Heat Pump Payback in Greenwood, MS
Is a heat pump worth it in Greenwood?
Greenwood technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $280 of lower running costs every year, landing the payback clock at roughly 19.7 years. That's a technicality, not a recommendation, for anyone actually living in Greenwood.

How cold Greenwood actually gets
1903 heating degree days pile up here every year, so Greenwood has a mild winter by US standards; the cooling side runs to 2708 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 19°F, and the coldest daily reading in the 2024 station record was 9°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 19°F design temperature Greenwood falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,525 kWh a year to keep it warm, plus cooling, for a combined electric bill near $593 a year. Greenwood's gas rate of $16.64 per Mcf, applied to the 20 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. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,306 behind.
How sensitive Greenwood's result is to prices
Gas would only overtake the heat pump in Greenwood if electricity rose past 101.7¢/kWh from 15.47¢, or gas fell under $2.53 per Mcf from $16.64. A useful quote test for Greenwood: the heat pump is worth it within a decade if it costs less than $2,800 more than replacing the furnace and AC, and within 7 years if the gap is under $1,960.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Greenwood, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $695 a year comes back this way, enough that the 14.4-year payback clears the $10,000 premium comfortably within the equipment's life.
Greenwood against the rest of the country
Ranked against the other 3206 cities covered, Greenwood comes in at 2482 for heating severity, 1 would be the coldest place in the dataset, and 2569 by population, where 1 is largest. 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 Greenwood
Greenwood, Mississippi is home to about 13,627 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Greenwood, nothing is lost by holding off until the current equipment genuinely fails.

Where Greenwood's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Greenwood's 3.16 seasonal COP and payback figure. Greenwood's 19°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
