HOW TO USE IT
How to use the Heat Pump Replacement Cost Calculator
- 1
Choose the heat pump type (air source, geothermal or mini split).
- 2
Select size in tons and efficiency class.
- 3
Set whether ductwork is new and whether the old system is removed.
- 4
Review the total cost and line-item breakdown.
THE MATH
Heat pump replacement cost formula
Total = unit × size × efficiency + ductwork + removal + labor + permitsA 3-ton air source unit runs ~$7,000, geothermal ~$20,000, mini split ~$5,000. Size and efficiency add 10-50%. New ductwork adds ~$4,000. Labor runs ~$65/hr.
PRACTICAL EXAMPLE
3-ton air source heat pump, high efficiency, existing ducts
Unit = $7,000 × 1.1 × 1.1 = $8,470. Labor = 16 h × $65 = $1,040. Removal = $900. Permits = $500. Total ≈ $10,910.
FAQ
Frequently asked questions
How much does a heat pump replacement cost in 2026?
Use $4,500-$12,000 as an initial installed air-source planning range; geothermal can run much higher.
Do I need new ductwork?
Not if the ducts are in good shape; a new network adds $3,000-$5,000.
What size do I need?
Use a Manual J load calculation; square footage alone is not enough to select capacity.
