How Does A Ductless Mini-Split Work?

A ductless mini split is an air conditioner or heat pump that is installed with no ductwork. The indoor unit is mounted inside the home while outdoor unit looks similar to a traditional air conditioning unit. Each unit is used to heat and cool one room. Mini splits are efficient and come as an air conditioning unit or heat pump which heats and cools. Ductless air conditioner and heating systems usually have four main parts:

  • Outdoor Unit: This part houses the condensing coil, expansion valve, fan, and variable speed compressor. Because the compressor controlled by inverter technology, it’s able to bypass the common cycling of a traditional HVAC system and instead match the heating and cooling load of the room.
  • Indoor Unit: Inside the indoor unit, the evaporator converts the indoor air to warm or cool based on the position of the reversing valve. The conditioned air is then blown into the room by the oscillating fan.
  • Refrigerant Line Set: This set is made up of the condensation drain, insulated copper tubing which carries the refrigerant, and a power cable connecting the indoor and outdoor units.
  • Remote Control: Each indoor unit has a remote control which allows you to adjust, set, and program the desired temperature.

Several models will heat down to minus 20 degrees Fahrenheit in the winter. Generally, one-to-one units — one outdoor unit to one indoor unit — are most common as they’re installed in a new home addition or remodeled space. But, our technicians can also install systems that include one outdoor unit and multiple indoor units.

Types Of Ductless Indoor Units

Ductless splits generally use four types of indoor units and Hoveln Heating & Cooling, Inc. will work with you to determine the best type of unit for your home and needs.

Wall Mounted

The most common type of ductless indoor units, wall mounted units are frequently found in individual rooms. Airflow from these units is controlled by motorized vanes found on the unit bottom.

Ceiling Recessed

A ceiling recessed unit, or cassette, pushes conditioned air in four different directions at once. This type of unit is ideal for open floor plans and for areas that have at least one foot of clearance above the ceiling.

Floor Mounted

A floor mounted unit generally rests on the floor or is secured to the wall just above the floor. Known for its ease of maintenance due to location accessibility, a floor mounted unit pushes conditioned air toward the ceiling.


The most visible part of a concealed unit is the grille, generally located above a soffit. A concealed unit may provide air to different rooms or zones in the home using a small amount of ductwork.

Advantages Of Ductless Heating & Cooling

Controlled Comfort

Perhaps the leading advantage is the ability to control the temperature in an individual room. Each unit has a dedicated thermostat which allows the room, or zone, to be adjusted to your preferences. But comfort also extends to improved indoor air quality — without ductwork, allergens have less space to build up.


While window air conditioners are technically ductless, these units are less secure and can present a safety issue to the home. Most ductless systems only need a three-inch hole to be bored into a wall for installation rather than using a window.

Addition & Remodel Friendly

These systems work well in sunrooms, bonus rooms or areas of the home where it is impossible to install ductwork. Our technicians have also installed several mini-split units in server rooms for businesses. Whatever the need, count on Hoveln Heating & Cooling, Inc. to design a ductless system to exceed your expectations.

Easy Installation

Since designing and installing traditional ductwork isn’t necessary, a ductless split system can be set up in as little as one day.

Energy Efficient

Traditional ductwork can lose up to one-third of the conditioned air before it reaches the rooms in a home. Ductless heating and cooling systems, however, deliver the air directly into the room, greatly reducing the energy loss. Plus, the compressor in the outdoor unit can more precisely match the heating and cooling load year-round through modern inverter technology.
