Horizontal vs vertical window air conditioner

Points to be considered before buying vertical sliding/casement air conditioner

If you are seeking to install and fit a casement air conditioner then many different factors should be kept in mind. Some of them are as follows:

Cooling effectiveness

If your air conditioner is not providing enough cooling then, what is its importance?  It means that there should be no compromise on the effectiveness of a casement air conditioner. As the main aim of fitting and installing an air conditioner is to cool your room. But if your air conditioner fails to give adequate coolness and conditioning then, what is its purpose?

Size of room

After checking the effectiveness, you should consider the space and size of the room which has to be cooled by the casement air conditioner. Whether it is a single bedroom or linked room which is further connected to another room. Considering the size is important because the size of the thermal unit is directly proportional to cooling. So if you want to cool a larger space then you will a larger thermal unit.

Way of fitting

As a casement air conditioner has to be fitted in the window, so make sure that the size of the air conditioner and window are comparable. In this process, you have to consider the space provided by your window. So buy the casement air conditioner according to the dimensions of the window.

Weight of the Air Conditioning unit

Not only the size but weight is another factor. The heavier casement air conditioner needs extra support for its installment. Moreover, the installment of the casement air conditioner is a little complicated.

Pros and cons of vertical air conditioners

Every air conditioner has its qualities and some drawbacks. Similarly, a vertical air conditioner also has some pros and cons.

Pros:

  1. If you are seeking to rent your home or apartment then a vertical air conditioner is the best choice without a central air conditioner.
  2. It provides an affordable way to prevent roasting in summer.
  3. The attractive feature of a vertical air conditioner is the customizable nature.
  4. You can select a vertical air conditioner according to your space, window size, cooling capacity, needs.
  5. In addition to the above features, it offers WiFi, remote control, temperature sensor.
  6. No additional installment for water drainage and electrical system is required.

Cons:

  1. They are not much elegant and attractive.
  2. They are usually bulky units
  3. Of course, they are complicated to be installed.
  4. As they are fitted in the window so they need your window to be opened to some extent.
  5. Opening of the window allows hot air to enter the room
  6. You will have to use insulation or another sealing method.

Vertical window AC VS Horizontal AC

Gravity will exert different pressure on the window unit placed in the horizontally opening window and vertically opening window. Most people prefer vertically sliding window as compared to the horizontally sliding window.

A/c unit placed in the vertically-opening window will have more support from both sides. It will be held properly due to this support. Due to lack of support in a/c unit fitted in a horizontally-sliding window, they will usually tip outward.

A/c units fitted in the vertically-sliding window make more sense.

So, if you have to make choice or selection between the horizontal-sliding window and vertical-sliding window always prefer the vertical.

In the case of a horizontally-sliding window, you will have to select a skinner and taller air conditioner.

Problems of the sliding window:

There are some problems associated with a sliding window as follows:

  1. Both windows can’t be opened or slide side by side as the casement sliders will conflict with each other.
  2. The fitting of the window a/c is difficult due to the sashes of the windows.
  3. It results in leaving space on the upper side, hence decreasing the efficiency.
  4. In some cases, the window a/c unit is larger to be fitted in the casement window.
  5. The casement air conditioner should be brought whose size is compatible with that of the window.
  6. A larger casement air conditioner requires more power of electricity.
  7. The rear side of the casement air conditioner should be in a shady place to make it more effective.

1200-140023000
1400-155025000

Size and Weight:

You need the assistance of another person too.  Handling the heavier air conditioner unit is usually a difficult task.

Location:

Before selecting your air conditioner, the placement and location of that air conditioner should be clear in your mind. Moreover, the room or a place which is to be cooled should be considered before the selection of the capacity of the air conditioner. For example, you want to cool a small room or a room on the ground floor then you need a smaller air conditioner unit. But if you want to condition the room on the 1st floor facing the direct sunlight then you will have to select an air conditioner with greater capacity and hence that air conditioner will be heavier too.

  5. Air quality is better
  6. Produce fresh and clean air

Efficiency:

The efficiency of the air conditioner is measured in terms of energy efficiency Ratio EER. EER is the ratio of BTU (cooling capacity per hour) to the power input. EER and efficiency are directly related. The higher value of EER indicates the greater efficiency of the air conditioner.

Level of noise:

AirSpeed:

Some air conditioners have multiple airspeeds but some have usually one type of flow. Multiple airspeeds and multiple flows offer additional comfort but it is not necessary to select a multiple airspeed air conditioner. It only depends on your need for cooling.

People Also Ask

Can you put a horizontal air conditioner in a vertical window?

Should the window air conditioner be tilted?

Some people think that air conditioners should be tilted to drain the water. But you should keep in mind that air conditioners are provided with a proper drain system. Many window air conditioner units are tilted slightly away from the building to ensure condensation in the drip pan. This tilt shouldn’t be larger than half an inch. Some latest units even don’t require tilt because the drip pan is manufactured at a slightly tilted angle.

What happens if you don’t put a window air conditioner in the window?

The window air conditioners are meant to be mounted in the window for proper functioning but they can be placed anywhere for proper conditioning if you maintain the process of venting and capturing the condensate. It is impossible to place the whole unit inside and get cool air because the air conditioner provides conditioned air by expelling the hot air outside. Without a proper system of expelling out the hotter air, it is impossible to condition the room.

They suck the inner air and blow the air into the coils with the help of a fan. Here it is cooled by refrigerant and then conditioned air is sent back to the room. In all this process, it does not pulls air from outside because it is not designed for that.

How long do window air conditioners last?

The lifespan of home air conditioners depends on many factors but commonly they last from 10-15 years.

Do window air conditioners use a lot of electricity?

If you compare a central air conditioner with a window air conditioner in terms of consumption of electricity the window air conditioner uses less than half of the amount of energy as compared to the central air conditioner.
