Heat Pump Payback in Dixon, IL
Heat pump vs. gas furnace in Dixon, IL
Here in Dixon, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Running costs here land $414 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Dixon's numbers say wait.

The climate behind Dixon's payback figure
Dixon has a cold winter that leans hard on heating equipment, 5573 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 690 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -12.8°F, and the coldest daily reading in the 2024 station record was -17.5°F. That puts the seasonal coefficient of performance at 2.39 for the recommended cold-climate unit. Dixon 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.

The yearly running costs in Dixon
Modelled on a typical 2000-square-foot house, the heat pump draws about 5,904 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,238 a year. Dixon's gas rate of $11.25 per Mcf, applied to the 58 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $823 a year, against 19.06¢ per kWh for electricity. With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $11,712 behind.
The break-even point in Dixon
The heat pump would become the cheaper option in Dixon if electricity fell to 11.7¢/kWh (from 19.06¢) or gas rose above $18.38 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Dixon, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Plenty of homes in Dixon heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,623 a year, which recovers the extra $10,000 spent going electric in roughly 6.2 years.
Where Dixon ranks in this dataset
Among 3206 cities, Dixon's winter puts it at rank 346 for severity, while its size puts it at rank 2374 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.
