Questions2
Is a heat pump worth it in Louisiana?
At Louisiana prices a typical heat pump heats a house for about $314 a year, against $382 for a 95% gas furnace, so it is cheaper to run even before counting that it replaces the air conditioner.
Do I need a cold-climate heat pump in Louisiana?
Generally not. None of the Louisiana cities we track has winters cold enough to require a cold-climate model, although one still helps on the coldest nights.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
