Mini-Split AC Installation Guide

Installing a mini-split air conditioner is a highly specialized task that requires expertise, skill, and knowledge to ensure it is done correctly and efficiently. The job must be done with great care and precision, so in order to assist you with successfully installing your mini-split air conditioning system, we have compiled this comprehensive guide for your reference.

Understanding the Basics

Choosing the right mini-split air conditioning system for your particular needs is an important first step. There are several different types of systems that you should consider, including central air conditioners, window units, and mini splits. Mini splits are generally more efficient, allowing you to customize their capacity, positioning, and energy savings. Make sure to consult with a professional before making your decision, as there are important differences between the various types of air conditioners.


Once you have chosen a model, you need to make sure that you have everything you will need to complete the installation. This includes a professional-grade toolkit that includes a drill, screwdriver, level, and appropriate fasteners. Additionally, you will need a 3-inch hole saw, drill bit, and sealant tape, as well as a condensate drain line.


The mini split installation process is fairly straightforward, though you should always consult a professional before attempting any type of installation. Your first step is to locate the interior and exterior units; they should be placed in locations that are free from noise and other disruptions. Make sure each unit is level and, if need be, using shims to make adjustments.

Once you have determined the most appropriate locations for each unit, you can begin the process of mounting the exterior unit to the wall. Make sure to use professional-grade fasteners and fasten them securely to the wall. Once the exterior unit is mounted, it is time to make the connections.

Using the pre-drilled holes, run the electrical wiring between the interior and exterior units. If you need to run new lines, make sure to do so in accordance with local codes and electrician protocols. Make sure to securely seal any wiring connections, and be sure to also take into account any ventilation requirements as specified by the manufacturer.


In addition to electrical wiring, you must also establish the refrigerant lines between the interior and exterior units. This will involve connecting the lines to the appropriate connections, and then running the line between the two units. The line should be sealed along its length with professional-grade tape so as to ensure a tight and secure connection.

The last step in the mini-split installation process is to run the condensate drain line, which will collect and carry away any condensation that accumulates. This is typically routed to an exterior drain or the sewer line and should be secured along its length with appropriate fasteners.

Finishing Touches

After the drain line is connected and sealed, you can finish the installation by turning on the power and testing the system before you use it. Once all connections have been properly secured and tested, you can close the interior wall access panel and turn on the mini-split air conditioner.


Installing a mini-split air conditioning system is a complex and intricate job that requires expertise and precision. This guide provides an overview of the installation process, from understanding the basics to making connections and performing the finishing touches. Make sure you consult with a professional if you have any questions or concerns about the installation process.
