Below, you will get the answer to this question and a variety of other tips that can help you save money during the hot summer months.
Can Closing HVAC Vents In Unused Rooms Save Money?
If you close the vents in unused rooms, it will not cause your heating and cooling system to work less. Also, closing the vents won’t help you save money on your energy costs. Instead, it will just cause pressure to build up inside the ducts.
This pressure can result in problems that require expensive repairs. The problem that closing the vents will generate depends on the type of blower motor that your unit has. A few common A/C issues include:
- Increased energy use
- Frozen air conditioner coil
- Duct leakage
- A dead compressor
- Low airflow in the ducts
To learn more about closing the HVAC vents in your unused rooms, read on.
Types Of Blower Motors
For the cool air to spread around the home, your HVAC system relies on the blower motor. When the blower is working correctly, it will pull the warm air from the house and release it through the return ducts. It will also push the cool air around the home via the supply ducts. There are two types of blower motors, electronically commutated motor (ECM) and permanent split capacitor blowers (PSC).
The ECM blower can change speeds depending on how hard it needs to work. A PCS motor will always blow air out at a fixed rate. Therefore, an ECM motor is highly efficient, and the PCS motor is not as energy efficient.
How Closing HVAC Vents Affects The Blower Motor Performance
Both types of blower motors work by pushing the air through the home against the pressure difference. This pressure difference is often 0.5 inches of water column (IWC). There are, however, specific factors that can cause the difference in pressure to increase substantially.
For example, narrow supply ducts and dirty, dusty air filters can affect the amount of pressure. Closing off the HVAC vents in the unused rooms will also cause this to happen. With the increase of force, the ECM motor will need to work harder, increasing your cooling costs.
A PSC blower will always blow at a fixed rate. If there is too much pressure in the ducts, it won’t work any harder. In fact, an increase in pressure causes it to slow down, and you will get less air from the open AC vents. After some time, the pressure buildup can cause the evaporator coils in the system to freeze over, leading to severe damage to the compressor. A compressor is very expensive to fix.
Increased Duct Leakage
According to Energy Star and reputable local HVAC contractors, the average home loses between 20 and 30 percent of its cold air when the ducts leak. Therefore, there is a good chance that your home is already wasting cool air. If you add extra pressure, it can make the leak even worse. If your AC unit has to work harder to keep your home cool due to faulty ductwork, it will cost you much more than you should be paying on your home cooling costs.
Think About Installing A Ductless Air Conditioner
One way to increase the efficiency of your air conditioner is by supplementing it with a ductless air conditioning system. Ductless AC units are highly efficient and require a minimal amount of energy to keep a room or zone comfortable. Many homeowners install these types of units in their homes to keep areas that are frequently used at a comfortable temperature. Also, by supplementing their central unit with a ductless system, they can enjoy lower cooling costs without sacrificing their comfort.

You cannot save money by merely closing the vents in the unused rooms. Doing this won’t change how your blower motor performs. In fact, it can damage it. If you close the vents, it will result in a buildup of pressure. The blower motors work at a specific pressure difference. Depending on the type of blower your system has, you could have reduced air flow, indoor comfort problems, a frozen coil, a crack in the heat exchanger, and even a dead compressor.
