Heat Pump Payback in Morton, IL
Morton, IL: the heat pump payback math
Morton is a place where a heat pump genuinely costs more to operate than the alternative. 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 $209 more a year to run than the furnace it replaces, a premium with no payback. That's Morton's own climate and rates talking, not a hedge or a caveat.

How cold Morton actually gets
4554 heating degree days pile up here every year, so Morton has a real but manageable winter; the cooling side runs to 1292 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 low of -13°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.58 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Morton sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Greater Peoria Regional Airpo, 12 miles from Morton.
The yearly running costs in Morton
Electricity use for heating alone comes out to about 4,470 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,062 a year. The gas furnace it replaces burns roughly 47 Mcf a year at $11.25 per Mcf here, for a running cost near $853 a year including the old AC (electricity here runs 19.06¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $8,637 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Morton
For the verdict in Morton to flip, electricity would need to drop to about 13.7¢/kWh from 19.06¢, or gas climb past $15.66 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 Morton; the case for one here rests on comfort, cooling, or replacing electric heat instead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Morton heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Morton's answer improves. Switching saves about $1,455 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 6.9 years.
Where Morton ranks in this dataset
Among 3206 cities, Morton's winter puts it at rank 1130 for severity, while its size puts it at rank 2133 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Morton
Morton, Illinois is home to about 17,557 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 Morton, nothing is lost by holding off until the current equipment genuinely fails.

Where Morton's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Morton's 2.58 seasonal COP and payback figure. Morton's -5.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
