Heat Pump Payback in White House, TN
Is a heat pump worth it in White House?
White House technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $136 saved annually, for a payback of roughly 40.3 years. That's a technicality, not a recommendation, for anyone actually living in White House.

How cold White House actually gets
Degree days tell the story here: White House racks up 2807 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2098 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 8.6°F, and the coldest daily reading in the 2024 station record was -2.2°F. That puts the seasonal coefficient of performance at 2.91 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 8.6°F design temperature White House falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. Climate figures trace to the nearest NOAA station, John C Tune, 23 miles from White House.
The yearly running costs in White House
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,443 kWh a year to keep it warm, plus cooling, for a combined electric bill near $587 a year. The gas furnace it replaces burns roughly 29 Mcf a year at $11.84 per Mcf here, for a running cost near $723 a year including the old AC (electricity here runs 13.87¢/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 $3,454 behind.
What would change White House's answer
Gas would only overtake the heat pump in White House if electricity rose past 22.9¢/kWh from 13.87¢, or gas fell under $7.18 per Mcf from $11.84. A useful quote test for White House: the heat pump is worth it within a decade if it costs less than $1,360 more than replacing the furnace and AC, and within 7 years if the gap is under $952.
Electric resistance heat in White House, compared
Plenty of homes in White House heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and White House's answer improves. The saving here runs about $776 a year, which recovers the extra $10,000 spent going electric in roughly 12.9 years.
White House against the rest of the country
Among 3206 cities, White House's winter puts it at rank 1994 for severity, while its size puts it at rank 2250 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
