Eddy County, ND Insulation Payback
Attic insulation payback for Eddy County, ND
Eddy County sits in IECC climate zone 7 (Very Cold) — winters long and harsh enough that heating is essentially the entire equation. 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 $2,562 a year — payback in roughly 1.4 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Eddy County
Of that, about $2,495/year comes from reduced heating and $67/year from reduced cooling load through the ceiling. Eddy County beats 98% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 120 counties DOE places in zone 7, Eddy County ranks 51st. Against North Dakota's own average of $2,496/year, Eddy County runs 3% above that.
The climate data behind this
Eddy County's climate figures — 9,330 heating and 417 cooling degree days a year — are read from MC HENRY 3W, ND US, 15.5 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Eddy County sits at the 98th percentile nationally.
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 $374/year saved (~6.1-year payback). Topping up the attic pays for itself here.
Getting it done in Eddy County
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Eddy County's estimated $2,562/year on the line.
