Stephens County, TX Insulation Payback
Is attic insulation worth it in Stephens County, TX?
Stephens County sits in IECC climate zone 3 (Mixed-Humid) — real heating and real cooling seasons both, roughly balanced across the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-49 runs an estimated $2,820, and saves about $1,130 a year in heating and cooling — a payback around 2.5 years. Few home upgrades pay back that quickly.
The breakdown behind the number
Heating accounts for about $749/year of that and cooling about $381/year — Stephens County needs both. Nationally, Stephens County ranks in the 26th percentile for insulation savings potential. Compared only against its own climate zone, Stephens County places 194th out of 690. Against Texas's own average of $1,035/year, Stephens County runs 9% above that.
Stephens County's actual weather, not a national average
NOAA's BRECKENRIDGE, TX US station, 3.7 miles from Stephens County, supplies the 2,823 HDD and 2,389 CDD this estimate runs on. By total degree days, Stephens County sits at the 32th 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.
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 $152/year saved (~10.6-year payback). Whether that is worth it depends on how long you plan to stay.
