McCreary County, KY Insulation Payback
Is attic insulation worth it in McCreary County, KY?
McCreary County sits in IECC climate zone 4 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to 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 $1,386 a year — payback in roughly 2.5 years. Few home upgrades pay back that quickly.
The breakdown behind the number
Heating accounts for about $1,234/year of that and cooling about $152/year — McCreary County needs both. Nationally, McCreary County ranks in the 45th percentile for insulation savings potential. Compared only against its own climate zone, McCreary County places 416th out of 825. Against Kentucky's own average of $1,385/year, McCreary County runs 0% above that.
McCreary County's actual weather, not a national average
NOAA's STEARNS 2S, KY US station, 4 miles from McCreary County, supplies the 4,615 HDD and 948 CDD this estimate runs on. Combined heating and cooling load puts McCreary County in the 41th 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?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $202/year saved — roughly 11.3 years to break even. Whether that is worth it depends on how long you plan to stay.
Quotes and materials for this job
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 McCreary County job, not a quote. Expect at least a $600 minimum charge from most contractors.
