Heat pump vs. gas furnace in Bensenville, IL
In Bensenville, a heat pump would cost more to run each year than what you have now. $3,500 is what Bensenville 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. The heat pump would cost about $240 more a year to run than the furnace it replaces — a premium with no payback. That's Bensenville's own climate and rates talking, not a hedge or a caveat.
Bensenville's weather, in the numbers that matter
4837 heating degree days pile up here every year, so Bensenville has a real but manageable winter; the cooling side runs to 1162 cooling degree days, where summers are hot enough that cooling matters as much as heating. -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. Bensenville 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.

What it actually costs to run, year to year
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. Bensenville'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. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $7,099 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Bensenville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Bensenville's answer improves. The saving here runs about $1,528 a year, which recovers the extra $8,000 spent going electric in roughly 5.2 years.
How Bensenville compares nationally
Bensenville lands at position 920 out of 3206 cities on heating severity (coldest is 1), and 2041 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.
