Heat Pump Payback in Webb City, MO
Webb City, MO: the heat pump payback math
In Webb City, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Webb City would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $232 of lower running costs every year, landing the payback clock at roughly 23.7 years. That's a technicality, not a recommendation, for anyone actually living in Webb City.

Webb City's weather, in the numbers that matter
3249 heating degree days pile up here every year, so Webb City has a real but manageable winter; the cooling side runs to 1898 cooling degree days, where summers are hot enough that cooling matters as much as heating. 3°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -7.1°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.77 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Webb City, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 2,970 heating kilowatt-hours annually on top of cooling, totalling about $589 a year on electricity. Webb City's gas rate of $14.94 per Mcf, applied to the 34 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $821 a year, against 12.83¢ per kWh for electricity. 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 $2,013 behind.
What would change Webb City's answer
Gas would only overtake the heat pump in Webb City if electricity rose past 23.8¢/kWh from 12.83¢, or gas fell under $8.07 per Mcf from $14.94. A useful quote test for Webb City: the heat pump is worth it within a decade if it costs less than $2,320 more than replacing the furnace and AC, and within 7 years if the gap is under $1,624.
The other scenario: no gas furnace to begin with
Not every home in Webb City has gas service. 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 $782 a year, which recovers the extra $10,000 spent going electric in roughly 12.8 years.
Webb City against the rest of the country
Ranked against the other 3206 cities covered, Webb City comes in at 1836 for heating severity, 1 would be the coldest place in the dataset, and 2602 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
