Replacement Costs by City
Fair-price benchmarks for a mid- to high-efficiency gas furnace replacement, like-for-like. Off-season installs (spring or summer) are typically cheaper and easier to schedule.
Efficiency matters: AFUE (Annual Fuel Utilization Efficiency) ratings range from
80% to 98%. A 95%+ high-efficiency furnace costs $500–$1,500 more upfront but can cut heating
bills significantly in cold climates. In mild climates, the payback period may not pencil out —
ask your contractor to run the numbers for your home.
