Quay County, NM Insulation Payback
Quay County, NM: what topping up your attic actually costs
DOE classifies Quay County as climate zone 4, mixed-dry — a wide swing between a hot dry summer and a 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 $1,295 a year — payback in roughly 2.7 years. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $1,023/year heating, $272/year cooling. Out of every 100 US counties tracked here, Quay County's savings potential beats roughly 38 of them. Within zone 4 specifically, it ranks 592nd of 825 counties by estimated savings. New Mexico averages $1,423/year across the counties tracked here; Quay County comes in 9% lower.
Quay County's actual weather, not a national average
NOAA's TUCUMCARI MUNI AP, NM US station, 6.1 miles from Quay County, supplies the 3,827 HDD and 1,694 CDD this estimate runs on. Combined heating and cooling load puts Quay County in the 40th percentile of this 3,162-county dataset. Quay County falls in DOE's moisture regime B (dry), a detail that affects vapor-barrier recommendations more than the R-value target itself.
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 $189/year saved (~12.1-year payback). This one is a genuine toss-up, not a clear yes.
