Will a heat pump pay off in Buffalo, MN?
In Buffalo, a heat pump would cost more to run each year than what you have now. 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). The heat pump would cost about $273 more a year to run than the furnace it replaces — a premium with no payback. That's Buffalo's own climate and rates talking, not a hedge or a caveat.
Buffalo's weather, in the numbers that matter
Buffalo has a cold winter that leans hard on heating equipment — 6678 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 524 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -9.4°F, against a record low of -14.8°F. That puts the seasonal coefficient of performance at 2.47 for the recommended cold-climate unit. A cold-climate unit is the right call in Buffalo — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Buffalo
Modelled on a typical 2000-square-foot house, the heat pump draws about 6,846 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,143 a year. Buffalo's gas rate of 10.98 per Mcf, applied to the 70 Mcf a year the furnace burns, puts its running cost near $870 a year, against 15.67¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $7,591 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Buffalo — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Buffalo's answer improves. About $1,613 a year comes back this way, enough that the 5-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Buffalo ranks in this dataset
Among 3206 cities, Buffalo's winter puts it at rank 69 for severity, while its size puts it at rank 2221 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.
What to do with this number in Buffalo
Buffalo, Minnesota is home to about 16,736 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Buffalo, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page — the 2.47 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Buffalo's -9.4°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.
