Midland County, MI Insulation Payback
Midland County attic insulation, by the numbers
Midland County, Michigan is zone 5 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. 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 $1,919 a year in heating and cooling — a payback around 1.8 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Midland County
Split it out and it's roughly $1,817 a year on the heating side, $101 on cooling. By estimated insulation savings, Midland County lands in the 78th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Midland County comes in 124th by savings. Michigan averages $2,064/year across the counties tracked here; Midland County comes in 7% lower.
Where these numbers come from
NOAA's MIDLAND, MI US station, 9.3 miles from Midland County, supplies the 6,797 HDD and 630 CDD this estimate runs on. Combined heating and cooling load puts Midland County in the 78th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Midland County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
If Midland County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $280/year — payback about 8.1 years. Call this borderline rather than a clear win.
Next steps for a Midland 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 Midland County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Midland County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
