AC Question: How Do Ductless Mini Split Air Conditioners Work?

Monday, July 2nd, 2012

Ductless mini split systems, or just ductless mini splits, are actually very simple devices. Despite their small size and sleek appearance, they are less complicated than many alternative systems. The elimination of centralized ductwork is to thank for this simplicity, as well as making ductless mini splits a great option for Phoenix residences without room for bulky duct systems.

Like more traditional centralized cooling systems, the noisy components of a ductless mini split system are kept outside. The wall units themselves emit little more than a hum as they disperse the conditioned air throughout your home. These wall units each contain a refrigerant coil and blower internally. Because both the refrigerant coil and blowers are found within the wall unit it is simple to control the temperature of different rooms separately. This zoning process adds to the system’s overall efficiency, allowing you to cool only those rooms in use through the use of multiple wall units.

It is the connection between these indoor and outdoor components that make the installation of ductless mini split systems so convenient. Installing a traditional forced air central cooling system can be a big project. When installing a ductless system all that is needed is a three inch hole drilled in your wall. Small copper pipes connect the components of the system, piping refrigerant between the compressor and the indoor wall units.

Like any HVAC unit, it is important to remember that ductless mini splits do have some possible drawbacks. While the lack of ductwork does make for easier installation and eliminate the need for a lot of space, it also means that a ductless mini split system does not provide ventilation. This is not a problem in most residences where operable windows allow for easy ventilation, but some commercial spaces may require an AC unit capable of ventilation.

If you are considering a ductless mini split system with heating in mind, know your climate. Some models come equipped to heat with an electric source, but there are also heat pump type ductless systems that work much like an air-source heat pump. These can be supplemented electrically, but if you live in an area where extremely cold weather is common you may want to consider a different HVAC system.

As is the case with any investment, you want to be sure that you are getting a product that will work for your specific needs. Ductless mini splits are not right for everyone.
