Tri-Zoned mini split systems are ideal when heating and cooling three or more rooms is needed.
Single Zone units heat and cool 1 room, while tri-zone units heat and cool 3 rooms.
What Is a Tri-Zone Mini Split?
A Tri-Zone mini split heats and cools three rooms using only one outside condenser.
A single zoned system would have 1, while a dual zoned system will have 2 copper line-sets.
Each inside unit works separately from each other with its own remote control and temperature settings.
While the inside units work individually they all use the same outside condenser to heat or cool a space.
This has many benefits in many scenarios such as limited outside space or simply wanting less outside condensers.
There are many Tri-Zoned systems available with some of our favorite picks below.
Be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.

Gree builds this 3 zoned system that can out out a total of 30,000 BTU’s.
