Will a heat pump pay off in Topeka, KS?
The payback math works in Topeka on paper, past the equipment's own working life. 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 $143 saved annually, for a payback of roughly 24.5 years. That's a technicality, not a recommendation, for anyone actually living in Topeka.
How cold Topeka actually gets
Degree days tell the story here: Topeka racks up 3960 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1753 cooling degree days on the cooling side. -5.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -8°F on file. Worked through the model, that's a seasonal COP of 2.58 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Topeka sits firmly in cold-climate territory, so that's the class of unit priced here.

The month-to-month numbers for Topeka
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,887 kWh a year to keep it warm, plus cooling, for a combined electric bill near $810 a year. Topeka's gas rate of 14.81 per Mcf, applied to the 41 Mcf a year the furnace burns, puts its running cost near $953 a year, against 15.05¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 94.5 years; over 15 years the net position sits $1,357 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Topeka — 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. Switching saves about $1,041 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 7.7 years.
Topeka against the rest of the country
Among 3206 cities, Topeka's winter puts it at rank 1556 for severity, while its size puts it at rank 232 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Where Topeka's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Topeka's 2.58 seasonal COP and payback figure. Topeka's -5.1°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.
