Heat Pump Payback in Randolph Town, MA
Heat pump vs. gas furnace in Randolph Town, MA
The payback math works in Randolph Town on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. That premium is recovered through $134 of lower running costs every year, landing the payback clock at roughly 41.1 years. Randolph Town's own numbers say this pencils out only in theory, not in practice.

Why Randolph Town's climate drives this number
4997 heating degree days pile up here every year, so Randolph Town has a real but manageable winter; the cooling side runs to 885 cooling degree days, where summers add a moderate cooling load. 10.9°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 2.96 on the cold-climate unit fit for this climate. Randolph Town 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.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 4,275 heating kilowatt-hours annually on top of cooling, totalling about $1,516 a year on electricity. That compares with roughly 52 Mcf a year of gas at Randolph Town's $25.06 per-Mcf rate, about $1,650 a year with the old AC included, against a local electricity rate of 30.15¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $3,495 behind.
The break-even point in Randolph Town
This result holds unless electricity climbs above 33.6¢/kWh (it is 30.15¢ now) or gas drops below $22.49 per Mcf (now $25.06); past either point, gas becomes the cheaper fuel in Randolph Town. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $134 a year saved, a difference under $938 pays back within 7 years here, and under $1,340 within 10.
Electric resistance heat in Randolph Town, compared
Gas isn't universal in Randolph Town, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $2,644 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 3.8 years.
Where Randolph Town ranks in this dataset

More on how this number was built
The methodology guide walks through exactly how Randolph Town's 2.96 seasonal COP and the rest of this page's numbers get built. Randolph Town's 10.9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
