Best Dual Zone Mini Split Systems (2 Heads + 1 Generator)

Often times, a single-zone mini-split system is not enough. In the case of dual zone mini-split systems, we can connect 2 indoor heads to a single generator. This usually gives us double the capacity (about 20,000 BTU) and the ability to put the 2 zone mini-split system in 2 separate rooms.

Here are a few examples where to install the 2 indoor units of the dual-zone mini-split units:

Example 1: Living Room + Bedroom

Example 2: Bedroom + Kitchen

Example 3: Kids Room + Bedroom

The dual-zone ductless mini-split units are especially popular. If you buy an outdoor generator, connecting a single head to it would be kind of a waste of the generator. Of course, if you have a nice flat and don’t need more than 12,000 BTU of cooling/heating power, buying a 12,000 BTU mini split system makes sense.

When you have a small house, a bigger flat, or if you intend to use the mini-split as an auxiliary to the central air conditioner, you would need a bigger 20,000+ BTU device. A dual-zone mini-split is a perfect solution in such a situation.

Below you will find a table with the best 2 zone mini-split system. Be mindful of the specifications; high SEER and HSPF rating are the essential characteristics of energy-efficient heat pumps.

Based on these specs, as well as reputation, price, and available reviews, we can determine with are the top dual mini splits:

Dual Zone Mini Split System Reviews (Quick Commentary)

Based on the specs, the Senville SENA-18MO-209 is the best dual zone mini split. With the SEER rating of 22.5, it beats all the competition. It also has a 10+ HSPF rating. For two 9K heads, the price of this dual mini-split is very affordable, especially because Senville is not as a reputable brand as Mitsubishi.

MRCOOL’s DIY dual-zone is all the rage lately. Everybody wants to:

  • Avoid $3,000 installation cost.
  • Still has a great dual mini-split with solid specs.

Both of these things are fulfilled in the MRCOOL DIY Dual Zone mini-split system. With a 22 SEER rating, this is one of the most energy-efficient dual mini split air conditioner.

Of course, it’s impossible to leave out Mitsubishi. They have the best reputation and don’t charge premium prices (like Fujitsu, for example). They have a variety of indoor units: you can build your own Mitsubishi dual zone mini split by picking any 2 indoor units that are connected to the outside generator.

COOPER AND HUNTER is a newer brand but they have managed to create a 21.3 SEER 2 head mini-split system for a fairly affordable price.

For everybody who needs a 2 zone unit for smaller spaces (350 sq. ft. or smaller), the Daikin 2MXS18NMVJU / 2-CTXS07LVJU is the perfect solution. It has two 7,000 BTU heads with an unbeatable 12.5 HSPF rating.
