Heat pump vs. gas furnace in Roseville, MI
In Roseville, a heat pump would cost more to run each year than what you have now. 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). Running costs here land $270 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Roseville's numbers say wait.
The climate behind Roseville's payback figure
4925 heating degree days pile up here every year, so Roseville has a real but manageable winter; the cooling side runs to 868 cooling degree days, where summers add a moderate cooling load. 5.7°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -0.9°F on file. Worked through the model, that's a seasonal COP of 2.84 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Roseville — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,391 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,063 a year. That compares with roughly 51 Mcf a year of gas at Roseville's 10.92 per-Mcf rate — about $793 a year — against a local electricity rate of 20.72¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $7,550 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Roseville — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,754 a year, which recovers the extra $8,000 spent going electric in roughly 4.6 years.
How Roseville compares nationally
Ranked against the other 3206 cities covered, Roseville comes in at 835 for heating severity — 1 would be the coldest place in the dataset — and 872 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
