Where Not To Position Your Air Conditioning Unit

Before diving into the positions you should place your AC on, you must look into the places you shouldn’t consider for your AC installation:

1. Directly Above the Door

Installing your AC directly above the door can be your worst decision. When you open the door, it lets the conditions air out of your room.

Maintaining your room temperature for a long when the AC is placed above the door will be hard.

2. Near a Heat Generating Appliance

Another place that you should avoid placing your AC unit is near a heat-generating appliance like a refrigerator.

Moreover, you should also avoid placing it over your TV because an air conditioner can sometimes also produce moisture that will probably get into your TV, temporarily or permanently damaging it.

3. Facing the Window

Windows are the areas that come in direct contact with sunlight in your room.

When you place your AC in front of the window, it will most likely suffer an overload because it will keep operating without being able to lower the temperature, as the sun will also be working on increasing the temperature simultaneously.

Ideal Places To Fit Your AC

Now comes the part where you must decide which area to go for. You can choose any place from any of the following places to make your AC system work efficiently.

1. Wall Adjacent to Your Bed

Many prefer installing their system over their beds, which is also very common. It is to make your experience more comfortable and better.

However, not many people realize they can negatively impact your sleep because when the AC emits any liquid or moisture, it will affect your sleep.

2. Place on the Longer Wall in a Rectangular Room

If you have a rectangular room, the long wall is the best place for an AC. The long wall provides a free air overflow compared to the short wall.

Free air overflow is impossible when the AC is placed on the shorter wall.

3. Select a Place With Optimum Height

The optimum height for an AC to be placed on a wall is neither too high nor too low. It would help if you placed it on a medium level to remain approachable for the technicians and even for you for technical purposes.

It becomes unapproachable for the technicians and a hassle if it’s too high.


You should leave over 15 cm from the ceiling when placing an AC system.
