Heat Pump Payback in Hartland, WI
Heat pump vs. gas furnace in Hartland, WI
In Hartland, a heat pump would cost more to run each year than what you have now. 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 $438 more a year to run than the furnace it replaces, a premium with no payback. That's Hartland's own climate and rates talking, not a hedge or a caveat.

How cold Hartland actually gets
Degree days tell the story here: Hartland 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 (coldest 2024 reading -11.2°F), which works out to a seasonal COP of 2.56 for the cold-climate class of unit this climate calls for. Hartland 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 Waukesha County Airport, the closest NOAA station, 6.5 miles out.
Hartland's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 6,225 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,238 a year. The gas furnace it replaces burns roughly 66 Mcf a year at $10.74 per Mcf here, for a running cost near $800 a year including the old AC (electricity here runs 18.87¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $12,067 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Hartland's answer
For the verdict in Hartland to flip, electricity would need to drop to about 11.6¢/kWh from 18.87¢, or gas climb past $17.42 per Mcf from $10.74. 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 Hartland; 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 Hartland, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,866 a year comes back this way, enough that the 5.4-year payback clears the $10,000 premium comfortably within the equipment's life.
How Hartland compares nationally
Hartland lands at position 124 out of 3206 cities on heating severity (coldest is 1), and 3151 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.

More on how this number was built
Every constant behind this page, the 2.56 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Hartland'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.
