Yellow Medicine County, MN Insulation Payback
Is attic insulation worth it in Yellow Medicine County, MN?
Yellow Medicine County sits in IECC climate zone 6 (Cold) — winters that dominate the energy bill, with cooling a minor factor. 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 $2,319 a year — payback in roughly 1.5 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Yellow Medicine County
Heating accounts for about $2,231/year of that and cooling about $88/year — Yellow Medicine County needs both. Nationally, Yellow Medicine County ranks in the 94th percentile for insulation savings potential. Compared only against its own climate zone, Yellow Medicine County places 87th out of 459. Against Minnesota's own average of $2,366/year, Yellow Medicine County runs 2% below that.
Where these numbers come from
The heating and cooling degree days behind this estimate — 8,345 HDD and 546 CDD (base 65°F, 1991-2020 normals) — come from MONTEVIDEO 1SW, MN US, the nearest NOAA station with published normals, 16.1 miles from Yellow Medicine County's center. That combined heating-and-cooling load ranks Yellow Medicine County 192nd nationally by total degree days — the 94th percentile. 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.
Already have some insulation?
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 $338/year saved (~6.7-year payback). The math clears comfortably within a normal ownership horizon.
Next steps for a Yellow Medicine County attic
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Yellow Medicine County job, not a quote. Expect at least a $600 minimum charge from most contractors.
