Mitsubishi Electric Ductless Systems

What is Duct Free?

For decades, split-zoning air-conditioning and heat pump systems have been the quiet solution for cooling and heating problems around the world. Our quiet and powerful systems have three main components: an indoor unit, outdoor unit, and remote controller. Installation is as simple as mounting the indoor and outdoor units, connecting the refrigerant lines, and making a few electrical connections.


 


 

 

Why Mitsubishi Electric Systems?

Our commitment to empower homeowners to create their own customized comfort is fueled by continual innovation and refinement. Here are some of the technologies that help cool and heat your home more efficiently and effectively:

 

Hot-start

The indoor unit’s fan only blows air when the coil has warmed to the desired temperature. An energy-saving measure, it also prevents drafts of cold air at start-up.

i-see Sensor™

This sensor scans the room and adjusts temperature and airflow automatically. Maintain consistent comfort by eliminating cold and hot spots.

H2i® Technology

Hyper-Heating INVERTER (H2i) technology is designed to provide comfortable indoor temperatures in extreme cold-climate conditions (as low as -13° F) while saving energy and money.

Zone Control

Why cool or heat rooms you don’t use? Why sweat or shiver in those you do? Zone control allows you to optimize the temperature of any space with an indoor unit to save energy and reduce costs. Create your own perfect comfort zones!

Quiet Operation

Indoor units run quiet as a whisper and outdoor units run quieter than a refrigerator. You have to hear it (or not) to believe it!

Enhanced Filtration Systems

Washable filters last up to 10 years and remove pollen, dust, dander and other allergens that reduce indoor air quality. Each room has its own filter to ensure pristine air.

Where Can Mitsubishi Electric Products Be Used?

If a room is too hot or too cold, Mitsubishi Electric Cooling & Heating can handle it! Mitsubishi split-zoning systems are specifically designed to improve the comfort level in an uncomfortably hot or cold room of an existing building. Because they don't require ductwork, they're the perfect heating and cooling systems for renovating older buildings that were constructed before air conditioning was available - even those with plaster walls and brick facades. The versatility and variety of applications for Mitsubishi Electric systems are virtually unlimited. They're an excellent choice for almost any spot cooling or heating situation, including enclosed sunrooms, upstairs bedrooms, classrooms, hospitals, nursing homes, restaurants, hotels, workout rooms, computer rooms, offices and churches.

They're also equipped with an anti-allergen filter and prevent the cross-flow of air with contaminants. And because they can be controlled by zone, it's easy to set the controls for the exact room temperature you want.

How does it work? Mitsubishi Electric Cooling & Heating can fit into almost any space because their innovative engineering optimizes the capabilities of the INVERTER technology and R410A refrigerant for more efficient systems with smaller indoor and outdoor units. R410A refrigerant is environmentally friendly, with zero Ozone Depletion Potential (ODP). The units themselves are also made of recyclable materials.
