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 $3,500 more up front here (already netting out a $2,000 tax credit). 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, against a record low of -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 ARPT, 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 — against a local electricity rate of 19.06¢/kWh. 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 $6,505 behind.
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 $8,000 spent up front comes back in about 5.7 years.
Where Quincy ranks in this dataset
Quincy lands at position 1235 out of 3206 cities on heating severity (coldest is 1), and 1061 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
Next step for 38,786 people in Quincy
Quincy, Illinois is home to about 38,786 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Quincy, nothing is lost by holding off until the current equipment genuinely fails.
