Installing a ductless mini-split system is a detailed process, requiring the right tools and proper instructions. Before you install this system, you must decide what kind of ductless mini-split unit you want. A multi-zone system is designed with one condenser and multiple air-handlers whereas a dual zone system has one condenser and two air-handlers.

Once you decide which one you want, you will have to install the indoor wall unit. You will have to make sure the wall leads to a space outdoors as the refrigerant lines will be connected to the outdoor unit. You will also need to create a hole in the wall (preferably 2 to 3 inches) to install your indoor unit. After this you will need to decide the location of the outdoor unit and install it there.

This is by no means a detailed guide, because we believe it is best to consult a professional before you install anything. Like many heavier appliances, mini-split air conditioners and heat pumps are difficult to install. In fact, for those with little experience, they can be dangerous. Manufacturers have different instructions on how you can install these heating and cooling systems so it’s important to pay attention to details and guidelines. If you’re not sure how you can install this on your own, be sure to contact a local HVAC technician you trust so you can get the assistance you need.
