The formula
Net cost = (tons x cost per ton x efficiency) + permit − tax credit; Payback = net cost / annual savings
The federal 25C credit covers 30% of qualifying heat pump costs up to $2,000 per year. Savings depend on what you are replacing — the swing is largest when displacing electric resistance heat.

Frequently asked questions
How much does a heat pump cost to install?
Typical 2026 installed pricing is $7,000 to $16,000 before incentives, driven mostly by capacity and whether you choose a cold-climate variable-speed system.
Is there still a heat pump tax credit?
The federal 25C credit covers 30% of qualifying costs up to $2,000 per year for eligible high-efficiency heat pumps. Many states and utilities add rebates on top.
Ducted, ductless or cold-climate: which drives cost most?
System type and efficiency tier move the price more than anything else. A standard 15 SEER2 ducted system is the baseline in this calculator; high-efficiency 17–18 SEER2 units run about 15% more, and cold-climate variable-speed systems about 45% more for the same tonnage. Ductless mini splits are priced per indoor zone instead — use the mini split calculator for those.
How does the tax credit change payback?
The credit is capped at $2,000, so it matters most on mid-priced systems. On the worked example, $9,600 installed drops to about $7,600, cutting simple payback from roughly 10 years to about 8 at a $950 annual saving. On a $16,000 cold-climate system the same $2,000 shortens payback proportionally less.
Why does my state's price differ from this national figure?
This page uses a US national baseline. Labor rates, material pricing and permit fees vary by state, so each state version re-prices the same calculation with that state's cost and permit indexes.
