Maverick County, TX Insulation Payback
Attic insulation payback for Maverick County, TX
DOE classifies Maverick County as climate zone 2, hot-humid — summers that stay hot and humid while winters barely register on the energy bill. Its recommended attic R-value for bare joists is 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 $904 a year in heating and cooling — a payback around 3.1 years. Worth doing on the numbers alone.
Heating vs. cooling in Maverick County
Of that, about $371/year comes from reduced heating and $532/year from reduced cooling load through the ceiling. Maverick County beats 10% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 233 counties DOE places in zone 2, Maverick County ranks 37th. Against Texas's own average of $1,035/year, Maverick County runs 13% below that.
The climate data behind this
Maverick County's climate figures — 1,400 heating and 3,339 cooling degree days a year — are read from EAGLE PASS 3N, TX US, 10 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Maverick County sits at the 18th percentile nationally. DOE also classifies Maverick County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
