Once you have located the dirty filter and realized that it is the source of your air conditioner problem, you are going to need to find the leak. If you find the source of the leak, which will likely be near the evaporator coils, all you have to do is turn off the AC and locate the location where the leak is. You will probably see a few small bends in the wire, which indicate that the area of the leak is close to a metal surface, usually metal flanges or the like. You can use a screwdriver or other type of tool to pry out this location, depending on the make and model of your air conditioner.
For anyone that needs a little refresher on the technology and science behind the air conditioner, I am going to give you a quick review. Basically an air conditioner is made up of a series of special tubes known as evaporator coils, a heat exchange unit (HVAC) and a photo cell. An evaporator coil is a small circuit that utilizes the concept of evaporation in order to create an extremely hot liquid, commonly known as cool air, through an evaporator chamber. The heat exchange unit or HVAC is responsible for creating the cold air that is radiated from the vents in the front of the air conditioner and uses a process called thermodynamics in order to accomplish this.
In order to fix your air conditioner problem you are going to firstly locate the origin of the dirty filter and then repair it. If you’re not familiar with the different parts of an air conditioner, you can simply look at the back of it to see where the dirty filter is located. The reason the dirty filter is at the back of your air conditioner is because it is a common place for dirt to gather, especially if you happen to be using an older model. This is also a common place for a dirty filter to get stuck and eventually clog up the system.
