Heat Pump Payback in Brownsburg, IN
Is a heat pump worth it in Brownsburg?
In Brownsburg, a heat pump would cost more to run each year than what you have now. $5,500 is what Brownsburg 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 $59 a year here, so the extra spend stays unrecovered. That's Brownsburg's own climate and rates talking, not a hedge or a caveat.

Brownsburg's weather, in the numbers that matter
Degree days tell the story here: Brownsburg 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. Brownsburg 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. Climate figures trace to the nearest NOAA station, Eagle Creek Airpark Airport, 4.8 miles from Brownsburg.
The yearly running costs in Brownsburg
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. Brownsburg'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.
The break-even point in Brownsburg
For the verdict in Brownsburg 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 Brownsburg; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Brownsburg 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 $1,210 a year comes back this way, enough that the 8.3-year payback clears the $10,000 premium comfortably within the equipment's life.
How Brownsburg compares nationally
Among 3206 cities, Brownsburg's winter puts it at rank 1476 for severity, while its size puts it at rank 1231 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
