Ductwork vs. Ductless Air Conditioning: What to Choose and When

June 7, 2019 |

Choosing a heating and cooling option for your home can seem like a daunting process. Whether it’s installing a new unit for the entire house or cooling just one room, there are a lot of things to think about. The process begins with this decision: central ductwork or ductless mini splits.

Ducted A/C’s, often referred to as ductwork, are air ducts made of sheet metal inside the walls and ceilings of your home (pictured below). Air is blown through the ducts and delivered to each room via a vent. These ducts often serve both your heating and cooling systems.

Ductless A/C’s, or ductless mini-splits, are small single units that will remove heat from each room individually. They look like small boxes that are installed on the wall or the ceiling of a room (pictured below).

The space has existing ducts.
If you already have ducts that exist, that are still in good condition, all you’ll need to do is hook them up to the new unit.

Humidity is a concern.
Ducted air conditioners do a better job than a mini-split of removing humidity from the air.

You want better air flow.
Ducted air conditioners do a good job of creating good air flow throughout your home because each room is connected to the same system.

Aesthetic concerns.
Ductless air conditioners are boxes that will attach to your wall, it is not flat against the wall or ceiling like a vent is. Some people do not like the look of a bulky box on their wall.


The cost of adding and installing ductwork is greater than an individual mini split.
Installing and adding ductwork can add up quickly, especially if it’s a large space. If cost is your main concern, a ductless system could be cheaper.

You’re adding a room to an existing space.
If you’re adding a room to your home, and your home already has ducted central air, you do not have to stick with it for your addition. It can be a lot cheaper and simpler if you just install a mini split in the add-on.

There’s no room for ducts in the walls or ceilings.
If your home has high ceilings, and you don’t to give them up to add ducts, ductless is the way to go. And in smaller spaces, like apartments, and there is no space to work with to even think about adding ducts, ductless might be your only option.

You want multiple cooling zones.
If you want each room to be a different temperature, ductless might be the way to go, because you can control the temperature of each individual room. Although, zoning can be achieved with ductwork. You can read more about that here.
