Should Lovejoy switch to a heat pump?
This one's marginal in Lovejoy: it only clears if you stay long enough. $3,500 is what Lovejoy 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. Lovejoy's residents would see roughly $339 a year back in running costs, putting the payback around 10.3 years. It's a genuine toss-up here — Lovejoy's numbers don't point clearly either way.
How cold Lovejoy actually gets
2093 heating degree days pile up here every year, so Lovejoy has a mild winter by US standards; the cooling side runs to 2333 cooling degree days, where summers are hot enough that cooling matters as much as heating. 14°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12.9°F on file. Worked through the model, that's a seasonal COP of 3.04 on the cold-climate unit fit for this climate. Lovejoy 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. These numbers come from HARTSFIELD-JACKSON ATLANTA IN, the closest NOAA station, 14.7 miles out.
The month-to-month numbers for Lovejoy
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,743 kWh a year to keep it warm, plus cooling, for a combined electric bill near $556 a year. Lovejoy's gas rate of 20.42 per Mcf, applied to the 22 Mcf a year the furnace burns, puts its running cost near $896 a year, against 14.90¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 39.8 years, leaving the 15-year total $1,592 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Lovejoy 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 $684 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 11.7 years.
Where Lovejoy ranks in this dataset
Among 3206 cities, Lovejoy's winter puts it at rank 2389 for severity, while its size puts it at rank 2713 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 for 12,612 people in Lovejoy
Lovejoy, Georgia is home to about 12,612 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 Lovejoy, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Lovejoy's 3.04 seasonal COP and payback figure. Lovejoy's 14°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
