Heat Pump Payback in Erie, PA
Is a heat pump worth it in Erie?
In Erie, a heat pump would cost more to run each year than what you have now. $5,500 is what Erie would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $25 a year here, so the extra spend stays unrecovered. That's Erie's own climate and rates talking, not a hedge or a caveat.

How cold Erie actually gets
4871 heating degree days pile up here every year, so Erie has a real but manageable winter; the cooling side runs to 893 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 10°F here (coldest 2024 reading 6.1°F), which works out to a seasonal COP of 2.94 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Erie, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,195 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,029 a year. That compares with roughly 51 Mcf a year of gas at Erie's $15.04 per-Mcf rate, about $1,003 a year with the old AC included, against a local electricity rate of 20.75¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $5,881 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Erie's answer
For the verdict in Erie to flip, electricity would need to drop to about 20.1¢/kWh from 20.75¢, or gas climb past $15.54 per Mcf from $15.04. 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 Erie; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Erie heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Erie's answer improves. The saving here runs about $1,771 a year, which recovers the extra $10,000 spent going electric in roughly 5.6 years.
How Erie compares nationally
Among 3206 cities, Erie's winter puts it at rank 878 for severity, while its size puts it at rank 375 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.

Erie, Pennsylvania is home to about 92,940 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 Erie, nothing is lost by holding off until the current equipment genuinely fails.
