Tremonton, UT: the heat pump payback math
The payback math works in Tremonton 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). Tremonton's residents would see roughly $46 a year back in running costs, putting the payback around 76.2 years. Tremonton's own numbers say this pencils out only in theory, not in practice.
Why Tremonton's climate drives this number
Tremonton has a real but manageable winter — 4861 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1237 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 11.7°F, against a record low of -5.1°F. That puts the seasonal coefficient of performance at 2.98 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Tremonton sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from BRIGHAM CITY AIRPORT, the closest NOAA station, 13.2 miles out.
Tremonton's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,130 heating kilowatt-hours annually on top of cooling, totalling about $680 a year on electricity. That compares with roughly 51 Mcf a year of gas at Tremonton's 10.19 per-Mcf rate — about $726 a year — against a local electricity rate of 13.12¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 294 years, for a 15-year net position $2,811 behind.
If your home heats with electric baseboard instead of gas
Not every home in Tremonton has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,145 a year comes back this way, enough that the 7-year payback clears the $8,000 premium comfortably within the equipment's life.
How Tremonton compares nationally
Among 3206 cities, Tremonton's winter puts it at rank 893 for severity, while its size puts it at rank 2702 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Tremonton
About 12,677 people live in Tremonton, 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.
Ask a local HVAC contractor for a quote before committing either way.
