Howard County, NE Insulation Payback
Is attic insulation worth it in Howard County, NE?
DOE classifies Howard County as climate zone 5, cold — cold enough that heating, not cooling, is what decides the bill. Its recommended attic R-value for bare joists is 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 years at an estimated $1,774/year saved. Few home upgrades pay back that quickly.
The breakdown behind the number
Heating accounts for about $1,592/year of that and cooling about $181/year — Howard County needs both. Nationally, Howard County ranks in the 70th percentile for insulation savings potential. Compared only against its own climate zone, Howard County places 353rd out of 745. Against Nebraska's own average of $1,872/year, Howard County runs 5% below that.
Where these numbers come from
Howard County's climate figures — 5,955 heating and 1,129 cooling degree days a year — are read from SAINT PAUL, NE US, 2.8 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Howard County in the 73th 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 $259/year saved (~8.8-year payback). Whether that is worth it depends on how long you plan to stay.
