Tyler County, TX Insulation Payback
Attic insulation payback for Tyler County, TX
Tyler County sits in IECC climate zone 2 (Hot-Humid) — long, muggy summers and mild winters, where cooling dominates the energy bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. Going from R-2 to the recommended R-49 costs roughly $2,820 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 3.2 years at an estimated $892/year saved. Worth doing on the numbers alone.
Where the savings come from
Of that, about $508/year comes from reduced heating and $384/year from reduced cooling load through the ceiling. Tyler County beats 9% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 233 counties DOE places in zone 2, Tyler County ranks 53rd. Against Texas's own average of $1,035/year, Tyler County runs 14% below that.
Where these numbers come from
The heating and cooling degree days behind this estimate — 1,916 HDD and 2,410 CDD (base 65°F, 1991-2020 normals) — come from TOWN BLUFF DAM, TX US, the nearest NOAA station with published normals, 11.6 miles from Tyler County's center. Combined heating and cooling load puts Tyler County in the 7th percentile of this 3,162-county dataset. DOE also classifies Tyler 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
If Tyler County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-38. That smaller top-up costs around $1,620 and saves an estimated $120/year — payback about 13.5 years. 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 Tyler County job, not a quote. Expect at least a $600 minimum charge from most contractors.
