Heat Pump Payback in Alexandria, MN
Heat pump vs. gas furnace in Alexandria, MN
In Alexandria, 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 $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $331 a year here, so the extra spend stays unrecovered. That's Alexandria's own climate and rates talking, not a hedge or a caveat.

Alexandria's weather, in the numbers that matter
7234 heating degree days pile up here every year, so Alexandria has one of the harshest winters in the country; the cooling side runs to 474 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 low of -17°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.41 on the cold-climate unit fit for this climate. Alexandria 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.

Alexandria's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 7,601 heating kilowatt-hours annually on top of cooling, totalling about $1,254 a year on electricity. The gas furnace it replaces burns roughly 75 Mcf a year at $10.98 per Mcf here, for a running cost near $923 a year including the old AC (electricity here runs 15.67¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $10,463 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Alexandria's answer
For the verdict in Alexandria to flip, electricity would need to drop to about 11.2¢/kWh from 15.67¢, or gas climb past $15.37 per Mcf from $10.98. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Alexandria; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Alexandria, compared
Gas isn't universal in Alexandria, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,712 a year, which recovers the extra $10,000 spent going electric in roughly 5.8 years.
Where Alexandria ranks in this dataset
Ranked against the other 3206 cities covered, Alexandria comes in at 38 for heating severity, 1 would be the coldest place in the dataset, and 2401 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
Deciding what's next in Alexandria, MN
Alexandria, Minnesota is home to about 14,914 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 Alexandria, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
