PART ONE: Defining split system air conditioning

What is split system air conditioning?

A split system air conditioning consists of two main components: an indoor unit and an outdoor unit.

The indoor unit is responsible for cooling the room, while the outdoor unit houses the compressor and condenser. The two units are connected by refrigerant lines. Split systems are popular for their energy efficiency, quiet operation, and ability to cool individual rooms or zones.

Many people mistakenly correlate wall-mounted air conditioning units exclusively as split systems.

However, the fact is that any type of system (whether that be a wall-mounted unit or a ducted system) contains both indoor and outdoor components.

Having said that, most people associate split systems with the wall-mounted version. For clarity in this blog post, we will do the same. 

What is the difference between a wall-mounted split system and ducted air conditioning?

Wall-mounted split air conditioning systems cool individual rooms or zones.

Ducted systems, on the other hand, distribute air through a network of floor or ceiling ducts to multiple rooms.

Split systems may be more cost-effective for cooling specific areas, while ducted systems are suitable for whole-house cooling. Consider factors like budget, space availability, and cooling requirements when choosing between the two. Here’s a detailed breakdown of the difference between split system and ducted aircon.

When would you choose a split system over ducted air conditioning?

Split systems are ideal for smaller spaces, apartments, or if you are confined by installation limitations. Choose a split system when you want to cool specific rooms or areas. 

They provide flexibility, allowing you to cool only the areas you need. This is often (somewhat mistakenly) compared to ducted systems, which can cool the entire house.

Note that many modern ducted systems are equipped with clever zoning technology. This gives users greater control over the rooms in the home they wish to cool. 

Having said this, both split and ducted systems allow precise cooling (and heating).

Choosing the best solution for your home often comes down to budget as well as the configuration of your home. This can include roof access, whether it is single- or double-storey, and the angle of the roof.

Remember that both split and ducted systems are exceptional solutions for your home. Each works differently and meets different needs. Our skilled team can help you decipher the best solution when choosing between a split system and ducted air con system

What is a multi-split system?

A multi-split air conditioning system is a type of split system that connects multiple indoor units to a single outdoor unit.

This enables you to cool multiple rooms or areas independently, each with its own temperature control. It offers flexibility, efficiency, and the ability to customise cooling solutions for different areas of your home.

Multi-split is a fantastic solution for when you want the flexibility of a ducted system throughout multiple rooms in the home, but limitations prevent you from traditional ducted installation.

PART TWO: The split system installation process

Split system air conditioning is a popular choice for residential and commercial spaces due to its versatility and energy efficiency. As mentioned earlier, split systems consist of two main components: an indoor unit and an outdoor unit.

The indoor unit, commonly known as the evaporator or air handler, is responsible for cooling the air inside the space. The outdoor unit, known as the condenser, releases the heat collected from the indoor unit to the outside environment.

Do you think a split system could be the right choice for you? We invite you to book an on-site consultation with a member of the Tri-Tech team. We can conduct a detailed site inspection to determine the most suitable location for installation.

Factors such as accessibility, available space, structural considerations, and airflow patterns will be taken into account during this stage. By carefully planning the installation process, we ensure that your split system air conditioner is optimally positioned. This promotes efficient cooling and minimises any potential issues.

The split system installation process involves several intricate steps that our skilled technicians handle with precision and expertise. Here’s a breakdown of the installation process:

Step 1: Mount the indoor unit

The indoor unit is securely mounted on an interior wall. Our technicians ensure that the unit is positioned correctly, allowing for proper airflow and easy maintenance access.

Step 2: Install the outdoor unit

The outdoor unit is strategically placed in an area where it can expel hot air effectively. Our team considers factors such as noise reduction, vibration isolation, and compliance with local regulations during the installation.

Step 3: Connecting refrigerant lines

Copper refrigerant lines are carefully installed to connect the indoor and outdoor units. These lines allow for the flow of refrigerant, enabling the cooling process.

Step 4: Electrical connections

Our qualified electricians handle the electrical connections, ensuring the system is wired correctly and operates safely. Safety is a top priority for us, and we adhere to all relevant electrical codes and regulations.

Step 5: Testing

Once the installation is complete, our technicians thoroughly test the system to ensure it is functioning optimally. They check for proper airflow, refrigerant levels, thermostat calibration, and overall performance to guarantee your satisfaction.

Are split systems easy to install?

Split systems offer a range of advantages, from energy efficiency and quiet operation to individual temperature control. One of the best advantages for trades and homeowners alike is easy installation, too.

The installation process is generally simple, especially when compared to ducted air conditioning, whose process can be much more intricate. Since each unit operates independently, split systems also allow for easier maintenance and repair.

What size system do you need?

The size of your split system should be determined by factors like room size, insulation, and heat load. An undersized unit will struggle to cool the room effectively, while an oversized unit may cycle on and off frequently.

Unsure what size you may need? Our handy air conditioning size guide can help you understand what type of system you may require.

This is a fantastic starting point, but remember to always consult with a professional to ensure proper sizing for optimal performance.

How can you choose an efficient, effective system?

As temperatures rise, the need for efficient air conditioning becomes crucial. Homeowners with split system air conditioners often wonder about the energy efficiency of their cooling systems.

While many assume that split systems are inherently more energy-efficient than ducted air conditioning, it’s essential to strike a balance between efficiency and performance.

The importance of system design

We talk about it often, but the fact of the matter is that we simply cannot underestimate the importance of system design when planning an efficient air conditioning installation

Factors such as room volume, sunlight exposure, insulation quality, ventilation, and appliance usage should be taken into account. Even though split system installations may be less complicated than ducted systems, a well-designed installation is still crucial for optimal performance.

The importance of choosing a skilled and qualified team for split system installation

Select a qualified and experienced team for the installation process. They should have expertise in split system installation, including proper placement, refrigerant line connections, electrical connections, and testing.

PART FOUR: Common split system problems

Below are some of the most common signs that you’re due for a split system service.

The best way to keep a safe and effective system is to organise annual cleans. These keep your unit free of dirt, mould, and dust, promoting better air quality and a more efficient, effective system.

Prioritise regular maintenance and timely repairs to ensure optimal performance and longevity of your split system.

Refrigerant leaks

Refrigerant leaks can occur due to ageing components, poor installation, or physical damage.

Signs of a refrigerant leak include reduced cooling performance, hissing sounds, or ice formation on the indoor or outdoor units.

Your local aircon technician should be called to locate and repair the leak and recharge the refrigerant.

Faulty sensors

Sensors are responsible for detecting temperature changes and signalling the unit to adjust cooling output.

If the sensors malfunction, the system may not cool the room properly or may cycle on and off frequently. This puts unnecessary strain on your unit.

A technician can recalibrate or replace the faulty sensors to restore proper operation.

Compressor problems

The compressor is the heart of the split system, and issues with it can cause inadequate cooling or complete system failure.

Problems may arise due to electrical faults, refrigerant issues, or mechanical failure. 

Compressor problems require professional assessment and repair, which may involve component replacement.

Weak airflow and fan motor failures

Fan motors circulate air over the evaporator coil to cool it and distribute cool air into the room.

If the fan motor malfunctions, the unit may produce warm or weak airflow. Faulty bearings, worn-out belts, or electrical issues can lead to fan motor failures. A technician can diagnose and replace the faulty motor if necessary.

Electrical issues

Electrical problems can disrupt the operation of a split system.

This can include issues with wiring, circuit breakers, or control boards. Symptoms may include frequent tripping of breakers, failure to start or stop, or erratic behaviour.

Only a qualified technician should handle electrical repairs to ensure a safe and proper resolution.

Condensate drainage problems

Improper condensate drainage can lead to water leakage, mould growth, or system shutdown.

Clogged or incorrectly installed drainage pipes, blocked drain pans, or improper unit angles can cause these issues.

Cleaning or unclogging the drainage system and ensuring proper installation can resolve drainage problems.

Thermostat malfunctions

Thermostat malfunctions can result in inaccurate temperature readings, improper cooling, or failure to start or stop the system as intended. Issues may be related to sensor calibration, wiring problems, or control board failures.

Resetting the thermostat or replacing it may be necessary to restore proper functionality.

Noisy operation

While split systems are generally quiet, unusual or excessive noise can indicate underlying issues.

Noises like grinding, squealing, or rattling could be due to loose components, damaged fan blades, or motor problems. Let our team identify the source of the noise and perform the necessary repairs or replacements.

If you encounter any of these common split system problems, consult Tri-Tech for expert advice, proper diagnosis, and prompt resolution.
