What Is Split System Air Conditioning?

Split system air conditioning is an indoor unit, usually mounted on the wall, and an outdoor unit, placed outside. This is a flexible and efficient way to cool specific rooms or areas in homes and offices. 

This guide will explain how split systems work, installation, costs, how they compare to ducted systems, and how to choose the right size. Along with the different types of split systems like multi-head and inverter models, best practices for unit placement, their lifespan, advantages, and drawbacks. Allowing you to make the decision if a split system is the best fit for your cooling needs. 

How Do Air Conditioners Split Systems Work?

Air conditioner split system operates by transferring heat from inside your home to the outside. It does this through a circulating refrigerant. The indoor unit absorbs heat from the air inside your room and transfers it via the refrigerant to the outdoor unit, which then expels the heat into the atmosphere. This process continues until the indoor air reaches the temperature set on your thermostat. 

How Do You Install a Split System?

Installing the best split system air conditioner is a complex process that usually requires the expertise of a professional installer. At Proven Air we have a team of dedicated specialists ready to assist you with this process. 

Here’s an insight to the several intricate steps involved: 

• Choose the Right Location: We identify an appropriate wall for the indoor unit, ensuring it will have unobstructed air flow. The outdoor unit should be placed close by, often directly outside the same wall. 

• Mounting the Indoor Unit: Our team secure the indoor unit to an interior wall at a height that allows optimal air distribution and easy maintenance. 

• Installing the Outdoor Unit: Then the outdoor unit is positioned in a well-ventilated space, free from debris and sheltered from harsh weather conditions, then mounted on a solid base to minimise vibrations. 

• Connecting Units: Our experienced installers run electrical cables and refrigerant pipes between the indoor and outdoor units. This includes drilling a hole through the wall to route the connections. 

• Refrigerant and Electrical Connections: Our technicians handle the refrigerant and make electrical connections to ensure safety and compliance with local regulations. 

• Testing: Once installed, the entire system will be tested to make sure it operates efficiently and safely, checking for any leaks or technical issues. 

At Proven Air, each step for the proper installation is necessary so that the air conditioner functions efficiently and safely. 

What Is the Price to Supply and Install a Split System?

Generally, prices can range from $1,500 for basic models to over $3000 for high-end units with greater cooling capacities. At Proven Air we can give you a quote that includes both supply and installation. 

The cost to supply and install a split system air conditioner can vary widely depending on the brand, the capacity of the unit, and the complexity of the installation. Contact us directly for more information. 

Split Systems Vs Ducted Systems: What’s the Difference?

The main difference between split systems and ducted systems lies in their structure and installation. Split systems are ideal for cooling or heating one or two rooms, and they do not require ductwork, making them less intrusive to install. 

Ducted systems, on the other hand, are designed to cool or heat an entire house and involve significant installation work, including fitting ducts throughout your home. 

Here’s a visual table summarising the differences between split systems and ducted systems:

This table highlights the key differences in structure and installation requirements between the two systems.  

How Do I Determine the Right Size for My Split AC? 

Choosing the right size for your split air conditioner is key to maintaining efficiency. If the unit is too small, it won’t effectively cool your space; if it’s too large, it’ll use more energy than needed. 

The ideal size for your AC depends on several factors such as the room size, the number of windows and doors, the ceiling height, and the type of insulation you have. It’s a good idea to consult with an energy assessor or a qualified HVAC technician who can help you determine the best capacity for your needs.

Here’s a visual table outlining the factors to consider when determining the right size for your split air conditioner: 

This table helps illustrate how various factors influence the sizing of a split air conditioner for optimal efficiency. 

 What Are Multi-Head Split System Air Conditioners? 

Multi-head split system air conditioners feature one outdoor unit connected to multiple indoor units. 

This setup allows different rooms to be cooled or heated simultaneously but independently controlled, which is particularly useful for multi-story homes or larger properties where different family members may have different comfort preferences. 

What Are Air Conditioner Inverters?

Inverter technology in air conditioners enables the unit to adjust its compressor speed in response to cooling demand. 

This flexibility makes inverter air conditioners more energy-efficient and better at maintaining a consistent room temperature compared to traditional fixed-speed air conditioners. 

Optimal Placement for Indoor and Outdoor Split AC Units

The placement of the indoor unit should ideally be on a wall that is away from direct sunlight and heat sources to maximise efficiency. It should also be placed somewhere that allows for unobstructed air flow. 

The outdoor unit should be installed in a well-ventilated area, typically on a balcony, terrace, or on the ground beside the building. It should be free from debris and sheltered from extreme weather conditions. 

Here are the placement guidelines for both the indoor and outdoor units of a split air conditioning system: 

Indoor Unit Placement: 

• Place on a wall away from direct sunlight and heat sources to maximise efficiency. 

• Ensure the location allows for unobstructed air flow. 

Outdoor Unit Placement: 

• Install in a well-ventilated area such as a balcony, terrace, or on the ground beside the building. 

• Keep the area free from debris and provide shelter from extreme weather conditions. 

What’s the Typical Lifespan of an Air Conditioner?

The average lifespan of a split system air conditioner is about 10 to 15 years. However, this can vary based on the quality of the unit, the frequency of its use, the environment it operates in, and how well it is maintained. We recommend regular servicing, which can help extend the life of your air conditioner.

Main Advantages and Drawbacks of Split Systems

Advantages: 

• Split systems are generally quieter and more energy-efficient. 

• They allow for room-by-room temperature control. 

• Installation is less invasive than ducted systems. 

Drawbacks: 

• They can be more expensive upfront compared to other cooling options like window units. 

• Aesthetically, the indoor unit may not blend seamlessly into every room décor. 

• Each split system only cools one or two rooms, not an entire home. 

Are Split System Air Conditioners Right for You?

Split system air conditioners are an excellent choice especially if you need to cool a specific area of your home without the expense and complexity of ducted air conditioning. 

They are also suitable if you value energy efficiency and quiet operation. However, if you are looking to cool multiple rooms or an entire building consistently, a ducted system might be more appropriate. 

Consider your specific needs, the property structure, and your budget when deciding.
