Bloomington, MN: the heat pump payback math
Bloomington 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 $198 a year here, so the extra spend stays unrecovered. There's no spin on that: Bloomington's numbers say wait.
The climate behind Bloomington's payback figure
Bloomington has a cold winter that leans hard on heating equipment — 6022 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 833 cooling degree days. Sizing runs off the design temperature, not the average day: -7.1°F here (record low -8°F), which works out to a seasonal COP of 2.53 for the cold-climate class of unit this climate calls for. Bloomington 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.

Bloomington's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 6,027 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,056 a year. The gas furnace it replaces burns roughly 63 Mcf a year at 10.98 per Mcf here, for a running cost near $858 a year (electricity here runs 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 $6,469 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Bloomington — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Bloomington's answer improves. About $1,503 a year comes back this way, enough that the 5.3-year payback clears the $8,000 premium comfortably within the equipment's life.
Bloomington against the rest of the country
Bloomington lands at position 218 out of 3206 cities on heating severity (coldest is 1), and 405 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.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Bloomington's 2.53 seasonal COP and payback figure. Bloomington's -7.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
