Heat Pump Payback in Bridgeport, CT
Should Bridgeport switch to a heat pump?
In Bridgeport, a heat pump would cost more to run each year than what you have now. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Running costs here land $210 a year higher than the furnace it replaces, so that premium is never recovered. There's no spin on that: Bridgeport's numbers say wait.

Why Bridgeport's climate drives this number
Degree days tell the story here: Bridgeport racks up 4566 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 791 cooling degree days on the cooling side. 16.2°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 8.8°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.09 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Bridgeport, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, Bridgeport, 1.5 miles from Bridgeport.
Bridgeport's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,742 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,315 a year. The gas furnace it replaces burns roughly 48 Mcf a year at $16.83 per Mcf here, for a running cost near $1,106 a year including the old AC (electricity here runs 29.78¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $8,643 behind.
What would change Bridgeport's answer
The heat pump would become the cheaper option in Bridgeport if electricity fell to 23.6¢/kWh (from 29.78¢) or gas rose above $21.24 per Mcf (from $16.83). At today's prices a cheaper quote cannot rescue the gas comparison in Bridgeport, since there is no yearly saving to recover it from.
Electric resistance heat in Bridgeport, compared
Plenty of homes in Bridgeport 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. Switching saves about $2,433 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 4.1 years.
How Bridgeport compares nationally
Among 3206 cities, Bridgeport's winter puts it at rank 1121 for severity, while its size puts it at rank 180 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 Bridgeport
About 151,599 people live in Bridgeport, Connecticut, 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.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Bridgeport's 3.09 seasonal COP and payback figure. At a 16.2°F design temperature, Bridgeport sits in cold-climate territory; the guide to that class of unit explains why.
