Ducted Air Conditioning VS Split System: Which is More Expensive?

When it comes to cooling and heating your home, the type of air conditioner you choose can significantly impact your comfort and energy bills. Two popular options in the market in 2024 are ducted air conditioning systems and electric split system air conditioners.

While both have their advantages, many homeowners are often concerned about the cost implications. In this blog, we’ll delve into the cost considerations of ducted air conditioning VS split systems to help you make an informed decision based on your needs and budget.

Understanding the Basics

Before we jump into the cost analysis, let’s briefly understand how each system works

Ducted Air Conditioning

A ducted system involves a central unit that connects to ducts running throughout your home.
It provides centralized cooling and heating, allowing you no control over the temperature in different rooms or zones. One set temperature is felt throughout the house.
Ducted systems are discreet, with only vents visible in each room.

Electric Split System

A split system consists of two main components: an indoor unit (evaporator) and an outdoor unit (condenser).
It is designed to cool or heat a single room or a specific area, making it a good choice for smaller spaces.
Installation is typically easier and cheaper, with minimal ductwork required.

Cost Factors: Ducted Air Conditioning VS Split System

Now, let’s break down the cost factors associated with both ducted and electric split system air conditioners:

Installation Costs

Ducted Systems: Installation of ducted systems is generally more complex and involves running ducts throughout the entire house. This complexity can lead to higher installation costs.

Estimated cost installation cost of ducted aircon – $12000 to $16000

Split Systems: Installation for split systems is often simpler and more affordable, especially for single-room setups.

Estimated cost installation cost of electric split system aircon – $4000 to $7000 (before rebate, subsidies up to $4400 available with Cyanergy.
