El Dorado, KS: the heat pump payback math
The payback math works in El Dorado on paper, past the equipment's own working life. $3,500 is what El Dorado 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. That premium is recovered through $161 of lower running costs every year, landing the payback clock at roughly 21.8 years. El Dorado's own numbers say this pencils out only in theory, not in practice.
The climate behind El Dorado's payback figure
3737 heating degree days pile up here every year, so El Dorado has a real but manageable winter; the cooling side runs to 1733 cooling degree days, where summers are hot enough that cooling matters as much as heating. -0.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -5.1°F on file. Worked through the model, that's a seasonal COP of 2.68 on the cold-climate unit fit for this climate. El Dorado 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. Climate figures trace to the nearest NOAA station, COLONEL JAMES JABARA ARPT, 20.2 miles from El Dorado.
The month-to-month numbers for El Dorado
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,531 kWh a year to keep it warm, plus cooling, for a combined electric bill near $754 a year. El Dorado's gas rate of 14.81 per Mcf, applied to the 39 Mcf a year the furnace burns, puts its running cost near $914 a year, against 15.05¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 84 years; over 15 years the net position sits $1,090 behind.
The other scenario: no gas furnace to begin with
Not every home in El Dorado has gas service. Swap the comparison to resistance heat instead of gas, and El Dorado's answer improves. Switching saves about $1,008 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 7.9 years.
El Dorado against the rest of the country
Among 3206 cities, El Dorado's winter puts it at rank 1657 for severity, while its size puts it at rank 2700 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Nothing above is a black box: the methodology guide shows the full arithmetic behind El Dorado's 2.68 seasonal COP and payback figure. El Dorado's -0.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
