How To Choose The Right Split System Air Conditioner For Your Home

Airdale Services • March 11, 2025

A split system air conditioner is a popular choice for homeowners looking for an efficient way to cool and heat their space. With its sleek design and ability to maintain comfortable indoor temperatures year-round, a split system can be an excellent investment. However, choosing the right unit requires careful consideration of factors such as size, energy efficiency, features, and installation requirements.


If you’re thinking about air conditioner installation in Wollongong, here’s what you need to know to select the best split system for your home.

Understanding Split System Air Conditioners


When your split AC makes unfamiliar noises, it’s often the first sign of a malfunction that could worsen if not promptly addressed. Here’s why you should contact a technician immediately:


  • Early Warning Signs: Unusual noises typically signal that something within the system is amiss, be it minor wear and tear or a critical malfunction.
  • Cost Savings: Addressing noises early can prevent more extensive damage to your AC unit, saving you money and hassle in the long run.
  • System Longevity: Prompt repairs enhance the lifespan of your AC system, ensuring it serves you well for years to come.

Choosing the Right Size & Power


One of the most important factors when selecting a split system air conditioner is ensuring it has the correct capacity for your space. A unit that is too small may struggle to cool or heat the room efficiently, while an oversized unit may consume more energy than necessary.



When determining the right size, consider the room’s dimensions, insulation, number of occupants, and sunlight exposure. Rooms with large windows, high ceilings, or poor insulation may require higher capacity air conditioning. If you’re unsure, consulting a professional air conditioning installer in Wollongong can help you make the right choice.

Energy Efficiency & Running Costs


A split system air conditioner can be a long-term investment, so choosing an energy-efficient model can help reduce electricity costs. Look for units with a high Energy Star rating, as these consume less power while maintaining effective cooling and heating.


Many modern split systems come with inverter technology, which adjusts the compressor’s speed based on the temperature requirements. This means the system doesn’t have to work at full power constantly, leading to lower energy consumption and quieter operation. Opting for a model that uses an eco-friendly refrigerant can also help reduce the unit’s environmental impact.

Features to Look for in a Split System Air Conditioner


Technology has improved the functionality of split system air conditioners, offering features that enhance convenience, comfort, and air quality. Some key features to consider include:



  • Smart controls: Many modern split systems allow you to control the unit remotely using a smartphone app, making it easy to adjust temperature settings when you’re away from home.
  • Quiet operation: If the air conditioner is being installed in a bedroom or living space, choosing a model with low noise levels can improve comfort.
  • Air purification filters: Some units come with built-in air filters that remove dust, allergens, and bacteria from the air, which can be beneficial for allergy sufferers.
  • Reverse cycle functionality: This allows the system to provide both cooling and heating, making it a versatile option for year-round use.
