Our Picks for the Best Dual Zone Mini Split Systems

Single Zone units heat and cool 1 room, while Dual zone units heat and cool 2 rooms.

What Is a Dual Zone Mini Split?
A Dual Zone mini split heats and cools two rooms using only one outside condenser.
 
A Dual Zone mini split has two inside wall units in separate rooms.

It has only one outside compressor to operate both inside wall units.

This can be very beneficial in many scenarios such as limited outside space or keeping cost down.

Dual zone systems use only one outside condenser while a single zone system would need two outside condensers.

Be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.
