Heat Pump Payback in Lawrence, KS
Lawrence, KS: the heat pump payback math
Lawrence technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lawrence's residents would see roughly $109 a year back in running costs, putting the payback around 50.4 years. Lawrence's own numbers say this pencils out only in theory, not in practice.

Why Lawrence's climate drives this number
Lawrence has a real but manageable winter, 4292 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1479 cooling degree days. -8°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -13°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.51 on the cold-climate unit fit for this climate. Lawrence 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.

Lawrence's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,330 heating kilowatt-hours annually on top of cooling, totalling about $841 a year on electricity. Lawrence's gas rate of $14.81 per Mcf, applied to the 45 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $950 a year, against 15.05¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $3,864 behind.
The break-even point in Lawrence
This result holds unless electricity climbs above 18.0¢/kWh (it is 15.05¢ now) or gas drops below $12.37 per Mcf (now $14.81); past either point, gas becomes the cheaper fuel in Lawrence. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $109 a year saved, a difference under $763 pays back within 7 years here, and under $1,090 within 10.
If your home heats with electric baseboard instead of gas
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. The saving here runs about $1,083 a year, which recovers the extra $10,000 spent going electric in roughly 9.2 years.
Where Lawrence ranks in this dataset
Lawrence lands at position 1327 out of 3206 cities on heating severity (coldest is 1), and 352 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 Lawrence
About 97,271 people live in Lawrence, Kansas, and every number on this page is what a contractor would actually work from when quoting a system here, the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
