Oswego, NY: the heat pump payback math
In Oswego, 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 $3,500 more up front here (already netting out a $2,000 tax credit). Running costs here land $355 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Oswego's numbers say wait.
Why Oswego's climate drives this number
5649 heating degree days pile up here every year, so Oswego has a cold winter that leans hard on heating equipment; the cooling side runs to 595 cooling degree days, where summers add a moderate cooling load. 6.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -5.1°F on file. Worked through the model, that's a seasonal COP of 2.85 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Oswego sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from OSWEGO COUNTY AIRPORT, the closest NOAA station, 9.6 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 5,019 heating kilowatt-hours annually on top of cooling, totalling about $1,615 a year on electricity. The gas furnace it replaces burns roughly 59 Mcf a year at 17.58 per Mcf here, for a running cost near $1,260 a year (electricity here runs 29.22¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $8,828 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Oswego heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $2,790 a year, which recovers the extra $8,000 spent going electric in roughly 2.9 years.
Oswego against the rest of the country
Ranked against the other 3206 cities covered, Oswego comes in at 329 for heating severity — 1 would be the coldest place in the dataset — and 2188 by population, where 1 is largest. 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 Oswego
About 17,047 people live in Oswego, 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.
Ask a local HVAC contractor for a quote before committing either way.
Where Oswego's figure comes from
The methodology guide walks through exactly how Oswego's 2.85 seasonal COP and the rest of this page's numbers get built. At a 6.1°F design temperature, Oswego sits in cold-climate territory; the guide to that class of unit explains why.
