US Department of Energy says Florida homes need 10 to 16 inches or R-30 to R-49 of insulation. Most central Florida homes have less than 6 inches. REMEMBER: code is the minimum amount the builder can put in. It's not your fault your attic is inefficient, builders hire the cheapest contractors to do the minimum. They don't insulate garage or lanai because it's not required by code. You need more insulation to protect your home and ducts from heat and rodents, preventing holes and wasted A/C
WARNING: Other insulation companies only add about 10 bags in a 1500 sf home and are gone in 30 minutes, no inspection no repairs. They won't even tell you how many bags they are going to put in. For about the same cost we install 20 bags and we inspect your ducts work for leaks and fix minor damage. It takes about 3-6 hours and you'll see and feel the difference immediately.
