The first thing you need to decide when installing air conditioning in your home is whether you will do it yourself or you will let a professional install It for you.  Some air conditioner warranties get invalid if it was self installed so it is good to check on the warranty that can with the unit.  In many places, the only person allowed to install  the refrigerant in the air conditioner is a licensed air conditioner professional known as an AC contractor.


The installation of an air conditioned should not be given to just any handyman.  Installing an air conditioner requires a lot of work and it is important to have some acquired skills to work with ductwork, carpentry, copper piper and plumbing.  There are some things that you need to know before purchasing your air conditioner and these are the total area of your home that is to be cooled, the place where you are going to put both parts of your air conditioner, and the size of the unit you will need in order to cool the area that you want cooled.  An online air condition capacity calculator will help you determine what is needed for your specific AC installation.


You will need tools including a vacuum pump, hose set, pipe cutter, and a refrigerant manifold gauge.  IT is also important to have a solid stable pad on which you will position the outside unit.  Concrete, weather-resistant wood or any other composite material that will be suitable for longer term outdoor use are the materials that this pad can be made of.  The outside unit of your air conditioner should be placed away from the exterior wall of your home so that vibration will not be transmitted into your home, and so that you can have easy access for maintenance.

A central location for the air conditioning unit that comes inside should also be selected.  This is the best location that will allow for air distribution throughout your home.  With this, you will have access to the external wall where the drainage pipe, electrical wiring, and copper pies to the outside unit are installed.  Make sure to pay close attention to where the drainage pipe is installed because it needs to drain where the water will not pool.  Before the pipe can be installed or cut, you need to learn how to bend and flare copper pipes, if you have little or no experience at all.



AC installation from requires experience and many different tools that a homeowner handy man would not generally have in his toolbox or have experience with.  Installing your air conditioning system is best done by a professional AC contractor.
