Finney County, KS Insulation Payback
Finney County, KS: what topping up your attic actually costs
DOE classifies Finney County as climate zone 4, mixed-humid — heating load in winter and cooling load in summer, both worth taking seriously here. Its recommended attic R-value for bare joists is 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 $1,611 a year in heating and cooling — a payback around 2.2 years. That's about as fast as attic paybacks get.
Heating vs. cooling in Finney County
The estimated savings split roughly $1,387/year heating, $223/year cooling. Out of every 100 US counties tracked here, Finney County's savings potential beats roughly 60 of them. Within zone 4 specifically, it ranks 42nd of 825 counties by estimated savings. Kansas averages $1,594/year across the counties tracked here; Finney County comes in 1% higher.
Where these numbers come from
NOAA's GARDEN CITY EXP STN, KS US station, 5.6 miles from Finney County, supplies the 5,188 HDD and 1,391 CDD this estimate runs on. By total degree days, Finney County sits at the 63th percentile nationally. Finney County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $235/year saved — roughly 9.7 years to break even. This one is a genuine toss-up, not a clear yes.
