Kansas City, MO: the heat pump payback math
Kansas City 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). Kansas City's residents would see roughly $226 a year back in running costs, putting the payback around 15.5 years. Kansas City's own numbers say this pencils out only in theory, not in practice.
Why Kansas City's climate drives this number
Degree days tell the story here: Kansas City racks up 3750 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1852 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -2.9°F, against a record low of -9°F. That puts the seasonal coefficient of performance at 2.63 for the recommended cold-climate unit. A cold-climate unit is the right call in Kansas City — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Kansas City
Electricity use for heating alone comes out to about 3,610 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $666 a year. That compares with roughly 39 Mcf a year of gas at Kansas City's 14.94 per-Mcf rate — about $891 a year — against a local electricity rate of 12.83¢/kWh. Buy it outright, not incrementally, and payback stretches to 59.8 years; over 15 years the net position sits $116 behind.
Electric resistance heat in Kansas City, compared
Gas isn't universal in Kansas City — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Kansas City's answer improves. About $860 a year comes back this way, enough that the 9.3-year payback clears the $8,000 premium comfortably within the equipment's life.
Kansas City against the rest of the country
Among 3206 cities, Kansas City's winter puts it at rank 1648 for severity, while its size puts it at rank 38 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Where Kansas City's figure comes from
Every constant behind this page — the 2.63 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a -2.9°F design temperature, Kansas City sits in cold-climate territory; the guide to that class of unit explains why.
