Heat pump vs. gas furnace in Muskego, WI
In Muskego, a heat pump would cost more to run each year than what you have now. $3,500 is what Muskego would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Unfortunately the electric bill outweighs the gas bill it replaces by about $438 a year here, so the extra spend stays unrecovered. There's no spin on that: Muskego's numbers say wait.
Why Muskego's climate drives this number
Degree days tell the story here: Muskego racks up 6294 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 394 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: -5.8°F here (record low -11.2°F), which works out to a seasonal COP of 2.56 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Muskego — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, WAUKESHA COUNTY AIRPORT, 12.8 miles from Muskego.
The month-to-month numbers for Muskego
Modelled on a typical 2000-square-foot house, the heat pump draws about 6,225 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,238 a year. That compares with roughly 66 Mcf a year of gas at Muskego's 10.74 per-Mcf rate — about $800 a year — against a local electricity rate of 18.87¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $10,067 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Muskego heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,866 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4.3 years.
Where Muskego ranks in this dataset
Among 3206 cities, Muskego's winter puts it at rank 119 for severity, while its size puts it at rank 1557 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.

Where Muskego's figure comes from
The methodology guide walks through exactly how Muskego's 2.56 seasonal COP and the rest of this page's numbers get built. Muskego's -5.8°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
