  • Common Questions


    Is the product going to stay in place on the ceiling vent?


    Yes. I put the deflector on the vent above my recliner and it completely diverted the air.


    I don't know how to be sure this vent cover won't melt from the heat.


    People are having a problem with it being attached to a wall heater vent which has the heating core right at the vent, and the people answering that they haven't had a problem probably have central air which will not produce the high temperatures to melt it.


    Is it possible that this would work on a standard air conditioner, like the ones you'd put in a window or wall?


    I attached one side of the velcro to the sides of the deflector and other strip of the velcro to the AC unit on both sides of the vent.


    Is it possible to change the flow for heat vs cold air with this deflecter?


    I use mine on a floor bent that has a shelf over it so that the air comes out and I don't do anything different for heat vs ac.


    Can you tell me what the width of the vent is, the short side, front to back?


    The vent has a short side and a long side. The depth of the top of the product is three inches.
