Cheboygan County, MI Insulation Payback
Is attic insulation worth it in Cheboygan County, MI?
Cheboygan 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. 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 1.6 years at an estimated $2,195/year saved. Few home upgrades pay back that quickly.
The breakdown behind the number
Heating accounts for about $2,145/year of that and cooling about $49/year — Cheboygan County needs both. Nationally, Cheboygan County ranks in the 90th percentile for insulation savings potential. Compared only against its own climate zone, Cheboygan County places 190th out of 459. Against Michigan's own average of $2,064/year, Cheboygan County runs 6% above that.
Where these numbers come from
The heating and cooling degree days behind this estimate — 8,024 HDD and 308 CDD (base 65°F, 1991-2020 normals) — come from CHEBOYGAN, MI US, the nearest NOAA station with published normals, 12.3 miles from Cheboygan County's center. By total degree days, Cheboygan County sits at the 89th percentile nationally. 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 $320/year saved (~7.1-year payback). The math clears comfortably within a normal ownership horizon.
Quotes and materials for this job
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 Cheboygan County, not a bid - contractors typically charge a $600 minimum regardless of job size.
