Heat Pump Payback in Franklin Town, MA
Is a heat pump worth it in Franklin Town?
Franklin Town technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Franklin Town would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $84 saved annually, for a payback of roughly 65.6 years. That's a technicality, not a recommendation, for anyone actually living in Franklin Town.

Franklin Town's weather, in the numbers that matter
5467 heating degree days pile up here every year, so Franklin Town has a cold winter that leans hard on heating equipment; the cooling side runs to 573 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 10°F, and the coldest daily reading in the 2024 station record was 3°F. That puts the seasonal coefficient of performance at 2.94 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Franklin Town sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from North Central State Airport, the closest NOAA station, 12.1 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,709 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,567 a year. That compares with roughly 57 Mcf a year of gas at Franklin Town's $25.06 per-Mcf rate, about $1,651 a year with the old AC included, against a local electricity rate of 30.15¢/kWh. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $4,243 behind.
The break-even point in Franklin Town
Gas would only overtake the heat pump in Franklin Town if electricity rose past 32.0¢/kWh from 30.15¢, or gas fell under $23.59 per Mcf from $25.06. A useful quote test for Franklin Town: the heat pump is worth it within a decade if it costs less than $840 more than replacing the furnace and AC, and within 7 years if the gap is under $588.
The other scenario: no gas furnace to begin with
Not every home in Franklin Town has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $2,831 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 3.5 years.
How Franklin Town compares nationally
