Heat Pump Payback in Saginaw, MI
Heat pump vs. gas furnace in Saginaw, MI
In Saginaw, 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 $5,500 more up front here. Running costs here land $406 a year higher than the furnace it replaces, so that premium is never recovered. That's Saginaw's own climate and rates talking, not a hedge or a caveat.

Saginaw's weather, in the numbers that matter
Saginaw has a cold winter that leans hard on heating equipment, 5603 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 630 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -1.1°F, and the coldest daily reading in the 2024 station record was -2.4°F. That puts the seasonal coefficient of performance at 2.67 for the recommended cold-climate unit. Saginaw 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. Source: NOAA station Sagnaw Co H.W. Browne Airport, 4.5 miles from Saginaw, the closest one on record.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 5,314 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,212 a year. That compares with roughly 58 Mcf a year of gas at Saginaw's $10.92 per-Mcf rate, about $806 a year with the old AC included, against a local electricity rate of 20.72¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $11,589 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Saginaw
For the verdict in Saginaw to flip, electricity would need to drop to about 12.7¢/kWh from 20.72¢, or gas climb past $17.88 per Mcf from $10.92. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Saginaw; the case for one here rests on comfort, cooling, or replacing electric heat instead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Saginaw heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,897 a year, which recovers the extra $10,000 spent going electric in roughly 5.3 years.
Saginaw against the rest of the country
Among 3206 cities, Saginaw's winter puts it at rank 339 for severity, while its size puts it at rank 956 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.
