Will a heat pump pay off in Perry, GA?
In Perry, 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. Perry's residents would see roughly $326 a year back in running costs, putting the payback around 10.8 years. It's a genuine toss-up here — Perry's numbers don't point clearly either way.
How cold Perry actually gets
1762 heating degree days pile up here every year, so Perry has a mild winter by US standards; the cooling side runs to 2471 cooling degree days, where summers are hot enough that cooling matters as much as heating. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 15.8°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Perry — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, ROBINS AFB AIRPORT, 13.3 miles from Perry.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 1,425 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $526 a year. That compares with roughly 18 Mcf a year of gas at Perry's 20.42 per-Mcf rate — about $852 a year — against a local electricity rate of 14.90¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 41.5 years, for a 15-year net position $1,384 ahead.
Electric resistance heat in Perry, compared
Not every home in Perry has gas service. Swap the comparison to resistance heat instead of gas, and Perry's answer improves. The saving here runs about $616 a year, which recovers the extra $8,000 spent going electric in roughly 13 years.
Perry against the rest of the country
Among 3206 cities, Perry's winter puts it at rank 2562 for severity, while its size puts it at rank 1620 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.
What to do with this number in Perry
Perry, Georgia is home to about 24,792 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 Perry, nothing is lost by holding off until the current equipment genuinely fails.
