Choosing a good air conditioning system is important, but its performance does not depend only on power or energy efficiency. The location of the indoor unit can make a big difference to how cool air is distributed throughout your home.
Poor positioning can lead to areas that are too cold, rooms that barely receive any airflow, higher electricity consumption and even constant discomfort. That is why, before installing a split air conditioning unit, it is worth carefully considering where it should be placed.
Below, we go over the main practical tips and the most common mistakes.
1. Choose a position that distributes air efficiently
The indoor unit should be installed in a location where the airflow can reach as much of the room as possible.
In a living room, for example, it is usually more efficient to place the unit on a wall that allows the air to flow towards the centre of the room or towards the more open areas of the property.
The aim is not simply to cool the wall opposite the unit, but to achieve the most even air circulation possible.
2. Avoid directing cold air straight at people
One of the most common mistakes is installing the split unit directly above a sofa, bed, desk or another area where people spend long periods of time.
Being exposed to cold air directly can be uncomfortable, even if the overall room temperature is suitable.
Whenever possible, it is better to position the unit so that the air circulates around the room before reaching people.
3. Installing it high on the wall usually improves cooling
Cold air naturally moves downwards, which is why indoor air conditioning units are normally installed high on the wall.
From this position, the unit can distribute cool air gradually throughout the room.
However, it is also important to respect the minimum distances from the ceiling and side walls recommended by the manufacturer to ensure proper airflow.
4. Do not place furniture in front of the unit
Tall cabinets, shelving, curtains or large pieces of furniture can block the airflow.
When there is an obstacle directly in front of the unit, cooling becomes less efficient and noticeable temperature differences can appear within the same room.
The area in front of the indoor unit should therefore remain as clear as possible.
5. Be careful with heat sources
It is also advisable to avoid installing the indoor unit too close to heat-producing areas, such as large windows exposed to strong sunlight, kitchens, certain appliances or areas with high thermal radiation.
These heat sources may affect the temperature sensor and cause the system to work harder than necessary.
6. The layout of the property matters
There is no single perfect location that works equally well in every home.
In smaller, open-plan properties, one strategically positioned split unit may be able to cool a relatively large area.
However, in homes with long corridors, several separate rooms or doors that are usually kept closed, trying to cool the whole property with a single unit may not be very efficient.
In these situations, it may be more suitable to consider alternatives such as a multi-split system or ducted air conditioning.
7. Do not choose the location based only on appearance
It is understandable to want the unit to blend into the room visually, but hiding it too much can reduce its performance.
For example, installing it inside furniture, between shelving units or in corners with poor airflow can significantly reduce cooling efficiency.
Appearance is worth considering, but only after making sure the unit can operate correctly.
Common mistakes when positioning an indoor air conditioning unit
Some of the most common mistakes include:
- Installing the split unit directly above a bed or sofa.
- Positioning it too close to the opposite wall.
- Blocking the airflow with furniture or curtains.
- Choosing a location simply because it makes installation easier.
- Trying to cool several closed rooms with one unit.
- Failing to consider the orientation of the property and sun exposure.
- Installing a system with unsuitable capacity for the size of the room.
Where should you place air conditioning in a bedroom?
In a bedroom, it is particularly important to avoid directing the airflow straight towards the bed.
A side position or a location that allows the air to circulate above or around the sleeping area is usually much more comfortable.
It is also advisable to adjust the louvers correctly and use night or sleep modes when available.
And in the living room?
In a living room, the aim is usually to choose a position that allows the cool air to reach the largest possible area.
If the living room is connected to a dining area, open-plan kitchen or hallway, the layout of these spaces should be considered before deciding where to install the split unit.
In some properties, moving the unit by just one or two metres can make a significant difference to airflow distribution.
A good installation starts before the unit goes on the wall
The position of the indoor unit should be chosen according to the size of the property, its orientation, room layout, heat sources, insulation and how each area is used.
That is why a professional installation is not simply about placing the unit on the most convenient wall.
At AC Torrevieja, we assess each property to find a position that provides efficient, comfortable cooling adapted to the space.
If you are considering installing or replacing your air conditioning in Torrevieja and the surrounding areas, we can help you choose both the right system and the best location to get the most from its performance.
