Heat Pump Payback in Rochester, NY
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 $5,500 more up front here. 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, and the coldest daily reading in the 2024 station record was 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 including the old AC (electricity here runs 29.22¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $10,306 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Rochester
For the verdict in Rochester to flip, electricity would need to drop to about 22.0¢/kWh from 29.22¢, or gas climb past $23.40 per Mcf from $17.58. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Rochester; the case for one here rests on comfort, cooling, or replacing electric heat instead.
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 $10,000 spent going electric in roughly 3.8 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.
