What is a Ductless Mini Split System?

A ductless system requires no ductwork; it’s a split system because there are separate indoor and outdoor units; and it’s mini because the units are smaller than a typical central air system. It’s also the most versatile, easy-to-install HVAC system available that delivers comfort where standard central air can’t.

When only certain rooms need heating and cooling, mini-split systems provide a smart, flexible solution. Maybe you have a sunroom that’s a little too warm, or a room addition that isn’t connected to your ductwork. A mini-split system can address comfort issues in each of these rooms, without a complicated installation.

According to energy.gov, the main advantages of mini splits are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated). Each of the zones will have its own thermostat, so you only need to condition that space when it is occupied, saving energy and money.

Since mini splits have no ducts, they avoid the loss of energy associated with ductwork of central forced air systems – as much as 30% of energy consumption, especially if the ducts are in an unconditioned space such as an attic.

Compared with other add-on systems, mini splits offer sleek designs and greater flexibility. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, hung on a wall or floor-standing. Many also offer a remote control to make it easier to turn the system on and off.

The primary disadvantage is their upfront cost. The installer must also correctly size each indoor unit and judge the best location for its installation. An oversized or incorrectly located air-handlers often result in short-cycling, which wastes energy and does not provide proper temperature or humidity control. Too large a system is also more expensive to buy and operate.
