Heat Pump Payback in Quincy, IL
Will a heat pump pay off in Quincy, IL?
In Quincy, a heat pump would cost more to run each year than what you have now. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. The heat pump would cost about $200 more a year to run than the furnace it replaces, a premium with no payback. That's Quincy's own climate and rates talking, not a hedge or a caveat.

Quincy's weather, in the numbers that matter
4368 heating degree days pile up here every year, so Quincy has a real but manageable winter; the cooling side runs to 1318 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -6°F, and the coldest daily reading in the 2024 station record was -14.1°F. That puts the seasonal coefficient of performance at 2.56 for the recommended cold-climate unit. A cold-climate unit is the right call in Quincy, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Quincy Rgnl-Bldwn Fld Airport, the closest NOAA station, 9.9 miles out.
Quincy's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,320 heating kilowatt-hours annually on top of cooling, totalling about $1,038 a year on electricity. That compares with roughly 45 Mcf a year of gas at Quincy's $11.25 per-Mcf rate, about $837 a year with the old AC included, against a local electricity rate of 19.06¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $8,505 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Quincy
For the verdict in Quincy to flip, electricity would need to drop to about 13.7¢/kWh from 19.06¢, or gas climb past $15.65 per Mcf from $11.25. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Quincy; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Quincy, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,396 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 7.2 years.
Where Quincy ranks in this dataset
