Why D'Iberville's climate drives this number
1081 heating degree days pile up here every year, so D'Iberville barely has a winter to speak of; the cooling side runs to 3323 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 29.3°F here (coldest 2024 reading 19.4°F), which works out to a seasonal COP of 3.07 for the standard class of unit this climate calls for. A standard ducted system is enough here; D'Iberville's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, Keesler Air Force Base, 2.2 miles from D'Iberville.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 892 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $576 a year. That compares with roughly 11 Mcf a year of gas at D'Iberville's $16.64 per-Mcf rate, about $854 a year with the old AC included, against a local electricity rate of 15.47¢/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 $1,160 ahead.
The break-even point in D'Iberville
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in D'Iberville at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $277 a year saved, a difference under $1,939 pays back within 7 years here, and under $2,770 within 10.
Electric resistance heat in D'Iberville, compared
Plenty of homes in D'Iberville heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $513 a year, which recovers the extra $7,500 spent going electric in roughly 14.6 years.
Where D'Iberville ranks in this dataset
D'Iberville lands at position 2862 out of 3206 cities on heating severity (coldest is 1), and 2601 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 D'Iberville
About 13,399 people live in D'Iberville, Mississippi, and every number on this page is what a contractor would actually work from when quoting a system here, the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
Where D'Iberville's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind D'Iberville's 3.07 seasonal COP and payback figure. Not every home in D'Iberville has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
