How to Vent a Portable AC without a Window 2023

Portable air conditioning isn’t new, and there are plenty of gadgets and devices that fall under that broad category. When you are looking for something a little more powerful than a desktop unit, a portable air conditioner is an excellent choice.

These systems can cool any room in your home or business, although ventilation can be an issue that rules these cooling machines out for some. In this guide, we are going to show you how to vent a portable air conditioner without a window.

Portable Air Conditioners

A portable air conditioner is similar to a window air conditioning system in more ways than one. Both are self-contained systems that are built to cool a room. They are also cheaper whole house HVAC systems although a portable air conditioner is designed to sit inside of a room, not hang from a window. They also both require ventilation in order to work properly.

The big advantage with a portable air conditioner over a window AC unit is the fact you can use it in rooms with or without windows. It is also easier to move from room to room if you have a window and a vent kit. Depending on the layout of the room, there are a number of ways you can deal with the hot exhaust air released from your system.

Ways to Ventilate a Portable Air Conditioner

Ventilating a portable air conditioner comes down to placement. You generally don’t want to use an extension cord, and you need to keep the exhaust hose straight as well. While the machine itself can be attractive, the hoses aren’t. They can also be noisier than a window-based unit, so consider the distance to the venting location as well.

Venting through a door

Due to the way a portable air conditioner is designed, warm air has to go somewhere. Ideally, that will be outdoors, although that depends on where the unit is placed. If it’s in the living room in the middle of your home or a server room at the back of a building, door ventilation isn’t an option. If the system sits near an entrance or exit door, you could be in luck.

The easiest way to vent a portable air conditioner through a door is to use a sliding door. There are kits built specifically for sliding doors, which allows you to vent the exhaust outdoors. They are incredibly easy to use and will accommodate any machine as well.

Another alternative comes into play with pet owners. Do you have a small pet door located in your home which allows your furry friends to come and go as they please? While they won’t be thrilled with the situation, it can provide temporary ventilation when you need to run the system. Just make sure you can get a tight seal around the entrance for the exhaust hose.

Venting through the ceiling

Another option comes into play if you have drop ceilings in the room where the portable AC unit will be used. It’s not something you’ll find in too many modem residential homes, but common in older homes with high ceilings asking with offices and commercial property.

You can usually rig an exhaust vent to work with a drop ceiling tile in your home, but it may be far more trouble than it’s worth. Hoses aren’t exactly light, so consider a ceiling vent kit. It’s the best option for running a portable air conditioner vent through a drop ceiling, and almost as easy to install as a door ventilation system.

Venting through a Wall

When all else fails, and you need to send the exhaust from your portable AC unit outdoors, the last option is the most drastic. You can install a vent in the wall of your business or home, but it’s a permanent solution for a portable cooling system.

Before you start gathering tools or consider hiring a professional, take a minute and think about how often you will actually use the portable air conditioner. If you’re okay putting a relatively large hole in your wall, consider placement, and then pick up some tools or the telephone. Here’s a good idea of what to expect for a “simple” installation.

Cutting a hole for a vent is relatively simple on a residential home, although you still have to be wary of wiring, plumbing, and studs. While it may seem obvious, it’s a good idea to consider what’s outside of the wall as well; not just the inside.

Drywall and wood are easy to cut through, whereas brick or stone will be far more difficult. While this shows a dryer vent installation through brick, the same general process is used for venting a portable air conditioner through a wall.


A portable air conditioner is a perfect solution for millions of homeowners in need of efficient spot cooling, temporary or not. As you can see, if you don’t have a window, you don’t have to rule out these portable systems as there is more than one way to vent these machines. If you do have a window and feel a traditional system may be better suited to your needs, check out our list of the top window air conditioning systems.


Q: Can I vent a portable air conditioner through a dryer vent?

A: There are plenty of people that do it, but it’s not recommended by companies that make portable air conditioners, and we don’t recommend it either.

Q: If I vent a portable AC unit through a wall, how do I cover the hold in the winter or when my system is stored?

A: They sell caps that fit onto the end of vents for this purpsose. They can block both the inside and outside from the elements. Some kits may come with them; otherwise, you’ll need to check on sizes beforehand.

Q: Should I extend my vent hose if it’s a little short?

A: That will decrease the efficiency of your unit, and is typically not recommended.

Q: Can I use my attic to vent my portable air conditioning system?

A: This is another thing that some homeowners do, but something we do not recommend. There are too many variables that can lead to issues in your attic, and safer alternatives are usually available.

    To cool a room, all portable air conditioners must be properly installed and blow out hot air as it cools. This warm air is usually expelled outside with the included window kit, but traditional windows are not always available.

    Why ventilate a portable air conditioner?

    Mobile air conditioners cool your room by removing hot air from the room. If warm air is not vented outside, it will stay in your room, negating the cold air that enters your space.

    How to install a portable air conditioner with a window kit

    Most portable air conditioners, compared to cassette air conditioners, are easy to install and ventilate with a window kit provided by the manufacturer. In just a few steps, you will be on your way to a more comfortable interior space.

    Standard window kit includes a window bracket, one or two vent hoses and vent hose adapters. Follow these steps to quickly set up your portable air conditioner:

    1. When venting the portable air conditioner, connect all hose connectors/adapters and insert the hose(s).
    2. Extend the adjustable window kit to the length of your window. If necessary, trim the window bracket to fit snugly against the window. Your specific model may come with screws to hold the window kit in place. Then close the window to secure the kit in place.
    3. Then connect the ventilation hose to the window kit. If your model is properly installed and ventilated, you can start cooling immediately. Just plug it in and program your settings.

    Sliding Window and Sliding Door Ventilation

    Standard window brackets are designed for horizontal installation at the bottom of windows, but can also be installed vertically to fit sliding windows and sliding doors. Some window bracket modifications may be required to install air conditioners on sliding windows.

    For sliding windows, make sure the bracket is long enough to fit the opening. Blocks with double window brackets usually work well for sliding windows. The double bracket includes a standard window bracket and an optional filler bracket. After installing the bracket, if there is still a hole in it, you can fill it with insulation.

    With sliding window air conditioners, the window brackets will not be long enough to fill the vertical opening, so you will need to fill the extra space with some other material.

    Casement windows

    Since casement and pivot windows open like doors, standard window sets are not suitable. Many buyers who have hinged windows simply cover the entire window opening with plexiglass and cut out a hole for the exhaust hose.

    Wall ventilation

    Some people prefer to vent hot air through a vent in the wall, directly outside or into another area such as a garage or storage room. You can use a jigsaw to cut a hole to the desired size in the wall, but make sure there is no wiring or plumbing where you want to cut the hole. The edges of the hole can be sealed with silicone sealant.

    Our works | Alkon-Klimat

    The company “Alkon-Klimat” has been performing installation and maintenance of air conditioners, as well as heating and ventilation equipment for more than fifteen years. During this time, a large number of various works at the facilities have been completed.

    We invite you to familiarize yourself with some of our works. Here you can see examples of installations of household split systems, mobile air conditioners, ventilation systems for household and other purposes.

    Inverter split-systems Mitsubishi Electric in a cottage – suburb of Ufa

    Split-systems Mitsubishi Electric have gained their authority by introducing the most modern technologies, high quality components and the highest level of consumer characteristics. As for inverter split systems, they occupy a leading position in terms of efficiency and low noise level.

    The customer expressed a desire to install premium class split systems, and we offered Mitsubishi Electric inverter air conditioners.

    The first stage – laying of interblock routes.

    The second stage – installation of blocks and commissioning. All split systems with inverter.

    In the living room – a powerful and efficient split system, designed for 50 square meters.

    In the bedroom – a silent inverter split system with additional air purification.

    Successfully placed blocks do not spoil the design.

    On the attic floor we install a column inverter system with a service area of ​​up to 100 square meters.

    Ventilation of the utility block at the Alekseevsky state farm

    During the construction of a new greenhouse complex at the Alekseevsky state farm, the installation of supply and exhaust ventilation of the utility block was required. Our company acted as a subcontractor for these works.

    Supply and exhaust ventilation is based on NED equipment.

    Mobile air conditioner in a bank branch (when split systems are not allowed)

    In buildings of historical and architectural value, restrictions apply to the installation of equipment on the facade. But how to ensure the cooling of the room, if the installation of split systems with their outdoor units is not allowed?

    At one of the sites of our regular customer, we faced such a problem. To solve it, mobile air conditioners were used. Emission of heated air outside the premises was carried out by means of plastic air ducts.

    Picked up a reliable and efficient mobile air conditioner

    Extraction of warm air from a mobile air conditioner outside the premises

    Ventilation in a private pool – a suburb of Ufa

    “Alcon-Climat” often performs tasks to ensure the microclimate in the premises of private pools. As a rule, for this we install supply and exhaust ventilation. Such work is carried out in close contact with the contractor for the construction of the pool. This is necessary so that we can make accurate calculations for air exchange and the correct location of air ducts and ventilation equipment in the premises.

    In one of these pools, located in the suburbs of Ufa, we installed such a ventilation system from Shuft.

    At the stage of finishing, we mount air ducts

    Air ducts are located around the perimeter

    Mounting ventilation equipment and tying heaters

    Lattices organically fit into the design. It turned out beautifully

    Wall mounted dehumidifier installed. For reliability

    Management is extremely simple. Automation will do everything by itself. These works are carried out in several stages as construction and finishing works are completed. At the first stage, interblock routes for split systems are mounted and the air duct is installed. At the stage of completion of finishing works, installation of split-system units and ventilation equipment is carried out.

    Shuft and Ballu fans, as well as an Intekh air handling unit, were used to ventilate this facility. For air conditioning – wall-mounted and cassette split systems Tosot.

    Installation of interblock routes at the stage of finishing

    After the wall is insulated, we mount the outdoor units of inverter split systems Tosot

    Inline fans in sound-insulated housing

    Indoor units of split systems are located in less visible places

    Fresh air is supplied to the house by a smart supply unit of the Intech brand with an EC motor

    Installation of the Ballu wall split system on the finished route – Ufa

    If you do not want the communications from the air conditioner to be visible, then lay the route between the blocks split systems are best done at the stage of finishing work. When the finishing is completed, the indoor and outdoor units are installed.

    Below are photos of installation of Ballu wall split systems. As you can see, all communications are hidden in the wall and everything looks neat.

    Routes laid in advance

    All communications are hidden in the wall, nothing extra sticks out

    Installation of a split system with a route through the loggia – Ufa

    If the repair of the room has already been done, then we perform surface mounting. The route is laid in a plastic cable channel.

    Here is an installation example of a Ballu inverter air conditioner with a surface mount track. By the way, this Ballu model shows not only the indoor temperature, but also the outdoor temperature, as well as the performance level of the inverter.

    Repair already done, so we are doing surface mounting

    We lay the route through the loggia in the cable channel

    Ventilation of a small pool with a compact unit Lessar – Ufimsky district

    Another swimming pool in a private house. Here, its area is not large, so the Lessar compact air handling unit with a heat exchanger and built-in automation is very suitable. In winter, the heat exchanger saves more than half of the energy, using the heat of the exhaust air to heat the supply air.

    The designer skillfully concealed all the elements of the ventilation system, while the ventilation perfectly fulfills its purpose, creating a comfortable environment.

    Installation of flow and exhaust air ducts

    We mount the Lessar compact air handling unit with a plate heat exchanger

    Connection of air ducts and heat carrier to the ventilation unit Lessar

    The pool has an interesting design, but the ventilation grilles do not spoil it at all

    Supply dry air is directed to the glazing area to prevent moisture condensation on the glass

    Despite the high ceiling and large volume, the ventilation unit provides a very comfortable microclimate in the room. To do this, Lessar modular chillers are installed on the upper level, and the cooled coolant from the chillers is distributed by floor. Fan coil units are installed inside the apartments, which cool the air.

    Our company “Alkon-Klimat” has carried out piping and installation of wall-mounted fan coil units in many apartments of the “Idel Tower”.
