Heat Pump Payback in Alsip, IL
Will a heat pump pay off in Alsip, IL?
Here in Alsip, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Running costs here land $151 a year higher than the furnace it replaces, so that premium is never recovered. That's Alsip's own climate and rates talking, not a hedge or a caveat.

Alsip's weather, in the numbers that matter
Degree days tell the story here: Alsip racks up 4543 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1348 cooling degree days on the cooling side. 1.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.75 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Alsip sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,183 heating kilowatt-hours annually on top of cooling, totalling about $1,016 a year on electricity. The gas furnace it replaces burns roughly 47 Mcf a year at $11.25 per Mcf here, for a running cost near $865 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: $7,767 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Alsip's answer
For the verdict in Alsip to flip, electricity would need to drop to about 14.8¢/kWh from 19.06¢, or gas climb past $14.44 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 Alsip; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Alsip heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Alsip's answer improves. The saving here runs about $1,509 a year, which recovers the extra $10,000 spent going electric in roughly 6.6 years.
How Alsip compares nationally
