Curry County, NM Insulation Payback
Attic insulation payback for Curry County, NM
DOE classifies Curry County as climate zone 4, mixed-dry — dry heat in summer giving way to a properly cold winter. Its recommended attic R-value for bare joists is 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 $1,325 a year — payback in roughly 2.6 years.
Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,129/year comes from reduced heating and $197/year from reduced cooling load through the ceiling. Curry County beats 40% of the counties in this 3,171-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Curry County ranks 536th. Against New Mexico's own average of $1,423/year, Curry County runs 7% below that.
Where these numbers come from
Curry County's climate figures — 4,221 heating and 1,225 cooling degree days a year — are read from Clovis 13 N, NM US, 7.6 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Curry County sits at the 38th percentile nationally. DOE also classifies Curry County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
If Curry 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 $193/year — payback about 11.8 years. It is close - the payback only just fits a reasonable timeframe.
Next steps for a Curry County attic
Get quotes from at least two local contractors before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth checking upfront given Curry County's estimated $1,325/year on the line.
