Quitman County, GA Insulation Payback
Quitman County attic insulation, by the numbers
DOE classifies Quitman County as climate zone 3, hot-humid — humid heat for much of the year, with cooling running far more than heating ever does. Its recommended attic R-value for bare joists is 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 $939 a year — payback in roughly 3 years. Topping up the attic pays for itself here.
Where the savings come from
Split it out and it's roughly $669 a year on the heating side, $270 on cooling. By estimated insulation savings, Quitman County lands in the 12th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Quitman County comes in 597th by savings. Georgia averages $974/year across the counties tracked here; Quitman County comes in 4% lower.
The climate data behind this
Quitman County's climate figures — 2,521 heating and 1,694 cooling degree days a year — are read from GEORGETOWN 4 E, GA US, 3 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Quitman County 3011th nationally by total degree days — the 5th percentile. One local detail the R-value alone won't tell you: Quitman County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
A shallower starting point changes the math: with R-11 already down, only the gap to R-38 needs filling, at roughly $1,620 for an estimated $126/year saved (~12.8-year payback). 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 Quitman County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Quitman 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.
