Single-Zone is a great fit.

Multi-Zone is the better choice.

Avoid Common Mistakes

Don't expect one indoor unit to cool several closed rooms.

Each unit is designed for one specific space.

Don't oversize one unit hoping it will cool the whole house.

It won't work efficiently and won't dehumidify well.

Don't choose multi-zone if you only need one room.

You'll pay more upfront than necessary.

Don't forget each indoor unit needs a clear wall location and power.

Plan placement before you buy.
