With the high cost of heating and cooling a home, it’s understandable to think that by closing off vents in some rooms, hot air will be redirected into the rooms with open vents. Unfortunately, it doesn’t work that way. An HVAC unit (furnace, AC, or heat pump) is specifically sized to match the cubic feet of a home’s living space. No matter how many vents are open, the unit will run at the same power level. Keep reading to find out why closing vents could end up costing more than keeping them open.
The Pressure Problem
When the furnace kicks on, the blower forces hot air through the ductwork and out of the vents. When vents are closed, the air pressure builds up and increases the risk of duct leaks. Leaks in ducts result in the loss of heated or cooled air into the walls, which then leads to higher energy costs.

As a result of air vents being closed, negative air pressure is created which forces your HVAC system to work harder. This additional strain may eventually damage components of your HVAC unit which could lead to failure. While you might think that closing certain heat vents is beneficial, having uniform heat distribution helps to ensure that heat from other rooms isn’t drawn towards adjacent floors, walls, and ceilings.
