HeatPumpPayback

Boulder City, NV: the heat pump payback math

In Boulder City, a heat pump pays for itself within a reasonable window. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $296 of lower running costs every year, landing the payback clock at roughly 3.4 years. That's a real payback, built from Boulder City's own climate and utility rates, not a national guess.

Why Boulder City's climate drives this number

Degree days tell the story here: Boulder City racks up 1933 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 4120 cooling degree days on the cooling side. 28.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 24.8°F on file. Worked through the model, that's a seasonal COP of 3.05 on the standard unit fit for this climate. A standard ducted system is enough here; Boulder City's design temperature doesn't justify the cold-climate premium.

The month-to-month numbers for Boulder City

A 2000-square-foot house here would pull roughly 1,605 heating kilowatt-hours annually on top of cooling, totalling about $719 a year on electricity. Boulder City's gas rate of 13.14 per Mcf, applied to the 20 Mcf a year the furnace burns, puts its running cost near $1,014 a year, against 14.04¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 37.2 years, for a 15-year net position $3,435 ahead.

If your home heats with electric baseboard instead of gas

Not every home in Boulder City has gas service. Swap the comparison to resistance heat instead of gas, and Boulder City's answer improves. Switching saves about $718 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 7.7 years.

Where Boulder City ranks in this dataset

Among 3206 cities, Boulder City's winter puts it at rank 2455 for severity, while its size puts it at rank 2392 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.

What to do with this number in Boulder City

About 15,029 people live in Boulder City, Nevada, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, it's worth getting quotes before your current system fails, not after.
