Crystal, MN: the heat pump payback math
Crystal is a place where a heat pump genuinely costs more to operate than the alternative. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Unfortunately the electric bill outweighs the gas bill it replaces by about $213 a year here, so the extra spend stays unrecovered. There's no spin on that: Crystal's numbers say wait.
The climate behind Crystal's payback figure
Crystal has a cold winter that leans hard on heating equipment — 6208 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 735 cooling degree days. -7.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -9°F on file. Worked through the model, that's a seasonal COP of 2.53 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Crystal sits firmly in cold-climate territory, so that's the class of unit priced here.

The month-to-month numbers for Crystal
Electricity use for heating alone comes out to about 6,213 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,072 a year. That compares with roughly 65 Mcf a year of gas at Crystal's 10.98 per-Mcf rate — about $859 a year — against a local electricity rate of 15.67¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $6,690 behind.
Electric resistance heat in Crystal, compared
Not every home in Crystal 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. Switching saves about $1,541 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 5.2 years.
Crystal against the rest of the country
Among 3206 cities, Crystal's winter puts it at rank 154 for severity, while its size puts it at rank 1776 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

About 22,082 people live in Crystal, Minnesota, 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, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Where Crystal's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Crystal's 2.53 seasonal COP and payback figure. Crystal's -7.1°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
