There are two halves to your ac system.
Half is outside and half is inside sitting above your furnace.
It works by absorbing heat at the indoor half which is carried outside thru the copper tubing and dumping it there.
If you have ever held your hand over the outdoor unit and felt the heat blowing out the top, that is the heat that use to be inside your house.
As the air is blowing out the top, it is also pulling air in around the sides.
As this occurs, dust and debris is also sucked in and can begin to clog the outdoor coil.
