Cedartown, GA: the heat pump payback math
In Cedartown, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Cedartown's residents would see roughly $348 a year back in running costs, putting the payback around 10.1 years. Whether that's worth it in Cedartown depends on how many years you expect to own the place.
The climate behind Cedartown's payback figure
Cedartown has a mild winter by US standards — 2694 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1448 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 19.4°F, against a record low of 8.6°F. That puts the seasonal coefficient of performance at 3.17 for the recommended cold-climate unit. Cedartown 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 PAULDING NORTHWEST ATLANTA AI, the closest NOAA station, 19.2 miles out.
The month-to-month numbers for Cedartown
Electricity use for heating alone comes out to about 2,152 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $505 a year. The gas furnace it replaces burns roughly 28 Mcf a year at 20.42 per Mcf here, for a running cost near $853 a year (electricity here runs 14.90¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 38.8 years, for a 15-year net position $1,719 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Cedartown 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. The saving here runs about $791 a year, which recovers the extra $8,000 spent going electric in roughly 10.1 years.
Cedartown against the rest of the country
Cedartown lands at position 2039 out of 3206 cities on heating severity (coldest is 1), and 3122 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
