Heat Pump Payback in Lee's Summit, MO
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 $5,500 more up front here. Lee's Summit's residents would see roughly $210 a year back in running costs, putting the payback around 26.2 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 low of -9°F in the 2024 station record. 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 with the old AC included, against a local electricity rate of 12.83¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $2,351 behind.
The break-even point in Lee's Summit
Gas would only overtake the heat pump in Lee's Summit if electricity rose past 20.2¢/kWh from 12.83¢, or gas fell under $9.50 per Mcf from $14.94. A useful quote test for Lee's Summit: the heat pump is worth it within a decade if it costs less than $2,100 more than replacing the furnace and AC, and within 7 years if the gap is under $1,470.
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 $10,000 spent going electric in roughly 11.9 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.
