Heat Pump Payback in Pascagoula, MS
Should Pascagoula switch to a heat pump?
This one's marginal in Pascagoula: it only clears if you stay long enough. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. Pascagoula's residents would see roughly $277 a year back in running costs, putting the payback around 10.8 years. It's a genuine toss-up here, Pascagoula's numbers don't point clearly either way.

Pascagoula's weather, in the numbers that matter
Pascagoula barely has a winter to speak of, 1277 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 3250 cooling degree days. 27°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 19.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3 on the standard unit fit for this climate. Pascagoula's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,078 kWh a year to keep it warm, plus cooling, for a combined electric bill near $595 a year. Pascagoula's gas rate of $16.64 per Mcf, applied to the 13 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $873 a year, against 15.47¢ per kWh for electricity. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,162 ahead.
How sensitive Pascagoula's result is to prices
In Pascagoula 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 Pascagoula: the heat pump is worth it within a decade if it costs less than $2,770 more than replacing the furnace and AC, and within 7 years if the gap is under $1,939.
Electric resistance heat in Pascagoula, compared
Plenty of homes in Pascagoula heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Pascagoula's answer improves. The saving here runs about $556 a year, which recovers the extra $7,500 spent going electric in roughly 13.5 years.
How Pascagoula compares nationally
Pascagoula lands at position 2764 out of 3206 cities on heating severity (coldest is 1), and 1813 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.
