Cheapest heat pumps to run in Mississippi
Ranked by estimated yearly cost if each model served the same 36,000 BTU/h (3-ton) load in Mississippi, so size doesn't distort the comparison. Because Mississippi's climate weights cooling more heavily, SEER2 (cooling efficiency) matters most here. Choosing the most efficient model over the least efficient one in our database saves about $601 a year for the same load.

Heat pump vs. gas furnace in Mississippi
To heat the same home (900 full-load heating hours at 36,000 BTU/h) in Mississippi, a typical heat pump (HSPF2 9.5) would cost about $492 a year, an efficient one (HSPF2 10) about $468, versus $548 for a 95% gas furnace and $650 for an older 80% furnace, at Mississippi's average residential gas price of $16.65 per thousand cubic feet. In Mississippi, even a typical heat pump beats a high-efficiency gas furnace on heating cost, and an efficient model saves about $80 a year.
Heating only; a heat pump also provides cooling, while a furnace needs a separate air conditioner. Gas prices: EIA, residential, annual average. Compare all states.

Frequently asked questions
How much does it cost to run a heat pump in Mississippi?
Using Mississippi's average residential electricity price of 14.43¢/kWh, a typical 3-ton, median-efficiency heat pump costs about $1,107 a year to run. The most efficient model in our database would cost about $613 for the same load.
Is electricity expensive in Mississippi?
Mississippi's residential rate of 14.43¢/kWh is 21% below the U.S. average of 18.16¢ and ranks #41 most expensive of 51 (EIA, August 2026).
Is heating or cooling the bigger cost in Mississippi?
With our climate assumptions for Mississippi (900 heating and 1,800 cooling hours), heating accounts for about 44% of a typical heat pump's yearly energy use.
Is a heat pump cheaper than gas heat in Mississippi?
For a typical home, heating with an efficient heat pump costs about $468 a year versus $548 with a 95% gas furnace at Mississippi's average prices. In Mississippi, even a typical heat pump beats a high-efficiency gas furnace on heating cost, and an efficient model saves about $80 a year.
