Lowell, AR: the heat pump payback math
In Lowell, 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). Lower bills claw that back: about $350 saved annually, for a payback of roughly 10 years. It's a genuine toss-up here — Lowell's numbers don't point clearly either way.
How cold Lowell actually gets
Degree days tell the story here: Lowell racks up 2629 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2323 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 5°F, against a record low of -5.8°F. That puts the seasonal coefficient of performance at 2.82 for the recommended cold-climate unit. A cold-climate unit is the right call in Lowell — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Lowell's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,361 kWh a year to keep it warm, plus cooling, for a combined electric bill near $577 a year. Lowell's gas rate of 19.25 per Mcf, applied to the 27 Mcf a year the furnace burns, puts its running cost near $927 a year, against 13.28¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 38.5 years, leaving the 15-year total $1,755 ahead.
The other scenario: no gas furnace to begin with
Not every home in Lowell has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $707 a year comes back this way, enough that the 11.3-year payback clears the $8,000 premium comfortably within the equipment's life.
How Lowell compares nationally
Lowell lands at position 2084 out of 3206 cities on heating severity (coldest is 1), and 2880 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Lowell
Lowell, Arkansas is home to about 11,568 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 Lowell, nothing is lost by holding off until the current equipment genuinely fails.

Where Lowell's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Lowell's 2.82 seasonal COP and payback figure. Lowell's 5°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
