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 $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $136 saved annually, for a payback of roughly 25.7 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, against a record low of -2.2°F. That puts the seasonal coefficient of performance at 2.91 for the recommended cold-climate unit. White House 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, JOHN C TUNE, 23 miles from White House.
The month-to-month numbers for 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 (electricity here runs 13.87¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 99 years, for a 15-year net position $1,454 behind.
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 $8,000 spent going electric in roughly 10.3 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.
What to do with this number in White House
White House, Tennessee is home to about 16,463 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In White House, nothing is lost by holding off until the current equipment genuinely fails.

Where White House's figure comes from
Every constant behind this page — the 2.91 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. White House's 8.6°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
