Is a heat pump worth it in Urbandale?

In Urbandale, a heat pump would cost more to run each year than what you have now. $3,500 is what Urbandale 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. Unfortunately the electric bill outweighs the gas bill it replaces by about $70 a year here, so the extra spend stays unrecovered. That's Urbandale's own climate and rates talking, not a hedge or a caveat.

How cold Urbandale actually gets

Degree days tell the story here: Urbandale 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. Below the 25°F line where a standard machine starts leaning on resistance backup, Urbandale sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from DES MOINES INTERNATIONAL AIRP, the closest NOAA station, 9.7 miles out.

The month-to-month numbers for Urbandale

Modelled on a typical 2000-square-foot house, the heat pump draws about 5,224 kWh a year to keep it warm, plus cooling, for a combined electric bill near $842 a year. The gas furnace it replaces burns roughly 52 Mcf a year at 10.61 per Mcf here, for a running cost near $772 a year (electricity here runs 13.31¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $4,546 behind.

If your home heats with electric baseboard instead of gas

Gas isn't universal in Urbandale — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,057 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 7.6 years.

Urbandale against the rest of the country

Urbandale lands at position 743 out of 3206 cities on heating severity (coldest is 1), and 859 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.

What to do with this number in Urbandale

Urbandale, Iowa is home to about 47,759 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Urbandale, nothing is lost by holding off until the current equipment genuinely fails.

Where Urbandale's figure comes from

The methodology guide walks through exactly how Urbandale's 2.41 seasonal COP and the rest of this page's numbers get built. At a -11.9°F design temperature, Urbandale sits in cold-climate territory; the guide to that class of unit explains why.
