Is a heat pump worth it in South Jordan?
In South Jordan, the extra upfront cost technically comes back, just not before the equipment wears out. 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). That premium is recovered through $110 of lower running costs every year, landing the payback clock at roughly 31.9 years. South Jordan's own numbers say this pencils out only in theory, not in practice.
The climate behind South Jordan's payback figure
Degree days tell the story here: South Jordan racks up 4667 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1804 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 19°F, against a record low of 12.2°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. South Jordan 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. These numbers come from SALT LAKE CITY INTERNATIONAL, the closest NOAA station, 15.5 miles out.
South Jordan's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,740 kWh a year to keep it warm, plus cooling, for a combined electric bill near $692 a year. South Jordan's gas rate of 10.19 per Mcf, applied to the 49 Mcf a year the furnace burns, puts its running cost near $802 a year, against 13.12¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 123.2 years, for a 15-year net position $1,856 behind.
Electric resistance heat in South Jordan, compared
Plenty of homes in South Jordan heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and South Jordan's answer improves. The saving here runs about $1,165 a year, which recovers the extra $8,000 spent going electric in roughly 6.9 years.
How South Jordan compares nationally
Among 3206 cities, South Jordan's winter puts it at rank 1024 for severity, while its size puts it at rank 419 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.

Where South Jordan's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind South Jordan's 3.16 seasonal COP and payback figure. South Jordan's 19°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.
