Mini Split Installation Tips

Installing a mini split air conditioning system can be a daunting task, especially if you have never done it before. However, while some installation may require qualified electricians or experienced handymen, others can usually be installed with just some basic safety precautions and practice. Let’s take a look at some tips and techniques to help ensure a successful and hassle-free installation.


Before attempting a mini split installation, it is important to follow a few basic safety precautions. Make sure to switch off the power at the breaker box and, if possible, install a dedicated circuit. It is also advisable to look up the manual for the specific model and follow the instructions provided. It is important to prepare the necessary tools and materials before starting work. An adjustable wrench, hack saw, tube cutter, wire cutter, and screwdriver are all essential for the job.

Drain Line

The mini split installation will require a drain line or condensate pump to take away the condensation created by the system. For larger models, flexible PVC drainpipes are usually the best choice. The drain line should provide the correct slope to allow water to easily flow away from the unit. If the lines are too long or turn too sharply, they may require additional slopes to ensure proper water drainage.

Electrical Wiring

Most of the electrical wiring for a mini split installation can be done by the homeowner. It is important to understand the wiring diagram as most systems are designed to have both a hot and a neutral line. It is critical to ensure that the polarity is correct and that the wires are properly secured. All exposed wiring should be insulated and covered with electrical tape. Additionally, the connections should be secure and any unused wires should be capped off.


The mini split should be mounted properly and secure it to a secure base. The wall should be level and the distance between the indoor and outdoor unit should be accurately measured. Many mini splits are designed for mounting to a wall or ceiling, but it is important to follow the specific instructions provided to ensure a secure fit. For example, some units may require additional spacers or special screws.

Refrigerant Line

The mini split refrigerant line should be securely connected to both the indoor and outdoor units. A copper tubing between the two units should be carefully bent and securely connected. The lines should be insulated to prevent condensation build-up. Additionally, the line should be fitted with a pressure relief valve to help ensure the system remains safe.

Testing and Maintenance

Once the installation is complete, it is important to double-check the connections and test the system. The system should be activated and run for at least a few hours to ensure everything is working properly. Additionally, it is important to periodically check the unit for signs of condensation or vibrations. Regular maintenance is also essential to ensure that the system performs optimally.


Installing a mini split air conditioning system can be a challenging task, especially for those who have never done it before. However, with the right knowledge and preparation, it is possible to successfully complete the installation. Make sure to take all necessary safety precautions, and follow the instructions provided by the manufacturer.

Mini Split Installation Tips

Installing a mini-split air conditioning system can be a daunting task. However, with some proper planning and expert advice, you can ensure that the project goes off without a hitch. Here are a few tips and recommended steps to take to ensure your mini-split installation is successful.

Secure the Necessary Permits

Certain municipalities may require permits for the installation of a mini-split air conditioning system. Make sure to research the local codes and regulations to ensure all permits are in place and properly filed before work can begin.

Choose A Reliable HVAC Technician

When it comes to mini-split installation, hiring an experienced technician is of paramount importance. Look for a technician with experience in the type of mini-split system you are installing, and make sure to get references from past customers who have been satisfied with their work.

Carefully Read the Installation Manual

Most mini-split systems come with an extensive installation manual. Read the manual carefully and make sure to follow all instructions and safety recommendations. If you have any questions or concerns, consult a professional before continuing.

Gather the Necessary Tools and Materials

Make a list of all the tools and materials you will need for the installation, and make a trip to the hardware store to ensure you have everything you need. This will help ensure the installation goes as smoothly as possible.

Allow Plenty of Room for the Unit

Make sure to measure the space where the mini-split will be installed carefully. Make sure the unit has enough space around it to allow proper circulation of air, and that it is not placed in an area prone to flooding or water damage.

Create a Vented Exhaust

Mini-splits generate hot air as they cool a room. Make sure you install an exhaust vent to redirect the hot air to the outside. This will help maintain the efficiency of the unit and extend its lifespan.

Don’t Forget the Sealing

After the unit is installed, use weather stripping around edges, joints, and other areas where air may leak. This will help ensure the efficiency of the unit and prevent dust and debris from entering the unit.

Test the Unit for Quality

Once the installation is complete, run the unit to make sure it is working properly and to make sure all of the connections are secure. If any issues are noticed, contact a professional technician immediately to ensure the unit is installed correctly and safely.

In order to ensure that your mini-split installation is a success, it is important to take all of the necessary precautions and to be mindful of all of the steps involved. By following these tips and recommendations, you can be confident that your mini-split will be installed correctly and safely.
