Wells County, IN Insulation Payback
Attic insulation payback for Wells County, IN
Wells County sits in IECC climate zone 5 (Cold) — a real winter that drives most of the annual energy bill here. 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 $1,782 a year — payback in roughly 2 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,653/year comes from reduced heating and $128/year from reduced cooling load through the ceiling. Wells County beats 71% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Wells County ranks 332nd. Against Indiana's own average of $1,634/year, Wells County runs 9% above that.
The climate data behind this
Wells County's climate figures — 6,184 heating and 798 cooling degree days a year — are read from BLUFFTON 6N, IN US, 6.2 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Wells County sits at the 71th percentile nationally. DOE also classifies Wells County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
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 $260/year saved (~8.8-year payback). It is close - the payback only just fits a reasonable timeframe.
Next steps for a Wells 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 Wells County job, not a quote. Expect at least a $600 minimum charge from most contractors.
