Heat pump vs. gas furnace in Natchitoches, LA
In Natchitoches, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $285 saved annually, for a payback of roughly 12.3 years. It's a genuine toss-up here — Natchitoches's numbers don't point clearly either way.
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, against a record low of 10.9°F. That puts the seasonal coefficient of performance at 3.23 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Natchitoches sits firmly in cold-climate territory, so that's the class of unit priced here.

The month-to-month numbers for 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 — against a local electricity rate of 13.52¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 47.4 years, leaving the 15-year total $775 ahead.
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. Switching saves about $557 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 14.4 years.
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.
