Heat Pump Payback in Dothan, AL
Heat pump vs. gas furnace in Dothan, AL
In Dothan, 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 $3,000. Lower bills claw that back: about $266 saved annually, for a payback of roughly 11.3 years. Whether that's worth it in Dothan depends on how many years you expect to own the place.

The climate behind Dothan's payback figure
Dothan barely has a winter to speak of, 1483 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 2753 cooling degree days. Sizing runs off the design temperature, not the average day: 27°F here (coldest 2024 reading 19°F), which works out to a seasonal COP of 3 for the standard class of unit this climate calls for. A standard ducted system is enough here; Dothan's design temperature doesn't justify the cold-climate premium. These numbers come from Dothan Regional Airport, the closest NOAA station, 6.3 miles out.
Dothan's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 1,252 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $598 a year. That compares with roughly 15 Mcf a year of gas at Dothan's $17.56 per-Mcf rate, about $864 a year with the old AC included, against a local electricity rate of 16.62¢/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 $991 ahead.
How sensitive Dothan's result is to prices
This result holds unless electricity climbs above 871.4¢/kWh (it is 16.62¢ now) or gas drops below $0.33 per Mcf (now $17.56); past either point, gas becomes the cheaper fuel in Dothan. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $266 a year saved, a difference under $1,862 pays back within 7 years here, and under $2,660 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Dothan, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Dothan's answer improves. About $619 a year comes back this way, enough that the 12.1-year payback clears the $7,500 premium comfortably within the equipment's life.
How Dothan compares nationally
Dothan lands at position 2698 out of 3206 cities on heating severity (coldest is 1), and 539 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.

Where Dothan's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Dothan's 3 seasonal COP and payback figure. Not every home in Dothan has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
