Heat Pump Payback in Ephrata, PA
Ephrata, PA: the heat pump payback math
Ephrata is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Ephrata would pay extra to go electric rather than replace the furnace and AC with the same again. The heat pump would cost about $4 more a year to run than the furnace it replaces, a premium with no payback. That's Ephrata's own climate and rates talking, not a hedge or a caveat.

Ephrata's weather, in the numbers that matter
Ephrata has a real but manageable winter, 4332 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1145 cooling degree days. Sizing runs off the design temperature, not the average day: 8.1°F here (coldest 2024 reading 7°F), which works out to a seasonal COP of 2.89 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Ephrata, 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
A 2000-square-foot house here would pull roughly 3,796 heating kilowatt-hours annually on top of cooling, totalling about $990 a year on electricity. Ephrata's gas rate of $15.04 per Mcf, applied to the 45 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $986 a year, against 20.75¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $5,555 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Ephrata's answer
For the verdict in Ephrata to flip, electricity would need to drop to about 20.6¢/kWh from 20.75¢, or gas climb past $15.12 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 Ephrata; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Not every home in Ephrata has gas service. Swap the comparison to resistance heat instead of gas, and Ephrata's answer improves. The saving here runs about $1,594 a year, which recovers the extra $10,000 spent going electric in roughly 6.3 years.
