Cheapest heat pumps to run in Louisiana
Ranked by estimated yearly cost if each model served the same 36,000 BTU/h (3-ton) load in Louisiana, so size doesn't distort the comparison. Because Louisiana'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 $517 a year for the same load.

Heat pump vs. gas furnace in Louisiana
To heat the same home (700 full-load heating hours at 36,000 BTU/h) in Louisiana, a typical heat pump (HSPF2 9.5) would cost about $341 a year, an efficient one (HSPF2 10) about $324, versus $445 for a 95% gas furnace and $528 for an older 80% furnace, at Louisiana's average residential gas price of $17.39 per thousand cubic feet. In Louisiana, even a typical heat pump beats a high-efficiency gas furnace on heating cost, and an efficient model saves about $121 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 Louisiana?
Using Louisiana's average residential electricity price of 12.87¢/kWh, a typical 3-ton, median-efficiency heat pump costs about $951 a year to run. The most efficient model in our database would cost about $508 for the same load.
Is electricity expensive in Louisiana?
Louisiana's residential rate of 12.87¢/kWh is 29% below the U.S. average of 18.16¢ and ranks #50 most expensive of 51 (EIA, August 2026).
Is heating or cooling the bigger cost in Louisiana?
With our climate assumptions for Louisiana (700 heating and 2,000 cooling hours), heating accounts for about 36% of a typical heat pump's yearly energy use.
Is a heat pump cheaper than gas heat in Louisiana?
For a typical home, heating with an efficient heat pump costs about $324 a year versus $445 with a 95% gas furnace at Louisiana's average prices. In Louisiana, even a typical heat pump beats a high-efficiency gas furnace on heating cost, and an efficient model saves about $121 a year.
