Poor Support and Reliability Issues

This tri-zone system is difficult to install due to thin-walled line sets that are challenging to flare. After setup, one indoor unit displayed an E0 error code and was disconnected. Heating performance is inconsistent: one unit heats briefly then shuts down, allowing the compressor to cycle, while another unit does not heat at all. Customer support is only available via email, with no phone number provided. The experience suggests caution when purchasing without direct phone support.

Cons
  • − thin-walled line sets are hard to flare
  • − one unit showed E0 error code
  • − inconsistent heating and shutdown issues
  • − no customer service phone number, only email

Good Budget Multi-Zone Mini Split

This multi-zone mini split is easy to install, even for those without prior experience. Customer service was responsive when the condenser package was misdelivered, quickly sending a replacement. The condenser arrived dented due to rough shipping, not the seller. The main drawback is an intermittent metallic noise from the indoor coils that can disturb a sleeping toddler. Overall, it is a solid budget option and worth recommending for those wanting an affordable, easy-to-install multi-zone system.

Pros
  • + easy installation
  • + responsive customer service
  • + great price
  • + good value compared to expensive brands
Cons
  • − intermittent metallic noise from indoor coils
  • − condenser arrived dented due to shipping

Quiet and effective, with some installation requirements

Installation requires a vacuum pump, and the indoor units come charged with nitrogen. A flare kit may be needed because the lines combine metric and standard fittings, though careful routing of the extra line can avoid this. Setup of the outdoor and three indoor units is otherwise straightforward. Operation is very quiet, even compared to a central unit, and it keeps an 800 sq ft house cool in Texas heat. The app is fairly easy to use, but one indoor unit will not connect to wifi. Durability and the first electric bill are still unknown, but no issues have appeared so far.

Pros
  • + very quiet operation
  • + cools an 800 sq ft house in Texas heat
  • + straightforward installation
  • + app is fairly easy to use
Cons
  • − requires a vacuum pump for installation
  • − indoor units come charged with nitrogen
  • − lines combine metric and standard fittings
  • − one indoor unit will not connect to wifi
