Is a heat pump worth it in Wood Dale?
Wood Dale is a place where a heat pump genuinely costs more to operate than the alternative. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). The heat pump would cost about $240 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Wood Dale's numbers say wait.
The climate behind Wood Dale's payback figure
Wood Dale has a real but manageable winter — 4837 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1162 cooling degree days. -5.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -9.9°F on file. Worked through the model, that's a seasonal COP of 2.58 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Wood Dale sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, CHICAGO O'HARE INTERNATIONAL, 2.6 miles from Wood Dale.
Wood Dale's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,747 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,094 a year. Wood Dale's gas rate of 11.25 per Mcf, applied to the 50 Mcf a year the furnace burns, puts its running cost near $854 a year, against 19.06¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,099 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Wood Dale heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Wood Dale's answer improves. Switching saves about $1,528 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 5.2 years.
Wood Dale against the rest of the country
Among 3206 cities, Wood Dale's winter puts it at rank 925 for severity, while its size puts it at rank 2513 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Wood Dale's figure comes from
Every constant behind this page — the 2.58 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Wood Dale's -5.1°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.
