Pike County, IL Insulation Payback
Is attic insulation worth it in Pike County, IL?
Pike 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 2.2 years at an estimated $1,618/year saved. Few home upgrades pay back that quickly.
Heating vs. cooling in Pike County
Heating accounts for about $1,417/year of that and cooling about $201/year — Pike County needs both. Nationally, Pike County ranks in the 61th percentile for insulation savings potential. Compared only against its own climate zone, Pike County places 619th out of 745. Against Illinois's own average of $1,642/year, Pike County runs 1% below that.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,301 HDD and 1,252 CDD (base 65°F, 1991-2020 normals) — come from PITTSFIELD #2, IL US, the nearest NOAA station with published normals, 4.6 miles from Pike County's center. That combined heating-and-cooling load ranks Pike County 1181st nationally by total degree days — the 63th percentile. 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 $236/year saved (~9.7-year payback). Whether that is worth it depends on how long you plan to stay.
Getting it done in Pike County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Pike County job, not a quote. Expect at least a $600 minimum charge from most contractors.
