Baldwin County, GA Insulation Payback
Baldwin County attic insulation, by the numbers
Baldwin County sits in IECC climate zone 3 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. 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 $993 a year — payback in roughly 2.8 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Baldwin County
Split it out and it's roughly $658 a year on the heating side, $335 on cooling. By estimated insulation savings, Baldwin County lands in the 16th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Baldwin County comes in 481st by savings. Georgia averages $974/year across the counties tracked here; Baldwin County comes in 2% higher.
The climate data behind this
Baldwin County's climate figures — 2,480 heating and 2,103 cooling degree days a year — are read from MILLEDGEVILLE, GA US, 1.7 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Baldwin County in the 13th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Baldwin County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
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 $134/year saved (~12.1-year payback). Call this borderline rather than a clear win.
Next steps for a Baldwin County attic
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 Baldwin County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Baldwin 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.
