Is a heat pump worth it in Tooele?
Tooele 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). Lower bills claw that back: about $71 saved annually, for a payback of roughly 49.2 years. Tooele's own numbers say this pencils out only in theory, not in practice.
The climate behind Tooele's payback figure
Tooele has a cold winter that leans hard on heating equipment — 5289 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1255 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 17.6°F, against a record low of 10.4°F. That puts the seasonal coefficient of performance at 3.12 for the recommended cold-climate unit. A cold-climate unit is the right call in Tooele — 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 Tooele
Electricity use for heating alone comes out to about 4,292 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $704 a year. Tooele's gas rate of 10.19 per Mcf, applied to the 55 Mcf a year the furnace burns, puts its running cost near $775 a year, against 13.12¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 189.8 years, leaving the 15-year total $2,433 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Tooele heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,267 a year comes back this way, enough that the 6.3-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Tooele ranks in this dataset
Tooele lands at position 490 out of 3206 cities on heating severity (coldest is 1), and 1001 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
Next step for 40,919 people in Tooele
About 40,919 people live in Tooele, Utah, 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.

More on how this number was built
The methodology guide walks through exactly how Tooele's 3.12 seasonal COP and the rest of this page's numbers get built. At a 17.6°F design temperature, Tooele sits in cold-climate territory; the guide to that class of unit explains why.
