If your Florida home feels like an oven even with the AC running constantly, the culprit is almost always your attic. During Florida's long summer months, attic temperatures can reach 150–160°F — and if your insulation is old or insufficient, that heat transfers directly into your living space.
Most Florida homes built before 2010 were insulated to R-19 or less. Today's Florida Building Code requires R-38 minimum for attics — meaning older homes are letting twice as much heat through as they should.
The fix is straightforward: blown-in fiberglass insulation to bring your attic up to R-38. Most homeowners notice a difference in comfort within days, and a measurable drop in their electric bill within the first month.
The average Florida homeowner with an under-insulated attic spends $150–$300 more per year on energy bills than necessary. Upgrading insulation typically pays for itself in 1–3 years.
