Taylor County, FL Insulation Payback
Taylor County, FL: what topping up your attic actually costs
DOE classifies Taylor County as climate zone 2, hot-humid — humid heat for much of the year, with cooling running far more than heating ever does. Its recommended attic R-value for bare joists is 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 $778 a year — payback in roughly 3.6 years. The math clears comfortably within a normal ownership horizon.
Where the savings come from
The estimated savings split roughly $343/year heating, $436/year cooling. Out of every 100 US counties tracked here, Taylor County's savings potential beats roughly 4 of them. Within zone 2 specifically, it ranks 184th of 233 counties by estimated savings. Florida averages $743/year across the counties tracked here; Taylor County comes in 5% higher.
Taylor County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 1,292 HDD and 2,733 CDD (base 65°F, 1991-2020 normals) — come from PERRY FOLEY AP, FL US, the nearest NOAA station with published normals, 8.2 miles from Taylor County's center. By total degree days, Taylor County sits at the 3th percentile nationally. Taylor County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
The smaller top-up scenario
If Taylor 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 $105/year — payback about 15.5 years. This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-49 is the target here specifically.
