Will a heat pump pay off in Indianola, IA?
Here in Indianola, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Indianola would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Running costs here land $70 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Indianola's numbers say wait.
Why Indianola's climate drives this number
Degree days tell the story here: Indianola racks up 4972 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1291 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -11.9°F, against a record low of -17°F. That puts the seasonal coefficient of performance at 2.41 for the recommended cold-climate unit. Indianola 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. Climate figures trace to the nearest NOAA station, DES MOINES INTERNATIONAL AIRP, 12.7 miles from Indianola.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 5,224 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $842 a year. That compares with roughly 52 Mcf a year of gas at Indianola's 10.61 per-Mcf rate — about $772 a year — against a local electricity rate of 13.31¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $4,546 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Indianola 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 $1,057 a year, which recovers the extra $8,000 spent going electric in roughly 7.6 years.
Indianola against the rest of the country
Indianola lands at position 746 out of 3206 cities on heating severity (coldest is 1), and 2268 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.

About 16,297 people live in Indianola, Iowa, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Where Indianola's figure comes from
Every constant behind this page — the 2.41 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Indianola's -11.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
