Nacogdoches County, TX Insulation Payback
Attic insulation payback for Nacogdoches County, TX
Nacogdoches County, Texas is zone 3 under DOE's climate map (Hot-Humid), which means long, muggy summers and mild winters, where cooling dominates the energy bill. An uninsulated attic there should be built up to R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $989 a year — payback in roughly 2.9 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Nacogdoches County
Of that, about $587/year comes from reduced heating and $402/year from reduced cooling load through the ceiling. Nacogdoches County beats 16% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 690 counties DOE places in zone 3, Nacogdoches County ranks 491st. Against Texas's own average of $1,035/year, Nacogdoches County runs 4% below that.
Nacogdoches County's actual weather, not a national average
NOAA's NACOGDOCHES, TX US station, 1.4 miles from Nacogdoches County, supplies the 2,214 HDD and 2,521 CDD this estimate runs on. That combined heating-and-cooling load ranks Nacogdoches County 2595th nationally by total degree days — the 18th percentile. DOE also classifies Nacogdoches County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $133/year saved — roughly 12.2 years to break even. It is close - the payback only just fits a reasonable timeframe.
Quotes and materials for this job
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Nacogdoches County job, not a quote. Expect at least a $600 minimum charge from most contractors.
