Schleicher County, TX Insulation Payback
Attic insulation payback for Schleicher County, TX
DOE classifies Schleicher County as climate zone 3, hot-dry — intense summer heat with low humidity, where attic radiant heat gain is the main driver. Its recommended attic R-value for bare joists is 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 2.8 years at an estimated $993/year saved. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $661/year comes from reduced heating and $333/year from reduced cooling load through the ceiling. Schleicher County beats 16% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 690 counties DOE places in zone 3, Schleicher County ranks 486th. Against Texas's own average of $1,035/year, Schleicher County runs 4% below that.
The climate data behind this
Schleicher County's climate figures — 2,490 heating and 2,087 cooling degree days a year — are read from ELDORADO, TX US, 4.7 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Schleicher County sits at the 13th percentile nationally. DOE also classifies Schleicher County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
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 $134/year saved (~12.1-year payback). It is close - the payback only just fits a reasonable timeframe.
Getting it done in Schleicher County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $2,820 figure above as a planning number for Schleicher County, not a bid - contractors typically charge a $600 minimum regardless of job size.
