What do folks use to seal the space between the rear of the AC and the inside of the grille (so that the exhaust goes outside the box)?
I am using the Frost King HD5 Heat Deflector purchased on Amazon for $3.75, works good. A little hot glue and done.
@rcarlson1957...current [email protected] owner...be careful with putting your deflector pointing downwards..condensation can occur and leave wet fabric below...in a [email protected] that's our bed! keep an eye on it..
Cracking the vent and a window will improve air circulation in the TaB. Maybe use a small fan, too. Try deflecting it with cardboard and see if it makes a difference.
