^+1 betting on a evap fin clogging airflow. I use BG products everyday.. Once you either fix the problem. Avoid running the a/c on fresh air, run it on recirculate. That way your not sucking in that hot humid florida air. Once it starts getting on the evap, heating-cooling-heating-cooling, it creates mold which stinks like shit, and tends to cause the buildup on the evap.
