How To Vent a Portable Air Conditioner Without a Window?

Portable air conditioners can come in very handy when it comes to cooling a windowless room. They also wick away moisture, which helps keep the room comfortable on hot, humid days. They are small, compact, easy to install and mobile, which is why they are so popular. Unfortunately, however, for a windowless space it can lead to a number of drawbacks.

Like any other air conditioner, portable units draw air from inside the room and cool it. The heat generated in the process is expelled to the outside through a “hose” or flexible tube. In a space with windows this residual hot air is expelled through the pipe through the window, in a room without windows this becomes complicated and you would have to drill holes in an exterior wall however, which is a semi-permanent solution rather than a temporary one.

In this article we have share some of the ctionable tips and way tovent a portable air conditioner without a window.

Venting through a door

There are rooms without windows, but there are no rooms without doors, right.

Every room has a door that may be used to vent a portable air conditioner. The most popular method of venting a portable air conditioner without a window is by using doors.

Of course it matters where those doors go. You can have trouble creating the necessary temperature difference for the air conditioner to work if it goes to a corridor or another room.
On the other hand, if your balcony door opens to the outside, you can immediately vent an air conditioner there.

Use a sliding door if you want to vent a portable air conditioner through a door the simplest method possible.

For sliding doors, there are kits designed expressly that let you vent the exhaust outside. They work with any machine and are really simple to use.

Vent Through The Wall

Vent the exhaust from your portable air conditioner outside if all else fails. Although it is a permanent fix for a portable cooling system, you can put a vent in the wall of your residence or place of business.

Consider how frequently you will actually use the portable air conditioner for a moment before starting to gather supplies or looking into hiring an expert. Consider positioning if you’re willing to make a rather sizable hole in your wall, then grab some tools or a phone. Here’s an excellent example of what to anticipate during a “easy” installation.

On a residential property, cutting a hole for a vent is very simple, but you still have need to be careful around wiring, plumbing, and studs. Even though it might seem obvious, it’s a good idea to take into account both the inside and outside of the wall.

Wood and drywall are both easily cut through, but brick or stone will be much more challenging.

Vent Through The Wall Ceiling

If the room where the portable AC unit will be utilised has drop ceilings, you have another choice. Not many modern residential residences have it, but older homes with high ceilings that are combined with businesses and commercial real estate frequently do.

In your home, you can usually modify an exhaust vent to work with a drop ceiling tile, but it can be more labour than it’s worth.

Hoses aren’t exactly lightweight, so think about getting a ceiling vent system. It’s almost as simple to install as a door ventilation system and is the finest solution for venting a portable air conditioner through a drop ceiling.


Some extra question you may have about portable air conditioner:

Do you have to empty the water from a portable air conditioner?

In most cases, your portable air conditioner will not need to be drained. Some portable air conditioners use a condensation exhaust system to expel the water vapor collected during the dehumidification/cooling process. When this situation occurs, you will need to drain the internal water tank.

Do any portable air conditioners don’t need a window?

There are no portable air conditioners without access to the outside of the building. Without the hose in the window or a hole in the wall, they would simply remove heat from the air on one side of the air conditioner and put it back in the room on the other side of the air conditioner.

What happens if you don’t vent the portable air conditioner?

If the AC unit is not vented outside or to another room, hot air will remain locked inside the space. The less humidity inside a room, the colder it feels. If you do not ventilate the portable AC unit, moisture will continue to accumulate and neutralize the cooling effect of the air conditioner.

Can I use portable air conditiner in windowless room?

Yes you can put a portable A/C unit in a windowless room, but unless the exhaust is ducted outside, it will not cool the room.
