Centre County, PA Insulation Payback
Attic insulation payback for Centre County, PA
Centre County, Pennsylvania is zone 5 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. 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 2 years at an estimated $1,724/year saved. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Centre County
Of that, about $1,617/year comes from reduced heating and $107/year from reduced cooling load through the ceiling. Centre County beats 68% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Centre County ranks 436th. Against Pennsylvania's own average of $1,724/year, Centre County runs 0% above that.
Centre County's actual weather, not a national average
Centre County's climate figures — 6,049 heating and 666 cooling degree days a year — are read from STATE COLLEGE, PA US, 8.1 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Centre County 1071st nationally by total degree days — the 66th percentile. DOE also classifies Centre County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
If Centre 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 $252/year — payback about 9.1 years. It is close - the payback only just fits a reasonable timeframe.
