Holmes County, OH Insulation Payback
Holmes County, OH: what topping up your attic actually costs
Holmes County sits in IECC climate zone 5 (Cold) — cold enough that heating, not cooling, is what decides the bill. 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 $1,723 a year in heating and cooling — a payback around 2 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,617/year heating, $107/year cooling. Out of every 100 US counties tracked here, Holmes County's savings potential beats roughly 68 of them. Within zone 5 specifically, it ranks 437th of 745 counties by estimated savings. Ohio averages $1,669/year across the counties tracked here; Holmes County comes in 3% higher.
Where these numbers come from
NOAA's MILLERSBURG, OH US station, 2 miles from Holmes County, supplies the 6,046 HDD and 664 CDD this estimate runs on. By total degree days, Holmes County sits at the 66th percentile nationally. Holmes County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
If Holmes 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 $251/year — payback about 9.1 years. This one is a genuine toss-up, not a clear yes.
