What South Dakota Residents Should Know
South Dakota falls in IECC climate zone 5-6A with 7,300 heating degree days per year — well above the national average. South Dakota's cold winters mean heat pump COP averages 2 during the heating season. While this is lower than milder states, modern cold-climate heat pumps with inverter compressors can still deliver meaningful savings over traditional heating systems, especially when paired with a backup for the coldest days.
With natural gas at $0.90 per therm in South Dakota, a gas furnace may have lower operating costs in the coldest months. However, heat pumps provide both heating and cooling in one system, which can offset the difference when you factor in AC savings. In shoulder seasons (spring and fall), a heat pump is significantly more efficient, often making the overall annual cost competitive with gas.
A heat pump also replaces your air conditioner, and South Dakota's 700 cooling degree days make that dual-function value real: one system handles both seasons, so you retire a separate AC unit and its maintenance along with the furnace. For homes with an aging furnace-and-AC pair, replacing both at once is usually where a heat pump makes the strongest financial case in South Dakota.
South Dakota does not currently offer dedicated state-level heat pump incentives, and the federal 25C credit ended December 31, 2025. The case for a heat pump now rests on operating savings and the dual heating-cooling functionality — which, in the right climate and at the right fuel prices, can still make it the better long-term investment. Some utilities also offer their own rebates, so check locally. Enter your home details above to see your projected savings.

Incentives in South Dakota
Federal clean energy tax credits ended in late 2025 under legislation passed in July 2025; they are shown below for reference since recent purchasers may still claim them. State programs are governed separately and many remain active — always verify current details with the program before purchasing.
| Incentive | Type | Amount | Description |
|---|---|---|---|
| Energy Efficient Home Improvement Credit (Heat Pump - 25C)Ended | tax credit | 30% | Federal tax credit of 30% up to $2,000 for qualifying heat pumps. Ended December 31, 2025 — systems placed in service after that date do not qualify. State and utility heat pump rebates remain available in many states. |
Heat Pump Savings in South Dakota: Frequently Asked Questions
- Are heat pumps worth it in South Dakota?
- In South Dakota, low natural-gas prices mean a heat pump may not beat a gas furnace on heating cost alone, but its combined heating-and-cooling in one system, plus efficiency in mild months, can still make it the better long-term choice.
- Do heat pumps work in South Dakota's climate?
- South Dakota sits in IECC climate zone 5-6A with about 7,300 heating degree days per year. Modern heat pumps there average a heating COP of 2, meaning they deliver 2 units of heat per unit of electricity.
- Are there heat pump rebates in South Dakota?
- South Dakota does not currently offer dedicated statewide heat pump rebates, and the federal 25C credit ended December 31, 2025. Many local utilities still offer their own rebates, so check with yours before buying.
