HomeTriangle Guide: Where To Place Your AC?



We are all initially confused about where to place your indoor AC. With the current constant rise in temperature in most Indian cities in the last decade, air conditioners are no longer a luxury but an essential appliance. One of the most important factors you need to consider when installing an AC in your home is where to place it to maximize its cooling. 

To ensure the efficient performance of your unit and save your energy at the same time, it is absolutely crucial to find the right position for your AC. This article will include how you can have your wall-mounted AC regulate the room temperature effectively by selecting the best place on your wall for your indoor AC unit. 



Here’s HomeTriangle’s guide on where to place your AC to get maximum cooling. 

Check Your Walls




Your first step should be to check whether the wall meets the criteria for installing the indoor AC unit on it. Once you have ensured that the walls pass the test, follow the tips below on the basis of the room. 

AC Placement Tips 




1. Place your air conditioner away from heat sources such as appliances like kitchenware or any external portion that is basked in sunlight. The thermostat will gain a false reading when the unit is placed too close to heat sources and subsequently result in no cut-off of the compressor. 

2. One of the most important things you need to consider when installing the AC is to ensure that there is no interruption in the airflow from the unit. In short, do not place it behind any furniture or doors that could obstruct the airflow from the unit as the interrupted flow can affect the lifespan of the AC. 



3. Indoor ACs have to installed high on the wall to ensure that cool air is distributed evenly throughout the room. Place the indoor air conditioner at a proper height ensuring that it does not block the passageway, ideally about 7 feet from floor level for split ACs. 

4. It is very important to install the indoor AC unit away from electrical appliances as an electrical appliance placed above a split AC can leak water into the unit and cause unwanted trouble.

5. Our experts say that an AC unit placed in the central location of a room can ensure a uniform flow throughout the room. Depending on the range and size of the model, the airflow from the unit falls at a distance of anywhere between 3 and 5 feet, the location of the AC should be governed by the furniture layout, the openings, the size, and the shape of the room. 



  • The indoor AC unit should be preferably placed on the longer wall of a room of rectangular shape to trap the cooling in the room. 
  • It is better to place the split air conditioner so that the flow hits a plain wall instead of hitting a wall that has openings in it as the airflow towards the opening leads to more load on the compressor and power consumption. 
  • It is very much recommended that you place the indoor unit of the air conditioner on the shorter wall if you have a rectangular room with the wall-length twice larger than the width in order to cover the long space of the room. 
  • In case you have rooms of 30 plus feet in length, it is advisable to place two indoor AC units on the same wall as placing them opposite each other can create non-uniform air circulation. 
  • If you have a room that has different areas but not a rectangular-shaped plan, we suggest you install the AC in the larger section of the room. 



It is preferable to receive an indirect flow from AC as a direct flow from the AC can create a discomfort zone. It is also essential to consider the size and capacity of the AC unit to ensure you get the most out of your appliance.
