Heat Pump Payback in Madison, IN
Is a heat pump worth it in Madison?
Madison is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Madison 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 $11 a year here, so the extra spend stays unrecovered. That's Madison's own climate and rates talking, not a hedge or a caveat.

How cold Madison actually gets
3632 heating degree days pile up here every year, so Madison has a real but manageable winter; the cooling side runs to 1460 cooling degree days, where summers are hot enough that cooling matters as much as heating. 5°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 1.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.82 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Madison sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in Madison
A 2000-square-foot house here would pull roughly 3,261 heating kilowatt-hours annually on top of cooling, totalling about $767 a year on electricity. The gas furnace it replaces burns roughly 38 Mcf a year at $11.49 per Mcf here, for a running cost near $757 a year including the old AC (electricity here runs 17.03¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $5,658 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Madison's answer
For the verdict in Madison to flip, electricity would need to drop to about 16.6¢/kWh from 17.03¢, or gas climb past $11.77 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 Madison; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Madison, compared
Not every home in Madison has gas service. 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 $1,121 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 8.9 years.
Madison against the rest of the country
Among 3206 cities, Madison's winter puts it at rank 1729 for severity, while its size puts it at rank 2797 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 Madison
Madison, Indiana is home to about 12,108 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 Madison, nothing is lost by holding off until the current equipment genuinely fails.
