Chicot County, AR Insulation Payback
Chicot County attic insulation, by the numbers
Chicot County sits in IECC climate zone 3 (Mixed-Humid) — real heating and real cooling seasons both, roughly balanced across the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $1,048 a year — payback in roughly 2.7 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $671 a year on the heating side, $378 on cooling. By estimated insulation savings, Chicot County lands in the 20th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Chicot County comes in 364th by savings. Arkansas averages $1,185/year across the counties tracked here; Chicot County comes in 12% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 2,528 HDD and 2,370 CDD (base 65°F, 1991-2020 normals) — come from EUDORA, AR US, the nearest NOAA station with published normals, 10.7 miles from Chicot County's center. Combined heating and cooling load puts Chicot County in the 23th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Chicot County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
If Chicot County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-38. That smaller top-up costs around $1,620 and saves an estimated $141/year — payback about 11.5 years. Call this borderline rather than a clear win.
Quotes and materials for this job
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $2,820 figure above as a planning number for Chicot County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Chicot County's R-49 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-49 is the target here specifically.
