Is your upstairs unbearably hot even when the AC runs nonstop? That's one of the clearest signs your attic needs more insulation โ and in Northeast Arkansas, where July temps push 95ยฐF+ with humidity to match, a under-insulated attic can spike cooling costs by 20โ30% or more.
The most obvious red flag is uneven temperatures between floors. If the second floor or bonus room is 5โ8ยฐF hotter than the main level, heat is radiating straight through a thin or degraded insulation layer. Older homes in the Jonesboro and Trumann area often have just 3โ4 inches of original blown fiberglass, which lands around R-11 to R-15 โ well below the IRC R402.1.2 minimum of R-49 for Climate Zone 3.
Check your energy bills next. A June or July bill that jumps 15โ25% compared to the same month last year โ with no change in habits โ is a strong signal. Your HVAC is compensating for heat gain the attic insulation should be blocking.
Finally, go up there and look. Insulation that's settled, moisture-stained, or thin enough that you can see the joists clearly is doing almost nothing. Blown-in cellulose or fiberglass to a full R-49 runs roughly $1.20โ$1.80 per square foot installed โ usually a $600โ$1,200 job for a typical 1,000 SF attic โ and most homeowners see payback in 2โ4 cooling seasons.
