Heat Pump Payback in Birmingham, MI
Will a heat pump pay off in Birmingham, MI?
Birmingham is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. The heat pump would cost about $265 more a year to run than the furnace it replaces, a premium with no payback. That's Birmingham's own climate and rates talking, not a hedge or a caveat.

How cold Birmingham actually gets
4971 heating degree days pile up here every year, so Birmingham has a real but manageable winter; the cooling side runs to 954 cooling degree days, where summers add a moderate cooling load. 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. Below the 25°F line where a standard machine starts leaning on resistance backup, Birmingham sits firmly in cold-climate territory, so that's the class of unit priced here.

Birmingham's running-cost comparison, in dollars
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. Birmingham's gas rate of $10.92 per Mcf, applied to the 52 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $822 a year, against 20.72¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $9,480 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Birmingham
For the verdict in Birmingham to flip, electricity would need to drop to about 14.1¢/kWh from 20.72¢, or gas climb past $16.05 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 Birmingham; the case for one here rests on comfort, cooling, or replacing electric heat instead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Birmingham, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,777 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 5.6 years.
How Birmingham compares nationally
Birmingham lands at position 766 out of 3206 cities on heating severity (coldest is 1), and 1768 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
