Heat Pump Payback in Sherwood, AR
Heat pump vs. gas furnace in Sherwood, AR
In Sherwood, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Sherwood's residents would see roughly $359 a year back in running costs, putting the payback around 15.3 years. That's a technicality, not a recommendation, for anyone actually living in Sherwood.

How cold Sherwood actually gets
Degree days tell the story here: Sherwood racks up 2606 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2216 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 11.8°F here (coldest 2024 reading -2.6°F), which works out to a seasonal COP of 2.98 for the cold-climate class of unit this climate calls for. Mild on average, but the occasional cold snap is what sizes the equipment: at a 11.8°F design temperature Sherwood falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe.

Sherwood's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 2,214 heating kilowatt-hours annually on top of cooling, totalling about $545 a year on electricity. That compares with roughly 27 Mcf a year of gas at Sherwood's $19.25 per-Mcf rate, about $904 a year with the old AC included, against a local electricity rate of 13.28¢/kWh. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $117 behind.
What would change Sherwood's answer
Gas would only overtake the heat pump in Sherwood if electricity rose past 42.4¢/kWh from 13.28¢, or gas fell under $6.03 per Mcf from $19.25. A useful quote test for Sherwood: the heat pump is worth it within a decade if it costs less than $3,590 more than replacing the furnace and AC, and within 7 years if the gap is under $2,513.
The other scenario: no gas furnace to begin with
Gas isn't universal in Sherwood, 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 $713 a year, which recovers the extra $10,000 spent going electric in roughly 14 years.
Where Sherwood ranks in this dataset
Among 3206 cities, Sherwood's winter puts it at rank 2095 for severity, while its size puts it at rank 1233 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Sherwood
Sherwood, Arkansas is home to about 33,281 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 Sherwood, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Sherwood's 2.98 seasonal COP and payback figure. Sherwood's 11.8°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.
