Conventional air conditioners follow a similar four-step method as portable air conditioners. They draw warm air from the inside, run it through their system and cool down the air, return the cooler air to the room, and then exhaust the warm air outside. Now, if you don’t vent the warm air outside, you’ll be venting the air inside the room. Hence, back to square one.
There are many portable air conditioner venting options. Most people prefer using their windows to vent that hot air out. But what happens when you don’t have a window? Your search for how to vent the AC without a window ends here. Out of the many options out there, this article will talk about venting the hot air through a wall.
Venting Through a Wall
This option is usually the last option for almost everyone using a portable air conditioner. The reason is, it’s a permanent course of action. You can’t go back from this. So, before you really decide, give it some thought. Still, want to continue? Read on then.
On a domestic property, making an opening for a vent is very straightforward, however, you must be cautious of wiring, plumbing, and studs. While it seems self-evident, it’s a good thing to think about what’s on the outside of your wall as well as what’s on the inside. And that is exactly why you should always think about placement first.
To drill a hole in your wall, you’ll need the appropriate equipment, as it’s tough to undo any mistakes you make. The diameter of the air conditioner’s hose pipe will determine the size to drill.
You should also think about how often you’ll utilize the opening to vent the portable air conditioner. If you have a power drill and you’re into DIYs, then you can drill the wall by yourself.
Necessaries Accessories to Install AC through Wall
You will need some equipment to mark the dimensions and cut the wall. They are given below:

The Installation Process
This is the main part. Read this part very carefully and follow through with every step properly.

- Normally you would have to set a depth limit so that you don’t drill too much. But the point of drilling now is to make a hole in the wall so you don’t have to worry about setting a limiter.
- Now take a firm stance, hold the drill perpendicularly against the wall and start drilling.
- Remember to drill the four points first. It would make drilling the rest of the part quite easy for you.
- Every time you drill some part, make sure to use the vacuum to clear up the dust and dirt.
- Once you are drilling the hole through your wall, make sure it’s securely sealed to keep insects, dirt, and other irritants out. Now is the time for you to apply your caulk. The best caulk to use the silicone. Simply cut the tip of the hose at a 45° angle, insert it inside the caulk gun, and apply it to the wall surrounding it.
It’s no secret that venting an air conditioner through a brick or stone wall is difficult. You must be mindful of your wall’s wiring and plumbing. Consider hiring an expert if you’re not too confident with yourself.
Venting into the Garage
You must think about where you want to drill in the wall. An external wall that can expel air directly outside should be your first choice. But if you are intending on venting the hot air into your garage then you should think over it first.
Check the ventilation of your garage. If enough air passes through your garage then you can vent the air conditioner into the garage. Without proper airflow, your garage will become an oven.
Things to Be Careful of
You must locate the safest drilling location whether you’re drilling a stone, brick, drywall, or wood wall. Or else, you risk weakening the structure especially if you are drilling the supporting beams or studs.
Examining the architectural layout of the structure is the best approach to locate a safe drilling location.
Make sure you pick the proper wall for venting before you start the drill. For example, reinforced steel walls are a poor choice since only an expert can drill through them. Do not opt for thicker walls. A portable AC can be vented via a thin wall composed of low-density cement in the best case for a room with no windows.
Why Vent through a Wall
A portable air conditioner’s purpose is cooling a room, however, in order to do just that, it must remove hot air. The warm air will stay stuck inside the room if the AC unit is not ventilated outdoors or into another room. Not only will this prevent your room from cooled down, but it will also make it warmer.
It’s also vital to vent a portable air conditioner since it absorbs moisture in the air. The colder space feels, the less humid it is. If you do not vent your portable air conditioner, moisture will build up and negate the air conditioner’s cooling effect. You can see that venting is a crucial element of remaining cool and keeping your air conditioner running efficiently.
