How Do They Work? 

A ductless mini split is a great alternative for a central heating and cooling system. They have many great attributes like how they run much quieter than other system types, more affordable than a central system and have versatile options for cooling multiple spaces at a time, to name a few. Still, you may be wondering how does a ductless mini split system work and how do they differ from a central system.

Indoor Unit

The key feature of the ductless mini-split is that they don’t utilize a duct system. Instead of using a duct system to move the conditioned air throughout the home a mini split system utilizes an indoor air handler. The air handler is usually horizontal in shape, slender and usually hangs from the wall closer to the ceiling. The air handler holds the washable filter, an evaporator coil with refrigerant lines, a small blower and a condensate pan and temperature sensor. You can use multiple air handlers in the home, connected to the same outdoor unit, as well which is referred to as a multi-zone system.

Outdoor Unit

The outdoor unit is very similar to a central air conditioning condenser, as far as its components. Mini-split condensers house refrigerant lines, condensing coil, compressor, and fan/blower. They can be located on the rooftop or ground level and are shaped similarly to a box fan.

Heating and Cooling

To create cooled air, the indoor unit takes in warm air from your home and sends it to the coils outside. A cooling process then takes place starting with the refrigerant at the indoor unit which then continues in the outside unit, ending in cool air being blown back into the house by the inside unit. The heating process is similar, just in reverse. Heated air is taken from outside which is then used to generate heat in the refrigerant which goes back to the inside unit and is dispersed inside the home. Due to the heating process relying on pulling in heat from outside, ductless are not always the best option for places with extreme winter climates.

Energy Efficiency

One of the features that make ductless mini-splits a good investment is that they are highly energy efficient. Ducting accounts for up to 30% of energy used in a central system. The air conditioning and heating units have to work harder to disperse air throughout a duct system and since ductless mini-splits do not utilize a duct system to disperse the conditioned air they save more on energy.

After reading how a ductless mini-split works, you can see that these types of systems have both an efficient and effective way of taking care of your heating and cooling needs. You many now see that a ductless mini-split is a smart option for your home, business or ADU.
