Heat pump vs. gas furnace in Elkhart, IN
Here in Elkhart, 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). The heat pump would cost about $153 more a year to run than the furnace it replaces — a premium with no payback. That's Elkhart's own climate and rates talking, not a hedge or a caveat.
How cold Elkhart actually gets
Degree days tell the story here: Elkhart racks up 4968 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 773 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: -1.7°F here (record low -10.8°F), which works out to a seasonal COP of 2.66 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Elkhart — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Elkhart's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,729 kWh a year to keep it warm, plus cooling, for a combined electric bill near $918 a year. Elkhart's gas rate of 11.49 per Mcf, applied to the 52 Mcf a year the furnace burns, puts its running cost near $765 a year, against 17.03¢ per kWh for electricity. 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 $5,788 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Elkhart — 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. Switching saves about $1,395 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 5.7 years.
How Elkhart compares nationally
Ranked against the other 3206 cities covered, Elkhart comes in at 790 for heating severity — 1 would be the coldest place in the dataset — and 756 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Elkhart
Elkhart, Indiana is home to about 53,690 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 Elkhart, nothing is lost by holding off until the current equipment genuinely fails.

Where Elkhart's figure comes from
Every constant behind this page — the 2.66 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Elkhart's -1.7°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
