Champlin, MN: the heat pump payback math
In Champlin, a heat pump would cost more to run each year than what you have now. $3,500 is what Champlin would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. The heat pump would cost about $213 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Champlin's numbers say wait.
Why Champlin's climate drives this number
6208 heating degree days pile up here every year, so Champlin has a cold winter that leans hard on heating equipment; the cooling side runs to 735 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -7.1°F, against a record low of -9°F. That puts the seasonal coefficient of performance at 2.53 for the recommended cold-climate unit. Champlin 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.

The month-to-month numbers for Champlin
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. Champlin's gas rate of 10.98 per Mcf, applied to the 65 Mcf a year the furnace burns, puts its running cost near $859 a year, against 15.67¢ per kWh for electricity. 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.
If your home heats with electric baseboard instead of gas
Plenty of homes in Champlin heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Champlin's answer improves. The saving here runs about $1,541 a year, which recovers the extra $8,000 spent going electric in roughly 5.2 years.
How Champlin compares nationally
Among 3206 cities, Champlin's winter puts it at rank 152 for severity, while its size puts it at rank 1714 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 23,045 people live in Champlin, 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.
More on how this number was built
The methodology guide walks through exactly how Champlin's 2.53 seasonal COP and the rest of this page's numbers get built. Champlin's -7.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
