Split System vs. Ducted Air Conditioning – Which is Best?

Investing in an air conditioning system to beat Canberra’s summer heat is the best thing you can do, but which do you choose – split system air conditioning or a ducted air conditioning system?

We can agree that both are great! What will work best for your home and lifestyle is the million-dollar question (luckily, these systems don’t cost that much!), and knowing the pros and cons of each can help you make a decision.

What is a Split System Air Conditioning System?

Split system air conditioners have two main units: the head unit and a condenser. Both are mounted to a wall, but one is installed inside and the other outside. 

With a split system air conditioning unit, you can cool or heat your house. You can install a head unit in every room that needs servicing and run them separately as needed.

What is a Ducted Air Conditioning System?

Ducted air conditioning systems provide cool and warm air to your home through a duct system installed in your roof. It has a central unit with a condenser, compressor, and air handler typically installed in or on your roof.

The Advantages of a Ducted Air Conditioning System

1. Removes Humidity

A ducted air conditioning system is excellent at removing humidity. 

2. Greater Output

Ducted air conditioning units can service larger rooms than other cooling units. This unit provides an enhanced circulation of fresh air.

3. Affordable Installation

Ducted air conditioning installation in multiple rooms is much cheaper than installing several split system air conditioning systems. With a ducted air conditioning system, you only need to install one unit since you distribute the ducts to multiple areas from there.

Utilise Smart Home Technology

Air conditioning has continued to evolve over the past few years and what is exciting to see now is the utilisation of Smart Home technology! With brands such as Air Touch, Daikin, Panasonic and Mitsubishi air conditioners all offering this technology, you can switch on your system before you are home so you can truly stay comfortable in your home as soon as you step through the door.

The Disadvantages of a Ducted Air Conditioning System

1. Energy Use

Ducted air conditioning systems use more energy than split system units, and if there are leaks or damage to the ducts, their electricity use increases even more.

2. Ducted AC Maintenance

The ducts used for this air conditioning system need to regularly be maintained to prevent holes, leaks, and mould. If this isn’t properly cleaned, the air distributed throughout your home can result in allergies.
