Is a heat pump worth it in West St. Paul?
West St. Paul is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Unfortunately the electric bill outweighs the gas bill it replaces by about $184 a year here, so the extra spend stays unrecovered. There's no spin on that: West St. Paul's numbers say wait.
Why West St. Paul's climate drives this number
West St. Paul has a cold winter that leans hard on heating equipment — 5994 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 749 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -5.1°F, against a record low of -8°F. That puts the seasonal coefficient of performance at 2.58 for the recommended cold-climate unit. West St. Paul needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 5,883 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,022 a year. The gas furnace it replaces burns roughly 62 Mcf a year at 10.98 per Mcf here, for a running cost near $838 a year (electricity here runs 15.67¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $6,265 behind.
If your home heats with electric baseboard instead of gas
Not every home in West St. Paul has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,509 a year comes back this way, enough that the 5.3-year payback clears the $8,000 premium comfortably within the equipment's life.
West St. Paul against the rest of the country
West St. Paul lands at position 236 out of 3206 cities on heating severity (coldest is 1), and 1791 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.

About 21,920 people live in West St. Paul, 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.
Ask a local HVAC contractor for a quote before committing either way.

The methodology guide walks through exactly how West St. Paul's 2.58 seasonal COP and the rest of this page's numbers get built. West St. Paul's -5.1°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.
