Heat pump vs. gas furnace in Dothan, AL
In Dothan, a heat pump pays for itself within a reasonable window. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Lower bills claw that back: about $266 saved annually, for a payback of roughly 3.8 years. That's a real payback, built from Dothan's own climate and utility rates, not a national guess.
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 (record low 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 — against a local electricity rate of 16.62¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 41.3 years, for a 15-year net position $2,991 ahead.
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 8.9-year payback clears the $5,500 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.
