Is a heat pump worth it in Smithville?
The payback math works in Smithville on paper, past the equipment's own working life. 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). Smithville's residents would see roughly $195 a year back in running costs, putting the payback around 18 years. Smithville's own numbers say this pencils out only in theory, not in practice.
The climate behind Smithville's payback figure
Smithville has a real but manageable winter — 4235 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1401 cooling degree days. Sizing runs off the design temperature, not the average day: -7.1°F here (record low -16.1°F), which works out to a seasonal COP of 2.53 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Smithville sits firmly in cold-climate territory, so that's the class of unit priced here.

The month-to-month numbers for Smithville
A 2000-square-foot house here would pull roughly 4,239 heating kilowatt-hours annually on top of cooling, totalling about $697 a year on electricity. Smithville's gas rate of 14.94 per Mcf, applied to the 44 Mcf a year the furnace burns, puts its running cost near $892 a year, against 12.83¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 69.3 years; over 15 years the net position sits $578 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Smithville — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Smithville's answer improves. About $912 a year comes back this way, enough that the 8.8-year payback clears the $8,000 premium comfortably within the equipment's life.
How Smithville compares nationally
Among 3206 cities, Smithville's winter puts it at rank 1386 for severity, while its size puts it at rank 2990 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
