Eureka County, NV Insulation Payback
Eureka County attic insulation, by the numbers
Eureka County, Nevada is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. An uninsulated attic there should be built 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 1.9 years at an estimated $1,833/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,768 a year on the heating side, $65 on cooling. By estimated insulation savings, Eureka County lands in the 74th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Eureka County comes in 237th by savings. Nevada averages $1,643/year across the counties tracked here; Eureka County comes in 12% higher.
Eureka County's actual weather, not a national average
NOAA's BEOWAWE 49S - U OF N RCH, NV US station, 17.5 miles from Eureka County, supplies the 6,613 HDD and 406 CDD this estimate runs on. That combined heating-and-cooling load ranks Eureka County 893rd nationally by total degree days — the 72th percentile. One local detail the R-value alone won't tell you: Eureka County sits in moisture regime B (dry), which can affect the vapor-barrier choice.
The smaller top-up scenario
If Eureka 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 $267/year — payback about 8.5 years. Call this borderline rather than a clear win.
Quotes and materials for this job
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 Eureka County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Eureka County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
