Will a heat pump pay off in Harrison, NY?

Here in Harrison, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Running costs here land $164 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Harrison's numbers say wait.

The climate behind Harrison's payback figure

4760 heating degree days pile up here every year, so Harrison has a real but manageable winter; the cooling side runs to 888 cooling degree days, where summers add a moderate cooling load. 15.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 6.1°F on file. Worked through the model, that's a seasonal COP of 3.06 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Harrison — 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, WESTCHESTER COUNTY AIRPORT, 2.8 miles from Harrison.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 3,939 heating kilowatt-hours annually on top of cooling, totalling about $1,372 a year on electricity. Harrison's gas rate of 17.58 per Mcf, applied to the 50 Mcf a year the furnace burns, puts its running cost near $1,208 a year, against 29.22¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $5,966 behind.

The other scenario: no gas furnace to begin with

Plenty of homes in Harrison 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 $2,486 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 3.2 years.

Where Harrison ranks in this dataset

Among 3206 cities, Harrison's winter puts it at rank 980 for severity, while its size puts it at rank 1307 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.

About 31,321 people live in Harrison, 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.
