When it comes to keeping your home comfortable, a split system air conditioner can be an excellent choice. Split systems, also known as ductless air conditioners, offer many advantages, including energy efficiency and customised climate control. However, with various options available in the market, choosing the right split system for your home can be a daunting task. In this buyer’s guide, we will walk you through the key factors to consider to make an informed decision and create a comfortable living space.

Understanding Split Systems

A split system air conditioner consists of two main components: an indoor unit and an outdoor unit. These units are connected by a refrigerant line and electrical wiring. The indoor unit is typically installed on a wall or ceiling, while the outdoor unit is placed outside the home. Together, they work to provide efficient cooling and, in some cases, heating.

Assessing Your Needs

The first step in choosing the right split system for your home is to assess your specific needs. Consider factors like the size of the area you want to cool, the climate in your region, and your budget. It’s crucial to determine the cooling capacity required to adequately cool your space, as an undersized unit won’t provide sufficient comfort, while an oversized unit may be inefficient.

Energy Efficiency

Energy efficiency is a critical factor to consider when purchasing a split system. Look for units with a high SEER (Seasonal Energy Efficiency Ratio) rating, as this indicates greater energy efficiency. More efficient systems can help you save on electricity bills and reduce your carbon footprint.

Indoor Unit Types

There are several types of indoor units to choose from, including wall-mounted, ceiling cassette, floor-mounted, and concealed duct units. The choice of indoor unit will depend on your preferences and the layout of your home. Wall-mounted units are popular for their ease of installation and quick cooling, while ceiling cassette units offer a more discreet appearance. Floor-mounted units are ideal for spaces with limited wall and ceiling space, and concealed duct units are hidden in the ceiling, offering a seamless look.

Outdoor Unit Location

The placement of the outdoor unit is also a crucial consideration. It should be situated in a location that allows for proper airflow and minimal obstructions. This can impact the efficiency and longevity of the system. Additionally, consider factors like noise levels and aesthetics, as the outdoor unit should not disrupt your outdoor living space or create an eyesore.

Maintenance and Filter Options

Split systems require regular maintenance to ensure optimal performance. Look for models with easy-to-access filters that can be cleaned or replaced without much hassle. Proper maintenance not only keeps the system running efficiently but also improves indoor air quality.

Split System Installation Cost

Split system installation cost can vary significantly depending on factors such as the size and complexity of the installation, the brand and model of the system, and your location. It’s advisable to obtain multiple quotes from reputable HVAC contractors to compare costs. Keep in mind that while installation costs are a one-time expense, choosing a more energy-efficient system can lead to long-term savings on your energy bills.

Warranty and Support

When purchasing a split system, it’s essential to consider the warranty and after-sales support provided by the manufacturer. A robust warranty can provide peace of mind and save you money on potential repairs. Additionally, check if the manufacturer or installer offers maintenance packages to keep your system in top condition.

Environmental Impact

In today’s world, it’s crucial to consider the environmental impact of your choices. Look for split systems that use eco-friendly refrigerants and have energy-efficient features. Some models are designed to minimise their carbon footprint, making them a responsible choice for environmentally conscious homeowners.

Consult with a Professional

While this guide provides essential information to help you make an informed decision, consulting with a professional HVAC contractor is highly recommended. They can assess your specific needs, recommend the most suitable system, and provide accurate installation cost estimates based on your home’s layout.


In conclusion, choosing the right split system for your home is a significant decision that can impact your comfort, energy bills, and the environment. By assessing your needs, considering energy efficiency, indoor unit types, and outdoor unit placement, and factoring in maintenance and installation costs, you can make an informed choice. Remember to prioritise environmental responsibility and seek professional guidance to ensure you select the perfect split system for your home. With the right system in place, you can enjoy a comfortable and energy-efficient living space for years to come.
