Erie County, OH Insulation Payback
Is attic insulation worth it in Erie County, OH?
Erie County sits in IECC climate zone 5 (Cold) — cold enough that heating, not cooling, is what decides the bill. 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 2.1 years at an estimated $1,665/year saved. Few home upgrades pay back that quickly.
Heating vs. cooling in Erie County
Heating accounts for about $1,512/year of that and cooling about $153/year — Erie County needs both. Nationally, Erie County ranks in the 64th percentile for insulation savings potential. Compared only against its own climate zone, Erie County places 546th out of 745. Against Ohio's own average of $1,669/year, Erie County runs 0% above that.
The climate data behind this
NOAA's SANDUSKY, OH US station, 7.8 miles from Erie County, supplies the 5,653 HDD and 953 CDD this estimate runs on. Combined heating and cooling load puts Erie County in the 64th percentile of this 3,162-county dataset. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.
Already have some insulation?
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $243/year saved (~9.4-year payback). Whether that is worth it depends on how long you plan to stay.
Quotes and materials for this job
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Erie County, not a bid - contractors typically charge a $600 minimum regardless of job size.
