Heat Pump Payback in Chandler, AZ
Heat pump vs. gas furnace in Chandler, AZ
Chandler clears a genuine payback here, inside a reasonable stretch of years. $3,000 is what Chandler would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $411 of lower running costs every year, landing the payback clock at roughly 7.3 years. The window here is reasonable, and it's specific to what Chandler actually pays for power and gas.

Chandler's weather, in the numbers that matter
Chandler barely has a winter to speak of, 761 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 5206 cooling degree days. 32°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 32°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.15 on the standard unit fit for this climate. Chandler's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 612 heating kilowatt-hours annually on top of cooling, totalling about $785 a year on electricity. Chandler's gas rate of $18.58 per Mcf, applied to the 8 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,196 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 $3,166 ahead.
How sensitive Chandler's result is to prices
In Chandler 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 Chandler: the heat pump is worth it within a decade if it costs less than $4,110 more than replacing the furnace and AC, and within 7 years if the gap is under $2,877.
Electric resistance heat in Chandler, compared
Gas isn't universal in Chandler, many houses run on electric heat already. 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 $563 a year, which recovers the extra $7,500 spent going electric in roughly 13.3 years.
Where Chandler ranks in this dataset
Among 3206 cities, Chandler's winter puts it at rank 2981 for severity, while its size puts it at rank 79 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
Next step if you live in Chandler
Chandler, Arizona is home to about 281,231 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. Given the math above, Chandler is a place worth lining up quotes ahead of a breakdown, not waiting for one.
Ask a local HVAC contractor for a quote before committing either way.
