Why Macon-Bibb County's climate drives this number
Macon-Bibb County has a mild winter by US standards, 2059 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2161 cooling degree days. 16°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 16°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.08 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 16°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Macon-Bibb County. These numbers come from Middle Georgia Regional Airpo, the closest NOAA station, 8.9 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,693 heating kilowatt-hours annually on top of cooling, totalling about $527 a year on electricity. The gas furnace it replaces burns roughly 21 Mcf a year at $20.42 per Mcf here, for a running cost near $855 a year including the old AC (electricity here runs 14.90¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $574 behind.
How sensitive Macon-Bibb County's result is to prices
This result holds unless electricity climbs above 59.6¢/kWh (it is 14.90¢ now) or gas drops below $5.10 per Mcf (now $20.42); past either point, gas becomes the cheaper fuel in Macon-Bibb County. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $328 a year saved, a difference under $2,296 pays back within 7 years here, and under $3,280 within 10.
If your home heats with electric baseboard instead of gas
Not every home in Macon-Bibb County has gas service. Swap the comparison to resistance heat instead of gas, and Macon-Bibb County's answer improves. The saving here runs about $667 a year, which recovers the extra $10,000 spent going electric in roughly 15 years.
How Macon-Bibb County compares nationally
Macon-Bibb County lands at position 2416 out of 3206 cities on heating severity (coldest is 1), and 172 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
