How Does Ductless Mini-Split Installation Work?
The installation of a ductless mini-split system involves several steps, starting with choosing an appropriate location for both indoor and outdoor units. This includes considering factors such as ease of access, aesthetics, and the desired distribution of heated or cooled air. Once the locations are determined, the next step typically involves mounting the indoor units on the wall or ceiling and the outdoor unit on a solid base or bracket.
After securing the units, the refrigerant lines and electrical wiring are connected between the indoor and outdoor components. This configuration usually requires drilling a small hole in the wall to install the refrigerant and electrical lines securely. Finally, once all connections are made, the system is charged with refrigerant, and the units are tested for optimal performance. This combination of simplicity and effectiveness makes ductless mini-split installation a compelling option for many property owners.
