Ducted vs Wall Split System Air Conditioning

Dec 14, 2020Installation

There is some confusion over what the differences are between a split air conditioning system and a ducted one. While it’s an either/or decision to be made, there are noticeable positives and negatives to each option. Here are a few of the pros and cons that are more pertinent.

Ducted Air Conditioning is More Discrete

The main ducted AC unit is typically installed in a space below the roof. From there, the fan-coil unit generates the hotter or cooler air which is pushed through installed ducting above the ceiling. There are discrete places in the walls or ceiling for an installation. These sit flat on the ceiling or a wall and are barely noticeable compared to AC units affixed to a wall.

Ducted Air Conditioning is Usually a Whole House Solution

Ducted air conditioning relies on a central unit concept. At that point, it’s worth distributing between all rooms to provide warmth, cooling, or both at various times of the year. Not installing the service to a particular room is a waste when the master system is installed in the roof space.

A ducted system will only require one outdoor unit and on-going servicing costs will be lower with only one unit to service compared with multiple wall split systems.

Split System Air Conditioning is Less Expensive

When choosing between the two, split air conditioning is less expensive compared to ducted solutions. The reason is that air conditioning units can be installed only where they’re needed the most. This reduces the potential total cost of introducing air conditioning into the home.

Multiple Split Systems Air Conditioning may require multiple external units

With a split system, there’s both an internal AC unit and an external unit. It cannot operate with just one. Therefore, homes will need to have potentially multiple unsightly metal box attached to the side of the property on the opposite wall to where an AC unit is installed. Depending on how many split system AC units are installed, it can completely change the overall aesthetic that the home has from the outside.

Split System AC Is Inferior with Large Rooms

When it comes to larger room sizes, it has been found that individual AC units don’t provide comparable cooling across the entire space. Living in a home with larger room sizes, it’s best to consider a ducted system because it is more capable of managing bigger homes. While multiple AC units can be installed in expansive rooms, it’s a noisy way to approach it.
