Heat Pump vs Furnace Operating Cost Calculator

• Mild to moderate climates (winter lows > 20°F)
• Low electricity rates (<$0.12/kWh)
• High gas rates (>$1.50/therm)
• You need both heating and cooling
• No natural gas available

• Cold climates (frequent temps < 20°F)
• Low natural gas rates (<$1.00/therm)
• High electricity rates (>$0.16/kWh)
• Already have AC, just need heating

Dual-fuel systems use heat pump in mild weather, switch to gas furnace in extreme cold. Best of both worlds but higher upfront cost.
