7 crucial pointers for installing split air conditioners

Installing a split air conditioner is a significant task. Your air conditioner will provide the best cooling if the installation is done correctly, but if it isn’t, you won’t experience the intended cooling. Poor air conditioner installations also result in a lot of maintenance issues.

Several things need to be taken into account while performing a split air conditioner installation:


  • Wall’s ability to support the AC:

The split AC’s interior unit needs to be mounted on a wall that can support the unit’s weight.


  • Proper distance between the wall and the air conditioner

Split AC indoor units need at least 15 cm of clear space on all sides and the top to ensure optimal airflow.


  • Suitable installation height from the ground:

For adequate cooling within the room, mount the split AC indoor unit at a height of 7-8 feet above the ground.


  • Correct tilt angle of the indoor unit:

Be careful to give the aluminum bracket a tiny tilt angle when mounting it to the wall so that the indoor split-AC unit, once installed, will likewise be at a minor angle to allow for unrestricted drainage of collected water from the drain pipe.


  1. Location of outdoor unit:

The outside unit of a split air conditioner should be placed in an open area, such as a terrace, balcony or side wall, where it can be safely and securely accessed for installation and maintenance. Nothing can obstruct the airflow or flow in an open area. This will provide your compressor and condenser a lot of room to operate effectively. Make sure the outside device is not directly exposed to the sun.

If a terrace is not possible, a robust exterior wall that can support the weight of the outdoor unit without obstructing airflow should be used instead.


  • Proper installation of the outside unit:

Split AC’s exterior unit must be set down on a flat, hard surface. The compressor, condenser, fan motor, and other essential split AC parts are contained in this unit. The unit will vibrate significantly if it is not on a flat surface, which can cause copper pipes to break, coolant leaks, and compressor and condenser damage. The vibrating device also creates a lot of noise, which could annoy your neighbors as well as you.

  • The ideal distance between the indoor and outside units:

The proper spacing between the indoor and outdoor units is crucial for cooling. Between the indoor and outdoor split air conditioning units, coolant that is heated to a very low temperature runs through copper tubes. When the refrigerant moves between the units, there is always some loss of cooling action to the atmosphere. Therefore, keep as little space as possible between the interior and outdoor split-AC units to minimize this loss. Split AC units’ interior and outdoor units can be placed up to 15 meters apart from one another.




  • Ensures adequate cooling
  • Ensures the unit performs effectively.
  • Ensures that the appliance uses less energy, which lowers your cooling costs.
  • Reduces the cost of service and maintenance
  • Increases the air conditioner’s durability
