About the SUZ-AAHZ | MLZ-KX

The SUZ-AAHZ | MLZ-KX is a Mitsubishi Electric M-Series single-zone hyper-heat pump mini-split system paired with a 1-way ceiling cassette indoor unit. Available in capacities from 9,000 to 18,000 BTU with Hyper-Heat cold-climate heating performance, it uses R-454B refrigerant and reaches up to 17.2 SEER2. Core Comfort HVAC installs the SUZ-AAHZ | MLZ-KX throughout the Phoenix metro area for garages, casitas, bedrooms, home additions, and light commercial spaces.

As a single-zone system, the SUZ-AAHZ | MLZ-KX pairs one outdoor condenser with one 1-way ceiling cassette indoor unit to condition a single room or space. We review your room size, insulation, sun exposure, and ceiling height to confirm the right capacity, then plan placement, line routing, drainage, and the electrical connection.

Sizing and placement

A 9,000 BTU unit suits a small room or one-car garage, while the 18,000 BTU configuration handles larger garages, workshops, and open living areas. We review your room's square footage, insulation, window exposure, and ceiling height, then recommend the capacity that keeps the space comfortable without short-cycling. The ceiling cassette recesses into the ceiling for 360° airflow across open rooms.
