Heat Pump Payback in Danville, IN
Should Danville switch to a heat pump?
In Danville, a heat pump would cost more to run each year than what you have now. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Running costs here land $59 a year higher than the furnace it replaces, so that premium is never recovered. That's Danville's own climate and rates talking, not a hedge or a caveat.

How cold Danville actually gets
Degree days tell the story here: Danville racks up 4073 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1379 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 0°F, and the coldest daily reading in the 2024 station record was -4°F. That puts the seasonal coefficient of performance at 2.7 for the recommended cold-climate unit. Danville 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
A 2000-square-foot house here would pull roughly 3,820 heating kilowatt-hours annually on top of cooling, totalling about $851 a year on electricity. Danville's gas rate of $11.49 per Mcf, applied to the 42 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $792 a year, against 17.03¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $6,385 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Danville's answer
For the verdict in Danville to flip, electricity would need to drop to about 15.2¢/kWh from 17.03¢, or gas climb past $12.88 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 Danville; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Danville, 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 $1,210 a year comes back this way, enough that the 8.3-year payback clears the $10,000 premium comfortably within the equipment's life.
Danville against the rest of the country
Ranked against the other 3206 cities covered, Danville comes in at 1478 for heating severity, 1 would be the coldest place in the dataset, and 2725 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
What to do with this number in Danville
Danville, Indiana is home to about 12,532 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 Danville, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
