Heat Pump Payback in Aberdeen, SD
Should Aberdeen switch to a heat pump?
Here in Aberdeen, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Aberdeen would pay extra to go electric rather than replace the furnace and AC with the same again. The heat pump would cost about $321 more a year to run than the furnace it replaces, a premium with no payback. There's no spin on that: Aberdeen's numbers say wait.

The climate behind Aberdeen's payback figure
Degree days tell the story here: Aberdeen racks up 6970 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 714 cooling degree days on the cooling side. -16.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -18°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.31 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Aberdeen, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Aberdeen Regional Airport, the closest NOAA station, 3.1 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 7,640 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,167 a year. That compares with roughly 73 Mcf a year of gas at Aberdeen's $9.86 per-Mcf rate, about $847 a year with the old AC included, against a local electricity rate of 14.15¢/kWh. With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $10,308 behind.
The break-even point in Aberdeen
The heat pump would become the cheaper option in Aberdeen if electricity fell to 9.8¢/kWh (from 14.15¢) or gas rose above $14.28 per Mcf (from $9.86). At today's prices a cheaper quote cannot rescue the gas comparison in Aberdeen, since there is no yearly saving to recover it from.
Electric resistance heat in Aberdeen, compared
Gas isn't universal in Aberdeen, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,461 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 6.8 years.
Aberdeen against the rest of the country
Among 3206 cities, Aberdeen's winter puts it at rank 48 for severity, while its size puts it at rank 1433 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

More on how this number was built
Every constant behind this page, the 2.31 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. At a -16.1°F design temperature, Aberdeen sits in cold-climate territory; the guide to that class of unit explains why.
