Pecos County, TX Insulation Payback
Attic insulation payback for Pecos County, TX
Pecos County sits in IECC climate zone 3 (Hot-Dry) — scorching, dry summers where heat radiating straight through the roof does most of the damage. 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 $952 a year in heating and cooling — a payback around 3 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $539/year comes from reduced heating and $414/year from reduced cooling load through the ceiling. Pecos County beats 13% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 690 counties DOE places in zone 3, Pecos County ranks 567th. Against Texas's own average of $1,035/year, Pecos County runs 8% below that.
The climate data behind this
Pecos County's climate figures — 2,030 heating and 2,596 cooling degree days a year — are read from FT STOCKTON, TX US, 14.9 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Pecos County sits at the 14th percentile nationally. DOE also classifies Pecos County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
If Pecos 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 $128/year — payback about 12.6 years. It is close - the payback only just fits a reasonable timeframe.
