Heat Pump Payback in Mount Washington, KY
Heat pump vs. gas furnace in Mount Washington, KY
In Mount Washington, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. That premium is recovered through $192 of lower running costs every year, landing the payback clock at roughly 28.6 years. That's a technicality, not a recommendation, for anyone actually living in Mount Washington.

Mount Washington's weather, in the numbers that matter
Mount Washington has a real but manageable winter, 3192 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1992 cooling degree days. Sizing runs off the design temperature, not the average day: 6.1°F here (coldest 2024 reading 3°F), which works out to a seasonal COP of 2.85 for the cold-climate class of unit this climate calls for. Mount Washington 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.

Mount Washington's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,836 kWh a year to keep it warm, plus cooling, for a combined electric bill near $653 a year. The gas furnace it replaces burns roughly 33 Mcf a year at $14.23 per Mcf here, for a running cost near $845 a year including the old AC (electricity here runs 14.39¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $2,619 behind.
How sensitive Mount Washington's result is to prices
Gas would only overtake the heat pump in Mount Washington if electricity rose past 24.2¢/kWh from 14.39¢, or gas fell under $8.45 per Mcf from $14.23. A useful quote test for Mount Washington: the heat pump is worth it within a decade if it costs less than $1,920 more than replacing the furnace and AC, and within 7 years if the gap is under $1,344.
Electric resistance heat in Mount Washington, compared
Gas isn't universal in Mount Washington, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $882 a year comes back this way, enough that the 11.3-year payback clears the $10,000 premium comfortably within the equipment's life.
