Pingree Grove, IL: the heat pump payback math
Pingree Grove 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). Unfortunately the electric bill outweighs the gas bill it replaces by about $295 a year here, so the extra spend stays unrecovered. There's no spin on that: Pingree Grove's numbers say wait.
Why Pingree Grove's climate drives this number
5064 heating degree days pile up here every year, so Pingree Grove has a cold winter that leans hard on heating equipment; the cooling side runs to 915 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -7.1°F here (record low -14.1°F), which works out to a seasonal COP of 2.53 for the cold-climate class of unit this climate calls for. Pingree Grove 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. These numbers come from DUPAGE AIRPORT, the closest NOAA station, 15.3 miles out.
Pingree Grove's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 5,068 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,115 a year. That compares with roughly 53 Mcf a year of gas at Pingree Grove's 11.25 per-Mcf rate — about $819 a year — against a local electricity rate of 19.06¢/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 $7,930 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Pingree Grove heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Pingree Grove's answer improves. About $1,555 a year comes back this way, enough that the 5.1-year payback clears the $8,000 premium comfortably within the equipment's life.
How Pingree Grove compares nationally
Pingree Grove lands at position 642 out of 3206 cities on heating severity (coldest is 1), and 2896 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 Pingree Grove
About 11,512 people live in Pingree Grove, Illinois, 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.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Pingree Grove's 2.53 seasonal COP and payback figure. At a -7.1°F design temperature, Pingree Grove sits in cold-climate territory; the guide to that class of unit explains why.
