Edwards County, KS Insulation Payback
Attic insulation payback for Edwards County, KS
DOE classifies Edwards County as climate zone 4, mixed-humid — a genuine mix of cold winters and humid summers, with neither one dominating the bill. Its recommended attic R-value for bare joists is 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 $1,542 a year — payback in roughly 2.3 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Edwards County
Of that, about $1,308/year comes from reduced heating and $233/year from reduced cooling load through the ceiling. Edwards County beats 56% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Edwards County ranks 111th. Against Kansas's own average of $1,594/year, Edwards County runs 3% below that.
Where these numbers come from
The heating and cooling degree days behind this estimate — 4,893 HDD and 1,452 CDD (base 65°F, 1991-2020 normals) — come from KINSLEY 2E, KS US, the nearest NOAA station with published normals, 4.5 miles from Edwards County's center. By total degree days, Edwards County sits at the 59th percentile nationally. DOE also classifies Edwards County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
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 $225/year saved — roughly 10.1 years to break even. It is close - the payback only just fits a reasonable timeframe.
Getting it done in Edwards County
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Edwards County's estimated $1,542/year on the line.
