Will a heat pump pay off in Lee's Summit, MO?
Lee's Summit technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lee's Summit's residents would see roughly $210 a year back in running costs, putting the payback around 16.7 years. That's a technicality, not a recommendation, for anyone actually living in Lee's Summit.
Lee's Summit's weather, in the numbers that matter
Lee's Summit has a real but manageable winter — 3709 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1693 cooling degree days. -4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -9°F on file. Worked through the model, that's a seasonal COP of 2.6 on the cold-climate unit fit for this climate. Lee's Summit 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.

Lee's Summit's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,612 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $649 a year. That compares with roughly 39 Mcf a year of gas at Lee's Summit's 14.94 per-Mcf rate — about $859 a year — against a local electricity rate of 12.83¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 64.3 years, leaving the 15-year total $351 behind.
Electric resistance heat in Lee's Summit, compared
Gas isn't universal in Lee's Summit — 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. The saving here runs about $838 a year, which recovers the extra $8,000 spent going electric in roughly 9.5 years.
Where Lee's Summit ranks in this dataset
Lee's Summit lands at position 1671 out of 3206 cities on heating severity (coldest is 1), and 306 out of 3206 by population size (biggest is 1). 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 Lee's Summit's 2.6 seasonal COP and payback figure. Lee's Summit's -4°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.
