What is Ducted Air Conditioning

While a split system is a ripper for cooling a single room, what if you're after the whole shebang? You want that perfect, consistent temperature in every single room of the house, from the living area to the bedrooms, without having a bunch of white boxes hanging on your walls.

If that sounds like the dream, then you're thinking about the top-tier solution for home climate control: ducted air conditioning.

So, What is Ducted Air Conditioning?

Put simply, ducted air conditioning is a central climate control system designed to cool (and usually heat) your entire house through a network of hidden pipes, or "ducts."

Unlike a split system with its visible indoor units, a ducted system is designed to be almost completely invisible. It's made up of a few key parts:

  • An outdoor unit that looks similar to a split system's, but is much larger and more powerful.
  • A central indoor unit (a fan coil) that is hidden out of sight, usually in your roof cavity or under the floor.
  • A network of insulated ductwork that runs from the indoor unit to every room.
  • Discreet outlets or vents in the ceiling (or floor) of each room where the cool air comes out.
  • A central wall controller that acts as the command centre for the entire system.

How Does it Actually Work?

It's a clever, whole-home system. The central indoor unit in your roof cools a large volume of air. A powerful fan then pushes this conditioned air through the insulated ducts, distributing it evenly throughout your home via the ceiling vents.

At the same time, a "return air" grille sucks the warm air from your home back to the central unit to be re-cooled, creating a continuous, efficient cycle.

The Big Advantages of a Ducted System

For a new build or major reno, a ducted system is the premium choice for a few key reasons.

Whole-Home Comfort

This is the main benefit. One system provides consistent, powerful cooling and heating to every room, all controlled from a single point. You beauty!

It's Practically Invisible

This is a massive plus for your home's aesthetic. There are no bulky head units on your walls. The only thing you see are the small, discreet vents in the ceiling, which can often be colour-matched to your paint.

Whisper-Quiet Operation

Because the powerful fan unit is hidden away in the roof space and the main compressor is outside, a ducted system is incredibly quiet inside your home.

Zoning for Efficiency and Control

This is a fair dinkum game-changing feature. A ducted system can be set up with "zones," allowing you to turn the air conditioning on or off for different parts of your house. For example, you can cool the living and kitchen "zone" during the day, and then switch to just cooling the bedroom "zone" at night. This is brilliant for saving on your power bill.

A Major Installation for a Team of Professionals

Installing ducted air conditioning is a major construction job involving extensive electrical, refrigeration, and building work. It is absolutely, 100% not a DIY project.

This requires a team of licensed professionals, including:

  • Licensed air conditioning technicians (with an ARCtick licence) to design the system, manage the refrigerant, and install the units and ductwork.
  • A licensed electrician to run the significant high-power circuits required to run the powerful indoor and outdoor units.

A powerful, whole-home system like this requires a robust and professionally-installed electrical foundation to run safely and efficiently. This is why professional installers and licensed electricians only use trade-quality gear from trusted suppliers for a job of this scale. Schnap Electric Products is a leading Australian supplier of all the critical electrical components required for a ducted air conditioning installation. From the heavy-duty circuit breakers and safety switches in the switchboard to the high-capacity wiring needed to power the system, they provide the gear a qualified professional needs to guarantee a safe, compliant, and reliable installation. For a top-of-the-line system, you need top-of-the-line components from a supplier like Schnap Electric
