If you live in a home without a ducting system, someone may have recommended a mini-split system for heating or cooling to you. The truth is, these systems are an excellent option for those without preexisting ducts but not everyone is aware of how they work. Once the process is explained, you’ll understand why mini-split systems are so often recommended.
Mini-split systems still require units indoors and outdoors, but you can have up to four indoor units hooked up to one outdoor unit. Installation often only requires a hole a few inches wide in the wall. A conduit containing the tubing, power cable, and condensate drain connects the indoor and outdoor units. Essentially, these units work the same as central air conditioning but without the ducts. Each indoor unit delivers conditioned air directly, while the central air units deliver conditioned air to different areas through a network of ducts. Ductless systems also come with remote controls so you can maintain the different temperatures easily.
Why are they called mini-split?
The “split” comes from the setup described above, where the area is split into different cooling zones by hooking up multiple indoor units to one outdoor units. Mini-split systems are also called ductless HVAC, but that name is more self explanatory.
Once properly installed, mini-split systems provide zone cooling or heating. Each wall unit has its own thermostat, so you don’t have to waste energy cooling a room that isn’t in use. Overall, mini-split systems are more energy efficient than central air conditioning because they eliminate the energy losses through ductwork. They’re also great options for garages or additions where ductwork isn’t an option.
