Choosing The Right Split System Air Conditioner For Your Home

When the temperature soars, a reliable air conditioning system can make all the difference in maintaining a comfortable home environment. Split system air conditioners are a popular choice due to their efficiency, quiet operation, and ability to cool or heat specific areas. However, with so many models and features available, choosing the right split air conditioner for your home can feel overwhelming.


This guide will walk you through the key factors to consider when selecting a split AC, comparing different models and features, and exploring the benefits of this type of air conditioning system.

Factors to Consider When Choosing a Split AC

Choosing a split system air conditioner involves more than just picking a brand or model. Homeowners should consider several factors, including the size of their space, energy efficiency, smart features, and overall performance. Making an informed decision can help ensure optimal cooling and heating without excessive energy consumption or maintenance issues.

Room Size & Cooling Capacity

One of the most important factors when selecting a split system air conditioner is ensuring it has the right capacity for the space you want to cool. Air conditioners are measured in kilowatts (kW), and choosing the correct size is essential for efficiency and effectiveness.


  • Small rooms (up to 20m²) – 2.5kW
  • Medium rooms (20m² – 40m²) – 3.5kW – 5kW
  • Large rooms (40m² – 60m²) – 5kW – 7kW
  • Open-plan areas (60m² +) – 7kW and above


If you choose a unit that’s too small, it will struggle to cool the space effectively, leading to increased energy consumption. A unit that’s too large may cool the room too quickly without removing enough humidity, leading to a damp and uncomfortable environment.

Energy Efficiency

Energy efficiency is a crucial consideration, as air conditioning can significantly impact electricity bills. Look for a split system with a high energy star rating. More stars indicate better efficiency, helping you reduce running costs and environmental impact.


Many modern split systems also feature inverter technology, which adjusts the compressor speed based on cooling demand, resulting in more efficient operation and lower energy consumption.

Cooling & Heating Capabilities

Some split systems are cooling-only, while others offer reverse-cycle technology, meaning they can both cool and heat your home. A reverse-cycle split system is a great investment if you need an all-season solution.

Air Quality Features

If air quality is a concern, look for split air conditioners with built-in filters that can remove dust, allergens, and even bacteria from the air. Features such as ionisation, HEPA filters, and plasma filters can help improve indoor air quality, making them ideal for households with pets.

Smart Features & Controls

Many modern split system air conditioners come with smart features, including:


  • Wi-Fi connectivity – Allowing you to control the system remotely via an app.
  • Timer functions – Letting you schedule operation to optimise energy use.
  • Eco mode – Helping to reduce energy consumption.
  • Self-cleaning functions – Reducing maintenance needs and improving efficiency.

Noise Levels

If you’re installing a split system in a bedroom or living area, noise levels are an important factor. Look for models with low dB ratings to ensure a quiet and comfortable environment.

Brand Reputation & Warranty

Choosing a reputable brand with good customer reviews ensures you invest in a high-quality and durable system. Check the warranty terms to understand what is covered, as this can save you from unexpected repair costs down the track.

Comparing Different Models & Features

There are various split system air conditioners on the market, each offering different features to suit individual needs. Here’s a breakdown of how standard and premium models compare:


  • Energy Efficiency: Standard models typically have a 3-4 star rating, whereas premium models can reach 5 stars for better energy savings.
  • Inverter Technology: Both standard and premium models generally include inverter technology, but premium versions often have advanced inverters for greater efficiency.
  • Smart Features: Basic models usually come with a standard remote control, while high-end models may include Wi-Fi connectivity, voice control, and app integration for enhanced convenience.
  • Air Quality: Standard models offer basic filtration, whereas premium options may include HEPA, plasma, or ioniser filters for improved indoor air quality.
  • Noise Levels: Standard air conditioners operate at moderate noise levels, while premium models offer ultra-quiet modes, making them ideal for bedrooms and noise-sensitive areas.

Benefits of Split System Air Conditioners

Split system air conditioners offer numerous advantages for homeowners looking for an effective and efficient cooling and heating solution. These systems provide targeted climate control, helping to create a comfortable indoor environment while keeping energy costs manageable.

Cost Saving

Split system air conditioners, especially those with inverter technology, are highly energy-efficient, helping reduce electricity costs compared to older cooling systems.

Zoned Cooling

Unlike ducted air conditioning, which cools an entire home, split systems allow you to target specific areas, ensuring efficient use of energy.

Easy Installation

Compared to ducted systems, split systems are easier to install as they require only an indoor and outdoor unit with minimal structural modifications.

Quiet Operation

With the noisy compressor located outside, split systems offer a quieter cooling solution, making them ideal for bedrooms and living spaces.

Versatile Options

Whether you need a unit for a small bedroom or a large open-plan space, split system air conditioners come in various capacities and configurations to suit different needs.

Improved Air Quality

Many split systems come with advanced air filtration features, making them ideal for improving indoor air quality and reducing allergens in the home.
