Best 5 Zone Mini Split Systems In 2021 (Mitsubishi, Carrier, etc.)

5 zone mini-split heat pump system perfect for standard and larger houses. Basically, they are comprised of:

  • 1 outdoor unit (very powerful; around 3,000 W).
  • 5 indoor units or ‘heads’.

You can place these 5 heads in 5 different rooms to get superb air conditioning and heating capability. Five zone mini-split indoor units have 6,000 BTU to 18,000 BTU capacity (you will notice that the best Mitsubishi 5 zone mini-split offers even 24,000 BTU unit).

The small 6,000 BTU unit can properly cool a 300 sq. ft. room. The bigger 18,000 BTU units will condition the air in 900 sq. ft. room. All in all, a 5 zone mini split unit can deliver well over 40,000 BTU of heating/cooling capacity.

Where to install the 5 heads? Here’s an example:

Example: Bedroom + Kids Room + Kitchen + Living Room + Bathroom

Review Of The Best  5 Zone Ductless Mini Split System

Most of the homeowners will be able to use the upper comparison table and understand why, for example, Mitsubishi 5 mini-split system is the best. However, some commentary is definitely needed as well.

Mitsubishi is the most reputable brand when it comes to multi-zone mini-split systems without ducts. The ‘1. Mitsubishi Design Your Own 5 Zones’ unit is the best because you can cherry-pick all 5 indoor heads yourself. You can look at how big your bedroom is, for example, and pick the capacity you need there. 

Carrier and COOPER AND HUNTER both created 5 zone mini split units with SEER rating over 20. In the summer, having a high SEER rating is of utmost importance. High SEER equates to high energy-efficiency, lower electricity bills, and less impact on the environment. 

Fujitsu 5 zone mini splits always had a good reputation. The AOU45RLXFZ / 4-ASU9RLF1 / ASU18RLF model has a SEER rating of almost 20 and an HSPF rating (heating energy-efficiency) of more than 10. That, alongside Fujitsu’s good reputation, makes for an excellent five-zone ductless system.

If you’re looking for a cheap 5 zone mini split, you can always look at the Senville system. They don’t have a 100-year long tradition; this doesn’t mean they don’t have excellent specs (which they do). It just means that they can’t price their 5 zone mini split units as premium devices; the very thing you want to hear if you’re looking for a cheaper device.
