Will a heat pump pay off in Hammond, IN?
Here in Hammond, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Unfortunately the electric bill outweighs the gas bill it replaces by about $120 a year here, so the extra spend stays unrecovered. There's no spin on that: Hammond's numbers say wait.
Why Hammond's climate drives this number
4836 heating degree days pile up here every year, so Hammond has a real but manageable winter; the cooling side runs to 1011 cooling degree days, where summers are hot enough that cooling matters as much as heating. -0.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -9.4°F on file. Worked through the model, that's a seasonal COP of 2.69 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Hammond — 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 GARY/CHICAGO AIRPORT, the closest NOAA station, 4 miles out.
Hammond's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,552 heating kilowatt-hours annually on top of cooling, totalling about $922 a year on electricity. That compares with roughly 50 Mcf a year of gas at Hammond's 11.49 per-Mcf rate — about $802 a year — against a local electricity rate of 17.03¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $5,303 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Hammond heat with electricity alone, no gas line involved. 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 5.8-year payback clears the $8,000 premium comfortably within the equipment's life.
How Hammond compares nationally
Ranked against the other 3206 cities covered, Hammond comes in at 931 for heating severity — 1 would be the coldest place in the dataset — and 499 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
