Heat Pump Payback in Lawrence, IN
Lawrence, IN: the heat pump payback math
Here in Lawrence, 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. The heat pump would cost about $59 more a year to run than the furnace it replaces, a premium with no payback. That's Lawrence's own climate and rates talking, not a hedge or a caveat.

How cold Lawrence actually gets
Degree days tell the story here: Lawrence 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. 0°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.7 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Lawrence sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Eagle Creek Airpark Airport, 16.5 miles from Lawrence.
The yearly running costs in Lawrence
Electricity use for heating alone comes out to about 3,820 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $851 a year. The gas furnace it replaces burns roughly 42 Mcf a year at $11.49 per Mcf here, for a running cost near $792 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: $6,385 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Lawrence's result is to prices
For the verdict in Lawrence 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 Lawrence; 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 Lawrence heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Lawrence's answer improves. Switching saves about $1,210 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 8.3 years.
Lawrence against the rest of the country
Lawrence lands at position 1475 out of 3206 cities on heating severity (coldest is 1), and 823 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
