Methods of Installing Split Air Conditioners

3 minutes, 25 seconds Read


Air conditioners have evolved over the years, providing enhanced comfort and energy efficiency. Among the various models available in the market, split air conditioners stand out due to their flexibility, efficiency, and the convenience they offer in installation. Unlike traditional central systems, split air conditioners, as the name implies, comprise two main components: an indoor unit and an outdoor unit. This essay delves into the methodologies and processes involved in installing split air conditioners.

Understanding Split Air Conditioners

Before diving into the installation process, it’s crucial to comprehend the fundamental structure of split air conditioners:

Indoor Unit: This is the evaporator component that takes in warm air from the room and returns cool air back into the environment.

Outdoor Unit: Positioned outside the home, this unit houses the compressor and the condenser. It expels the heat taken from the indoor air.

Refrigerant: A chemical medium that cycles between the two units, facilitating the cooling process.

Connecting Pipes: These pipes, often made of copper, connect the indoor and outdoor units, allowing the refrigerant to flow between them.

Selecting an Appropriate Location

Choosing the right spot is paramount for the effective functioning of a split air conditioner:

Wall Strength: Says air conditioner installation katy tx the wall chosen for the indoor unit should be robust enough to bear its weight.

Accessibility: The chosen location should be easily accessible for cleaning and maintenance.

Height from Ground: Ideally, the indoor unit should be installed at least 7 to 8 feet above the ground for optimal cooling.

Tilt Angle: The outdoor unit should be placed with a slight tilt to ensure efficient drainage of condensed water.

Installation of the Indoor Unit

Mounting the indoor unit requires precision and attention to detail:

Bracket Placement: Firstly, the mounting bracket needs to be affixed to the wall. It’s crucial to ensure that the bracket is levelled.

Drilling: A hole of about 3 inches in diameter should be drilled on the wall to fit the piping. This hole should be made slightly slanting outward for better drainage.

Setting Up: The indoor unit should then be mounted onto the bracket, ensuring that it’s firmly in place.

Connections: Electrical and refrigerant connections should be made as per the manufacturer’s instructions.

Installation of the Outdoor Unit

The outdoor unit’s positioning determines the efficiency of heat expulsion:

Distance from Wall: Ideally, the unit should be positioned 12 inches away from the wall to ensure unhindered airflow.

Surface: Says 24sevenac the unit should be placed on a flat and rigid surface. This is crucial to reduce vibrations and noise.

Protective Measures: Installing a shade over the unit can protect it from direct sunlight and rain, enhancing its lifespan.

Connectivity: Just like the indoor unit, electrical and refrigerant connections should be made, ensuring they’re tight and secure.

Refrigerant Pipe Connection

Connecting the pipes is a critical step in the installation process:

Measurement: Accurately measure the distance between the indoor and outdoor units to cut the pipes accordingly.

Insertion: Pass the cut pipes through the drilled hole, ensuring they reach the outdoor unit.

Connection: Connect the pipes to the corresponding pipes in the outdoor unit, ensuring a snug fit.

Sealing: It’s imperative to seal the hole in the wall where the pipes pass through to prevent water ingress and to insulate the pipes.

Testing the Installation

Once everything is in place, the system must be thoroughly tested:

Refrigerant Pressure: The pressure levels should be checked to ensure they’re as per the manufacturer’s specifications.

Electrical Tests: The electrical connections should be tested for proper grounding and voltage levels.

Operational Check: Switch on the system to check if it’s cooling effectively. The airflow and temperature levels should be monitored.

Noise Levels: Both the indoor and outdoor units should operate with minimal noise.


Installing a split air conditioner is a process that demands precision, understanding, and care. While many might opt for DIY methods, considering professional installation might be a wise choice due to the intricacies involved. Proper installation not only ensures the efficient functioning of the system but also prolongs its operational life, ensuring comfortable and cool environments for years to come.
