Aleutians West Census Area, AK Insulation Payback
Aleutians West Census Area attic insulation, by the numbers
Aleutians West Census Area, Alaska is zone 7 under DOE's climate map (Very Cold), which means a climate where the heating season stretches across most of the year. An uninsulated attic there should be built 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 $2,755 a year in heating and cooling — a payback around 1.3 years. Topping up the attic pays for itself fast here.
Where the savings come from
Cooling barely factors in here; essentially the full $2,755/year is heating savings. By estimated insulation savings, Aleutians West Census Area lands in the 99th percentile nationally. Zone 7 alone covers 120 counties in this dataset, and Aleutians West Census Area comes in 15th by savings. Alaska averages $2,854/year across the counties tracked here; Aleutians West Census Area comes in 3% lower.
Aleutians West Census Area's actual weather, not a national average
NOAA's ST GEORGE ISLAND AP, AK US station, 540.9 miles from Aleutians West Census Area, supplies the 10,305 HDD and 0 CDD this estimate runs on. By total degree days, Aleutians West Census Area sits at the 99th percentile nationally.
Already have some insulation?
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 $402/year saved (~5.7-year payback). Worth doing on the numbers alone.
Getting it done in Aleutians West Census Area
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 Aleutians West Census Area job, not a quote. Expect at least a $600 minimum charge from most contractors.
