Heat Pump Payback in New Orleans, LA
Is a heat pump worth it in New Orleans?
New Orleans sits right on the fence, how long you'll own the house decides this one. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. New Orleans's residents would see roughly $297 a year back in running costs, putting the payback around 10.1 years. It's a genuine toss-up here, New Orleans's numbers don't point clearly either way.

New Orleans's weather, in the numbers that matter
Degree days tell the story here: New Orleans racks up 746 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 4030 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 33.1°F here (coldest 2024 reading 26.1°F), which works out to a seasonal COP of 3.19 for the standard class of unit this climate calls for. New Orleans's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Lakefront Airport, the closest NOAA station, 5.7 miles out.
New Orleans's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 592 kWh a year to keep it warm, plus cooling, for a combined electric bill near $545 a year. The gas furnace it replaces burns roughly 8 Mcf a year at $17.38 per Mcf here, for a running cost near $841 a year including the old AC (electricity here runs 13.52¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,448 ahead.
How sensitive New Orleans's result is to prices
In New Orleans the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for New Orleans: the heat pump is worth it within a decade if it costs less than $2,970 more than replacing the furnace and AC, and within 7 years if the gap is under $2,079.
The other scenario: no gas furnace to begin with
Not every home in New Orleans has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
New Orleans against the rest of the country
Ranked against the other 3206 cities covered, New Orleans comes in at 2982 for heating severity, 1 would be the coldest place in the dataset, and 54 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
