$720–$960/yr
Bringing a 2,000 sq ft Florida home up to R-38 typically cuts cooling load and pays for itself in about 2.6–3.5 years.
Estimates are for planning only and based on typical Central Florida homes and 2026 pricing for blown-in fiberglass. Your exact price depends on attic access, existing insulation condition, and whether removal is needed — confirmed free during your inspection.
In Florida, air conditioning is the biggest driver of your electric bill, and an under-insulated attic is the number-one reason it runs constantly. This calculator estimates your yearly AC savings from upgrading the attic to R-38.
The bigger the gap between your current insulation and R-38 — and the hotter your attic gets — the more you stand to save.
What goes into this estimate
Cooling load. Larger homes and hotter attics mean more potential savings.
Insulation gap. The distance from your current R-value to R-38 drives the savings.
Estimated savings. Derived from attic footprint and typical Florida cooling costs.
Frequently asked questions
How much can attic insulation lower my AC bill in Florida?
Upgrading an under-insulated Florida attic to R-38 commonly saves a few hundred dollars a year in cooling costs, depending on home size and current insulation.
