Ductless air-conditioning systems, which are also commonly referred to as mini-split systems, offer many benefits, including their small size, increased energy efficiency, and targeted climate control. But how do they work? Below is a simple guide to help you understand the basics of this popular home cooling technique.

Components of Ductless Air Conditioning (AC) Systems

A ductless AC has two main components—an indoor and an outdoor unit. The indoor unit contains a fan, evaporator coils, and adjustable air vanes, as well as thermal sensors designed to direct cooled air to specific areas of a room. It draws in warm, humid air from your home, blows it over its evaporator coils, and releases cool, dehumidified air back into the living space.

The indoor unit sends the heat and moisture it absorbed from the room to the outdoor unit via refrigerant tubing and a drain line. The outside unit releases the heat collected from inside your home, and this cooling cycle continually repeats itself. 

Ductless Air Conditioning vs. Standard Central Air Systems

As the name implies, ductless air-conditioning systems do not depend on elaborate ductwork to spread cooled air around your home. This offers a number of advantages, including a much quieter cooling experience as air typically makes noise when traveling through the ductwork. Ductless units also provide superior temperature control as each room has its own indoor temperature control. This means that the rooms in your homes have their own thermostats and can be cooled to different temperatures according to the room’s use and occupants’ desires.

Additionally, you don’t have to worry about cool air escaping through holes and leaks that often appear in ductwork. According to the Environmental Protection Agency (EPA), leaky ducts can reduce air-conditioning efficiency by as much as 20%. Furthermore, one outdoor unit can accommodate multiple indoor units, so your entire house can be cooled by a ductless system.
