Amherst Town, MA: the heat pump payback math
In Amherst Town, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $60 saved annually, for a payback of roughly 58.2 years. Amherst Town's own numbers say this pencils out only in theory, not in practice.
Why Amherst Town's climate drives this number
5424 heating degree days pile up here every year, so Amherst Town has a cold winter that leans hard on heating equipment; the cooling side runs to 767 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 5.9°F here (record low 0.9°F), which works out to a seasonal COP of 2.84 for the cold-climate class of unit this climate calls for. Amherst 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
Electricity use for heating alone comes out to about 4,836 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,655 a year. Amherst Town's gas rate of 25.06 per Mcf, applied to the 56 Mcf a year the furnace burns, puts its running cost near $1,715 a year, against 30.15¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 224.7 years, for a 15-year net position $2,599 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Amherst Town heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Amherst Town's answer improves. Switching saves about $2,785 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 2.9 years.
Amherst Town against the rest of the country
Ranked against the other 3206 cities covered, Amherst Town comes in at 418 for heating severity — 1 would be the coldest place in the dataset — and 999 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

The methodology guide walks through exactly how Amherst Town's 2.84 seasonal COP and the rest of this page's numbers get built. Amherst Town's 5.9°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.
