Heat Pump Payback in Anderson, SC
Is a heat pump worth it in Anderson?
Anderson technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Anderson would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $243 saved annually, for a payback of roughly 22.6 years. That's a technicality, not a recommendation, for anyone actually living in Anderson.

How cold Anderson actually gets
2439 heating degree days pile up here every year, so Anderson has a mild winter by US standards; the cooling side runs to 1922 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 16°F, and the coldest daily reading in the 2024 station record was 10.9°F. That puts the seasonal coefficient of performance at 3.08 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 16°F design temperature Anderson 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 Anderson
Electricity use for heating alone comes out to about 2,005 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $589 a year. That compares with roughly 25 Mcf a year of gas at Anderson's $16.91 per-Mcf rate, about $832 a year with the old AC included, against a local electricity rate of 16.16¢/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 $1,852 behind.
How sensitive Anderson's result is to prices
Gas would only overtake the heat pump in Anderson if electricity rose past 37.3¢/kWh from 16.16¢, or gas fell under $7.34 per Mcf from $16.91. A useful quote test for Anderson: the heat pump is worth it within a decade if it costs less than $2,430 more than replacing the furnace and AC, and within 7 years if the gap is under $1,701.
If your home heats with electric baseboard instead of gas
Plenty of homes in Anderson heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Anderson's answer improves. About $812 a year comes back this way, enough that the 12.3-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Anderson ranks in this dataset
Ranked against the other 3206 cities covered, Anderson comes in at 2209 for heating severity, 1 would be the coldest place in the dataset, and 1317 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
