Heat Pump Payback in Naugatuck, CT
Naugatuck, CT: the heat pump payback math
Here in Naugatuck, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Naugatuck would pay extra to go electric rather than replace the furnace and AC with the same again. Running costs here land $368 a year higher than the furnace it replaces, so that premium is never recovered. That's Naugatuck's own climate and rates talking, not a hedge or a caveat.

Naugatuck's weather, in the numbers that matter
5472 heating degree days pile up here every year, so Naugatuck has a cold winter that leans hard on heating equipment; the cooling side runs to 579 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 10°F here (coldest 2024 reading -0.9°F), which works out to a seasonal COP of 2.94 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Naugatuck sits firmly in cold-climate territory, so that's the class of unit priced here.

Naugatuck's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,713 heating kilowatt-hours annually on top of cooling, totalling about $1,551 a year on electricity. The gas furnace it replaces burns roughly 57 Mcf a year at $16.83 per Mcf here, for a running cost near $1,183 a year including the old AC (electricity here runs 29.78¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $11,019 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Naugatuck's result is to prices
For the verdict in Naugatuck to flip, electricity would need to drop to about 21.5¢/kWh from 29.78¢, or gas climb past $23.29 per Mcf from $16.83. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Naugatuck; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Naugatuck heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $2,799 a year, which recovers the extra $10,000 spent going electric in roughly 3.6 years.
How Naugatuck compares nationally
Among 3206 cities, Naugatuck's winter puts it at rank 391 for severity, while its size puts it at rank 1272 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.
What to do with this number in Naugatuck
Naugatuck, Connecticut is home to about 32,116 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Naugatuck, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
