How To Vent A Portable Air Conditioner Without A Window

Sometimes the heat isn’t bearable, and air conditioning is the only solution to the problem. The struggle becomes apparent when you have no window or air conditioning in your house. The solution is actually quite simple.

Cut a 5” hole into the wall with a jigsaw on both the interior and exterior sides of the wall. Attach a hose to the air conditioner, feed it through both holes, secure it with a ring and 4 screws. Install the exhaust hood, screw it in place, and apply sealant around the hedges to hold it in place.    

This method does not require any advanced skills. In order to be successful, you only need to measure twice before cutting. In this article, we will walk you through each step so that you can vent your portable air conditioner and enjoy the nice cool climate of your room.

Why Does A Portable Air Conditioner Need To Be Vented?

A portable air-conditioner needs to be vented because it extracts hot air. In order to maintain a cool temperature in the room, the hot air must go somewhere. It makes sense that it should go outside.

An air conditioner works by using a cooling agent called a refrigerant. It absorbs the heat from the air, letting the cool air return back into your room. While the air-conditioner is very effective at its job, it also makes hot air in the process.

If you did not vent the air-conditioner, it would negate the cooling factors. It is common to vent an air-conditioner through a window, wall, ceiling, or door. However, for this article, we will be focusing on how you can vent an air-conditioner through the wall.

The Importance Of Knowing The Location Of Your Studs

Before you even consider cutting open your wall, you need to know the location of your studs. It would not be good to cut a hole in the wall and find something important behind there. That would only leave you with a huge mess to clean up.

Instead, pull out your stud finder. It will detect metal joints, studs, joists, and even live wire. However, the knocking method can be used if you do not have this.

Simply knock at different locations on the wall. When the knock makes a higher pitch, there is a stud there. If you want further information on studs, check out this article here.

Steps To Venting Your Portable Air Conditioner

Make sure you have everything in order before beginning. This will make the process go a lot smoother so that you don’t have to keep stopping and acquiring materials and tools in the middle of the project.

Step 1: Gather Your Materials

Now that you know where you’re going to cut into your wall, you need to gather your materials.

For this project you are going to need a Portable AC Unit, a 5” air conditioning hose, a 5” ring, a drill, a jigsaw, screws (10), an outdoor exhaust hood, and sealant.

Once you have gathered up all these materials, you are ready to get started.

Step 2: Measure Twice And Cut Once

Start by measuring where the air-conditioning vent is located in comparison to your wall. Measure from the ground to the top of the vent. Use this number to mark the wall with a pencil.

Now that you know where the top is located, use the ring to trace a circle on the wall. When you are done, it should line up perfectly with the vent. If it does not, do this process again until it is perfect.

Once your lines are traced, you can begin cutting with your jigsaw. Do this slowly to make sure that you get the perfect cut.

Step 3: Make An Identical Hole From The Outside

Now that you have a perfect 5” hole in your wall, it’s time to make an identical one on the other side. Start by drilling a small hole through to the outside, and then head out with a jigsaw, ring, and your measurements.

Repeat the steps from earlier to trace a 5” hole, and then cut it in with a jigsaw. As before, make sure to do this slowly for perfect results. Once you are done, you should be able to look through to the inside of your house.

What About The Hose?

The hose is very important because it’s what vents all the hot air outside. To start, you should connect the hose to the air-conditioner. Do not forget to string the ring onto the hose before connecting it!

Now you must string the hose through the wall. However, do not clasp the ring in place until later. Simply let it hang loose on the hose. You can close it off at the end of the project.

Step 4: Install The Exhaust Hood

For this part, you need to head back outside. Don’t forget to bring your screws and sealant with you.

Start by screwing 4 screws into the inside of the hose to hold it in place. Follow this by applying plenty of sealant around the edges of the hose.

After this, screw the hood cover on top of the hose. Hold it in place by screwing in 6 screws. There should be designated holes for this procedure.

Make sure to apply plenty of sealant around the edges for durability. After that, you are done with the work outside! It should look nice and professional now.

Step 5: Seal The Ring Into The Wall

Head back inside to move the ring into place. It should slide in perfectly, and make the hose look more professional.

Once you have done that, the only step left is to seal it in place. Make sure to use plenty of sealant, as this will keep any air-leakage from coming into your house.

Now that you are done, the only step left is to enjoy the cool air coming out of your air-conditioning.

How Do I Keep The Elements From Getting Inside During Winter?

When you create a huge hole in your wall, you should consider the elements. They can bring in cold air when you want it the least. However, there is an easy solution to this.

From any hardware store near you, there are caps that you buy to cover the vent. This will keep the elements from getting in when the air-conditioner is not in use.

What If My Air Conditioning Leaks?

If you are concerned that your air conditioning may leak, you can always consider putting a metal pan underneath the vent. This will give it a better place to drip on to.

However, if you want a permanent fix, considering reading about air-conditioning leaks. This article goes into detail on what causes leaks, and how you can fix it.

After all, you’re a handy person. Anything can be fixed if you have the right information.

What If You Don’t Vent A Portable Air Conditioner?

If your AC unit doesn’t have a vent running to the outside then your air will remain warm due to it producing humidity. However, the less humidity, the cooler your room will be. Not venting your air conditioner pretty much defeats the purpose of having an air conditioner in the first place as it will just heat up your room and make the climate even more miserable.

Is It Dangerous If You Don’t Vent The Air Conditioner?

While it’s not dangerous if you don’t vent your air conditioner, it can run the risk of making your room even hotter. However, if you want to do this without a vent hose then you can do this in dehumidifier mode. This can help to keep the humidity at bay.

How Much Electricity Do Portable Conditioners Use?

The amount of electricity that your portable air conditioner uses depends on the size of it and its BTUs or cooling capacity. If you use a portable air conditioner, you can expect it to use about one-eighth the amount that your central air conditioner unit uses. this is because you aren’t cooling the entire house, but rather only one room.
The air conditioner won’t work as hard as your central system does since it only has that one room to keep cool. Furthermore, if you get an energy-saving type of portable air conditioner you can save even more on electricity.
