Mora County, NM Insulation Payback
Attic insulation payback for Mora County, NM
Mora County, New Mexico is zone 5 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. An uninsulated attic there should be built 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 $1,577 a year — payback in roughly 2.2 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Mora County
Of that, about $1,520/year comes from reduced heating and $58/year from reduced cooling load through the ceiling. Mora County beats 58% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Mora County ranks 669th. Against New Mexico's own average of $1,423/year, Mora County runs 11% above that.
Mora County's actual weather, not a national average
Mora County's climate figures — 5,683 heating and 358 cooling degree days a year — are read from VALMORA, NM US, 11.5 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Mora County 1502nd nationally by total degree days — the 53th percentile. DOE also classifies Mora County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
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 $230/year saved — roughly 9.9 years to break even. It is close - the payback only just fits a reasonable timeframe.
Next steps for a Mora County attic
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Mora County, not a bid - contractors typically charge a $600 minimum regardless of job size.
