How to Install Mini Split on Interior Wall: A Comprehensive Guide

Installing a mini split system on an interior wall can be a great way to add efficient and effective cooling and heating to your home. Mini split systems are a popular choice for their versatility, ease of installation, and energy-saving capabilities. However, it is important to follow the correct installation procedures to ensure the system operates smoothly and safely. In this article, we will provide a step-by-step guide on how to install a mini split on an interior wall.

Step 1: Choose the Right Location

The first step in installing a mini split on an interior wall is to choose the right location. The outdoor unit should be placed on a flat, level surface with good drainage. The indoor unit should be mounted on an interior wall that is structurally sound and has enough space to accommodate the unit and its components. Consider the room’s layout and ensure that the indoor unit will not obstruct doors or windows.

Step 2: Determine the Wall Opening

Next, determine the size of the wall opening needed for the outdoor unit’s exhaust and intake. This will depend on the specific model of your mini split system. Use a drill bit that matches the size of the wall sleeve to create the opening. It is important to ensure that the opening is level and square to prevent any potential issues with the unit’s performance.

Step 3: Install the Wall Sleeve

Install the wall sleeve in the opening you just created. The wall sleeve is a metal or plastic tube that provides a secure and weatherproof connection between the indoor and outdoor units. Make sure the sleeve is properly aligned and securely attached to the wall.

Step 4: Mount the Indoor Unit

Attach the indoor unit to the wall using the provided mounting brackets. Ensure that the unit is level and securely fastened. The indoor unit should be positioned at a height that allows for easy access to the air vents and controls.

Step 5: Connect the Indoor and Outdoor Units

Using the provided wiring and refrigerant lines, connect the indoor and outdoor units. Follow the manufacturer’s instructions carefully to ensure proper connections. It is important to use the correct type of refrigerant and to maintain the correct refrigerant charge for optimal performance.

Step 6: Install the Ductwork (if applicable)

If your mini split system requires ductwork for air distribution, install the ducts according to the manufacturer’s instructions. Ensure that the ducts are properly sealed to prevent any air leaks.

Step 7: Test the System

Once all components are installed and connected, turn on the mini split system and test its operation. Check for any leaks, unusual noises, or performance issues. Adjust the settings as needed to ensure the system is working correctly.

Step 8: Complete the Installation

Finally, complete the installation by covering any exposed wiring, sealing the wall opening, and removing any temporary supports. Clean up any debris and ensure that the area is safe and ready for use.

By following these steps, you can successfully install a mini split on an interior wall. Remember to consult the manufacturer’s installation manual for specific instructions and safety precautions. With proper installation, your mini split system will provide years of reliable comfort and energy savings.
