Ector County, TX Insulation Payback
Ector County attic insulation, by the numbers
Ector 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. 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 2.7 years at an estimated $1,044/year saved. Topping up the attic pays for itself fast here.
Heating vs. cooling in Ector County
Split it out and it's roughly $600 a year on the heating side, $444 on cooling. By estimated insulation savings, Ector County lands in the 20th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Ector County comes in 372nd by savings. Texas averages $1,035/year across the counties tracked here; Ector County comes in 1% higher.
Where these numbers come from
Ector County's climate figures — 2,261 heating and 2,786 cooling degree days a year — are read from PENWELL, TX US, 9.4 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Ector County sits at the 27th percentile nationally. One local detail the R-value alone won't tell you: Ector County sits in moisture regime B (dry), which can affect the vapor-barrier choice.
Already have some insulation?
If Ector 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 $141/year — payback about 11.5 years. Call this borderline rather than a clear win.
Next steps for a Ector County attic
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 Ector County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Ector 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.
