Venango County, PA Insulation Payback
Venango County, PA: what topping up your attic actually costs
Venango County sits in IECC climate zone 5 (Cold) — winters that dominate the energy bill, with cooling a minor factor. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $1,796/year saved. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $1,702/year heating, $94/year cooling. Out of every 100 US counties tracked here, Venango County's savings potential beats roughly 72 of them. Within zone 5 specifically, it ranks 304th of 745 counties by estimated savings. Pennsylvania averages $1,724/year across the counties tracked here; Venango County comes in 4% higher.
The climate data behind this
NOAA's FRANKLIN, PA US station, 3.4 miles from Venango County, supplies the 6,365 HDD and 584 CDD this estimate runs on. That combined heating-and-cooling load ranks Venango County 940th nationally by total degree days — the 70th percentile. Venango County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $262/year saved — roughly 8.7 years to break even. This one is a genuine toss-up, not a clear yes.
