Lynn County, TX Insulation Payback
Lynn County attic insulation, by the numbers
Lynn County, Texas is zone 3 under DOE's climate map (Hot-Dry), which means desert-dry heat for much of the year, with the attic taking the brunt of it. An uninsulated attic there should be built up to R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $1,133 a year — payback in roughly 2.5 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $822 a year on the heating side, $311 on cooling. By estimated insulation savings, Lynn County lands in the 27th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Lynn County comes in 188th by savings. Texas averages $1,035/year across the counties tracked here; Lynn County comes in 9% higher.
Where these numbers come from
Lynn County's climate figures — 3,098 heating and 1,951 cooling degree days a year — are read from TAHOKA, TX US, 1.3 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Lynn County 2300th nationally by total degree days — the 27th percentile. One local detail the R-value alone won't tell you: Lynn County sits in moisture regime B (dry), which can affect the vapor-barrier choice.
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 $153/year saved — roughly 10.6 years to break even. Call this borderline rather than a clear win.
Quotes and materials for this job
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Lynn County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Lynn County's R-49 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-49 is the target here specifically.
