Considering the indoor and outdoor possibilities when deciding the location of a mini split installation ensures the system functions effectively. Choosing a proper location will optimize the system’s performance.

Indoor and outdoor factors such as building structure, trees, weather, pets, pests, and environmental conditions are important to consider. Coastal areas, for example, need to meet specific codes and conditions for salt exposure requirements.

Choosing the correct location for a mini split installation is important, as it can improve its performance, increase energy efficiency, and extend its lifespan.

For the best cooling and heating performance and temperature control, install the indoor unit in the center of the room, between 7 and 8 feet high, blowing across the length of the space. This will help distribute the air evenly throughout the space with multiple rooms. Additionally, ensure no obstructions are blocking the airflow from the unit, such as furniture or curtains.

Place the outdoor heating and cooling unit in a spacious, well-ventilated area. Clearance for airflow is a manufacturer requirement, usually about 12” off the exterior wall. Using a mounting bracket or stand will usually allow the outdoor unit to be much closer than 12” due to the unit being able to pull air from underneath.

If possible, avoid placing the outdoor unit in direct sunlight or in an area that will be impacted by snow. The manufacturer’s installation manuals will provide specific details on how to protect the outdoor unit when this is not an option. Also, avoid areas where debris can accumulate.

A mounting bracket or stand will help keep grass and dirt from accumulating on the unit which negatively affects the ductless mini-split system's performance.

Make sure to place the outdoor unit on a stable surface to reduce vibrations and noise.

Be sure to seal the hole in the wall where the copper penetrates the space and to the indoor unit with a suitable material. This will prevent outside air, rodents, and insects from entering the space.

Always protect your copper piping with a line set cover. A line set cover will protect the insulation from breaking down. Exposed copper piping due to insulation degradation will add load on the entire system thereby reducing its efficiency and capacity.

While there are some ductless air conditioners sold as DIY Mini splits, it is always a good practice to hire a professional HVAC contractor to install the system correctly and efficiently.

Correct installation saves energy and creates a cozy indoor space, important for comfort and cost savings in the future. Also, working with refrigerant requires an EPA 608 certification to ensure proper handling and safety requirements are maintained.

Of course, always follow the manufacturer's instructions for proper installation, setup, and use.
