Is a heat pump worth it in River Grove?
River Grove is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what River Grove 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 $240 a year here, so the extra spend stays unrecovered. There's no spin on that: River Grove's numbers say wait.
The climate behind River Grove's payback figure
Degree days tell the story here: River Grove racks up 4837 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1162 cooling degree days on the cooling side. -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. River 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 CHICAGO O'HARE INTERNATIONAL, the closest NOAA station, 5.4 miles out.
The month-to-month numbers for River Grove
Electricity use for heating alone comes out to about 4,747 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,094 a year. The gas furnace it replaces burns roughly 50 Mcf a year at 11.25 per Mcf here, for a running cost near $854 a year (electricity here runs 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 $7,099 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in River Grove — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,528 a year comes back this way, enough that the 5.2-year payback clears the $8,000 premium comfortably within the equipment's life.
River Grove against the rest of the country
Ranked against the other 3206 cities covered, River Grove comes in at 930 for heating severity — 1 would be the coldest place in the dataset — and 3102 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where River Grove's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind River Grove's 2.58 seasonal COP and payback figure. River Grove's -5.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
