How to install an air conditioner in a plastic window: technology secrets and installation guide

3 Dismantling of the old structure

Experts recommend carrying out this procedure immediately before installation. Usually, old windows are thrown away, so the frame can be removed with fasteners, sawn in several places. With the help of a crowbar and a nail puller, parts of the block are hooked and pulled out. Under the box is a thermal insulator and seal, which should be removed. A perforator with a special nozzle with a spatula removes the plaster from the slopes.

Next, the window sill is hooked and dismantled. Under it and the opening, the cement substrate is removed using a perforator. The ends are cleaned of dirt and dust. Adjacent surfaces are treated with a primer. If the slopes are made of wood, a waterproofing layer is laid around the perimeter to protect the mounting foam from moisture penetration from the wooden structure.

Construction debris, the remains of the window block are collected in bags and taken out to the places intended for this.

Does it make sense to install a plastic window yourself?

To begin with, let's try to deal with the question, does it even make sense to install PVC windows with your own hands? Contrary to popular belief, installing windows is not that difficult. For its implementation, you do not need to stock up on professional equipment and gain special experience for a long time. The installation procedure itself consists of two stages:

• dismantling of the old structure;
• installation of a new plastic window.

Usually, dismantling takes from 0.5 to 1.5 hours. Direct installation of the window (we take an average window measuring 2x2 m) will take another couple of hours. It turns out that to replace one window, it will take a maximum of three and a half hours.Therefore, for Saturday-Sunday, you can freely change at least 2 windows without resorting to the help of specialists. Considering that installers charge $40-60 for each window installation, we get quite good savings. Some companies set the cost of installation as a percentage of the cost of windows. For different specialists, this amount varies and is about 10-40% of the price that is proposed to be paid for windows. Also, specialized companies, when ordering windows from them, can deliver a new design to your home and dismantle it free of charge.

Trusting the installation of windows to specialists, you can demand the following guarantees:

1. when buying windows from a third-party company, installers provide a guarantee only for installation seams and their filling, the correct geometry of individual elements and the functionality of the window structure for 1 year after the work has been completed. Since self-assembly practically deprives you of the warranty for window structures, you need to be more careful in choosing products. It is better to prefer windows made at the factory, in compliance with all technical requirements and conditions. Handicraft products are a “pig in a poke”, the quality and functionality of which can bring an unpleasant surprise. In this regard, to purchase window structures, it is advisable to contact directly a manufacturing company that has been operating on the market for a long time and has good reviews from numerous customers. By the way, if you order windows in winter or spring (i.e. out of season), you can get a significant discount;
2. when purchasing windows from a company that carries out installation work, the customer receives a guarantee for fittings - from one to 5 years (the more expensive the windows, the longer the warranty period, as a rule);
3. if the windows are installed with your own hands, then the guarantee for fittings must be requested at the place of purchase of the structures. You will have to take full responsibility for the quality of the seams.

Installation of pvc windows with your own hands should be done if available:

• a couple of free days (as an option - days off);
• diligence and desire to learn something new;
• desire to save.

If all of the above is present, then the recommendations outlined in this article will allow you to successfully replace the windows in the house, making it no worse than a professional installation team. Actually, a whole team is not required to install the window; two people will be enough, one of whom will perform the installation, and the other will hold the structure and supply the necessary tools. Despite the apparent complexity, self-installation of PVC windows is a rather simple process, which is a combination of several simple operations performed in a given sequence. Before proceeding with the installation, you need to order a window, and for this you need to correctly perform preliminary measurements. So…

How to install correctly: choosing an installation method

There are two different methods: with and without unpacking (disassembling) the window. When unpacking, holes are drilled through the frame, through which an anchor is driven into the wall. This method is more difficult, but the mount is more reliable.

This is an anchor bolt. They are placed three pieces on each side.

When installed without unpacking, metal plates are attached to the frame from the outside, and then they are attached to the walls.This, of course, is faster, but the fastening is very unreliable: with significant wind loads, the frame will warp or it will sag.

This is the fastener most often used by installers. As in my opinion, look unconvincing

If you really don’t want to disassemble the window, you can also mount it on a plate, but use not narrow and thin ones, but thick and wide ones, which are still often used when installing the truss system.

In principle, small windows mounted on mounting plates, provided there are no significant wind loads, can stand normally. If you live in a region with strong winds, and they blow mainly through your windows, if the apartment is located in a high-rise building on a high floor, in these cases installation with unpacking is necessary.

Watch an emotional and intelligible video below, which explains why it is better to use an anchor.

Floor and ceiling models

These include floor-to-ceiling air conditioners, the installation of which differs only in that they can be located on the wall near the floor or under the ceiling. Otherwise, they are not much different from other split systems in terms of their performance.

The main technical differences from other models of household air conditioners are as follows.

1. Versatility - location in any place convenient for users. From the type of location, the optimal direction of the air flow of the cooled air is selected.
2. Small dimensions, therefore, can be installed in any, even the smallest in size rooms. Their indoor units are much smaller than those of split systems, in addition, they are thinner, but longer than other models of wall-mounted air conditioners.
3. Quite high performance - they are in no way inferior to wall-mounted models, and the efficiency of the heat exchanger and fan is identical to more expensive samples of split systems.
4. The main tasks assigned to these systems are cooling and heating of air depending on the season. In addition, they perform a rough cleaning of the air mass from impurities and its ionization.
5. The level of sound impact on others is very small, the most powerful models of floor and ceiling products have no more than 34 dB, and a quiet atmosphere in any library is 40 dB.

Winter setting

In the autumn period of the year, it is recommended to switch the window system to winter mode. This will prevent heat leakage from the home and the appearance of drafts.

Sometimes before winter, windows can not be adjusted. This usually depends on the condition of the sealing gum. If it is new and in good condition, then the windows can be left in the "summer" mode and not worry that it will be cold in winter. But if the gum has already worn out, lost its elasticity, then you should think about reconfiguring the window.

Winter window adjustment

In general, the first three years of operation, the windows serve flawlessly even in summer mode. Then the natural wear of the elements is noted, and adjustment is no longer enough. The degree of window pressing every year will have to be done higher and higher. But it’s not worth it to “tighten all the bolts” right away, so as not to deform the seals ahead of time.

The first three years of operation, the windows serve flawlessly

Determining which mode the windows are currently in is easy. It is necessary to inspect the sashes and assess the degree of their pressing to the frames.To do this, you can take a piece of paper and insert it between the frame and the window, and then close the window. If, after it has been closed, the sheet falls out or is easily pulled out, then the window is in summer mode and needs to be adjusted. If the sheet sits tightly or breaks when you try to pull it out, then the window is in the “winter” mode and does not need to be adjusted.

Do-it-yourself adjustment of winter-summer plastic windows

You can also see how the eccentric is oriented. There is a special mark on it, which will show how the window is configured. If the trunnion is turned with the icon towards the street, then the window is in the "summer" mode, if it is oriented towards the apartment, then the window is in the "winter" mode. If the trunnion is oval, then you need to look at how it is located: if it is vertical, then the window pressure is weak, if it is horizontal, then the pressure is stronger and this is the winter mode.

Location selection

The presence of two or more blocks of climatic equipment provides for the choice of a place for each of them. Before starting installation work, accompanying documentation will be required.

Do I need a permit to install an air conditioner?

Structurally, the air conditioner is a system with an indoor and outdoor unit, which is mounted on the facade.

Multi-storey building, on the basis of art. 246 of the Civil Code is common property with the right to dispose of all owners. Installation of equipment without approval is a violation:

• the device makes noise, buzzes, disturbing the peace of neighbors;
• condensate can damage the facade of the building or get onto the balcony from below;
• the overall block blocks the view or view and windows;
• there are risks of cracking walls, short circuit wiring and fire.

Based on paragraph 1 of Art.25 LCD installation of a split system is considered as a reconstruction or re-equipment of the premises. Clause 3.5.8 of Decree No. 170 informs about the prevention of installing an air conditioner without permission from the management company and neighbors. Consent or refusal can be obtained only after a meeting of the tenants of the house.

Important! Residents of private homes can start installation immediately after purchasing the device. Permission is required if:

Permission is required if:

• installation work is carried out on the front of the high-rise building;
• the user lives in a house of value in terms of history and culture;
• split system is located above the footpaths;
• there are no special fences on the window opening where the unit is located.

Important! The management company does not have the right to rent air conditioners. Art. 330 of the Criminal Code considers such actions as arbitrariness

Dismantling of devices is carried out only by court order.

Choosing a place for the indoor unit

Installation of the internal module of the air conditioner is carried out by hand so that cold air flows do not cause discomfort. It is allowed to be placed above the head of the sofa, on the side and behind the workplace. Building codes define the order of location of the indoor unit:

• from the structure to the ceiling - at least 15 cm;
• from the module to the right or left wall - at least 30 cm;
• from the block to the floor - 280 cm, but for apartments on the first floor, the outdoor unit is mounted at the same level or lower than the indoor one;
• from an obstacle to the movement of air flows - not less than 150 cm;

Advice! In a room with a sofa and TV, it is better to place the air conditioner above the sofa.

Where to locate the outdoor unit?

The outdoor module is located near the window opening or on an open loggia. If the balcony is glazed, the block is placed on a fence with good bearing capacity or on the facade. Residents of floors 1-2 need to determine a place for the outdoor module as far as possible from passers-by. On the 3rd or more floors, it is allowed to place the device under a window or on the side.

In a private house, the outdoor unit is placed on a wall with a high bearing capacity. On ventilated facades, a special fastening is organized or the block is placed on the plinth.

Determining the distance between blocks

The maximum length of the inter-module route is 6 m, if it is exceeded, additional freon injection will be required. If the outdoor and indoor module are placed at a distance of 1 m, the route should not exceed 5 m. The surplus of the system is formed into a ring and placed behind the block.

Interesting to know! Manufacturers specify different maximum distance between blocks. For Daikin equipment, it is 1.5-2.5 m, for Panasonic - 3 m.

Refueling window air conditioners

Before you refuel the unit, you need to understand if it needs refueling? In most cases, window devices do not need regular refueling due to the design features. Here, all connections are soldered, which reduces the risk of freon leakage.

It is unlikely that it will be possible to refuel the device on your own - for this, contact a specialized company. The craftsmen will find the place of the leak, solder it, after filling the copper tube with freon.

Window air conditioners are considered durable appliances. They are easily installed in the frame of a plastic or wooden window, are easy to operate and do not require refueling. Such units will become an effective assistant in the fight against heat in the summer.

Tips for installing an air conditioner.

People, trying to save money, install the air conditioner themselves. Such an installation is a rather risky undertaking, since all warranty obligations for the repair and replacement of equipment are removed from the manufacturer. Self-assembly and installation does not require special knowledge and special equipment. To install the air conditioner, it is enough to have tools such as a hammer, drill, hacksaw, as well as installation instructions and an assistant.

When choosing an air conditioner in a store, you can make a mistake with the dimensions, it may turn out to be wider and you will need to increase the window opening. Therefore, you need to know exactly the size of your window where the air conditioner will be installed.

It must be remembered that the indicated instructions for installing the air conditioner yourself can be used if you have wooden window frames. And if plastic windows are installed, you need to invite a specialist who will install an air conditioner for you.

The sequence of necessary actions:

• studying the documentation;
• determine the future location of the indoor and outdoor units;
• we make our way through the outer wall at the place where the connecting route is laid;
• we install a drainage system;
• we are laying a power line;
• we measure and assemble the pipeline for freon;
• we fix both blocks;
• connect them with a route;
• we start the system.

In no case do not wall up the air conditioner with concrete in the wall, as it needs natural cooling over the entire area. When installing a window in the opening, it is necessary to make a frame from a metal profile. The thickness of the metal profile is determined based on the dimensions of the apparatus and its weight. For some types of air conditioners, a metal profile is already included in the kit.

After that, it is necessary to measure the dimensions of the device and its frame. The installation location of the device should be increased by approximately 10 - 15 mm. We carefully install the air conditioner in the opening, and fill the remaining free space with mounting foam. The device is installed with an inclination so that the rear part protruding to the street is inclined so that the condensate that accumulates during operation is outside the ventilated room.

For the normal operation of the air conditioner, it is necessary to carry out additional wiring and a separate automatic package on the switchboard.

There are times when installing an air conditioner, the inner section of the window opening needs to be cleaned in full. After installing the air conditioner, glaze the free space above the equipment using glazing beads. This method is good because it saves time when dismantling the air conditioner, you just need to remove the glass and put the one that was originally installed.

Installation in a plastic window

Installing a window air conditioner in a plastic window is a laborious process associated with the design of the opening. It is best to mount the block inside a pre-prepared opening, which is made even before the window is installed. If there is no such opening, installing a window air conditioner in a plastic window is done as follows:

• the reliability of the window opening is checked, if necessary, strengthened;
• the chosen place should be such that after placing the air conditioner, there are as few gaps as possible;
• the double-glazed window is carefully removed from the window using the necessary tool (glazing beads are first dismantled, starting with the longest one);
• insert the jumper at the required height;
• fix the mounting kit at the required distance;
• close the remaining gaps tightly with plastic, or install the purchased plastic opening for window blocks;
• install a monoblock body inside the frame;
• insert the inner part into the case, install the front panel in place;
• cut carefully the double-glazed window along the length, side metal frames inside the chambers;
• insert the frames at the bottom at the place of the cut, treat the remaining gaps with sealant (it is necessary to ensure that dust does not get inside the chambers, if necessary, clean it before installing the metal frames;
• install a double-glazed window in the sash;
• cut long glazing beads to length, install in place;
• connect the device to the mains;
• to test operating modes.

The installation of a window air conditioner in a plastic window must be done very carefully, in compliance with the accuracy of the execution of technical points for cutting a double-glazed window.

PSUL is a necessary component for installation in accordance with GOST

It's time to tell you more about her. This is polyurethane foam impregnated with a special composition with an adhesive layer. The product is called PSUL, which stands for vapor-permeable self-expanding sealing tape. The use of this material does not require any special skills or abilities. It is simply glued to the window frame before it is installed in the wall opening. Then its independent expansion occurs, and it touches the wall with its second edge. That's it, the outer contour of the mounting seam is closed.

A separate issue is the lower part of the outer seam - the one that is under the outer drain on the street.Since the drain delays ultraviolet radiation, it is easier and cheaper to use not PSUL, but a vapor-permeable waterproofing tape based on a diffusion membrane. The principle of its operation is the same as that of PSUL - ventilation of the insulation and cut-off of direct moisture (it can get from the upper parts of the window, or from under the drain). The application also does not cause much trouble. True, this tape, unlike PSUL, contains not one, but two adhesive layers. One of them is intended for fastening to the wall, and the second - as a rule, to the stand profile.

Self troubleshooting

If your air conditioner suddenly stops cooling the air in the room entrusted to it, you can independently determine the cause of the problem:

• Does not work. The reason may be a power failure. It happens due to a damaged plug or cord, a blown fuse, or a power outage.
• Weak cooling. The airflow is obstructed by a dirty filter, an obstruction, or a nearby heat generating device.
• Heats up badly. The outdoor heat exchanger is icy, preventing air circulation.

A normally operating window air conditioner will make a barely audible click when the thermostat starts and stops, and after the compressor is turned off, the fan will still work for a short period of time.

Features of mounting the device

Knowing how to install a window air conditioner isn't enough to keep your system running efficiently at all times, there are many things you need to pay special attention to.Of course, such a device in the form of a monoblock system is much easier to install a more complex split system, since there is no need to run a route between the blocks for refrigerant and drainage, but it also has its own features.

• Experts recommend installing a separate outlet with a separate machine, even for devices that have very little power.
• When choosing a model, be sure to consider the width parameters. It must be less than the width of your window.
• There must be enough free space around the device. so that it can work properly.
• Unlike the outer edge, which is below the inner side, the left and right sides of the appliance are installed evenly. otherwise, the condensate that accumulates during operation will unevenly drain from the sump.

The main stages of preparation in a private house

Preparation can be done in 2 ways:

• with the help of supporting reinforcement;
• by integral fastening.

Actions:

1. Remove the old double-glazed window together with the glazing beads. Number them so that they are installed in the same order during installation, to prevent gaps from appearing.
2. Tilt the frame slightly towards you, remove the glass.
3. Remove the plugs from the canopies, unscrew the bolts.
4. Turn the handle to the ventilation mode, slightly open. Remove the transom so that special jumpers for separating the sashes do not fly off the frame.
5. Mark points for anchors, 2 on the bottom and on top of the glass package, 3 on each side. Drill holes.

If the walls are made of cellular concrete ((in a panel house), i.e.

fragile, it is important to make fasteners from anchor hangers. Fix to the wall with hardened screws

If the old elements (for example, metal) cannot be removed in any way, then you can cut them.Next, clean the work area from dust.

Dismantling works

Dismantling works

When the new window is delivered, dismantling work should begin. Removal of the old window should be carried out in dry and calm weather. If it becomes necessary to replace the frame in the winter season, then the installation of the plastic frame should be done only using frost-resistant mounting foam.

When removing an old window, a large amount of dust is generated, so it is recommended to cover all the furniture in the room with plastic wrap. The dismantling of the old window is carried out in the following sequence:

• Frame freed from glass
• Plaster is removed from slopes
• The window sill is being dismantled

In order to significantly speed up the process of removing the old frame, you can use a hand saw for wood. To perform dismantling, it is usually enough to cut the middle and lower parts of the frame.

Time and nuances of using polyurethane foam

The main characteristic feature of the installation of window structures is the use of mounting foam during work, which ensures high reliability of fixing the frame with the opening. After completion of its polymerization process a layer is formed, which not only additionally fixes, but also acts as an insulating material.

In order to avoid the loss of positive technical indicators of the mounting foam in the future, it also needs to be properly processed.To protect it from the negative effects of not only the outside environment, but also adverse effects inside the building, it is required to glue insulating strips. From the street, they should have a waterproofing effect, and indoors, a vapor barrier effect.

At what time of the year the owner chooses to install a plastic window. Often, experts advise to install in the winter, because it is at this time that all the shortcomings quickly appear. When choosing a mounting foam, it is imperative to take into account at what temperature value the best solidification of the composition occurs. It is recommended to give preference to professional mixtures.

If the work is carried out at sub-zero temperatures, then you should additionally also purchase a special nozzle, through which the mounting foam will be sprayed. How this process is required is described in detail by the manufacturer on the containers themselves.

Basically, the spraying of the mixture starts from the bottom, moving upwards in a rotary-circular motion. In order to avoid excessive consumption of expensive material, it is optimal to spray mounting foam in several approaches, filling it with a space of 25-30 cm in length.

Important! To shift the dew point, it is recommended to foam with different thicknesses of the applied layer. From the side of the street, it is desirable to make it thinner than from the room

Along the perimeter, the mounting foam must be sprayed evenly, avoiding voids and missed areas.

Wooden window installation

The least expensive and simple to install the block in a wooden window. Installing a window air conditioner in a wooden window hole, the sequence of actions:

• prepare a place for placement in advance before installation. Take the external dimensions of the device, make the necessary marks on the window frame;
• carefully remove the glass from the sash;
• mount a wooden jumper at the marked level so that the outer case of the monoblock is placed inside the resulting opening without excessively wide gaps;
• the remaining space on the sides of the air conditioner housing must be covered with a suitable material (plastic, wood, etc.), or a special insert for window blocks must be purchased and installed inside the opening;
• the frame from the mounting kit is securely fixed at a predetermined distance, taking into account the downward slope of the outer part;
• mount the block body inside the opening;
• insert the air conditioner inside the frame, fix the front panel;
• cut the removed glass with a glass cutter according to the dimensions taken, install it inside the reduced opening;
• joints must be sealed;
• if a drain hose is needed, install it;
• connect to the electrical network;
• test the device by doing a test run.

The main mistakes when installing plastic windows with your own hands

If you install plastic windows incorrectly, this can lead to the fact that it will be cold in the house, water will flow into the room through improperly installed ebbs. And the expensive structures themselves will quickly become worthless. And if professional installers sometimes make mistakes when installing PVC windows, then an amateur who installs plastic windows with his own hands is certainly not immune from them.

Let's look at the 10 most common mistakes that are made when installing plastic windows.

Window size is wrong

Usually this is a consequence of incorrect, careless measurement of the window opening, and, accordingly, the manufacture of an unsuitable window structure. And in case the window is too big in size. And if the size is very small, it is simply impossible to install such structures.

Poor window preparation

If the surfaces are poorly cleaned, construction debris, dust, potholes remain on them, or, on the contrary, parts of the wall protrude on the surface of the opening, the mounting foam will not stand up as tightly and evenly as it is necessary for a high-quality installation of plastic windows with your own hands. In addition, this kind of pollution absorbs moisture very well, and it will soon be inside your apartment.

Ignoring wall insulation

If the plastic window is installed without taking into account the thermal insulation of the wall, then cold air will penetrate into the apartment at the joints. Therefore, it is necessary to take into account the layers of the walls when installing plastic windows. If the wall consists of one layer, the window should be placed exactly in the middle of the wall. If the wall is two-layer, the window should be installed at the very edge, as close as possible to the insulation. And if the wall is three-layer, then it is necessary to install a PVC window directly in the wall insulation plane, in order to avoid heat loss.

Incorrect distance between the window frame and the slope

If the window frame is located too close to the slope, then the seal in this place will be of poor quality, and moisture will begin to appear and accumulate in these places.If the frame, on the contrary, is located too far from the slope, then there is a risk of deformation, since the load on the anchors or metal plates is too great.

Wrong sill size

The window sill should be somewhat narrower than the window frame itself. If it is of a different size, or it was decided not to install it at all, then water will penetrate under the window frame due to the lack of a normal seal in this place, and as a result, the wall will constantly be wet. Metal parts can simply corrode after a certain time.

Poor quality fixing of the PVC window to the wall

If you feel sorry for the dowels or anchors, and there are too few of them to attach the window structure to the wall properly, over time the position of the window will change, the frame will deform, and it will be difficult for you to open and close the window.

Not enough mounting foam

Polyurethane foam is practically the only material for insulating a window structure and the wall itself to which it is attached. If there is not enough foam, then the heat will go away. Therefore, the gap between the slope and the window frame must be filled properly, not sparing the mounting foam.

No duct tape

If you decide not to use the insulating tape laid down in accordance with GOST on the inside and outside of the window structure, be prepared for the fact that the thermal insulation will gradually become worse and worse. Accordingly, the windows will become unusable much faster than you would like.

Therefore, if you decide to install a plastic window with your own hands, try to go through all the necessary steps and perform all the necessary actions efficiently, accurately and slowly.Then your beautiful do-it-yourself plastic windows will delight you and your household for many years.

Do-it-yourself window air conditioner installation

Choosing a place to install a window air conditioner

You can install a window air conditioner in any room where there is an outlet and a window.

It is very important that the cord from the climatic equipment can be extended to the outlet so that there is no need to use extension cords and adapters.

When placing your window air conditioner, try not to place it near lamps or a TV because most home appliances are sensitive to thermostats. If you place the air conditioner near any household appliances, then it will work more than necessary.

Do-it-yourself installation of a window air conditioner is carried out after a detailed study of the installation instructions.

The procedure for installing a window air conditioner

Installing an air conditioner with your own hands consists of several stages. To begin with, a hole of the required parameters is made in the window, which should be slightly larger (up to 1 cm) than the size of the air conditioner unit.

Further in the opening, it is necessary to install a profile structure, the shelf width of which is 3-4 cm. This will be the frame for the air conditioner. Use mounting foam to seal the gaps between the profile frame and the air conditioner. All cracks must be hidden, while the level of the air conditioner must not be disturbed. When part of the air conditioner is outside, the device is located correctly.

WINDOW AIR CONDITIONER INSTALLATION DIAGRAM

After the device is already installed, you can turn it on to the network and check the performance of the "window" in all modes.Remember, in order to provide maximum protection of the air conditioner from precipitation and pollution, it is necessary to install a metal visor above the unit.

Other corrugation connection options

We examined in detail the best option for venting the duct - into the hole in the window.

But there are other solutions as well. All of them are less successful, and now we will explain why:

1. Conclusion of the corrugation in the window, transom or ajar window. This is often done by everyone who does not get around to equipping a more acceptable unit. Cons - the heated air immediately returns back to the room, the efficiency of the unit drops.
2. Air duct outlet through the balcony door. A bad option if the balcony is glazed, if not, the disadvantages are the same as in the solution with a window.
3. Connecting a pipe to a hole punched in the wall. An acceptable option if you provide maximum thermal insulation.

The last solution is suitable if the mobile air conditioner is used constantly.

To drill a wall of concrete or foam blocks, a long-head hammer drill and a vacuum cleaner are used to remove debris. 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 a “cork” from a heater, or you can put a replacement - a ventilation valve.

In private houses, sometimes there are windows with lifting or sliding sashes. They are convenient for the output of the air duct - the sash is moved away, and a panel of plastic or plexiglass is inserted in its place.

In the plastic panel, just as described in our instructions, a hole is cut out, then an adapter or diffuser is inserted into it, and already into it - the duct pipe

Any option is suitable if the heated air remains outside and does not return to the room through open windows or doors.

Before choosing and installing a mobile air conditioner at home, be sure to consider the installation nuances.

What document regulates the process of installing plastic windows?

In March 2003, GOST 30971–2002 was developed and adopted, which ensured the formalization of installation work. The adoption of this document was facilitated by the state program to increase energy efficiency and energy saving.

But not all companies in their work are guided by the provisions of this document. The high requirements imposed by GOST 30971–2002 increase the costs of firms operating in the PVC window market. Therefore, small companies often ignore its provisions, saving on the quality of services provided. This is facilitated by the low professional level of employees of such enterprises.

To the average layman, familiarity with this document will bring tangible benefits. Knowing the rules for installing PVC windows, he will be able to control the entire installation process, and after its completion he will be able to receive detailed technical documentation on the work performed and full warranty service.
