Hi, My air conditioner doesn’t keep the house cool enough in the summer. I live in SW Florida and the house was built in the 80’s. The existing blown in insulation has matted down. I’m about to get a new roof. I’m hoping that if I seal the attic cracks plus add inslulation it may solve my problem. I’ve come across many options and not sure which/what to do, they include which insulation should I use, fiberglass or foam on the floor, should I put a couple of inches rigid foam insulation between the roof and the plywood and insulation on the inside ceiling of the roof between the rafters? Should I cool the attic or replace the air conditioner? Help, there’s so many options.
