Morgan County, GA Insulation Payback
Attic insulation payback for Morgan County, GA
Morgan County, Georgia is zone 3 under DOE's climate map (Mixed-Humid), which means real heating and real cooling seasons both, roughly balanced across the year. An uninsulated attic there should be built up to R-49. Going from R-2 to the recommended R-49 costs roughly $2,820 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.8 years at an estimated $1,010/year saved. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $740/year comes from reduced heating and $270/year from reduced cooling load through the ceiling. Morgan County beats 18% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 690 counties DOE places in zone 3, Morgan County ranks 447th. Against Georgia's own average of $974/year, Morgan County runs 4% above that.
Morgan County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 2,789 HDD and 1,694 CDD (base 65°F, 1991-2020 normals) — come from WATKINSVILLE 5 SSE, GA US, the nearest NOAA station with published normals, 14.3 miles from Morgan County's center. Combined heating and cooling load puts Morgan County in the 11th percentile of this 3,162-county dataset. DOE also classifies Morgan County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
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 $136/year saved (~11.9-year payback). It is close - the payback only just fits a reasonable timeframe.
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 Morgan County, not a bid - contractors typically charge a $600 minimum regardless of job size.
