Attach or tie the items to the slats or bars of your air vent to keep them secure. As you arrange these decorations, make sure that you’re not covering the vent completely.

Closing the vents doesn’t do it any favors. In fact, instead of helping the air conditioner cool less, closed registers force the same amount of air through other ducts. This builds pressure in the system and makes your HVAC system work harder to distribute the air where you need it.

Because hot air rises and cold air falls, you need to adjust your return vents with the seasons. In the summer, your lower vents should be closed and your upper vents should be open. In the winter, your upper vents should be closed and your lower vents should be open.

Closing one or two heater vents in a forced-air system is usually acceptable, as long as it’s less than 40 percent of the vents in the home, or two vents out of every five. Closing too many vents puts stress on the heating system and changes the air pressure, which may increase hot air leaks in the ducts.

Covering the floor registers in your home is potentially dangerous if you cover them when using the heating or cooling system. The air pushes through the grates, but the covers block the air from escaping. When you turn the heat up, you push more air through, which raises your heating bill.

Placing furniture in front of a forced-air heat register is certainly not a fire hazard. But if, for example, you put a bed or dresser completely over it, it will make the room less comfortable since it will restrict the air movement.

While it is a myth that air return grilles are required in each and every room in the house, it is definitely necessary to have more than one of these grilles installed at strategic places in the house. The most important place to have these would be the bedroom.

Today, it is recommended to have one or multiple air vents in each room of your home or business to optimize air flow and reduce the cost of energy spent on cooling your home or office.

Moisture Control

Static vents, positioned throughout older homes, controlled moisture. In some older homes, wall air vents helped remove moisture build-up between exterior and interior walls. This prevented mold from growing prior to the invention of sealants.

Each bedroom needs either: A return air grille ducted back to the furnace; A through-the-wall transfer grille connecting the bedroom and the adjacent hallway; or. A crossover duct (a jumper duct) connecting a ceiling grille in the bedroom with a ceiling grille in the hallway.
