Dual Zone Mini Split Reviews: Installation Cost, Best Brands

A dual zone mini split system will provide air conditioning, heat, dehumidification, and ventilation to two zones or locations in your home. These systems include an outdoor condenser and two indoor air handlers. Dual zone ductless systems are not the only type: Single zone, tri-zone, 4 zone, 5 zone, and even 8 zone systems are produced by the leading brands of mini split heat pumps.

Pro Tip: What’s better, a dual zone system or two single-zone systems? If you’re looking for dual-zone coverage, you can either purchase a two-zone system or buy single zone units for each area you need coverage. Multi-zone units are usually best installed by a professional but some of the single zone units can be installed by the homeowner. The potential value of using two separate single zone systems instead of a dual-zone system is that if one of the systems breaks down, the other will continue to provide heating and air conditioning. But if a true dual-zone system with one outdoor unit and two indoor units fails, you’ll have no heat or cooling.

This article reviews dual zone units followed by reviews for several single zone units.

Mini Split System Installation Cost

Your ductless heat pump installation costs will depend on the size of the system and how you configure your system. As we’ve noted, if you’re DIY, we recommend considering installing multiple single-zone setups rather than one multi-zone mini split system (one condenser unit outside with two or more indoor air handlers). Single-zone systems are easier to troubleshoot, and if one system goes down, the other will provide heating and cooling to its zone.

This chart shows retail costs for single zone and dual zone systems of various sizes/capacities. The cost of installation is discussed in the next section.

9,000$895 - $1,050N/A
