Conecuh County, AL Insulation Payback
Is attic insulation worth it in Conecuh County, AL?
DOE classifies Conecuh County as climate zone 3, hot-humid — summers that stay hot and humid while winters barely register on the energy bill. 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 $913 a year — payback in roughly 3.1 years. That is a solid payback as home upgrades go.
Where the savings come from
Heating accounts for about $558/year of that and cooling about $354/year — Conecuh County needs both. Nationally, Conecuh County ranks in the 11th percentile for insulation savings potential. Compared only against its own climate zone, Conecuh County places 630th out of 690. Against Alabama's own average of $1,001/year, Conecuh County runs 9% below that.
The climate data behind this
The heating and cooling degree days behind this estimate — 2,105 HDD and 2,224 CDD (base 65°F, 1991-2020 normals) — come from EVERGREEN, AL US, the nearest NOAA station with published normals, 2.3 miles from Conecuh County's center. By total degree days, Conecuh County sits at the 7th percentile nationally. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $123/year saved — roughly 13.2 years to break even. Whether that is worth it depends on how long you plan to stay.
