Heat Pump Payback in Royal Oak, MI
Will a heat pump pay off in Royal Oak, MI?
In Royal Oak, 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 $265 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Royal Oak's numbers say wait.

Why Royal Oak's climate drives this number
Royal Oak has a real but manageable winter, 4971 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 954 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 5.9°F, and the coldest daily reading in the 2024 station record was -2.4°F. That puts the seasonal coefficient of performance at 2.84 for the recommended cold-climate unit. Royal Oak 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 Oakland/Troy Airport, the closest NOAA station, 2.7 miles out.
The yearly running costs in Royal Oak
Electricity use for heating alone comes out to about 4,432 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,087 a year. The gas furnace it replaces burns roughly 52 Mcf a year at $10.92 per Mcf here, for a running cost near $822 a year including the old AC (electricity here runs 20.72¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $9,480 behind.
How sensitive Royal Oak's result is to prices
The heat pump would become the cheaper option in Royal Oak if electricity fell to 14.1¢/kWh (from 20.72¢) or gas rose above $16.05 per Mcf (from $10.92). At today's prices a cheaper quote cannot rescue the gas comparison in Royal Oak, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Not every home in Royal Oak has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,777 a year, which recovers the extra $10,000 spent going electric in roughly 5.6 years.
Where Royal Oak ranks in this dataset
