Red River County, TX Insulation Payback
Is attic insulation worth it in Red River County, TX?
Red River County, Texas is zone 3 under DOE's climate map (Hot-Humid), which means long, muggy summers and mild winters, where cooling dominates the energy bill. An uninsulated attic there should be built 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 $1,098 a year in heating and cooling — a payback around 2.6 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Red River County
Heating accounts for about $756/year of that and cooling about $341/year — Red River County needs both. Nationally, Red River County ranks in the 24th percentile for insulation savings potential. Compared only against its own climate zone, Red River County places 241st out of 690. Against Texas's own average of $1,035/year, Red River County runs 6% above that.
The climate data behind this
Red River County's climate figures — 2,850 heating and 2,142 cooling degree days a year — are read from CLARKSVILLE 2NE, TX US, 1.4 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Red River County in the 26th percentile of this 3,162-county dataset. 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.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $148/year saved — roughly 11 years to break even. Whether that is worth it depends on how long you plan to stay.
