Falls County, TX Insulation Payback
Attic insulation payback for Falls County, TX
Falls County, Texas is zone 2 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. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-49 runs an estimated $2,820, and saves about $996 a year in heating and cooling — a payback around 2.8 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Falls County
Of that, about $609/year comes from reduced heating and $387/year from reduced cooling load through the ceiling. Falls County beats 17% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 233 counties DOE places in zone 2, Falls County ranks 6th. Against Texas's own average of $1,035/year, Falls County runs 4% below that.
The climate data behind this
NOAA's MARLIN, TX US station, 5 miles from Falls County, supplies the 2,295 HDD and 2,429 CDD this estimate runs on. That combined heating-and-cooling load ranks Falls County 2603rd nationally by total degree days — the 18th percentile. DOE also classifies Falls 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 $134/year saved — roughly 12.1 years to break even. It is close - the payback only just fits a reasonable timeframe.
Quotes and materials for this job
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $2,820 figure above as a planning number for Falls County, not a bid - contractors typically charge a $600 minimum regardless of job size.
