Heat Pump Payback in Mooresville, IN
Heat pump vs. gas furnace in Mooresville, IN
Here in Mooresville, 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 $5,500 more up front here. Running costs here land $80 a year higher than the furnace it replaces, so that premium is never recovered. That's Mooresville's own climate and rates talking, not a hedge or a caveat.

How cold Mooresville actually gets
4285 heating degree days pile up here every year, so Mooresville has a real but manageable winter; the cooling side runs to 1278 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is -0.9°F, and the coldest daily reading in the 2024 station record was -6°F. That puts the seasonal coefficient of performance at 2.68 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Mooresville sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from Indianapolis International Ai, the closest NOAA station, 9.6 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,049 heating kilowatt-hours annually on top of cooling, totalling about $875 a year on electricity. Mooresville's gas rate of $11.49 per Mcf, applied to the 45 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $795 a year, against 17.03¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $6,703 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Mooresville's answer
For the verdict in Mooresville to flip, electricity would need to drop to about 14.7¢/kWh from 17.03¢, or gas climb past $13.29 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 Mooresville; 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 Mooresville, 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 $1,255 a year comes back this way, enough that the 8-year payback clears the $10,000 premium comfortably within the equipment's life.
Mooresville against the rest of the country
Mooresville lands at position 1350 out of 3206 cities on heating severity (coldest is 1), and 3202 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Mooresville
Mooresville, Indiana is home to about 10,027 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 Mooresville, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
More on how this number was built
The methodology guide walks through exactly how Mooresville's 2.68 seasonal COP and the rest of this page's numbers get built. Mooresville's -0.9°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.
