Is a Heat Pump Worth It in South Dakota?
Last updated June 27, 2026 · based on South Dakota energy prices
In South Dakota, where residential electricity averages about 12.5¢/kWh and natural gas about $1/therm, a heat pump may actually cost a bit more to run than cheap natural gas here — the case is strongest if you're also replacing an aging AC. South Dakota has a very cold heating climate, which means a heat pump runs at a seasonal efficiency (COP) near 2.3 here.
South Dakota heating cost comparison (average 2,000 sq ft home)
| System | Estimated annual heating cost |
|---|---|
| Gas furnace (95% AFUE) | $1,000 |
| Heating oil | $3,618 |
| Heat pump | $1,513 |
If you currently heat with oil, the picture is much stronger: a heat pump could save around $2,105/year versus heating oil at South Dakota prices. Against electric baseboard heat, a heat pump cuts heating energy use by about two-thirds, so the savings are even larger.
What this means for South Dakota homeowners in 2026
The federal heat pump tax credit expired December 31, 2025, so a 2026 install in South Dakota carries the full upfront cost unless you qualify for a state or utility rebate. Because South Dakota's climate is very cold, the strongest financial case is when you're replacing both an old furnace and an aging air conditioner at once — the heat pump does both jobs with one system. Since cheap gas keeps running-cost savings modest here, lean on the combined heating-plus-cooling replacement and any available rebates to justify the switch.
South Dakota rebates
Check whether South Dakota has launched its HEEHRA home-electrification rebate program (worth up to $8,000 for income-qualified households) and confirm it still has funding before counting on it — availability changes month to month. Also check your local electric utility, which may offer its own heat pump rebate of a few hundred to a couple thousand dollars. See our 2026 rebate guide for details.
