Hudspeth County, TX Insulation Payback
Hudspeth County, TX: what topping up your attic actually costs
Hudspeth County, Texas is zone 3 under DOE's climate map (Hot-Dry), which means scorching, dry summers where heat radiating straight through the roof does most of the damage. 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 $1,085 a year — payback in roughly 2.6 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $831/year heating, $254/year cooling. Out of every 100 US counties tracked here, Hudspeth County's savings potential beats roughly 23 of them. Within zone 3 specifically, it ranks 275th of 690 counties by estimated savings. Texas averages $1,035/year across the counties tracked here; Hudspeth County comes in 5% higher.
Hudspeth County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 3,132 HDD and 1,593 CDD (base 65°F, 1991-2020 normals) — come from CORNUDAS SVC STN, TX US, the nearest NOAA station with published normals, 23.4 miles from Hudspeth County's center. Combined heating and cooling load puts Hudspeth County in the 18th percentile of this 3,162-county dataset. Hudspeth County falls in DOE's moisture regime B (dry), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
If Hudspeth 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 $146/year — payback about 11.1 years. This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-49 is the target here specifically.
