HeatPumpPayback

Should Farmington switch to a heat pump?

Farmington sits right on the fence — how long you'll own the house decides this one. $3,500 is what Farmington would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $340 saved annually, for a payback of roughly 10.3 years. It's a genuine toss-up here — Farmington's numbers don't point clearly either way.

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 record low of -9.9°F on file. 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 — against a local electricity rate of 13.28¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 39.7 years, for a 15-year net position $1,600 ahead.

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 10.7-year payback clears the $8,000 premium comfortably within the equipment's life.

Where Farmington ranks in this dataset

Ranked against the other 3206 cities covered, Farmington comes in at 1910 for heating severity — 1 would be the coldest place in the dataset — and 3095 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Next step for 10,473 people in Farmington

Farmington, Arkansas is home to about 10,473 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 Farmington, nothing is lost by holding off until the current equipment genuinely fails.

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.
