Franklin County, NE Insulation Payback

Is attic insulation worth it in Franklin County, NE?

Franklin 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. 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 $1,794 a year in heating and cooling — a payback around 1.9 years. Few home upgrades pay back that quickly.

Heating vs. cooling in Franklin County

Heating accounts for about $1,622/year of that and cooling about $172/year — Franklin County needs both. Nationally, Franklin County ranks in the 72th percentile for insulation savings potential. Compared only against its own climate zone, Franklin County places 310th out of 745. Against Nebraska's own average of $1,872/year, Franklin County runs 4% below that.

Franklin County's actual weather, not a national average

The heating and cooling degree days behind this estimate — 6,065 HDD and 1,071 CDD (base 65°F, 1991-2020 normals) — come from FRANKLIN #2, NE US, the nearest NOAA station with published normals, 6.1 miles from Franklin County's center. Combined heating and cooling load puts Franklin County in the 74th 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.

If the attic isn't bare

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 $262/year saved (~8.7-year payback). Whether that is worth it depends on how long you plan to stay.

Next steps for a Franklin County attic

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 Franklin County, not a bid - contractors typically charge a $600 minimum regardless of job size.
