​Where Can Mitsubishi Electric Products Be Used?

If a room is too hot or too cold, Mitsubishi Electric Cooling & Heating products can handle it! Mitsubishi Electric split-zoning systems are specifically designed to improve the comfort level in an uncomfortably hot or cold room of an existing building. Because they do not require ductwork, they are 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 are 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.

What is Mitsubishi Electric Cooling & Heating?

For decades, split-zone air conditioning and heat pump systems have been the quiet solution for Cooling & 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.
