Texas County, OK Insulation Payback
Texas County, OK: what topping up your attic actually costs
Texas County sits in IECC climate zone 4 (Mixed-Dry) — big seasonal swings - a dry hot summer, then a real winter cold snap. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.5 years at an estimated $1,411/year saved. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,148/year heating, $263/year cooling. Out of every 100 US counties tracked here, Texas County's savings potential beats roughly 46 of them. Within zone 4 specifically, it ranks 364th of 825 counties by estimated savings. Oklahoma averages $1,260/year across the counties tracked here; Texas County comes in 12% higher.
The climate data behind this
The heating and cooling degree days behind this estimate — 4,293 HDD and 1,640 CDD (base 65°F, 1991-2020 normals) — come from GUYMON MUNI AP, OK US, the nearest NOAA station with published normals, 4.6 miles from Texas County's center. Combined heating and cooling load puts Texas County in the 50th percentile of this 3,162-county dataset. Texas County falls in DOE's moisture regime B (dry), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $206/year saved (~11.1-year payback). This one is a genuine toss-up, not a clear yes.
Getting it done in Texas County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Texas County job, not a quote. Expect at least a $600 minimum charge from most contractors.
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-60 is the target here specifically.
