Heat Pump Payback in Bellefontaine Neighbors, MO
Will a heat pump pay off in Bellefontaine Neighbors, MO?
Bellefontaine Neighbors technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Bellefontaine Neighbors's residents would see roughly $242 a year back in running costs, putting the payback around 22.8 years. That's a technicality, not a recommendation, for anyone actually living in Bellefontaine Neighbors.

Bellefontaine Neighbors's weather, in the numbers that matter
Bellefontaine Neighbors has a real but manageable winter, 3396 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2013 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 1.9°F, and the coldest daily reading in the 2024 station record was -7.1°F. That puts the seasonal coefficient of performance at 2.75 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Bellefontaine Neighbors sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 3,127 heating kilowatt-hours annually on top of cooling, totalling about $621 a year on electricity. The gas furnace it replaces burns roughly 35 Mcf a year at $14.94 per Mcf here, for a running cost near $863 a year including the old AC (electricity here runs 12.83¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,874 behind.
What would change Bellefontaine Neighbors's answer
Gas would only overtake the heat pump in Bellefontaine Neighbors if electricity rose past 23.6¢/kWh from 12.83¢, or gas fell under $8.11 per Mcf from $14.94. A useful quote test for Bellefontaine Neighbors: the heat pump is worth it within a decade if it costs less than $2,420 more than replacing the furnace and AC, and within 7 years if the gap is under $1,694.
The other scenario: no gas furnace to begin with
Not every home in Bellefontaine Neighbors has gas service. Swap the comparison to resistance heat instead of gas, and Bellefontaine Neighbors's answer improves. About $817 a year comes back this way, enough that the 12.2-year payback clears the $10,000 premium comfortably within the equipment's life.
