Heat pump cost calculator
How big of a heat pump does my house need?
For most US homes, heat pump size lands between 2 and 5 tons. The ElectrifyAtlas calculator takes your square footage, climate zone, insulation level, and current heating fuel, applies a Manual J approximation, and returns a recommended tonnage plus estimated install cost. Final sizing requires a licensed HVAC contractor.
How is heat pump size calculated?
Manual J approximation: square footage × BTU load per sq ft (based on climate zone and insulation) divided by 12,000 BTU per ton, then rounded up to the nearest half-ton. For precise sizing, a licensed HVAC contractor performs a room-by-room blower-door test.
How much does heat pump installation cost?
All-in installation ranges $8,000 to $24,000 in 2026. Cost scales with system size (tons), tier (value/standard/premium), and local labor rates. ElectrifyAtlas estimates a low/mid/high range from your inputs and subtracts the stacked rebates you qualify for.
What heating fuel has the highest heat pump savings?
Electric resistance heating has the highest replacement savings — typically 60-70% annual energy reduction. Oil and propane are next. Gas has the smallest savings delta but still pays off in states with utility incentives and low electricity rates.
