Should Murrysville switch to a heat pump?
The payback math works in Murrysville on paper, past the equipment's own working life. $3,500 is what Murrysville would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $17 saved annually, for a payback of roughly 205.6 years. Murrysville's own numbers say this pencils out only in theory, not in practice.
The climate behind Murrysville's payback figure
Degree days tell the story here: Murrysville 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. 10°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 8.1°F on file. Worked through the model, that's a seasonal COP of 2.94 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Murrysville sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, ALLEGHENY COUNTY AIRPORT, 15.1 miles from Murrysville.
The month-to-month numbers for Murrysville
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. That compares with roughly 45 Mcf a year of gas at Murrysville's 15.04 per-Mcf rate — about $1,004 a year — against a local electricity rate of 20.75¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 793.2 years, for a 15-year net position $3,245 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Murrysville 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. About $1,608 a year comes back this way, enough that the 5-year payback clears the $8,000 premium comfortably within the equipment's life.
How Murrysville compares nationally
Among 3206 cities, Murrysville's winter puts it at rank 1311 for severity, while its size puts it at rank 1863 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
