Heat Pump Payback in Jefferson Hills, PA
Will a heat pump pay off in Jefferson Hills, PA?
In Jefferson Hills, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $17 of lower running costs every year, landing the payback clock at roughly 323.1 years. That's a technicality, not a recommendation, for anyone actually living in Jefferson Hills.

How cold Jefferson Hills actually gets
Degree days tell the story here: Jefferson Hills 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. Jefferson Hills 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, 4.1 miles from Jefferson Hills.
The yearly running costs in Jefferson Hills
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. Jefferson Hills'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 $1,004 a year, against 20.75¢ per kWh for electricity. 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 Jefferson Hills's answer
Gas would only overtake the heat pump in Jefferson Hills if electricity rose past 21.3¢/kWh from 20.75¢, or gas fell under $14.66 per Mcf from $15.04. A useful quote test for Jefferson Hills: the heat pump is worth it within a decade if it costs less than $170 more than replacing the furnace and AC, and within 7 years if the gap is under $119.
If your home heats with electric baseboard instead of gas
Not every home in Jefferson Hills has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,608 a year, which recovers the extra $10,000 spent going electric in roughly 6.2 years.
Jefferson Hills against the rest of the country

Where Jefferson Hills's figure comes from
The methodology guide walks through exactly how Jefferson Hills's 2.94 seasonal COP and the rest of this page's numbers get built. Jefferson Hills's 10°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
