Cochran County, TX Insulation Payback
Attic insulation payback for Cochran County, TX
DOE classifies Cochran County as climate zone 4, mixed-dry — dry heat in summer giving way to a properly cold winter. Its recommended attic R-value for bare joists is R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,218 a year in heating and cooling — a payback around 2.9 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Cochran County
Of that, about $964/year comes from reduced heating and $255/year from reduced cooling load through the ceiling. Cochran County beats 32% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Cochran County ranks 727th. Against Texas's own average of $1,035/year, Cochran County runs 18% above that.
Where these numbers come from
The heating and cooling degree days behind this estimate — 3,605 HDD and 1,585 CDD (base 65°F, 1991-2020 normals) — come from MORTON, TX US, the nearest NOAA station with published normals, 8.7 miles from Cochran County's center. That combined heating-and-cooling load ranks Cochran County 2186th nationally by total degree days — the 31th percentile. DOE also classifies Cochran County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
If the attic isn't bare
If Cochran County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $178/year — payback about 12.8 years. It is close - the payback only just fits a reasonable timeframe.
Getting it done in Cochran County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Cochran County, not a bid - contractors typically charge a $600 minimum regardless of job size.
