What is a Mitsubishi Electric Ductless Mini-split?

A ductless mini-split (also known as a wall-mounted heating/air conditioning unit) is one outdoor unit, a heat pump or air conditioner, connected to one or more small air handlers located on a wall inside your home.

The indoor and outdoor unit(s) is connected with refrigerant piping and a power cable. Ductless split units operate at very high efficiencies because they use inverter technology, also known as variable speed technology, to operate the outdoor compressor.

Furthermore, this inverter technology allows the heating and cooling to be done with variable capacities. Because temperatures fluctuate so much, variable capacity heating and air conditioning conserves energy on milder days and increases indoor comfort because more dehumidification takes place.


How does a Mitsubishi Electric Ductless Mini-split unit work?

Unlike traditional forced air furnaces and central air conditioners work, Mitsubishi Electric ductless mini-split units do not use ductwork to move air throughout the home. Instead, a small attractive air handler is mounted, generally high up on a wall. This little air handler has a very quiet blower that circulates the air and transfers heat outside of the home via the refrigerant piping.

Frequently Asked Questions

How are Mitsubishi Electric ductless mini-splits controlled?

Mounted on the unit is a temperature sensor that turns the system on or off. As the air circulates through this little air handler, the air passes the temperature sensor. The temperature is set from a wireless remote that you can either mount on a wall or leave on a table.

What if I have multiple rooms that I want to condition?

For many years, ductless mini-splits were only available to connect one indoor air handler to one outdoor heat pump or air conditioner. Now, they have the ability to connect more than one indoor unit with one outdoor heat pump. Not only does this give the homeowner the ability to heat and cool multiple rooms, it reduces installation and operating costs.

How secure are Mitsubishi Electric ductless mini-splits?

Ductless split units are more secure than having window units. These do not require an open window to operate which makes them a much more secure solution for you and your family.

Is Mitsubishi Electric ductless mini-split a good option for my hot sunroom?

Yes! Too many times we see a beautiful sunroom at someone’s home that is not being enjoyed because it gets too hot in the summer and too cold in the winter. In the winter, clunky space heaters end up sitting in the middle of the room. A Mitsubishi ductless mini-split unit provides personalized comfort throughout your home year-round.
