Should Davidson switch to a heat pump?
In Davidson, the math is close enough that it comes down to how long you plan to stay. $3,500 is what Davidson 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. Davidson's residents would see roughly $254 a year back in running costs, putting the payback around 13.8 years. Whether that's worth it in Davidson depends on how many years you expect to own the place.
Why Davidson's climate drives this number
Degree days tell the story here: Davidson racks up 2683 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1734 cooling degree days on the cooling side. 19.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12.2°F on file. Worked through the model, that's a seasonal COP of 3.17 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Davidson — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Davidson
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,143 kWh a year to keep it warm, plus cooling, for a combined electric bill near $541 a year. The gas furnace it replaces burns roughly 28 Mcf a year at 16.42 per Mcf here, for a running cost near $794 a year (electricity here runs 14.93¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 53.2 years, for a 15-year net position $304 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Davidson heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Davidson's answer improves. Switching saves about $809 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 9.9 years.
Where Davidson ranks in this dataset
Davidson lands at position 2049 out of 3206 cities on heating severity (coldest is 1), and 2269 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Davidson's 3.17 seasonal COP and payback figure. Davidson's 19.4°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
