Should Prescott Valley switch to a heat pump?
In Prescott Valley, the math is close enough that it comes down to how long you plan to stay. 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. Prescott Valley's residents would see roughly $369 a year back in running costs, putting the payback around 9.5 years. Whether that's worth it in Prescott Valley depends on how many years you expect to own the place.
Why Prescott Valley's climate drives this number
Degree days tell the story here: Prescott Valley racks up 3997 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1590 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 15.1°F here (record low 12°F), which works out to a seasonal COP of 3.06 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Prescott Valley sits firmly in cold-climate territory, so that's the class of unit priced here.

Prescott Valley's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,307 heating kilowatt-hours annually on top of cooling, totalling about $725 a year on electricity. That compares with roughly 42 Mcf a year of gas at Prescott Valley's 18.58 per-Mcf rate — about $1,094 a year — against a local electricity rate of 15.55¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 36.6 years, for a 15-year net position $2,031 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Prescott Valley heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Prescott Valley's answer improves. The saving here runs about $1,169 a year, which recovers the extra $8,000 spent going electric in roughly 6.8 years.
