Should Southaven switch to a heat pump?
Southaven sits right on the fence — how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $265 saved annually, for a payback of roughly 13.2 years. Whether that's worth it in Southaven depends on how many years you expect to own the place.
Why Southaven's climate drives this number
Degree days tell the story here: Southaven racks up 2396 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2383 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 12°F here (record low 1.9°F), which works out to a seasonal COP of 2.99 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Southaven — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, MEMPHIS INTERNATIONAL AIRPORT, 7.3 miles from Southaven.
The month-to-month numbers for Southaven
Electricity use for heating alone comes out to about 2,029 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $628 a year. Southaven's gas rate of 16.64 per Mcf, applied to the 25 Mcf a year the furnace burns, puts its running cost near $893 a year, against 15.47¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 51 years, leaving the 15-year total $472 ahead.
Electric resistance heat in Southaven, compared
Not every home in Southaven has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $788 a year comes back this way, enough that the 10.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Southaven ranks in this dataset
Among 3206 cities, Southaven's winter puts it at rank 2238 for severity, while its size puts it at rank 712 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.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Southaven's 2.99 seasonal COP and payback figure. Southaven's 12°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.
