Heat Pump Payback in Verona, WI
Verona, WI: the heat pump payback math
Verona is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Verona would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $403 a year here, so the extra spend stays unrecovered. There's no spin on that: Verona's numbers say wait.

Why Verona's climate drives this number
5775 heating degree days pile up here every year, so Verona has a cold winter that leans hard on heating equipment; the cooling side runs to 761 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -9°F here (coldest 2024 reading -11°F), which works out to a seasonal COP of 2.48 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Verona, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Verona's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,896 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,235 a year. Verona's gas rate of $10.74 per Mcf, applied to the 60 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $832 a year, against 18.87¢ per kWh for electricity. With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $11,545 behind.
The break-even point in Verona
The heat pump would become the cheaper option in Verona if electricity fell to 11.6¢/kWh (from 18.87¢) or gas rose above $17.44 per Mcf (from $10.74). At today's prices a cheaper quote cannot rescue the gas comparison in Verona, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Gas isn't universal in Verona, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Verona's answer improves. The saving here runs about $1,710 a year, which recovers the extra $10,000 spent going electric in roughly 5.8 years.
Where Verona ranks in this dataset
Ranked against the other 3206 cities covered, Verona comes in at 288 for heating severity, 1 would be the coldest place in the dataset, and 2212 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
