AC winter prep

What do you folks do to keep cold air from entering through AC in cold conditions? I took inside cover and mesh screen out and I van see daylight. Covering outside will help but plastic doesn’t have great R value! Thanks

The ACs are a closed circuit - they recirculate inside air only. If properly installed, you shouldn't have to do anything. If you can see daylight, there's something wrong.

The track system is know doubt closed I think, where I see daylight is when I take AC shroud of sealing and remove dust screen. You can see the outside vents or shroud. I just think it would be a great place for heat loss. I believe once air gets int to the ducting everything is closed. I will look closer again!
