Love County, OK Insulation Payback
Is attic insulation worth it in Love County, OK?
Love County, Oklahoma 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 2.5 years at an estimated $1,131/year saved. Few home upgrades pay back that quickly.
Where the savings come from
Heating accounts for about $774/year of that and cooling about $357/year — Love County needs both. Nationally, Love County ranks in the 26th percentile for insulation savings potential. Compared only against its own climate zone, Love County places 191st out of 690. Against Oklahoma's own average of $1,260/year, Love County runs 10% below that.
The climate data behind this
Love County's climate figures — 2,917 heating and 2,242 cooling degree days a year — are read from BURNEYVILLE 2SE MESONT, OK US, 4.6 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Love County sits at the 30th 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?
If Love County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-38. That smaller top-up costs around $1,620 and saves an estimated $152/year — payback about 10.6 years. Whether that is worth it depends on how long you plan to stay.
