Heat Pump Payback in Union, MO
Will a heat pump pay off in Union, MO?
In Union, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Union would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $221 saved annually, for a payback of roughly 24.8 years. Union's own numbers say this pencils out only in theory, not in practice.

The climate behind Union's payback figure
Degree days tell the story here: Union racks up 3754 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1476 cooling degree days on the cooling side. 1.4°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -7.6°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.73 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Union, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Washington Regional Airport, the closest NOAA station, 10 miles out.
The yearly running costs in Union
A 2000-square-foot house here would pull roughly 3,482 heating kilowatt-hours annually on top of cooling, totalling about $608 a year on electricity. The gas furnace it replaces burns roughly 39 Mcf a year at $14.94 per Mcf here, for a running cost near $830 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 $2,180 behind.
How sensitive Union's result is to prices
This result holds unless electricity climbs above 20.7¢/kWh (it is 12.83¢ now) or gas drops below $9.28 per Mcf (now $14.94); past either point, gas becomes the cheaper fuel in Union. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $221 a year saved, a difference under $1,547 pays back within 7 years here, and under $2,210 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Union 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. About $857 a year comes back this way, enough that the 11.7-year payback clears the $10,000 premium comfortably within the equipment's life.
How Union compares nationally
Ranked against the other 3206 cities covered, Union comes in at 1647 for heating severity, 1 would be the coldest place in the dataset, and 2627 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Where Union's figure comes from
Every constant behind this page, the 2.73 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Union's 1.4°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.
