Heat Pump Payback in Gary, IN
Is a heat pump worth it in Gary?
Here in Gary, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Gary would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $120 a year here, so the extra spend stays unrecovered. That's Gary's own climate and rates talking, not a hedge or a caveat.

How cold Gary actually gets
Degree days tell the story here: Gary racks up 4836 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1011 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: -0.4°F here (coldest 2024 reading -9.4°F), which works out to a seasonal COP of 2.69 for the cold-climate class of unit this climate calls for. Gary needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,552 kWh a year to keep it warm, plus cooling, for a combined electric bill near $922 a year. That compares with roughly 50 Mcf a year of gas at Gary's $11.49 per-Mcf rate, about $802 a year with the old AC included, against a local electricity rate of 17.03¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $7,303 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Gary's answer
For the verdict in Gary to flip, electricity would need to drop to about 14.1¢/kWh from 17.03¢, or gas climb past $13.88 per Mcf from $11.49. 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 Gary; the case for one here rests on comfort, cooling, or replacing electric heat instead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Gary, 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. About $1,386 a year comes back this way, enough that the 7.2-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Gary ranks in this dataset
Gary lands at position 932 out of 3206 cities on heating severity (coldest is 1), and 577 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
