Ductless Heating and Cooling Systems

Ductless Heating and Cooling Systems

Could your home benefit from ductless heating and cooling? Check out these pros and cons.

When it comes to home comfort, the temperature is one of the most crucial. One may take for granted that the house stays cool in summer and toasty in winter, not realizing the mechanics that go into this system. Most homes have a traditional HVAC unit that blows warm or cool air throughout the house through a series of ducts. Meanwhile, some homes benefit from geothermal heat and cooling. Others still are enjoying one of the newest inventions: ductless heating and cooling systems.

What Are Ductless HVAC Systems?

Ductless heating and cooling systems, also known as mini-splits, heat and cool individual rooms and can connect with other units to control the temperature of 2-8 rooms. Each room has a unit installed on the ceiling, in the ceiling, or on the wall at varying heights. There are different styles from which to choose; some even look like wall art. As the name implies, they require no ductwork. One can control the mini-splits remotely or with a handy, wall-mounted thermostat.

How Do They Work?

These systems, at their most basic, consist of three parts: the HVAC unit that is inside of one room, the air handling unit, and the condenser. First, the indoor unit takes air from the room. The air travels through the air handling unit, which is a pipe located within the wall connected to the condenser outside. When the hot air contacts the condenser’s coils, the condenser takes its energy to power the coolant inside the coils and thus cools the air. The air then goes back through the pipes and out from the indoor unit. If you use the system to heat multiple rooms, you will need to connect the units to a heat pump.


There are plenty of pros to ductless heating and cooling systems. Ductless units are very quiet. Most models are variable speed and hardly ever run at full speed. They also save a significant amount of energy that can get lost in traditional HVAC ductwork. They are also great solutions for home renovations and additions, especially single large room additions like sunrooms, great room/ bonus rooms, and over-the-garage rooms. You won’t have to replace yards of ductwork or install more within the walls. Ductless units keep only the room you’re using comfortable, so you aren’t wasting energy by powering the temperature of the whole house. They also have various models to choose from and have a minimal presence.


Because it is a newer system, these units are pricey. The expensive side of ductless HVAC systems can easily turn off a homeowner. However, they can have the assurance that they will save significantly in the long-run. 

The two biggest downsides to mini splits are linesets and the number of indoor units needed to condition a space. Mini splits work best in existing homes where ductwork is difficult to install. The indoor unit and outdoor unit are connected by a copper lineset, and if it’s an existing house, the lineset will be exposed on the outside of the house. That means for every indoor unit you will have a line running down the exterior. (Unless you rip out the dry wall and hide it inside the wall. Another con is the higher frequency of maintenance. These are smaller units and need more regular cleaning. Lastly, the most popular indoor units are bulky and come in limited colors, usually white. As mentioned, though, there are many styles to suit one’s aesthetic.
