Heat Pump Payback in Farmington, AR
Should Farmington switch to a heat pump?
Farmington technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Farmington would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $340 saved annually, for a payback of roughly 16.2 years. That's a technicality, not a recommendation, for anyone actually living in Farmington.

How cold Farmington actually gets
Farmington has a real but manageable winter, 3026 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1825 cooling degree days. 1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -9.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.72 on the cold-climate unit fit for this climate. Farmington 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. These numbers come from Drake Field Airport, the closest NOAA station, 5 miles out.
Farmington's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,817 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $581 a year. That compares with roughly 32 Mcf a year of gas at Farmington's $19.25 per-Mcf rate, about $921 a year with the old AC included, against a local electricity rate of 13.28¢/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 $400 behind.
The break-even point in Farmington
Gas would only overtake the heat pump in Farmington if electricity rose past 30.2¢/kWh from 13.28¢, or gas fell under $8.46 per Mcf from $19.25. A useful quote test for Farmington: the heat pump is worth it within a decade if it costs less than $3,400 more than replacing the furnace and AC, and within 7 years if the gap is under $2,380.
The other scenario: no gas furnace to begin with
Plenty of homes in Farmington heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $751 a year comes back this way, enough that the 13.3-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Farmington ranks in this dataset

Every constant behind this page, the 2.72 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Farmington's 1°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.
