Bulloch County, GA Insulation Payback

Bulloch County attic insulation, by the numbers

Bulloch County, Georgia is zone 3 under DOE's climate map (Hot-Humid), which means long, muggy summers and mild winters, where cooling dominates the energy bill. An uninsulated attic there should be built 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 $892 a year — payback in roughly 3.2 years. Topping up the attic pays for itself here.

Where the savings come from

Split it out and it's roughly $508 a year on the heating side, $384 on cooling. By estimated insulation savings, Bulloch County lands in the 10th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Bulloch County comes in 645th by savings. Georgia averages $974/year across the counties tracked here; Bulloch County comes in 8% lower.

Bulloch County's actual weather, not a national average

NOAA's BROOKLET 1 W, GA US station, 4.1 miles from Bulloch County, supplies the 1,913 HDD and 2,412 CDD this estimate runs on. Combined heating and cooling load puts Bulloch County in the 7th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Bulloch County sits in moisture regime A (humid), which can affect the vapor-barrier choice.

If the attic isn't bare

Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $120/year saved — roughly 13.5 years to break even. Call this borderline rather than a clear win.

Quotes and materials for this job

Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Bulloch County job, not a quote. Expect at least a $600 minimum charge from most contractors.
