Heat Pump Payback in Binghamton, NY
Binghamton, NY: the heat pump payback math
In Binghamton, a heat pump would cost more to run each year than what you have now. $5,500 is what Binghamton would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $439 a year here, so the extra spend stays unrecovered. That's Binghamton's own climate and rates talking, not a hedge or a caveat.

Binghamton's weather, in the numbers that matter
Degree days tell the story here: Binghamton racks up 6104 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 476 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 3.9°F here (coldest 2024 reading -4°F), which works out to a seasonal COP of 2.79 for the cold-climate class of unit this climate calls for. Binghamton 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. These numbers come from Greater Binghamton/E A Link F, the closest NOAA station, 8.1 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 5,540 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,737 a year. The gas furnace it replaces burns roughly 64 Mcf a year at $17.58 per Mcf here, for a running cost near $1,298 a year including the old AC (electricity here runs 29.22¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $12,092 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Binghamton's result is to prices
For the verdict in Binghamton to flip, electricity would need to drop to about 21.0¢/kWh from 29.22¢, or gas climb past $24.49 per Mcf from $17.58. 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 Binghamton; 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 Binghamton 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 $2,959 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 3.4 years.
Binghamton against the rest of the country
Binghamton lands at position 176 out of 3206 cities on heating severity (coldest is 1), and 874 out of 3206 by population size (biggest is 1). 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 Binghamton
Binghamton, New York is home to about 46,773 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 Binghamton, nothing is lost by holding off until the current equipment genuinely fails.
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 Binghamton's 2.79 seasonal COP and payback figure. Binghamton's 3.9°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.
