Heat Pump Payback in Las Vegas, NV
Las Vegas, NV: the heat pump payback math
This one's marginal in Las Vegas: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Lower bills claw that back: about $319 saved annually, for a payback of roughly 9.4 years. Whether that's worth it in Las Vegas depends on how many years you expect to own the place.

The climate behind Las Vegas's payback figure
Las Vegas has a mild winter by US standards, 1795 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4522 cooling degree days. 28.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 28°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.06 on the standard unit fit for this climate. A standard ducted system is enough here; Las Vegas's design temperature doesn't justify the cold-climate premium. These numbers come from North Las Vegas Airport, the closest NOAA station, 4.1 miles out.
Las Vegas's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 1,485 heating kilowatt-hours annually on top of cooling, totalling about $750 a year on electricity. That compares with roughly 19 Mcf a year of gas at Las Vegas's $13.14 per-Mcf rate, about $1,068 a year with the old AC included, against a local electricity rate of 14.04¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,779 ahead.
How sensitive Las Vegas's result is to prices
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Las Vegas at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $319 a year saved, a difference under $2,233 pays back within 7 years here, and under $3,190 within 10.
If your home heats with electric baseboard instead of gas
Not every home in Las Vegas has gas service. Swap the comparison to resistance heat instead of gas, and Las Vegas's answer improves. About $711 a year comes back this way, enough that the 10.5-year payback clears the $7,500 premium comfortably within the equipment's life.
How Las Vegas compares nationally
Ranked against the other 3206 cities covered, Las Vegas comes in at 2544 for heating severity, 1 would be the coldest place in the dataset, and 24 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.
