Heat pump vs. gas furnace in Grand Forks, ND
In Grand Forks, 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). Unfortunately the electric bill outweighs the gas bill it replaces by about $174 a year here, so the extra spend stays unrecovered. That's Grand Forks's own climate and rates talking, not a hedge or a caveat.
Grand Forks's weather, in the numbers that matter
7753 heating degree days pile up here every year, so Grand Forks has one of the harshest winters in the country; the cooling side runs to 566 cooling degree days, where summers add a moderate cooling load. -11.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -15°F on file. Worked through the model, that's a seasonal COP of 2.41 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Grand Forks — 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 Grand Forks
A 2000-square-foot house here would pull roughly 8,146 heating kilowatt-hours annually on top of cooling, totalling about $1,029 a year on electricity. That compares with roughly 81 Mcf a year of gas at Grand Forks's 9.50 per-Mcf rate — about $855 a year — against a local electricity rate of 11.92¢/kWh. 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 $6,110 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Grand Forks — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Grand Forks's answer improves. Switching saves about $1,399 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 5.7 years.
Grand Forks against the rest of the country
Among 3206 cities, Grand Forks's winter puts it at rank 15 for severity, while its size puts it at rank 674 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.
Next step for 59,845 people in Grand Forks
Grand Forks, North Dakota is home to about 59,845 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 Grand Forks, nothing is lost by holding off until the current equipment genuinely fails.

The methodology guide walks through exactly how Grand Forks's 2.41 seasonal COP and the rest of this page's numbers get built. Grand Forks's -11.9°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.
