Many home or building owners do install part or all of their own mini split AC system, saving considerably on contractor costs. Let’s take a look at what is involved so you can decide for yourself whether or not your skills are up to the DIY challenge.
First of all, the compressor will need to be mounted to the exterior of the home or building, which will require the ability to fasten the bracket to the outside wall. The type of wall will determine whether wood screws will be sufficient of if concrete or mortar screws and the appropriate drill and bits are necessary.
The next step is to run conduit that will contain the power line, refrigerant line, and condensate drain line. This can vary in terms of difficult depending on the structure. To carry the conduit through the wall you’ll have to saw a 2.5 to 3 inch hole using a high-powered hole saw.
The individual air handlers are very easy to mount on a ceiling or high on a wall using the mounting hardware included. Use a stud finder to give you the ability to anchor the fasteners into studs. Once they are in place, run the conduit and hook up the connections.
One task advanced DIY enthusiasts go ahead with while others leave it to a professional is the electrical hookup into the box. This can be complicated, as well as dangerous. Read the included installation information before deciding whether or not to give any part or all of the installation a shot.
