Crawford County, KS Insulation Payback
Is attic insulation worth it in Crawford County, KS?
Crawford County sits in IECC climate zone 4 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $1,465 a year in heating and cooling — a payback around 2.4 years. Few home upgrades pay back that quickly.
The breakdown behind the number
Heating accounts for about $1,218/year of that and cooling about $247/year — Crawford County needs both. Nationally, Crawford County ranks in the 50th percentile for insulation savings potential. Compared only against its own climate zone, Crawford County places 246th out of 825. Against Kansas's own average of $1,594/year, Crawford County runs 8% below that.
Crawford County's actual weather, not a national average
Crawford County's climate figures — 4,555 heating and 1,539 cooling degree days a year — are read from GIRARD, KS US, 0.8 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Crawford County 1462nd nationally by total degree days — the 54th 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.
The smaller top-up scenario
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 $214/year saved (~10.7-year payback). Whether that is worth it depends on how long you plan to stay.
Getting it done in Crawford County
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 Crawford County, not a bid - contractors typically charge a $600 minimum regardless of job size.
