How cold Paradise Valley actually gets
Degree days tell the story here: Paradise Valley racks up 1113 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 4618 cooling degree days on the cooling side. 30.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 30.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.12 on the standard unit fit for this climate. Paradise Valley's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

Paradise Valley's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 903 kWh a year to keep it warm, plus cooling, for a combined electric bill near $753 a year. Paradise Valley's gas rate of $18.58 per Mcf, applied to the 12 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,146 a year, against 15.55¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $2,899 ahead.
The break-even point in Paradise Valley
In Paradise Valley the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Paradise Valley: the heat pump is worth it within a decade if it costs less than $3,930 more than replacing the furnace and AC, and within 7 years if the gap is under $2,751.
If your home heats with electric baseboard instead of gas
Not every home in Paradise Valley has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $616 a year, which recovers the extra $7,500 spent going electric in roughly 12.2 years.
