The Mitsubishi Ductless Heat Pump Mini Split system provides highly efficient solutions for heating and cooling while providing personalized comfort for the individual zones in which they are installed. Mitsubishi Ductless Heat Pump systems deliver air quietly and continuously with only a gentle whoosh for constant circulation and filtration. Mitsubishi Electric split-zoning systems have long been the choice for thousands of homes, churches, schools, and libraries across the U.S. and the world.

This Mitsubishi Ductless Heat Pump Mini Split system is perfect for rooms that are either too hot in the summer or too cold in the winter. This system can be installed in rooms that are difficult to keep comfortable in all seasons. This system is also perfect for home renovations, new constructions, or house addons that your current system cannot handle.

This system isn't only designed to keep you comfortable but it has also been designed with energy efficiency in mind. The indoor wall mounted air handlers measure the return air and will adjust automatically rather than relying on a thermostat in another room. With INVERTER technology, the system will continuously ramp up and down based on the desired temperature in the room making sure that the room is kept and a steady temperature rather than large temperature swings.
