Considerations When Covering or Redirecting Active Vents April 21 2016
We're seeing the spike in orders that usually come with the start of Cooling Season (that's what we call it, but it equates to late spring - early fall). Many of these orders are to cover, reduce or redirect the air coming from active Central A/C cooling vents in rooms or areas that are too cold. This can be be done with some considerations and caution - these are not based on fact, just common sense and you may want to check with your HVAC installer before doing any of this:
- Don't completely cover more than 10% of your active vents (those with air coming out when the system is on). Why? HVAC systems are designed for a certain amount of airflow/CFMs through the system and limiting this airflow can damage a system by causing condensation on the coils and/or overworking the blower motor.
- VentSTOP can be used to redirect or limit the amount of air coming from a given vent. Because of its design, you can pull back a side or a corner of the VentSTOP cover to redirect and/or limit the airflow to cold areas, or to prevent air from blowing right on you or your family. (Consider the point above - too much limitation/reduction of airflow across your HVAC system can have negative effects.)
- If you're covering active heating vents, the heat may weaken the adhesive on the Velcro.
Please let us know if you have any questions and remember to #ventresponsibly!

Winterizing Central Air Conditioning Vents - An Important Step to Save Energy & Money November 03 2014
That autumn crispness has returned! Time to winterize your home and make it as efficient as possible for the coming cold winter months.
One of the simplest, most beneficial - yet most overlooked - winterizing steps, is to cover ALL of your central air conditioning AC vents (or registers), large return vents and even your whole-house fan shutters and louvers. Why? They are gaping holes in your ceilings, walls and floors for heat to escape and cool drafts to enter your home.
Most vents are in the ceiling and we all know that heat rises - if there's nothing to seal and insulate your vents, your expensive heat will escape right into the duct work. Then, that warm air will cool in the ducts and re-enter your home through those same vents. Not only are your vents allowing heat to escape, they're also allowing cool drafts into your home! This is terribly inefficient and uncomfortable.
Even if you "close" your vents - that does almost nothing to prevent heat loss and drafts, because the built-in louvers in your vents are far from air tight. With VentSTOP, each vent cover is a layer of insulation with a radiant barrier, to keep warm air in your home - and out of your ducts. VentSTOP is the most effective way to close your all of your vents this winter and every winter. And VentSTOP vent covers are available in essentially EVERY size!
