How Does Ductless A/C Work?

You already know how central air conditioning works—an outdoor unit pumps air through your entire home. Ductless (or mini-split) systems work similarly but with one major difference: they don’t require ductwork. Instead, these individual units are installed directly in any room of your choosing.

Say you want your bedroom to stay cooler than the rest of the house. By installing a ductless mini-split, you can control the temperature for only the bedroom without wasting energy cooling down your entire home. You can connect up to eight of these systems together, helping you create perfect comfort everywhere.

Ductless vs Central Air Conditioning — What’s the Difference?

How They Work

As individual units, ductless systems generate hot or cold air on the spot for immediate temperature control. They don’t use ducts to heat or cool your home like central air conditioners or furnaces do, making them ideal for any home.


What your cooling system costs will depend on whether or not your home already has ductwork. If it does, a central A/C will be cheaper to install than several ductless units throughout the house. Likewise, if your home has no vents, it will cost you less to put in a ductless mini-split system than to add a central cooling unit and the ductwork that goes with it.

Energy Efficiency

With multiple ductless systems, you can control your home temperatures from room to room. This allows you to cool off only the spaces you use most often—and send less air to other areas. That can help you save money on energy when compared to a central A/C, which sends air to your whole house all at once.


Central air conditioners are installed outside, meaning you won’t see them when they run. Ductless systems must be installed inside, where they hang on the walls in whatever room you put them in. So if constantly seeing your A/C units will bother you, it may be better to go with a central air system.

Noise Level

That said, ductless air systems are much quieter than more traditional cooling units. So while you’ll notice a mini-split more often, it won’t interrupt your daily home life.
