Crawford County, MI Insulation Payback
Is attic insulation worth it in Crawford County, MI?
Crawford County, Michigan is zone 6 under DOE's climate map (Cold), which means a real winter that drives most of the annual energy bill here. An uninsulated attic there should be built 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 $2,257 a year in heating and cooling — a payback around 1.5 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Crawford County
Heating accounts for about $2,200/year of that and cooling about $57/year — Crawford County needs both. Nationally, Crawford County ranks in the 92th percentile for insulation savings potential. Compared only against its own climate zone, Crawford County places 132nd out of 459. Against Michigan's own average of $2,064/year, Crawford County runs 9% above that.
The climate data behind this
Crawford County's climate figures — 8,228 heating and 353 cooling degree days a year — are read from GRAYLING, MI US, 4.7 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Crawford County in the 92th 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.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $329/year saved — roughly 6.9 years to break even. The math clears comfortably within a normal ownership horizon.
