This is a common mistake homeowners make with their HVAC systems during the summer. When the air conditioner is running, the blower fan sends the cooled air into the ducts so the air travels to all the room vents. Because the vent registers usually have shutters on them that can be moved to change the direction air blows into rooms, people think they can shutter the vent completely, thus stopping the AC from cooling the room.
But does this save money? No! In fact, it can cause serious problems leading to the need for AC repair in Van Nuys, CA. Please always keep the vents open, and don’t obstruct them with furniture or anything else.
