They are a type of ductless HVAC system that consists of two main components: an indoor air-handling unit and an outdoor condenser/compressor unit.
The indoor unit is typically mounted on a wall or ceiling inside the room you want to cool or heat. The outdoor unit is installed outside the building, usually on a wall, a concrete pad, or on the ground. The indoor and outdoor units are connected by a conduit that contains the refrigerant lines, power cables, and condensate drain line.
When installing a mini-split system outside, there are a few considerations to keep in mind:
Location: Choose a location for the outdoor unit that is well-ventilated and free from obstructions like shrubs or debris. Adequate airflow around the unit is essential for its proper operation and efficiency.
Protection: Ensure that the outdoor unit is protected from extreme weather conditions, such as heavy rain, direct sunlight, or strong winds, as these factors can affect its performance and longevity.
Mounting: The outdoor unit should be securely mounted on a stable surface to prevent vibrations and potential damage.
Clearance: Check the manufacturer's guidelines for the required clearance space around the unit to allow for proper airflow and service access.
Drainage: Make sure there's a proper drainage system for condensate water that may be generated during operation.
Professional Installation: It is strongly recommended to have a professional HVAC technician install the mini-split system. They can ensure the correct sizing, positioning, and connections for optimal performance and safety.
Keep in mind that the installation process may vary depending on your specific mini-split system model and the local building codes and regulations. Always consult the manufacturer's guidelines and local experts to ensure a safe and efficient installation.
