Heat Pump Payback in Natchitoches, LA
Heat pump vs. gas furnace in Natchitoches, LA
In Natchitoches, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $285 saved annually, for a payback of roughly 19.3 years. That's a technicality, not a recommendation, for anyone actually living in Natchitoches.

How cold Natchitoches actually gets
1687 heating degree days pile up here every year, so Natchitoches has a mild winter by US standards; the cooling side runs to 2643 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 21.9°F, and the coldest daily reading in the 2024 station record was 10.9°F. That puts the seasonal coefficient of performance at 3.23 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 21.9°F design temperature Natchitoches falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe.

The yearly running costs in Natchitoches
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,323 kWh a year to keep it warm, plus cooling, for a combined electric bill near $483 a year. That compares with roughly 18 Mcf a year of gas at Natchitoches's $17.38 per-Mcf rate, about $768 a year with the old AC included, against a local electricity rate of 13.52¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,225 behind.
What would change Natchitoches's answer
Gas would only overtake the heat pump in Natchitoches if electricity rose past 202.6¢/kWh from 13.52¢, or gas fell under $1.16 per Mcf from $17.38. A useful quote test for Natchitoches: the heat pump is worth it within a decade if it costs less than $2,850 more than replacing the furnace and AC, and within 7 years if the gap is under $1,995.
The other scenario: no gas furnace to begin with
Not every home in Natchitoches has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Natchitoches against the rest of the country
Natchitoches lands at position 2589 out of 3206 cities on heating severity (coldest is 1), and 2181 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
What to do with this number in Natchitoches
Natchitoches, Louisiana is home to about 17,165 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Natchitoches, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
The methodology guide walks through exactly how Natchitoches's 3.23 seasonal COP and the rest of this page's numbers get built. Natchitoches's 21.9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
