Evaporator coils and condenser coils are the two most important parts of your air conditioner. If either of these fails, then your air conditioner will not function as it should. They are all the parts that have the job of creating cool air from hot air. The air is created by heating one element (condenser coil) and then cooling another element (coil). In order for the condenser to keep the right temperature it must be clean at all times.
It is very important to keep the ground loop clean so you do not make a ground loop between the condenser and evaporator coils. The reason for this is because the ground loop is where the coolant flows back to the system. This is a very important point to remember because if the ground loop is unbalanced the refrigerant will drain back into the coil, which will cause the fan to spin up faster and eventually kill the refrigerant. If the coolant does drain back into the coil then the system will not cool because the coils cannot circulate it as fast as the refrigerant. To prevent this from happening it is recommended that you inspect your cooling system regularly and clean the system if necessary.
Another important thing to remember is that the condenser should be cleaned at least once a month. In order to properly clean it, you must turn it off while you are working with it, to ensure you do not accidentally turn it on before you are finished. Be sure to take some spray cleaner and use it to get any dirt or grime off the condenser. After you have done this you will need to let it sit in the coolant for about 20 minutes before reentering the cooling process.
