Ochiltree County, TX Insulation Payback

Ochiltree County, TX: what topping up your attic actually costs

Ochiltree 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. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,355 a year in heating and cooling — a payback around 2.6 years. That's about as fast as attic paybacks get.

Where the savings come from

The estimated savings split roughly $1,058/year heating, $297/year cooling. Out of every 100 US counties tracked here, Ochiltree County's savings potential beats roughly 42 of them. Within zone 4 specifically, it ranks 476th of 825 counties by estimated savings. Texas averages $1,035/year across the counties tracked here; Ochiltree County comes in 31% higher.

Ochiltree County's actual weather, not a national average

The heating and cooling degree days behind this estimate — 3,957 HDD and 1,848 CDD (base 65°F, 1991-2020 normals) — come from PERRYTON, TX US, the nearest NOAA station with published normals, 7.7 miles from Ochiltree County's center. Combined heating and cooling load puts Ochiltree County in the 47th percentile of this 3,162-county dataset. Ochiltree County falls in DOE's moisture regime B (dry), a detail that affects vapor-barrier recommendations more than the R-value target itself.

The smaller top-up scenario

If Ochiltree County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $198/year — payback about 11.5 years. This one is a genuine toss-up, not a clear yes.

Next steps for a Ochiltree County attic

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 Ochiltree County job, not a quote. Expect at least a $600 minimum charge from most contractors.

Nothing here is a guess
