**1. Your home is uncomfortably hot despite running the AC.** If certain rooms — especially those on upper floors or under the roof — stay hot even when the AC is on, insufficient attic insulation is the most common cause.
**2. Your electric bills are higher than neighbors with similar homes.** Under-insulated attics make your AC work significantly harder. If your bills seem out of proportion to your home size or usage, have your attic checked.
**3. Your attic insulation is visibly old, matted, or shallow.** Insulation settles and degrades over time. If you can see your attic floor joists through the insulation, you are well below R-38 and due for an upgrade.
**4. Your home was built before 2010.** Older Florida building codes allowed lower insulation values. Most homes built before 2010 are insulated to R-11 or R-19 — less than half the current code requirement.
**5. You notice temperature differences between floors.** Hot upper floors while lower floors are cool is a classic sign that heat is conducting through an under-insulated attic ceiling.
