Cuming County, NE Insulation Payback
Attic insulation payback for Cuming County, NE
DOE classifies Cuming 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. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,958 a year in heating and cooling — a payback around 1.8 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Cuming County
Of that, about $1,812/year comes from reduced heating and $147/year from reduced cooling load through the ceiling. Cuming County beats 80% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Cuming County ranks 84th. Against Nebraska's own average of $1,872/year, Cuming County runs 5% above that.
The climate data behind this
The heating and cooling degree days behind this estimate — 6,775 HDD and 914 CDD (base 65°F, 1991-2020 normals) — come from W PT, NE US, the nearest NOAA station with published normals, 6.2 miles from Cuming County's center. That combined heating-and-cooling load ranks Cuming County 570th nationally by total degree days — the 82th percentile. DOE also classifies Cuming County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $286/year saved — roughly 8 years to break even. Topping up the attic pays for itself here.
Next steps for a Cuming County attic
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 Cuming County job, not a quote. Expect at least a $600 minimum charge from most contractors.
