Reedsburg, WI: the heat pump payback math
Reedsburg 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 $3,500 after a $2,000 federal tax credit. Running costs here land $394 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Reedsburg's numbers say wait.
The climate behind Reedsburg's payback figure
Reedsburg has a cold winter that leans hard on heating equipment — 5845 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 668 cooling degree days. -6.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -10.5°F on file. Worked through the model, that's a seasonal COP of 2.53 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Reedsburg sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from BARABOO WISCONSIN DELLS AIRPO, the closest NOAA station, 11.1 miles out.
Reedsburg's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,850 heating kilowatt-hours annually on top of cooling, totalling about $1,211 a year on electricity. That compares with roughly 61 Mcf a year of gas at Reedsburg's 10.74 per-Mcf rate — about $817 a year — against a local electricity rate of 18.87¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $9,413 behind.
The other scenario: no gas furnace to begin with
Not every home in Reedsburg has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,745 a year comes back this way, enough that the 4.6-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Reedsburg ranks in this dataset
Among 3206 cities, Reedsburg's winter puts it at rank 276 for severity, while its size puts it at rank 3121 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.

More on how this number was built
Every constant behind this page — the 2.53 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Reedsburg's -6.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
