Why Brown Deer's climate drives this number
Brown Deer has a cold winter that leans hard on heating equipment, 5878 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 552 cooling degree days. -2.2°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -9.4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.65 on the cold-climate unit fit for this climate. Brown Deer 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.

Brown Deer's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,617 heating kilowatt-hours annually on top of cooling, totalling about $1,149 a year on electricity. The gas furnace it replaces burns roughly 61 Mcf a year at $10.74 per Mcf here, for a running cost near $792 a year including the old AC (electricity here runs 18.87¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $10,843 behind.
What would change Brown Deer's answer
The heat pump would become the cheaper option in Brown Deer if electricity fell to 12.2¢/kWh (from 18.87¢) or gas rose above $16.56 per Mcf (from $10.74). At today's prices a cheaper quote cannot rescue the gas comparison in Brown Deer, since there is no yearly saving to recover it from.
Electric resistance heat in Brown Deer, compared
Not every home in Brown Deer has gas service. Swap the comparison to resistance heat instead of gas, and Brown Deer's answer improves. About $1,795 a year comes back this way, enough that the 5.6-year payback clears the $10,000 premium comfortably within the equipment's life.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Brown Deer's 2.65 seasonal COP and payback figure. Brown Deer's -2.2°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.
