Should Sahuarita switch to a heat pump?
In Sahuarita, a heat pump is the cheaper choice, and not by a little. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. That premium is recovered through $357 of lower running costs every year, landing the payback clock at roughly 2.8 years. Nothing about that conclusion is generic — it's built entirely from Sahuarita's own numbers.
Why Sahuarita's climate drives this number
Sahuarita barely has a winter to speak of — 1346 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 3913 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 28.9°F, against a record low of 28°F. That puts the seasonal coefficient of performance at 3.06 for the recommended standard unit. A standard ducted system is enough here; Sahuarita's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,114 heating kilowatt-hours annually on top of cooling, totalling about $692 a year on electricity. That compares with roughly 14 Mcf a year of gas at Sahuarita's 18.58 per-Mcf rate — about $1,049 a year — against a local electricity rate of 15.55¢/kWh. Buy it outright, not incrementally, and payback stretches to 30.8 years; over 15 years the net position sits $4,356 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Sahuarita has gas service. Swap the comparison to resistance heat instead of gas, and Sahuarita's answer improves. Switching saves about $627 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 8.8 years.
Where Sahuarita ranks in this dataset
Ranked against the other 3206 cities covered, Sahuarita comes in at 2749 for heating severity — 1 would be the coldest place in the dataset — and 1110 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
