Heat Pump Payback in Ithaca, NY
Is a heat pump worth it in Ithaca?
Ithaca is a place where a heat pump genuinely costs more to operate than the alternative. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $410 a year here, so the extra spend stays unrecovered. There's no spin on that: Ithaca's numbers say wait.

The climate behind Ithaca's payback figure
6010 heating degree days pile up here every year, so Ithaca has a cold winter that leans hard on heating equipment; the cooling side runs to 511 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 5°F, and the coldest daily reading in the 2024 station record was -7.1°F. That puts the seasonal coefficient of performance at 2.82 for the recommended cold-climate unit. Ithaca 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 Ithaca Tompkins Regional Airp, the closest NOAA station, 3.3 miles out.
Ithaca's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,396 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,704 a year. That compares with roughly 63 Mcf a year of gas at Ithaca's $17.58 per-Mcf rate, about $1,294 a year with the old AC included, against a local electricity rate of 29.22¢/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 $11,654 behind.
The break-even point in Ithaca
The heat pump would become the cheaper option in Ithaca if electricity fell to 21.3¢/kWh (from 29.22¢) or gas rose above $24.13 per Mcf (from $17.58). At today's prices a cheaper quote cannot rescue the gas comparison in Ithaca, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Plenty of homes in Ithaca 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. About $2,936 a year comes back this way, enough that the 3.4-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Ithaca ranks in this dataset
Among 3206 cities, Ithaca's winter puts it at rank 227 for severity, while its size puts it at rank 1217 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 Ithaca
About 33,768 people live in Ithaca, New York, 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.

Where Ithaca's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Ithaca's 2.82 seasonal COP and payback figure. Ithaca's 5°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.
