Heat Pump Payback in Westland, MI
Westland, MI: the heat pump payback math
Here in Westland, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $300 a year here, so the extra spend stays unrecovered. That's Westland's own climate and rates talking, not a hedge or a caveat.

How cold Westland actually gets
5000 heating degree days pile up here every year, so Westland has a cold winter that leans hard on heating equipment; the cooling side runs to 928 cooling degree days, where summers add a moderate cooling load. 1.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -2.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.75 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Westland, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Detroit Metro Wayne County Ai, the closest NOAA station, 6.6 miles out.
The yearly running costs in Westland
A 2000-square-foot house here would pull roughly 4,604 heating kilowatt-hours annually on top of cooling, totalling about $1,118 a year on electricity. That compares with roughly 52 Mcf a year of gas at Westland's $10.92 per-Mcf rate, about $818 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: $10,000 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Westland
For the verdict in Westland to flip, electricity would need to drop to about 13.6¢/kWh from 20.72¢, or gas climb past $16.68 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 Westland; 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 Westland 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. Switching saves about $1,755 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 5.7 years.

Where Westland's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Westland's 2.75 seasonal COP and payback figure. Westland's 1.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
