Bedford County, VA Insulation Payback
Bedford County, VA: what topping up your attic actually costs
DOE classifies Bedford County as climate zone 4, mixed-humid — real heating and real cooling seasons both, roughly balanced across the year. Its recommended attic R-value for bare joists is 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 $1,273 a year in heating and cooling — a payback around 2.7 years. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $1,086/year heating, $187/year cooling. Out of every 100 US counties tracked here, Bedford County's savings potential beats roughly 36 of them. Within zone 4 specifically, it ranks 635th of 825 counties by estimated savings. Virginia averages $1,342/year across the counties tracked here; Bedford County comes in 5% lower.
Where these numbers come from
NOAA's BEDFORD, VA US station, 1.9 miles from Bedford County, supplies the 4,062 HDD and 1,162 CDD this estimate runs on. Combined heating and cooling load puts Bedford County in the 32th percentile of this 3,162-county dataset. Bedford County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
If Bedford 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 $186/year — payback about 12.3 years. This one is a genuine toss-up, not a clear yes.
