Heat Pump Payback in Monroeville, PA
Should Monroeville switch to a heat pump?
Monroeville technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Monroeville would pay extra to go electric rather than replace the furnace and AC with the same again. Monroeville's residents would see roughly $17 a year back in running costs, putting the payback around 323.1 years. Monroeville's own numbers say this pencils out only in theory, not in practice.

Why Monroeville's climate drives this number
Degree days tell the story here: Monroeville racks up 4313 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1220 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 10°F here (coldest 2024 reading 8.1°F), which works out to a seasonal COP of 2.94 for the cold-climate class of unit this climate calls for. Monroeville 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. Climate figures trace to the nearest NOAA station, Allegheny County Airport, 9.8 miles from Monroeville.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,715 kWh a year to keep it warm, plus cooling, for a combined electric bill near $987 a year. The gas furnace it replaces burns roughly 45 Mcf a year at $15.04 per Mcf here, for a running cost near $1,004 a year including the old AC (electricity here runs 20.75¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $5,245 behind.
What would change Monroeville's answer
This result holds unless electricity climbs above 21.3¢/kWh (it is 20.75¢ now) or gas drops below $14.66 per Mcf (now $15.04); past either point, gas becomes the cheaper fuel in Monroeville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $17 a year saved, a difference under $119 pays back within 7 years here, and under $170 within 10.
Electric resistance heat in Monroeville, compared
Not every home in Monroeville has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,608 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 6.2 years.
Where Monroeville ranks in this dataset

Where Monroeville's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Monroeville's 2.94 seasonal COP and payback figure. Monroeville's 10°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
