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 $3,500 more up front here (already netting out a $2,000 tax credit). Cambridge's residents would see roughly $21 a year back in running costs, putting the payback around 165.2 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 record low of 5°F on file. 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 — against a local electricity rate of 18.40¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 637.2 years, leaving the 15-year total $3,182 behind.
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 $8,000 spent up front comes back in about 5.7 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.

About 10,036 people live in Cambridge, Ohio, 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.

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.
