Lincoln, IL: the heat pump payback math
Lincoln is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Lincoln 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 $194 more a year to run than the furnace it replaces — a premium with no payback. That's Lincoln's own climate and rates talking, not a hedge or a caveat.
Lincoln's weather, in the numbers that matter
Degree days tell the story here: Lincoln racks up 4494 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1192 cooling degree days on the cooling side. -2.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -11.7°F on file. Worked through the model, that's a seasonal COP of 2.64 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Lincoln — 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 LOGAN COUNTY AIRPORT, the closest NOAA station, 1.9 miles out.
The month-to-month numbers for Lincoln
Electricity use for heating alone comes out to about 4,310 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,015 a year. The gas furnace it replaces burns roughly 47 Mcf a year at 11.25 per Mcf here, for a running cost near $821 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 $6,414 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Lincoln — 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. Switching saves about $1,448 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 5.5 years.
Where Lincoln ranks in this dataset
Lincoln lands at position 1199 out of 3206 cities on heating severity (coldest is 1), and 2647 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Lincoln
Lincoln, Illinois is home to about 13,047 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 Lincoln, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
