Heat Pump Payback in Braselton, GA
Heat pump vs. gas furnace in Braselton, GA
The payback math works in Braselton on paper, past the equipment's own working life. $5,500 is what Braselton would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $338 saved annually, for a payback of roughly 16.3 years. That's a technicality, not a recommendation, for anyone actually living in Braselton.

How cold Braselton actually gets
Degree days tell the story here: Braselton racks up 2485 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1835 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 12.9°F, and the coldest daily reading in the 2024 station record was 12.9°F. That puts the seasonal coefficient of performance at 3.01 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 12.9°F design temperature Braselton 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.

The yearly running costs in Braselton
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,090 kWh a year to keep it warm, plus cooling, for a combined electric bill near $545 a year. That compares with roughly 26 Mcf a year of gas at Braselton's $20.42 per-Mcf rate, about $883 a year with the old AC included, against a local electricity rate of 14.90¢/kWh. 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 $427 behind.
What would change Braselton's answer
Gas would only overtake the heat pump in Braselton if electricity rose past 41.4¢/kWh from 14.90¢, or gas fell under $7.35 per Mcf from $20.42. A useful quote test for Braselton: the heat pump is worth it within a decade if it costs less than $3,380 more than replacing the furnace and AC, and within 7 years if the gap is under $2,366.
Electric resistance heat in Braselton, compared
Not every home in Braselton has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $747 a year, which recovers the extra $10,000 spent going electric in roughly 13.4 years.
Braselton against the rest of the country
Among 3206 cities, Braselton's winter puts it at rank 2192 for severity, while its size puts it at rank 2152 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
Next step if you live in Braselton
Braselton, Georgia is home to about 17,390 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 Braselton, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
Where Braselton's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Braselton's 3.01 seasonal COP and payback figure. At a 12.9°F design temperature, Braselton sits in cold-climate territory; the guide to that class of unit explains why.
