Comanche County, KS Insulation Payback
Is attic insulation worth it in Comanche County, KS?
Comanche County sits in IECC climate zone 4 (Mixed-Humid) — real heating and real cooling seasons both, roughly balanced across the year. 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 $1,360 a year — payback in roughly 2.6 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Comanche County
Heating accounts for about $1,054/year of that and cooling about $306/year — Comanche County needs both. Nationally, Comanche County ranks in the 43th percentile for insulation savings potential. Compared only against its own climate zone, Comanche County places 461st out of 825. Against Kansas's own average of $1,594/year, Comanche County runs 15% below that.
The climate data behind this
Comanche County's climate figures — 3,942 heating and 1,905 cooling degree days a year — are read from COLDWATER, KS US, 7.6 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Comanche County sits at the 48th percentile nationally. 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.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $198/year saved — roughly 11.5 years to break even. Whether that is worth it depends on how long you plan to stay.
Quotes and materials for this job
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 Comanche County job, not a quote. Expect at least a $600 minimum charge from most contractors.
