Air conditioners significantly improve living conditions both in the city and beyond: it is they who turn the stuffy “boxes” into cool, comfortable dwellings on hot summer days, and in the winter heat the air in the rooms to a comfortable temperature.
Mobile climate technology is a separate category. Unlike systems with wall and remote units, it is not tied to a specific place, but simply installed on the floor in a convenient area for a while.
In this article, we will analyze in detail how to install a floor air conditioner so that it works properly and 100% copes with the tasks. And if you want to independently connect a mobile unit, then we will show you how best to remove the duct outside the room.
What is the advantage of mobile technology?
The question immediately arises: is this bulky floor equipment really necessary when it is possible to buy a traditional, more familiar split-system in use?
Floor-mounted monoblocks are classified as mobile equipment, that is, equipment that can be moved from place to place at will - moved from the living room to the bedroom, and, if necessary, taken to the cottage.
Monoblock air conditioning has gained popularity due to its simple connection. Its design is characterized in that both the condenser and the evaporator are placed inside one enclosure installed indoors
Units are attractive for those who like to change the situation, but live at the same time in the most comfortable conditions. Here are 4 main qualities that regular users have positively rated in floor models:

Mobile technology is good because it is not fixed in one place. Not only that - the case is equipped with wheels for convenient movement of the unit from one room to another. Bulky, but lifting air conditioning can be used as a temporary, seasonal summer cottage option with easy installation
The design of the air conditioner consists of only one unit, which is located inside the living room. Outside, unlike a split system, nothing needs to be fixed. Accordingly, there is no need to worry about how the facade of the building will look - especially of historical value
There are also solid pluses: if the installation of the split system is better to entrust to professionals who will connect the two blocks through the wall, then the floor unit should simply be placed on the floor near the window or door to the balcony, while the walls do not have to be drilled
If you select a device recommended for power and performance for a particular room, it will work no less efficiently than an expensive split system. And in terms of safety, the plastic block is comparable to a refrigerator - it’s kind of volatile, but absolutely harmless
The installation location can always be changed
No special installation permission required
Simple installation and connection
Efficiency and safety
As you can see, floor-mounted monoblocks are in some ways better than split systems, and to install a home mobile air conditioner you do not need to hollow walls and install brackets from the outside. Maintenance of the unit also takes a little time, and at a cost it is no more expensive than alternative models.
There are mobile air conditioners without ducts. But they have many disadvantages: loud noise, low efficiency, the need for regular maintenance.And the most unpleasant thing is the high humidity in the room
If you opt for outdoor equipment, carefully read the next section to better familiarize yourself with the mounting nuances. Knowing how to install a mobile air conditioner correctly, you can provide a comfortable indoor microclimate without the help of specialists.
Floor air conditioner installation instructions
The main difficulty in the installation is the withdrawal of the duct outside the room. If you want to quickly put the air conditioner into operation, then you need to take care of installing a sufficiently large corrugated pipe in advance.
We will provide options for arranging a hole in a wall or window below, and your task is to choose the least costly and most convenient solution.
Stage # 1 - choosing the installation site
But first you need to choose the most suitable place for installation. Two important points to consider here:
- The air outlet hose is limited in length, so the unit must be placed as close as possible to the outlet - that is, to the window, balcony, etc.
- The power cord also usually has a standard length of 1.8 meters, so a power outlet should be nearby.
Anywhere - in a free corner, in the center of the room - you won’t be able to put a candy bar. The fact is that it is impossible to extend the power cord or duct both according to safety requirements and technical standards.
If you manage to somehow increase the length of the corrugated duct, then you will encounter another problem - a decrease in performance. And useless equipment in the house is not needed.
According to the installation requirements, the distance from the monoblock to the nearest walls or partitions should be at least 30-50 cm, otherwise there may be problems in operation and maintenance
Another important point is an even and solid foundation. In old houses there is a sloping floor, it will have to be leveled. To do this, it is not necessary to sort the boards or make cement pouring; you can put gypsum boards or thick plywood on top of the existing flooring.
Stage # 2 - conclusion of the duct to the street
One of the drawbacks of floor air conditioners with an air duct is this very air duct - a thick corrugated pipe, one end of which is integrated into the unit body, and the other must be brought out onto the street.
Through the duct, warm air is discharged outside the living room. The task is to place the duct so that the heated medium does not return back to the house
We offer the most successful, in our opinion, option, thanks to which two main goals can be achieved:
- ensure the output of heated air to the outside;
- keep attractive window design.
As a result of the work done, you can open the window sash for the duration of the air conditioner and connect the air duct to the frame with plexiglass inserted according to the mosquito net principle. Plexiglass transmits light well and has the strength necessary for strong fixation of the pipe.
A diffuser inserted into plexiglass and acting as a fastener will look good both from the room and from the street
All work can be done independently. If you don’t find a tool, you can buy it, ask your friends, or rent it.
You will need:

A large piece of white or transparent plexiglass
Standard frame with mosquito net
Supply and exhaust diffuser with grille
Plexiglass Tools
The elements for fixing the air duct - a strap, a diffuser or an adapter - must be made of more flexible and lightweight plastic, metal fittings are not suitable.
Also required:
- building tape;
- long metal ruler;
- pencil or marker;
- construction knife;
- sealant;
- a cleaner;
- sandpaper.
Prepare sponges, rags, containers with water - all that is necessary for cleaning and degreasing materials.
Sequencing:
Step # 1 - cut a piece of plexiglass to fit the frame.
First, measure the length and width of the frame with a mosquito net, then transfer the dimensions to plexiglass and cut a piece.
The corners will be fixed on the edges of the frame in order to fix it on the window, so the glass should be slightly smaller than the frame. To find out how much, we apply corners to the edges of the frame and make the same indentation on the glass.
To cut a piece of plexiglass, you can use an aluminum profile: apply it to the drawn line and draw it several times with a construction knife. Then just bend along the cut line.
If there is an electric angle grinder at hand, you can also use it - just gently slide the disc along the drawn lines
The uneven or fused edges of the finished rectangle need to be chipped with a knife or sanded with a fine “skin”.
Step # 2 - cut a round hole under the duct.
We determine the place where the hole will be located - this is the lower part of the frame, that is, about 15 cm from the bottom edge of the Plexiglas sheet. We apply the narrow part of the diffuser, circle it with a marker or a knife. For cutting we use a jigsaw or a homemade soldering iron.
To make a knife for melting and processing plexiglass, you need to insert a blade from a regular knife into the working tube of a 60 W soldering iron. With this tool you can cut any plastic parts
Having cut the circle to the end, squeeze out a circle and get a hole of the desired diameter. We clean the edges with a knife or sandpaper.
Step # 3 - we fix plexiglass on the frame from the mosquito net.
It is important to maintain consistency here: first fix the glass, and then remove the mesh and the fixing rubber cord, otherwise the frame will lose stability or just fall apart into separate elements.
For gluing, it is best to use a sealant, but first you need to degrease the frame.
Isopropyl alcohol, which forms the basis of all household and building cleaners, is ideal for degreasing. It can be bought at the construction market
Put alcohol on a cloth and wipe the frame around the perimeter. Glass at the edges can be treated with sandpaper to increase adhesion.
Then we squeeze out a transparent universal sealant using a construction “gun” and apply plexiglass. First remove the protective film from the glass - until this point it is better not to touch it.
To ensure that the glass adheres well and adheres to the frame, additional weight is required. You can use books, a heavy tool or containers of water - cans or buckets
After the sealant has dried, the mosquito net can be removed. First, gently pull out the rubber cord, then pull the net, and insert the cord back. This is necessary to fix the plastic holders, “ears”, located at the edges of the frame.
If you think that the cord is not needed, remove it with the net, and glue the “ears” on the sealant.
Step # 4 - insert the diffuser into the hole and fix it.
We first disassemble the diffuser into several parts, we obtain a pipe segment, a grill, a grid and a locking element in the form of a circle with “reeds”. First we insert a plastic tube, then we attach a small mosquito net to the wider end, twist the grate, and on the other hand we put in a lock circle.
A sealant or screws will not be required to fix the diffuser on the glass - the kit contains a round polymer element that tightly "sits" on the pipe and holds it
Everything, the frame with the designed hole for attaching the duct is ready. It remains to open the sash and insert it into the window to check operation. If you coped with the conclusion of the corrugation of a mobile air conditioner, consider that the installation was a success.
Stage # 3 - Power Connection
A power outlet is required for the air conditioner to work. The main thing is not to overload the wiring, if it is not provided for the installation of powerful equipment.Manufacturers do not insist on providing grounding or installing a separate machine, but the presence of RCDs is usually specified in the instructions.
Experts recommend installing a chipovaya socket with an integrated RCD. It is weaker than the electromechanical analogue, but can withstand up to 4 kW - for an air conditioner, no more than 2.5-3 kW
The socket must be near the unit, and therefore, from the window. Using extension cords, filters, or other similar electrical equipment is not recommended.
General requirements for electrical installation:
- Use only certified equipment and wires.
- Do not use the air conditioner if the power cable is broken.
- Disconnect the unit from the power supply before any repair or maintenance work.
- Do not allow water to enter the chassis, such as raindrops from a window.
Some air conditioners heat up when operating at full power, so make sure that children and animals do not come up with the devices turned on. In any emergency situations - smoke from the unit, burning odor, leakage - immediately unplug it.
Stage # 4 - testing and operating rules
The first start-up should only be carried out after the duct has been brought out. You also need to make sure that the power supply is working.
Procedure:
- We check the tightness of the corrugated pipe connection.
- Insert the plug into the outlet.
- Press the key or the "On" button.
- We select the operating mode, temperature, fan speed.
- Click the "Start" button.
Make sure doors and windows are closed. After some time, you should feel the change in air temperature in the room. If this does not happen, check if you have chosen the correct operating mode. In case of difficulty, call the service center.
If vibration or loud noise appears, check if the air conditioner is installed correctly. Under the monoblock there should be a flat surface, without debris, dents or bulges
To clean the case, use soft rags and sponges, only neutral detergents that cannot scratch the plastic or wipe off the gloss. Clean the grate with a soft brush.
Remove and rinse the filter from time to time. The recommended interval is after 3 months. Use only clean water and mild detergents free of alcohol and acids.
As the sump is filled, drain the condensate. To do this, remove the plug from the hose and lower its end into the container. Typically, a little condensate builds up, as for the most part it evaporates naturally.
Other options for connecting corrugations
We examined in detail the best option for the outlet of the duct - into the hole in the window.
But there are other solutions. All of them are less successful, and now we will explain why:
- The output of the corrugation into the window, transom or ajar window. This is often done by everyone who does not get their hands on equipping a more acceptable unit. Cons - heated air immediately returns to the room, the efficiency of the unit decreases.
- Air outlet through the balcony door. A bad option if the balcony is glazed, if not - the minuses are the same as in the solution with a window leaf.
- Connect the pipe to the hole knocked out in the wall. An acceptable option, if you provide maximum thermal insulation.
The latter solution is suitable if you use a mobile air conditioner constantly.
For drilling walls made of concrete or foam blocks, a perforator with a long crown and a vacuum cleaner are used to remove debris. In order to stabilize and fix the crown during operation, a plywood stencil frame is fixed on the wall
When the air conditioner is turned off, the hole is closed. You can use the “plug” from the insulation, or you can put a replacement - the ventilation valve.
In private homes, there are sometimes windows with lifting or sliding sashes. They are convenient for the outlet of the duct - the sash is pushed back, and a plastic or plexiglass panel is inserted in its place.
In the plastic panel, as described in our manual, a hole is cut out, then an adapter or diffuser is inserted into it, and already in it is a duct pipe
Any option is suitable if the heated air remains on the street and does not return to the room through open windows or doors.
