Heat Pump Payback in Cambridge, OH
Cambridge, OH: the heat pump payback math
In Cambridge, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Cambridge's residents would see roughly $21 a year back in running costs, putting the payback around 259.6 years. Cambridge's own numbers say this pencils out only in theory, not in practice.

The climate behind Cambridge's payback figure
4289 heating degree days pile up here every year, so Cambridge has a real but manageable winter; the cooling side runs to 1152 cooling degree days, where summers are hot enough that cooling matters as much as heating. 8.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 5°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.89 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Cambridge sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,758 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $872 a year. That compares with roughly 45 Mcf a year of gas at Cambridge's $13.85 per-Mcf rate, about $893 a year with the old AC included, against a local electricity rate of 18.40¢/kWh. 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 $5,182 behind.
The break-even point in Cambridge
This result holds unless electricity climbs above 19.1¢/kWh (it is 18.40¢ now) or gas drops below $13.38 per Mcf (now $13.85); past either point, gas becomes the cheaper fuel in Cambridge. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $21 a year saved, a difference under $147 pays back within 7 years here, and under $210 within 10.
If your home heats with electric baseboard instead of gas
Not every home in Cambridge has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,401 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 7.1 years.
How Cambridge compares nationally
Ranked against the other 3206 cities covered, Cambridge comes in at 1332 for heating severity, 1 would be the coldest place in the dataset, and 3198 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Where Cambridge's figure comes from
Every constant behind this page, the 2.89 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Cambridge's 8.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
