Heat pump cost in Mississippi
It's nearly a tie in Mississippi (within $118 a year). For 2,000 sq ft we estimate $1,133 a year with a minimum-efficiency heat pump versus $1,015 for a gas furnace plus central AC.
Yearly running cost in Mississippi
| Heat pump heat, 7.5 / 9.5 HSPF2 | $766 / $605 |
| Heat pump cooling, 14.3 SEER2 | $367 |
| Furnace, 95% / 80% AFUE | $648 / $770 |
| AC at 14.3 SEER2 (Southeast min) | $367 |
| Heat pump vs furnace + AC | $1,133 vs $1,015 |
The heat pump costs about $118 a year more to run, so it has to win on purchase price, e.g. when the AC is due anyway.
15.19¢/kWh (EIA, July 2026 YTD); gas $1.63/therm (EIA 2025, $16.65/Mcf at 1,023 Btu/ft³). Energy only; estimates.
Installed cost (estimate)
We have no state-level installation data, so these are national estimates: about $10,000–$20,000+ installed for a 2,000 sq ft air-source system. Given Mississippi's mixed climate, start with the 16–17 SEER2 / 8–9 HSPF2 tier, which HomeGuide prices at $8,000–$15,000+.

Climate and sizing
Mississippi averages 2,389 heating degree days (44th of 48) and 2,181 cooling degree days (NOAA, 1991–2020). In practice, both seasons matter, which suits a heat pump that replaces furnace and AC at once. Jan's implied mean, roughly 46°F (degree-day approximation), is within what most modern heat pumps handle with little backup heat.
Heating and cooling loads are comparable; have a Manual J check both, and consider a variable-speed unit.

Questions
How much is a heat pump in Mississippi?
About $10,000–$20,000+ for 2,000 sq ft (national estimate, HomeGuide). Get three local bids.
What electricity price makes a heat pump beat gas in Mississippi?
About 12.8¢/kWh for a 7.5 HSPF2 heat pump against a 95% furnace at $1.63/therm; prices would need to fall about 2.3¢ from Mississippi's 15.19¢ average. A 9.5 HSPF2 unit would heat for $605 a year.
Is there a federal heat pump tax credit in 2026?
Not for 2026 installs. The federal 25C credit (30%, up to $2,000/yr for qualifying heat pumps) covered property placed in service from 2023 through December 31, 2025; 2025 installs also needed the manufacturer's QMID on the return. Source: IRS: Energy Efficient Home Improvement Credit.
