Should Phenix City switch to a heat pump?
In Phenix City, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Phenix City's residents would see roughly $287 a year back in running costs, putting the payback around 12.2 years. Whether that's worth it in Phenix City depends on how many years you expect to own the place.
Why Phenix City's climate drives this number
Degree days tell the story here: Phenix City racks up 1708 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2636 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 24.1°F, against a record low of 17.1°F. That puts the seasonal coefficient of performance at 3.28 for the recommended cold-climate unit. A cold-climate unit is the right call in Phenix City — 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, COLUMBUS METRO AIRPORT, 6.7 miles from Phenix City.
The month-to-month numbers for Phenix City
A 2000-square-foot house here would pull roughly 1,319 heating kilowatt-hours annually on top of cooling, totalling about $593 a year on electricity. That compares with roughly 18 Mcf a year of gas at Phenix City's 17.56 per-Mcf rate — about $880 a year — against a local electricity rate of 16.62¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 47 years, leaving the 15-year total $812 ahead.
Electric resistance heat in Phenix City, compared
Plenty of homes in Phenix City heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Phenix City's answer improves. The saving here runs about $694 a year, which recovers the extra $8,000 spent going electric in roughly 11.5 years.
Phenix City against the rest of the country
