Springfield, OH: the heat pump payback math
Springfield is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Springfield would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. The heat pump would cost about $35 more a year to run than the furnace it replaces — a premium with no payback. That's Springfield's own climate and rates talking, not a hedge or a caveat.
How cold Springfield actually gets
Springfield has a real but manageable winter — 4651 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 938 cooling degree days. Sizing runs off the design temperature, not the average day: 3°F here (record low 1°F), which works out to a seasonal COP of 2.77 for the cold-climate class of unit this climate calls for. Springfield needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

The month-to-month numbers for Springfield
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,252 kWh a year to keep it warm, plus cooling, for a combined electric bill near $929 a year. Springfield's gas rate of 13.85 per Mcf, applied to the 48 Mcf a year the furnace burns, puts its running cost near $895 a year, against 18.40¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $4,023 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Springfield — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Springfield's answer improves. 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 $8,000 spent up front comes back in about 5.5 years.
How Springfield compares nationally
Springfield lands at position 1042 out of 3206 cities on heating severity (coldest is 1), and 703 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
Next step for 58,138 people in Springfield
Springfield, Ohio is home to about 58,138 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 Springfield, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Springfield's 2.77 seasonal COP and payback figure. Springfield's 3°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.
