Whether you have already purchased your split air conditioner or you are considering one, you may want to know the installation process. Below we will take a look at the overall installation process for the split air conditioner. Proper installation is essential to effectively using the system and getting the longevity out of it that it is intended to provide. Always be sure to read the instructions that come with the individual split air conditioner you have purchased.

We do not recommend that you install a ductless mini split yourself. This type of project is one that requires you hire a professional to do the installation work. In order for most ductless mini split air conditioners to be covered under warranty, they must be installed by certified HVAC contractor.

The good news is that split air conditioner installation is not all that complicated, and will keep your contractor costs down. Here is a basic summary of the installation process, so that you can follow along with your contractor, and know what type of labor will be required.

Locate where you will place the wall mounted unit. Choose a space by keeping in mind that the outdoor component it is hooked to needs to be a in an area that does not get a lot of traffic or has minimal dust.

Once you do that you will drill a 3-inch hole that leads to outside, where the other component will come together with the piping.

Next you will secure the mounting plate on the wall that will be used for mounting the indoor component. Be sure to use the appropriate bracket for the split air conditioner you have purchased

At this point the pipes will be connected from the indoor component to the outdoor one, using the 3-inch hole that has been cut.

Secure the indoor unit to the mounting bracket you have installed on the wall.

Next you will go outdoors and match up the area you chose on the other side of the wall from where you just mounted the other component.

Be sure to follow the manufacturer’s warnings regarding the space that your split air conditioner needs on all sides. For example, it will likely need to be placed 30 cm away from the home, yet need 60 cm of space out in front of it.

Place the component on the ground, secure the pipes, and fasten all the cables and clamps. 

Be sure that the outdoor component is securely in place.

Once you have completed each of the steps necessary to install your split air conditioner you are ready to bleed the unit, insulate the piping and joints, and seal the hole. It is important that the installation process for your split air conditioner be done correctly, by a certified contractor, to ensure that it works the way it is supposed to, and so that it does not interfere with the warranty.
