Will a heat pump pay off in Quincy, MA?
In Quincy, 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). Lower bills claw that back: about $177 saved annually, for a payback of roughly 19.8 years. Quincy's own numbers say this pencils out only in theory, not in practice.
Why Quincy's climate drives this number
4588 heating degree days pile up here every year, so Quincy has a real but manageable winter; the cooling side runs to 874 cooling degree days, where summers add a moderate cooling load. 15.8°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 11.7°F on file. Worked through the model, that's a seasonal COP of 3.08 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Quincy — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Quincy
A 2000-square-foot house here would pull roughly 3,772 heating kilowatt-hours annually on top of cooling, totalling about $1,362 a year on electricity. Quincy's gas rate of 25.06 per Mcf, applied to the 48 Mcf a year the furnace burns, puts its running cost near $1,539 a year, against 30.15¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 76.3 years, leaving the 15-year total $844 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Quincy — 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. About $2,482 a year comes back this way, enough that the 3.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Quincy against the rest of the country
Among 3206 cities, Quincy's winter puts it at rank 1103 for severity, while its size puts it at rank 322 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Quincy
About 103,434 people live in Quincy, 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.
More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Quincy's 3.08 seasonal COP and payback figure. Quincy's 15.8°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
