It is possible to install a central AC unit yourself, but it is not recommended. The process is difficult and can be dangerous if not done properly. It is best to hire a professional to do the job for you.

You could do it, but it would be much easier if you had a professional do it for you. Installing a central AC unit is not a difficult job, but it can be tricky if you don't know what you're doing. There are a lot of small parts and pieces that have to be put together properly, and if something isn't done correctly, the AC unit may not work properly or could even cause damage to your home. That's why it's usually best to leave the installation to a professional who knows what they're doing. They'll have the right tools and knowledge to do the job quickly and efficiently, and you won't have to worry about any potential problems down the road.
