Clearfield County, PA Insulation Payback
Attic insulation payback for Clearfield County, PA
DOE classifies Clearfield County as climate zone 6, cold — cold enough that heating, not cooling, is what decides the bill. Its recommended attic R-value for bare joists is R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,788 a year — payback in roughly 1.9 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,709/year comes from reduced heating and $79/year from reduced cooling load through the ceiling. Clearfield County beats 71% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 459 counties DOE places in zone 6, Clearfield County ranks 456th. Against Pennsylvania's own average of $1,724/year, Clearfield County runs 4% above that.
Where these numbers come from
NOAA's CLEARFIELD LAWRENCE AP, PA US station, 4.4 miles from Clearfield County, supplies the 6,391 HDD and 491 CDD this estimate runs on. Combined heating and cooling load puts Clearfield County in the 69th percentile of this 3,162-county dataset. DOE also classifies Clearfield 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
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $261/year saved — roughly 8.7 years to break even. It is close - the payback only just fits a reasonable timeframe.
