Bedroom ac condensation when ceiling grates are in place

Hello all,
we have a 2014 Sanibel with a front ac unit. when we use the ac with the ceiling grates in place we get condensation on the bedroom ceiling. we thought we had a leak in the roof and had that checked . the ac unit was run for 2 days without the grates and filters in place with no condensation. filters were replaced and grates placed back up. we woke this am to find condensation on the ceiling once again. is it safe for the ac unit to use the grates without the filters in place? has anyone had a issue like this that they have fixed? thank you in advance or any help.

This happens when you are in a area with high humidity and you have all ceiling vents closed. Open a top vent in the bathroom or other to get more air flow and it should stop the condensation from the AC vent.
Never seal your rig totally when on AC or heat. If you do you will build up internal moisture that will show up on the inside of your windows in the morning.
Hope this helps.

We had this happen before. I usually switch the fan from auto to on. By doing this the fan runs constant even after the a/c kicked off. It made the problem go away for us.
