Full Product Line
Mitsubishi Systems We Install
From a single-room mini-split to a whole-building VRF system, we're trained and equipped to handle every product in the Mitsubishi Electric lineup.
Wall-Mounted Mini-Split
The most popular ductless option — mounted high or low on an exterior wall for targeted room comfort. Whisper-quiet, energy-efficient, and available in a range of capacities.
Ceiling Cassette
Installed flush between standard ceiling joists for 360° airflow distribution. Ideal for open-plan spaces, offices, and rooms where wall space is limited.
Ducted Central Air
Whole-home comfort through existing or new ductwork. Combines the efficiency of a heat pump with the familiar feel of central air — no visible indoor units.
VRF / CITY MULTI® Commercial
Variable Refrigerant Flow systems for multi-zone commercial buildings. One outdoor unit serves dozens of indoor units with independent zone control and exceptional efficiency.
Multi-Zone Whole-Home
One outdoor unit connects up to eight ductless or ducted indoor units — each zone independently controlled. Perfect for whole-home comfort without ductwork.
kumo cloud® Smart Controls
Wi-Fi control for every zone from your smartphone. Schedule, monitor energy use, and integrate with smart home platforms — all from the kumo cloud app.
