Should Rochester switch to a heat pump?

In Rochester, 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). Unfortunately the electric bill outweighs the gas bill it replaces by about $320 a year here, so the extra spend stays unrecovered. That's Rochester's own climate and rates talking, not a hedge or a caveat.

Rochester's weather, in the numbers that matter

Degree days tell the story here: Rochester racks up 5285 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 761 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 5°F, against a record low of 0°F. That puts the seasonal coefficient of performance at 2.82 for the recommended cold-climate unit. A cold-climate unit is the right call in Rochester — 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, GREATER ROCHESTER INTERNATION, 4.7 miles from Rochester.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 4,746 heating kilowatt-hours annually on top of cooling, totalling about $1,576 a year on electricity. The gas furnace it replaces burns roughly 55 Mcf a year at 17.58 per Mcf here, for a running cost near $1,256 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 $8,306 behind.

Electric resistance heat in Rochester, compared

Plenty of homes in Rochester 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 $2,622 a year, which recovers the extra $8,000 spent going electric in roughly 3.1 years.

Rochester against the rest of the country

Rochester lands at position 503 out of 3206 cities on heating severity (coldest is 1), and 119 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.

Deciding what's next in Rochester, NY

Rochester, New York is home to about 207,282 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 Rochester, nothing is lost by holding off until the current equipment genuinely fails.

Where Rochester's figure comes from

Nothing above is a black box: the methodology guide shows the full arithmetic behind Rochester's 2.82 seasonal COP and payback figure. At a 5°F design temperature, Rochester sits in cold-climate territory; the guide to that class of unit explains why.
