A ductless air conditioner is an air conditioning system that allows homeowners to enjoy the benefits of cooled air without the high cost of duct work. They are an affordable alternative to central heating, ventilating, and air conditioning (HVAC) systems, which rely on an extensive network of ducts to move air. Ductless air conditioners are considered to be more efficient and easier to maintain than window-mounted units.

Often called a “split system,” a ductless air conditioner is made up of two parts. There is a compressor, which is placed outside of the home, and a fan, which is installed in the room that is to be cooled. The fan can be wall-mounted, concealed in a drop ceiling, or set on the floor. The two units are connected using piping or conduit. The conduit contains lines for refrigerant, condensate, and electricity to run the unit.

There are many advantages to using a ductless air conditioner instead of a traditional window-mounted unit. First, because the noisy compressor sits outside, the air conditioning system is much quieter inside the home. The fan itself is generally no louder than a regular ceiling fan, though “quiet fans” are available for homes where noise is a special concern. There is also no need to remove and re-install these units every summer, and homeowners are not subject to the security risk associated with removable window-mounted air conditioners.


Another major benefit to using a split system air conditioner is the high level of energy efficiency associated with these units. Cool air is directed to the room where it is needed instead of all over the house. There is no issue of air leaks, which are common when cooled air travels through duct systems. The entire system can be controlled by a thermostat, so that the temperature in the room is kept exactly where it is set by the homeowner.

The main benefit of a ductless air conditioner is that it allows homeowners to save on the high cost of adding ductwork, which often involves tearing down walls or ceilings. This is particularly useful in older homes that have no central duct system. Many people also rely on ductless air conditioners to cool home additions, including sun rooms or garages.

Ductless air conditioners have gained a lot of popularity because of their reduced noise and also because of the fact that they do not congest house. HVAC systems are on a downfall since the arrival of ductless systems.

Also, considering the cost of installation of ductless air conditioners, it can be said that they are here to stay.
