💡 How to build a Mitsubishi multi-zone system: pick one outdoor unit, then add one indoor unit per room (at least two): GX wall mount, FX wall mount, MFZ floor, MLZ cassette, SLZ cassette, SEZ ducted, PEAD ducted or SVZ air handler. Each page includes its own installation.

PUMY outdoor units connect indoor units through a branch box, sold separately. Some indoor units work with MXZ only; each indoor unit page lists the outdoor units it works with. Not sure? Call us and we will put the system together for you.

🏡 Central & Hybrid Systems

Zuba-Central (all-electric)

Zuba-Central replaces a furnace and AC with one ducted cold-climate heat pump, 2 to 4 ton. Heats down to −30 °C and carries a 10-year parts and labour warranty.

Zuba-Hybrid (keep your furnace)

The PAA cased coil pairs a Mitsubishi outdoor unit with your gas furnace for a dual fuel system. The furnace takes over only on the coldest days.

🌡️ Standard or Hyper Heat?

Hyper Heat

Mitsubishi's cold-climate technology holds heating output as the temperature drops. The right choice when the heat pump is your main heat source.

Standard

Lower cost and very efficient. A good fit for cooling, shoulder seasons and supplemental heat, or a home with a backup heat source.
