Should Jenks switch to a heat pump?
The payback math works in Jenks on paper, past the equipment's own working life. $3,500 is what Jenks 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 $218 of lower running costs every year, landing the payback clock at roughly 16.1 years. Jenks's own numbers say this pencils out only in theory, not in practice.
Why Jenks's climate drives this number
Degree days tell the story here: Jenks racks up 2849 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2308 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 6.1°F, against a record low of -0.9°F. That puts the seasonal coefficient of performance at 2.85 for the recommended cold-climate unit. Jenks 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.

Jenks's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 2,531 heating kilowatt-hours annually on top of cooling, totalling about $589 a year on electricity. The gas furnace it replaces burns roughly 30 Mcf a year at 13.99 per Mcf here, for a running cost near $807 a year (electricity here runs 13.10¢/kWh). Buy it outright, not incrementally, and payback stretches to 62.1 years; over 15 years the net position sits $237 behind.
Electric resistance heat in Jenks, compared
Gas isn't universal in Jenks — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Jenks's answer improves. The saving here runs about $747 a year, which recovers the extra $8,000 spent going electric in roughly 10.7 years.
Jenks against the rest of the country
Among 3206 cities, Jenks's winter puts it at rank 1968 for severity, while its size puts it at rank 1436 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
Deciding what's next in Jenks, OK
About 27,869 people live in Jenks, Oklahoma, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Where Jenks's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Jenks's 2.85 seasonal COP and payback figure. Jenks's 6.1°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.
