Huntingdon County, PA Insulation Payback
Huntingdon County attic insulation, by the numbers
Huntingdon County, Pennsylvania 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 2.1 years at an estimated $1,621/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,486 a year on the heating side, $135 on cooling. By estimated insulation savings, Huntingdon County lands in the 61th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Huntingdon County comes in 615th by savings. Pennsylvania averages $1,724/year across the counties tracked here; Huntingdon County comes in 6% lower.
Huntingdon County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 5,558 HDD and 840 CDD (base 65°F, 1991-2020 normals) — come from RAYSTOWN LAKE 2, PA US, the nearest NOAA station with published normals, 6.3 miles from Huntingdon County's center. By total degree days, Huntingdon County sits at the 60th percentile nationally. One local detail the R-value alone won't tell you: Huntingdon County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
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 $236/year saved — roughly 9.6 years to break even. Call this borderline rather than a clear win.

Where these figures come from
Huntingdon 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.
