Heat Pump Payback in Andover, MN
Is a heat pump worth it in Andover?
Here in Andover, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Unfortunately the electric bill outweighs the gas bill it replaces by about $206 a year here, so the extra spend stays unrecovered. That's Andover's own climate and rates talking, not a hedge or a caveat.

How cold Andover actually gets
Andover has a cold winter that leans hard on heating equipment, 6039 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 779 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -7.6°F, and the coldest daily reading in the 2024 station record was -7.6°F. That puts the seasonal coefficient of performance at 2.52 for the recommended cold-climate unit. A cold-climate unit is the right call in Andover, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, Anoka Co-Blne Ap(Jns Fd) AP, 9.2 miles from Andover.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 6,068 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,055 a year. The gas furnace it replaces burns roughly 63 Mcf a year at $10.98 per Mcf here, for a running cost near $849 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: $8,593 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Andover's answer
For the verdict in Andover to flip, electricity would need to drop to about 12.1¢/kWh from 15.67¢, or gas climb past $14.26 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 Andover; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Andover, compared
Plenty of homes in Andover heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,499 a year, which recovers the extra $10,000 spent going electric in roughly 6.7 years.
How Andover compares nationally
Andover lands at position 204 out of 3206 cities on heating severity (coldest is 1), and 1232 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.

Where Andover's figure comes from
The methodology guide walks through exactly how Andover's 2.52 seasonal COP and the rest of this page's numbers get built. Andover's -7.6°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.
