Have you ever wondered whether closing vents can save you money? This is a common question, but the answer is no. Closing vents, even in rooms that you don’t go into during the summer, will lead to problems.

You should keep your AC vents open. Closing your AC vents will increase your energy bills. It can also damage your air conditioning system. When you close AC ducts, more air-conditioned air ends up wasted through duct leaks.

Make sure all AC vents in your home are open all the time. This will not only save money but also keep your AC working optimally.

Why AC Vents Should Be Open

Keep your AC vents open all the time. If you close your AC vents, it will lead to potential problems. Examples include a damaged air conditioning system and higher energy bills. You will also not be as comfortable as you would be if you kept the vents open.

Should AC Vents be Closed in Winter?

No, you shouldn’t close your HVAC systems vents in the winter. This will make it harder for your heating system to work as it should. The system will be under more stress as it tries to heat all the rooms in your house.

When you close vents in one room, it will increase the air pressure in other parts of the system. This can create damage to the duct system. Remember that HVAC systems are designed for temperature regulation in the entire house. This design isn’t intended for having closed vents.

Closed AC Vents Increase Energy Bills

Many homeowners mistakenly believe that closing their AC vents will save them money. In fact, the opposite is true. When you close your AC vents, you end up with damage to your AC system and higher energy bills.

Also, a closed air vent can lead to more pressure within the ducts. When there is excessive pressure in the ducts, more air will be pushed out of any small leaks there may be in the ductwork. It may surprise you, but most air ducts have leaks of some kind. The average amount of air-conditioned air that homes lose is about 20 percent to 30 percent.

Should Air Vents in the Basement Be Open or Closed?

One area of your house where you might be able to close AC vents in the summer is your basement. Many people think they can close the vents on their first floor, but you shouldn’t do this. If you want to focus your cooling more on the upper floors, you can close the vents in the basement if you want to. In the basement, the furnace fan will move around cool air in the summer.

How to Open Ceiling Air Vents

Opening the air vents on your ceilings is more difficult than doing so with the air vents on walls. This is because ceiling air vents are more difficult to reach. Follow the steps below to open your ceiling air vents:

Step 1. Find a sturdy ladder or stool.

Get a ladder or stool and put it underneath the vent. Ensure the stool or ladder is in the locked position. This will stop it from collapsing. There are different types of ladders available, so get one that suits your needs.

Step 2. Step onto the stool or ladder.

Step up onto the ladder or stool. Get positioned so you can easily reach the ceiling vent you want to open.

Step 3. Find the switch on the vent or the dial.

If your ceiling vent is round or square, the dial is probably in the center. If you have a rectangular vent, the switch will probably be on the left or right-hand side. In some cases, you may have to do individual adjustment of the blades.

Step 4. Open the vent.

If you have a round or square vent, turn the dial to the right. This should open to the vent. If you have a rectangular ceiling vent, move its switch in an up or down direction for opening and closing. Choose the open option.

How to Open Wall AC Vents

AC vents located on the wall are easier to open than ceiling vents. When you want to open your AC vents, follow these steps:

Step 1. Decide on the temperature.

Make a decision about what temperature you want and adjust the temperature on the AC thermostat.

Step 2. Find your wall vents.

Locate the wall vents in your home. Go to each vent one at a time and follow these steps.

Step 3. You should start to feel cool air.

After you have turned on the AC, you should start to feel cool air.

Step 4. Check if there are any vents where you don’t feel cool air.

Check each vent in your house and make sure they are open. You should feel cool air coming out of all of them, and they should be completely open.

Step 5. Open any closed vents.

If you find any closed vents, open them. Look for the lever located outside the vent. Push this lever over to one side. Whether you feel air flowing from it or not will indicate whether you have opened or closed your vent.

Step 6. If you accidentally closed a vent, open it.

Open it by moving the lever in the direction opposite to what you did before.

Step 7. Check all the vents in your house.

Go all over your house and make sure all rooms with vents have open vents.

Vents in Window Air Conditioners

With window air conditioners, the vent is where outdoor air is able to get into the room. It is also the place through which indoor air can be released into the outdoors. If you have the vent open, outdoor air will be able to get into your room. When this happens, there is increased pressure in your space. This pushes out some of the air already indoors. If you keep the vent closed, your air conditioner will only recycle and circulate the air already in your space.

Saving Money on AC Bills

Closing vents won’t save money on your AC bill. There are other things you can do, though. One step to take in improving your home’s energy efficiency. Ways to do this may include:

  • Insulating windows with weather stripping
  • Inspecting for air leaks around doors and windows, in crawlspaces, in the attic, around plumbing, and around ductwork
  • Adding caulk to your doors and windows
  • Changing your window dressings to thermal insulating curtains

What is an Air Vent Diverter?

Air vent diverters are also called air vent deflectors. Using an air vent diverter can help you make your HVAC system more effective. An air vent diverter redirects air that comes out of the vents to create better cooling and heating. Air vent diverters are usually made of plastic and designed to fit over the vent.

Decide on how you need to redirect the air. This will help you decide whether the diverter should be adjusted upwards or downwards. Using air vent diverters to more effectively target areas of your home, you can save energy. You can also keep your HVAC system working well longer.

There are certain situations that air vent diverters are best for. These include:

  • A vent in your home is blowing air in inefficient directions, such as into an unused space or directly at furniture.
  • You want to find ways to make your house warmer or cooler without changing your thermostat settings.
  • There are often pockets of hot or cold air in your home.
  • You have considered closing air vents. You shouldn’t do this, as it will cause problems with your system and cost you more money. Use air diverters instead..
