Is a heat pump worth it in New Bedford?
New Bedford 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. Lower bills claw that back: about $150 saved annually, for a payback of roughly 23.3 years. New Bedford's own numbers say this pencils out only in theory, not in practice.
The climate behind New Bedford's payback figure
Degree days tell the story here: New Bedford racks up 5048 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 752 cooling degree days on the cooling side. 14°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 10.9°F on file. Worked through the model, that's a seasonal COP of 3.04 on the cold-climate unit fit for this climate. New Bedford 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.

New Bedford's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,205 heating kilowatt-hours annually on top of cooling, totalling about $1,461 a year on electricity. New Bedford's gas rate of 25.06 per Mcf, applied to the 53 Mcf a year the furnace burns, puts its running cost near $1,611 a year, against 30.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 89.8 years; over 15 years the net position sits $1,246 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in New Bedford — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and New Bedford's answer improves. The saving here runs about $2,687 a year, which recovers the extra $8,000 spent going electric in roughly 3 years.
How New Bedford compares nationally
Ranked against the other 3206 cities covered, New Bedford comes in at 654 for heating severity — 1 would be the coldest place in the dataset — and 334 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
Deciding what's next in New Bedford, MA
About 101,318 people live in New Bedford, 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
Every constant behind this page — the 3.04 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. New Bedford's 14°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
