Avoid closing more than 10 percent of your vents.Ĭlosing too many vents creates a pressure imbalance in the duct system, which can damage your HVAC system’s components. These flat sheets of rubber are magnetized to hold them in place over vents. Another is to apply magnetic vent covers. One is to use vent deflectors with hoods that can be lowered over the vent to block airflow. ![]() ![]() To direct airflow away from unused rooms and toward rooms that need more heating and cooling, you have several options. If you have plastic or wooden covers, choose models that can be secured to these. Most are fitted with magnets designed to secure them to metal vent covers. Also check that you’ll be able to install them on top of your existing vent covers. While many deflectors and extenders are expandable, not all are. These long, flat covers are placed over the existing vent cover to guide air out from under the item of furniture so the air can flow out into the room.īefore you buy a vent deflector or extender, measure your vents to determine the size of cover you’ll need. In these cases, a vent extender can help. There may also be times when a vent is blocked by furniture, equipment or another item. Directing airflow away from walls and furniture, and toward the center of the room to provide more even temperatures.Directing airflow away from curtains, plants, and equipment to prevent disruptive breezes.Directing airflow away from work areas to prevent uncomfortable drafts.They’re available for both floor vents and wall vents. These plastic covers are placed over the vents to guide airflow in a particular direction. If your goal is to direct the airflow more precisely, vent deflectors are a better choice. Decorative metal covers with elaborate patterns, rather than simple slats, also help with redirecting vents to provide a less concentrated airflow. Vent covers made of wood have thicker slats than metal or plastic models, so they break up airflow more effectively. If the only result you expect from redirecting vents is somewhat softer airflow to prevent drafts, you can achieve this with a different type of vent cover. ![]() In addition, the covers help diffuse the air coming out of the ducts so you aren’t blasted with a single, powerful stream of air. These covers are designed to keep foreign objects from falling into the vent and being blown into the duct system where they could damage your HVAC system’s components. Most likely, the vents in your building are covered by standard vent covers in the form of metal or plastic grilles that are screwed in on top of the vents or air registers. By directing conditioned air exactly where it’s needed most, you’ll be able to provide comfortable temperatures in any kind of weather. Redirecting vents is one way you can fine-tune your system to do that. Thanks to the Pennsylvania and Maryland area’s hot, humid summers and snowy winters, you’re bound to get some complaints if your building’s heating and cooling system isn’t optimized to keep everyone comfortable.
