HeatPumpPayback

Should Lackawanna switch to a heat pump?

Here in Lackawanna, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Lackawanna would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. The heat pump would cost about $296 more a year to run than the furnace it replaces — a premium with no payback. That's Lackawanna's own climate and rates talking, not a hedge or a caveat.

How cold Lackawanna actually gets

Degree days tell the story here: Lackawanna racks up 5278 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 831 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 6.1°F here (record low 3°F), which works out to a seasonal COP of 2.85 for the cold-climate class of unit this climate calls for. Lackawanna 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.

Lackawanna's running-cost comparison, in dollars

Modelled on a typical 2000-square-foot house, the heat pump draws about 4,689 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,577 a year. Lackawanna's gas rate of 17.58 per Mcf, applied to the 55 Mcf a year the furnace burns, puts its running cost near $1,281 a year, against 29.22¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,943 behind.

The other scenario: no gas furnace to begin with

Not every home in Lackawanna has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $2,643 a year, which recovers the extra $8,000 spent going electric in roughly 3 years.

Where Lackawanna ranks in this dataset

Ranked against the other 3206 cities covered, Lackawanna comes in at 517 for heating severity — 1 would be the coldest place in the dataset — and 1959 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 Lackawanna

Lackawanna, New York is home to about 19,629 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 Lackawanna, nothing is lost by holding off until the current equipment genuinely fails.

Where Lackawanna's figure comes from

The methodology guide walks through exactly how Lackawanna's 2.85 seasonal COP and the rest of this page's numbers get built. Lackawanna's 6.1°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.
