Mitsubishi Ductless Split System Benefits


A whole-home system from Mitsubishi Electric Cooling & Heating can help ensure better, fresher air in your home.

Advanced Multi-Stage Filtration

Capture and remove contaminants that trigger allergy and asthma symptoms, spread illness and impact air quality.

Platinum Deodorizing Filter

Available on select systems, Platinum Deodorizing filters use nanotechnology to absorb odors to neutralize the worst smells.

Washable Filters

Washable filters last up to 10 years and give you another way to save money and reduce environmental impact.


Mitsubishi Electric Zoned Comfort Solutions™ help you use the minimum amount of energy needed to maintain your desired indoor temperature.

Inverter-Compressor Technology

Conventional systems are either on or off. All or nothing. Our compressors ramp up or down based on the needs of each room to maintain comfort and conserve energy.

Zone-By-Zone Control

Control each zone in your home independently and even turn off zones that are not in use.

Energy Star

Many of our systems are ENERGY STAR qualified and may be eligible for federal and state tax credits or local utility rebates.


Mitsubishi Electric Cooling & Heating has introduced a significant advancement in heat pump technology, making our products an excellent solution for maintaining your home’s comfort, even in extreme cold climates.

Hyper-Heating H2I

Designed to provide comfortable indoor temperatures in extreme cold-climate conditions (as low as -13° F) while saving energy and money.

Minimal Energy Consumption

INVERTER zoning systems deliver only the amount of hot air needed to achieve the desired temperature: no more, no less.

Instant Hot-Start

Hot-Start technology ensures you feel warm air immediately.


Our indoor units operate as low as 19dB(A), quieter than a human whisper. Outdoor units operate as low as 58 dB(A)—the level of a restaurant conversation or background music.

No Ducts, No Noise

Ductless solutions and short-run ducted systems deliver cooled and heated air directly to the rooms they serve, without the need for noisy fans.

Quiet By Design

All system components are designed to work in quiet harmony with details like an insulated compressor compartment and vibration dampeners.

No Noisy On & Off

You never have to hear the disruptive clanging of a central air system turning on and off again. With our systems, that noise is a thing of the past.


Mitsubishi Electric makes it easy to stay in control of your cooling and heating systems with our new kumo cloud™ app, available on smartphones and tablets. You can access the app wherever you are and choose from a variety of options to customize your experience. With flexible temperature settings, timer functions, and energy-saving programs, this app simplifies the task of managing your home climate. Enjoy ultimate convenience and control with Mitsubishi Electric’s kumo cloud™ app.

Remote Comfort

Remotely adjust your settings so every room in your home is the perfect temperature, avoiding unexpected cold and hot surprises upon your return.

Total Zone Control

RedLINK™ technology allows you to connect up to 16 devices to your cooling and heating system, without interfering with other wireless home devices.

Program Settings

Program schedules for mode and temperature with our kumo cloud app and create reminders to check the status of filters.


Mitsubishi Electric Zoned Comfort Solutions™, including our deluxe wall-mounted models, use advanced features like 3D i-see Sensor™ to monitor occupancy in individual zones and adjust the temperature so you are always comfortable.

Zoned Monitoring

Air handlers in each room measure return air and adjust automatically, rather than adjusting to conditions measured by a thermostat in a different room.

3D I-See Sensor

For select units, 3D i-see Sensor scans the room, detecting occupants’ heat signatures, and adjusts temperature and airflow to maintain temperature and eliminate cold or hot spots.

Inverter Technology

Rather than turning on and off at certain temperature thresholds, INVERTER technology continuously ramps up or down to maintain the desired temperature.


With Mitsubishi Electric’s Zoned Comfort Solution™, you can tailor your home heating and cooling needs to the unique requirements of each room. Instead of having a single system that treats all areas equally, our systems focus on each living space individually. This results in greater customization, energy efficiency and simpler installation processes. With this advanced technology, you can achieve the precise comfort level in each room of your home that you desire. Whether you need to heat or cool a single room, renovate your entire house, or build a home from scratch, Mitsubishi Electric has the perfect solution for you.
