Heat Pump Payback in Magna, UT
Heat pump vs. gas furnace in Magna, UT
The payback math works in Magna on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. That premium is recovered through $110 of lower running costs every year, landing the payback clock at roughly 50.2 years. Magna's own numbers say this pencils out only in theory, not in practice.

Why Magna's climate drives this number
4667 heating degree days pile up here every year, so Magna has a real but manageable winter; the cooling side runs to 1804 cooling degree days, where summers are hot enough that cooling matters as much as heating. 19°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 12.2°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.16 on the cold-climate unit fit for this climate. Magna 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, 11.3 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 3,740 heating kilowatt-hours annually on top of cooling, totalling about $692 a year on electricity. That compares with roughly 49 Mcf a year of gas at Magna's $10.19 per-Mcf rate, about $802 a year with the old AC included, against a local electricity rate of 13.12¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $3,856 behind.
The break-even point in Magna
This result holds unless electricity climbs above 16.8¢/kWh (it is 13.12¢ now) or gas drops below $7.94 per Mcf (now $10.19); past either point, gas becomes the cheaper fuel in Magna. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $110 a year saved, a difference under $770 pays back within 7 years here, and under $1,100 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Magna 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. The saving here runs about $1,165 a year, which recovers the extra $10,000 spent going electric in roughly 8.6 years.
Where Magna ranks in this dataset
Ranked against the other 3206 cities covered, Magna comes in at 1034 for heating severity, 1 would be the coldest place in the dataset, and 1305 by population, where 1 is largest. 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 Magna
About 31,381 people live in Magna, 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
Every constant behind this page, the 3.16 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. At a 19°F design temperature, Magna sits in cold-climate territory; the guide to that class of unit explains why.
