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 $3,500 after a $2,000 federal tax credit. 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 record low of -9°F on file. 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 (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 $5,767 behind.

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 $8,000 spent going electric in roughly 5.3 years.

How Alsip compares nationally

Among 3206 cities, Alsip's winter puts it at rank 1157 for severity, while its size puts it at rank 2055 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 Alsip

Alsip, Illinois is home to about 18,486 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 Alsip, nothing is lost by holding off until the current equipment genuinely fails.
