Will a heat pump pay off in Moss Point, MS?
A heat pump earns back its extra cost in Moss Point within a sensible timeframe. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $277 of lower running costs every year, landing the payback clock at roughly 3.6 years. That's a real payback, built from Moss Point's own climate and utility rates, not a national guess.
The climate behind Moss Point's payback figure
Degree days tell the story here: Moss Point racks up 1277 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3250 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 27°F, against a record low of 19.9°F. That puts the seasonal coefficient of performance at 3 for the recommended standard unit. A standard ducted system is enough here; Moss Point's design temperature doesn't justify the cold-climate premium. These numbers come from TRENT LOTT INTL AIRPORT, the closest NOAA station, 2.6 miles out.
Moss Point's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 1,078 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $595 a year. Moss Point's gas rate of 16.64 per Mcf, applied to the 13 Mcf a year the furnace burns, puts its running cost near $873 a year, against 15.47¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 39.6 years, leaving the 15-year total $3,162 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Moss Point has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $556 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 9.9 years.
How Moss Point compares nationally
Among 3206 cities, Moss Point's winter puts it at rank 2767 for severity, while its size puts it at rank 2842 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
