Haskell County, KS Insulation Payback
Attic insulation payback for Haskell County, KS
Haskell County, Kansas is zone 4 under DOE's climate map (Mixed-Humid), which means a genuine mix of cold winters and humid summers, with neither one dominating the bill. 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 2.4 years at an estimated $1,439/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,193/year comes from reduced heating and $246/year from reduced cooling load through the ceiling. Haskell County beats 49% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Haskell County ranks 295th. Against Kansas's own average of $1,594/year, Haskell County runs 10% below that.
Haskell County's actual weather, not a national average
NOAA's SUBLETTE 7WSW, KS US station, 9.5 miles from Haskell County, supplies the 4,463 HDD and 1,530 CDD this estimate runs on. That combined heating-and-cooling load ranks Haskell County 1531st nationally by total degree days — the 52th percentile. DOE also classifies Haskell 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
If Haskell 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 $210/year — payback about 10.9 years. It is close - the payback only just fits a reasonable timeframe.
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 Haskell County, not a bid - contractors typically charge a $600 minimum regardless of job size.
More on how this was built
Nothing here is a guess: the methodology guide names the DOE climate map and NOAA station data behind every number on this page. See the DIY vs. contractor guide for whether a job this size is realistic to do yourself.
