Should Valley switch to a heat pump?
Valley sits right on the fence — how long you'll own the house decides this one. 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. That premium is recovered through $252 of lower running costs every year, landing the payback clock at roughly 13.9 years. It's a genuine toss-up here — Valley's numbers don't point clearly either way.
How cold Valley actually gets
Degree days tell the story here: Valley racks up 2422 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1790 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 19.2°F, against a record low of 12.4°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Valley needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. Climate figures trace to the nearest NOAA station, LAGRANGE-CALLAWAY AIRPORT, 15.8 miles from Valley.
The month-to-month numbers for Valley
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,941 kWh a year to keep it warm, plus cooling, for a combined electric bill near $576 a year. The gas furnace it replaces burns roughly 25 Mcf a year at 17.56 per Mcf here, for a running cost near $828 a year (electricity here runs 16.62¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 53.5 years, leaving the 15-year total $284 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Valley — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $829 a year, which recovers the extra $8,000 spent going electric in roughly 9.7 years.
Valley against the rest of the country
Valley lands at position 2227 out of 3206 cities on heating severity (coldest is 1), and 3168 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.
Deciding what's next in Valley, AL
Valley, Alabama is home to about 10,144 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 Valley, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
The methodology guide walks through exactly how Valley's 3.16 seasonal COP and the rest of this page's numbers get built. Valley's 19.2°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
