New AC or Heat Pump in Southaven, MS: 2027 Installed Cost
Adjust your home size & electric cost in Southaven, MS
Start with the house: 2,060 sq. ft. calls for about 48,000 BTU, a 4-ton unit. In Southaven, the 16 SEER version of that system costs $10,490 to $12,640 installed and gives the lowest ten-year total of the ratings we price. No markup or discount here: Southaven (about 56,000 residents) follows the Mississippi statewide numbers.
Expect the quote to list the condenser, coil, line set, pad, disconnect and thermostat. Leaky or undersized ducts, an old electrical panel and the permit are the usual extras.

Ten Summers of Cooling Bills in Southaven
The electric rate behind these numbers is the Mississippi residential average, $0.174/kWh, about 20% below the national average of $0.217. A 2.71% yearly rise in Mississippi electric rates, the decade trend, is built into every ten-year number on this page.
Hover or tap any year to see what each rating costs to run that season. Rates rise 2.71% a year, the MS ten-year trend.
The first point applies MS's current rate to this season; every point after it adds another year of the 2.71% average increase. Dollar figures are rounded up to the next $10.
Our model runs the AC about 14.3 hours a day in season. On that basis a 2,060 sq. ft. home in Southaven pays about $1,180 a year at 16 SEER and $2,090 at 9 SEER.
Upgrade Payback Finder: Your Old AC vs a New One
Pick the unit you have and the one you are considering. Figures are for a 4-ton system at Mississippi electric rates ($0.174/kWh, rising 2.71% a year).
| Installed price of the new system | $11,400 |
| Electricity saved, first year | $910 |
| Saved over 10 summers (rates rising) | $10,270 |
| Payback | 11.0 years |
| Net after 10 summers | -$1,140 |
Not on savings alone: 9 to 16 SEER is $1,140 short after 10 summers in MS.
These figures treat the whole install as the price of switching from a unit that still runs. For a dead unit, only the step up from a basic 14 SEER bid has to pay back.

From a 9 SEER starting point, the quickest return in Southaven comes from 16 SEER, about 11.0 years.
Price Plus Running Cost: Southaven Totals
Buy Price vs 10-Year Running Cost: Total Cost of Ownership in MS
For each SEER rating: the installed price, 10 years of cooling electricity at Mississippi rates (rising 2.71% a year), and the two added together. The shortest total bar is the cheapest system to own. Hover or tap a bar for the math.
Cheapest over 10 years in Mississippi: 16 SEER at $24,710 all-in, made of $11,400 to install plus $13,320 to run.
How the electricity bar is built: this season at today's MS rate, then nine more seasons, each raised by the 2.71% yearly increase MS has averaged. Install is the typical price shown on this page. Every figure is rounded up to the next $10 separately, which can leave the parts $10 over the total. 14 SEER is left out: it is below the federal minimum for new central AC installs in Mississippi.

Matching the System to Southaven Weather
In Mississippi, which our map files under climate region 5, summer days average roughly 93°F and winter days roughly 56°F. Those statewide figures feed the Southaven numbers. Cooling season in Southaven starts early and runs late. Winters are shorter but still bring freezing nights.
Climate zones run from 1 (cool) to 5 (hot); Mississippi is in Zone 5.
Southaven sits toward the north end of the Mississippi cities we cover, where winters tend to run longer and colder.
Humid summers add work in Southaven: part of the AC's capacity goes to pulling water out of the air rather than cooling it.
About 180 miles north of Jackson, Southaven has its own housing mix and its own prices.
Heating in Southaven is a lighter job than cooling, so the heat pump or furnace rarely works hard. Climate sets the baseline and the house sets the answer: a tight 2,060 sq. ft. home in Southaven may need less than 4 tons, a leaky or sun-heavy one more.
Ductwork and Space in a Southaven Install
Air handlers tucked into attics, closets or crawlspaces are common in Southaven; tight access adds labor, so mention it up front. Short drives and simple access help explain why Southaven prices sit at or below the Mississippi average.
With ducts in place, central air is usually cheaper; without them, or when you want room-by-room control, ductless wins.
Picking the Right Month in Southaven
The cooler months are when Southaven contractors have the most open dates. Refrigerant work requires EPA certification, and many Mississippi localities require a permit for equipment swaps, so check both before you sign.

The Southaven estimate also gives a fair first number for Horn Lake, Nesbit, Olive Branch, Walls and Hernando.

Quick Answers
Figures below use Mississippi averages; energy prices as of October 2026.
Does a heat pump heat for less than natural gas in Mississippi?
It does in Mississippi: 58,695 BTUs per dollar from a COP-3 heat pump against 52,819 from natural gas. Electricity would have to pass about 19.4¢ per kWh to erase that (the Mississippi average is 17.4¢). Expect the edge to thin in cold snaps, when heat pump efficiency falls.
Is electricity in Mississippi expensive compared with other states?
Mississippi pays 17.4¢ per kWh on average: 20% under the national figure of 21.7¢ and the 15th cheapest of 51. Cooling bills rise and fall with it.
Is a cold-climate heat pump needed in Mississippi?
Rarely. A statewide average winter low near 35°F suits a standard heat pump; sizing and installation quality matter more here.
What does a heat pump save over electric baseboard in Mississippi?
About two-thirds. At 17.4¢ per kWh (the Mississippi average), a million BTU of heat costs about $51.11 from baseboards and about $17.04 from a heat pump running at COP 3.
What is the best season to replace an AC or furnace in Mississippi?
The shoulder seasons, spring and fall, ahead of need. Summer days in Mississippi average about 93°F, so have cooling work done by early spring. The first heat wave and the first cold snap fill every installer's calendar; replacing on your own schedule leaves room to compare quotes.
Is it smart to replace the furnace and AC together?
Often. Two old units replaced in one visit share the labor, and the indoor coil gets matched to the outdoor unit as the rating requires. A young furnace or AC can stay; quote the other separately.
