5 Best Vertical Window AC For Any Room | Reviews Guide

The window air conditioners are comparatively easier to install, affordable and can be maintained easily. They are more suitable for the smaller rooms than the split AC units or central AC alternatives. So, most people opt for this option but some people do not have the space for installing it. Therefore, the easiest way out is to go for the vertical window AC units.

There are various considerations that you need to look for when buying the vertical window ACs. In the following list, we have discussed the basic factors that you need to look at for making the right choice.

  • Cooling Capacity: The cooling capacity is a primary consideration when you are buying the vertical window AC. BTU is the unit for measuring the cooling capacity for any air conditioners. You should select an AC unit whose BTU is suited according to the size of the room you want to cool as both units with larger and smaller BTU capacities have adverse effects.

  • Coverage Area: The coverage area is the total area that the air conditioner can cool adequately. It is highly influenced by the BTU reading of the AC. However, there are several other factors which influence the required BTU for the air conditioning unit.

  • Noise Level: No one wants an AC which will make more sound than the conversation that is going on in the room, therefore, the range of the noise level of the air conditioners should be between 37 decibels and 82 decibels to be quiet in operation.

More details on the things to consider when buying the vertical window AC units are discussed in the “Buying Guide” given later in the article. We have listed the best vertical window ACs with their most notable features, pros and cons. Check them out to make the best choice.

Things to Consider Before Buying the Vertical Window AC

The vertical window ACs are designed in a way that they are adequate to cool one or multiple rooms at the same time with their sufficient cooling capacity. However, there are several things that you need to keep in mind while you are choosing the ideal vertical window AC for you. We have discussed the basic factors that you must look at before you make your choice in the following section.

1. Cooling Capacity

The first consideration, when you are looking to buy an air conditioner, must be the cooling capacity. The unit for measuring cooling capacity is BTU or British Thermal Unit. For better effectiveness and efficiency, you should select a unit which features a BTU reading that is suited to your space.

If the vertical window AC does not have sufficient BTU, it will continuously try to cool the space up and in the process, consume more power and electricity. If you choose a unit which features a larger BTU, it will leave uncomfortable uneven hot and cold patches of area in the same room.

2. Coverage Area

The coverage area is determined by the sufficient area that can be cooled by the air conditioning unit. This factor is directly influenced by BTU. There is a standard chart which determines how much BTU is required for a certain square foot area of space. For square feet of 300 to 350, 8000 BTU is required while 10,000 BTU is sufficient for 400 to 450 square feet, but while looking at the coverage area, you need to consider several other factors like the ceiling height should be a standard 8 foot for the chart to function properly.

Then, if the room you wish to cool is sunny during the day, then the BTU should be increased by 10%. Alternatively, if it is shaded, then the BTU can be decreased by 10%. If there are more than 2 occupants in the room then the BTU should be increased by 600 for each extra person. If the AC is installed in high-heating areas like the kitchen, then the BTU rating should be increased by 4000.

3. Noise Level

Most people install air conditioners so that they can be used during the nighttime while sleeping. Now, no one wants an air conditioner which makes a noise that can disrupt their sleep. So, you should go for air conditioners that have a noise level between the range of 37 dB to 82 dB. The above-mentioned noise level will not disrupt the conversation and will also be pleasant for any room.

4. Energy Efficiency

Usually, window air conditioning units are more efficient than the central air conditioning system. They are economical options when purchasing, and the maintenance cost is also much cheaper than the central units. For determining energy efficiency, we need to look at two factors.

The first one is the energy star rating which is used to know about the operating expenditure and how much power is consumed by the unit. This factor, in turn, also tells about the money that is saved while operating. The second consideration is the Energy Efficiency Ratio or EER. It is simple to understand as higher EER signifies that the AC unit is more efficient.

5. Type of Controls

There are various kinds of control systems that are available for the air conditioners. They can be controlled through the remote, knob system or through button system. In the remote-controlled system, the control is managed through the remote. In the knob or the button system, the control panel is in the AC unit and can be operated by turning the knob or touching the buttons.

6. Voltage

The vertical window air conditioners are powerful units and require more power than the usual household appliances. You need to make sure that the electrical requirements of the unit are adequately supplied by the existing electric system of the household. Most air conditioners run on 220V, 125V or 115V circuits. The ACs with lesser than 15000 BTU operate on 115 to 125 volts, and anything above that requires 220 volts.

7. Refrigerant

The refrigerants are classified into different groups owing to their chemical composition. After the discovery that some refrigerants are responsible for ozone layer depletion and are harmful to the environment, they are being replaced by eco-friendly alternatives. The newer refrigerants used are hydrochlorofluorocarbons, as they do not contain methane and are not harmful to the ozone layer.

8. Brand

This is a great feature to consider when buying a new vertical window air conditioner. It is recommended to go for well-reputed, tried and tested brands. You need to choose the brand carefully and can also consult your family or friends who have experience with some particular brand.

9. Warranty

An air conditioner must be maintained regularly to ensure its proper functioning. Therefore, investing in an annual maintenance plan is a good idea. Some brands offer free maintenance services during the warranty period. The warranty period also works as a testament for the durability and longevity of the air conditioner, so go for those with a higher warranty period. One more thing to consider here is the pricing of the extended warranty period to enjoy the same benefits for a longer period of time.

Vertical Window AC FAQs

1. Does the vertical window AC need any angle for installation?

Ans: Yes, you need to install the vertical AC unit at a tilted angle so that the water can run down easily when the Ac is running. As the drainage system is already installed in the machine, the tilted angle will accelerate the process of getting rid of water.

2. At which place in the room the vertical AC can’t be installed?

Ans: You should avoid installing vertical AC in places where the heat is direct to the unit. So you should avoid places which come in direct contact with the sunlight.

3. At what height the vertical window AC can be placed?

Ans: When placing the window AC vertically, it should be installed at a height of 3 to 4 feet above the ground.

4. Does my air conditioner use a lot of electricity?

Ans: The 1 ton air conditioner uses near about 0.5 to 1 unit of electricity in each hour.

Summary
The above are a few examples of window air conditioner units that can fit into a window that slides side-to-side or a vertical window that is narrow and tall.

Vertical window AC units are not common, but a few are available.

The two main things to keep in mind when buying a slider air conditioner unit are the dimensions and the power needed.

Be sure to measure the window the unit will be placed in to be sure it can fit and match them to the unit’s size.

Also, the correct power outlet needs to be provided, or the unit can not work. While most are 115 volts, some come larger packages come with 220 volts which is not a common wall outlet.

Two hundred twenty volt units can provide more cooling capacity but will need a power line to run it. A 220-volt line can be run to a unit but will cost more money if one does not already exist.

Most 220 volt outlets in a home are set up for an electric water heater or electric clothes drier.

Keep in mind there are other options to cool a room, such as a Mini Split unit or a portable system which are popular.

Portable and mini-split units often cost more but have their benefits over a standard window air conditioning unit.

For example, a portable unit can be moved to any room and use a large hose to pump out hot air from a room. This makes them more versatile and easy to set up.

A mini-split unit is built to last a long time and fit into a home nicely by not taking up much space. They are quieter also since the main components are located away from home.

Vertical windows in Moscow from the manufacturer

The company “Windows Prosvet” offers vertical sliding windows. Their main difference from the usual hinged window structures is the vertical opening. With the help of clamping mechanisms, the window sash is fixed in a predetermined position, and while moving along the guides, it does not require free space in front of the window.

This type of glazing was originally used in the UK. Gradually, with the conquest of new lands, English windows became popular across the ocean – in America and Australia.

Previously, wood was used for production, now plastic or aluminum profiles are used for the manufacture of frames, and double-glazed windows are installed instead of glasses.

Benefits of the

system

Vertically sliding glazing is durable, wind-resistant and an unusual addition to the architecture of the building. English-style windows are also characterized by the following:

  • absence of dead zones during ventilation;
  • the ability to use the entire area of ​​the window sill;
  • high degree of protection against intrusions and doors opening by children;
  • attractive appearance and significant space savings.

By firmly fixing the sash, you can control the volume of fresh air entering the room during ventilation. The use of plastic profiles makes vertical sliding windows more functional. They reliably protect against cold air masses and extraneous noise, are easily cleaned of dirt and are designed for a long service life.

These windows look harmoniously with the interior in a classic style, and with modern furnishings. Installing double-glazed windows with certain properties allows you to create comfortable conditions in the room.

Glazing options

Vertical lift windows are available in two versions. The Single Hung system coincides with traditional English glazing, in which only one sash is movable. When opened, it moves slightly towards the main one. The imitation of windows in the English style includes the glazing of the Double Hung modification, in which both wings are movable.

Depending on the design features, vertically lifting glazing can be:

  • Single sash . This type is more common in Europe, due to the architectural features of buildings. For single sash windows, the sash rises to the outer wall.
  • Double leaf . In this case, the glazing design follows American windows and consists of two sashes, as in the classic Single Hung system. One of them is stationary and rigidly fixed, and the second mobile one moves along the first one.

Three-leaf designs provide for the possibility of opening the leaves with a vertical movement towards each other. A fixed sash is installed in the middle of the plastic window, and movable sashes are installed above and below. To prevent a sharp fall of the frame elements, the sliding mechanism is equipped with reliable brakes.

When choosing a specific glazing option, the nuances of the building architecture, the maximum allowable weight of structures and other factors are taken into account.

Characteristic differences of fittings

Fittings for a vertical slider significantly differ from the mechanisms for opening standard plastic windows. It does not have hinges, does not provide for handles or is equipped with models that are almost invisible.

The doors move vertically, so a special mechanism with skids is installed for movement, which can have a smooth sliding surface or be supplemented with small wheels.

American vertical slider windows. Design and price in Moscow

Vertical sliding windows are becoming more and more in demand in the Russian market. This fact is explained by their original way of opening, exclusive type of construction and advantages of use.

In the InWood company, you can order American slider windows made of wood or plastic. The price of American sliding windows is calculated at the request of the client, and depends on the area of ​​the opening, the type of system and other factors.

What are American sliding windows

Window structures of this type are used in America and England. They are popular due to ergonomics, reliability, ease of ventilation. Surely you have seen such windows in films, where the heroes of the tape move the frame up with a little effort.

Today, the design of the sliders has become more perfect, the frame moves more smoothly, it moves on special carriages. When the sash is opened, its sharp lowering down is completely excluded – it is securely held by spring mechanisms at any height.

Design options

Wooden or plastic slider windows are made in two versions: Single Hung and Double Hung systems.

In the Single Hung system, only one leaf rises, the second remains motionless, deaf. When opened, it slides slightly over the main frame.

The Double Hung variation involves the alternate movement of both wings – ventilation is combined from above or below. According to the type of movement, the system frames are divided into horizontal slider windows and vertical ones.

How it works

In order to open the window, you need to turn the handle (it is also a locking mechanism), then pull it towards you and raise the sash. Unlike other options that use pressure locks, in our types of designs, it takes only one movement to open the window, not three.

Thanks to special guides and carriages, which can be seen in our video, the movement of the sash is incredibly smooth, without any effort. Watch the video where our specialist demonstrates the work of the window.

Slider window before installation in the house

Where US Slider Windows Are Used

Due to the ergonomics of the windows, due to the movable rather than hinged opening principle, the structures can be used in any premises where space is limited or such an opening principle is needed.

Sliding windows slider can be installed:

  • In apartments, for glazing balconies, loggias, rooms;

  • In cottages and private houses, in bay windows, on the ground floors, in rooms. It is especially convenient to install such structures in kitchens that are combined with a veranda, where it is customary to dine and receive guests. In this case, by opening the window, the hostess can quickly serve snacks and drinks to the site without leaving home.

  • In fast food cafes, convenience stores, kiosks. Windows can be equipped with anti-vandal and anti-burglary fittings, which will prevent intruders from entering;

  • In any buildings and structures that require ergonomic designs that save space and do not require special maintenance.

Sliding sliding windows are safe and suitable for installation in homes with small children. If desired, the lower sash can be closed using a special plug, and it will be impossible for a child to open it. The plug can be removed at any time.

Benefits

More and more often you can find positive reviews about slider windows, this is due to their merits:

  • Space saving.
    To open the frame, you do not need to release the window sill – remove flower pots or decor items, the windows will not tear the curtains, as they move up. The sash does not go beyond the window sill and you can use the space near the wall without restrictions – now it will be easy to put a dining table close to the window sill, a sofa, etc.;

  • Excellent ventilation.
    Thanks to the unique design, more air enters the room, and the air exchange process itself is much more efficient than in traditional swing systems;

  • Attractive look.
    The system looks incredibly aesthetically pleasing, the decorative layout inside the double-glazed window gives it a special chic. Vertical sliders blend perfectly with any architectural style and building exterior, making it even more beautiful;

  • Easy care.
    To wash American plastic or wooden “slider” windows, it is enough to open the frame towards yourself. Therefore, the process of maintaining the structure is absolutely safe, regardless of the height of the building;

  • Wind resistant.
    Slider windows will never slam shut even from strong winds, as they are equipped with a reliable locking mechanism, and the sliding vertical system has no windage and does not react to drafts;

  • Energy efficiency and soundproofing.
    High-quality sliding systems are 4 times warmer than traditional ones, since instead of the usual reinforcement, a special filler is used that increases the thermal insulation properties, as well as enhances sound insulation.

  • Lightweight sashes.
