Will a heat pump pay off in Sandy Springs, GA?
Sandy Springs sits right on the fence — how long you'll own the house decides this one. $3,500 is what Sandy Springs would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Sandy Springs's residents would see roughly $344 a year back in running costs, putting the payback around 10.2 years. It's a genuine toss-up here — Sandy Springs's numbers don't point clearly either way.
How cold Sandy Springs actually gets
Degree days tell the story here: Sandy Springs racks up 2569 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1846 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°F, against a record low of 10.9°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. Sandy Springs 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.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 2,176 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $559 a year. That compares with roughly 27 Mcf a year of gas at Sandy Springs's 20.42 per-Mcf rate — about $903 a year — against a local electricity rate of 14.90¢/kWh. Buy it outright, not incrementally, and payback stretches to 39.2 years; over 15 years the net position sits $1,662 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Sandy Springs heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $767 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 10.4 years.
