Should Lynn switch to a heat pump?
Lynn technically pencils out, but only past the point the equipment would need replacing anyway. 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. Lynn's residents would see roughly $107 a year back in running costs, putting the payback around 32.8 years. Lynn's own numbers say this pencils out only in theory, not in practice.
The climate behind Lynn's payback figure
5701 heating degree days pile up here every year, so Lynn has a cold winter that leans hard on heating equipment; the cooling side runs to 667 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 10.9°F, against a record low of -0.9°F. That puts the seasonal coefficient of performance at 2.96 for the recommended cold-climate unit. A cold-climate unit is the right call in Lynn — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from BEVERLY MUNICIPAL AIRPORT, the closest NOAA station, 7.9 miles out.
Lynn's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,877 heating kilowatt-hours annually on top of cooling, totalling about $1,642 a year on electricity. Lynn's gas rate of 25.06 per Mcf, applied to the 59 Mcf a year the furnace burns, puts its running cost near $1,749 a year, against 30.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 126.5 years; over 15 years the net position sits $1,900 behind.
Electric resistance heat in Lynn, compared
Gas isn't universal in Lynn — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $2,971 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 2.7 years.
How Lynn compares nationally
Among 3206 cities, Lynn's winter puts it at rank 316 for severity, while its size puts it at rank 321 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
Next step for 103,489 people in Lynn
About 103,489 people live in Lynn, Massachusetts, 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.
Ask a local HVAC contractor for a quote before committing either way.

The methodology guide walks through exactly how Lynn's 2.96 seasonal COP and the rest of this page's numbers get built. Lynn'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.
