The filter in your air conditioning system needs to be replaced regularly to ensure that the system doesn't become clogged up with debris and dirt. A dirty AC system will work less efficiently and then stop working altogether if the filter isn't changed once per month.
A filter change can easily be carried out by a layman, and the instructions will be in your AC system manual. The AC coil is another part of the system also needs regular cleaning, but this should only be carried out by a professional.
There may be an indoor and an outdoor coil, but the main focus of this article will be the outside or condenser coil. If you want to know more about the air conditioning system, you can also navigate this source: Emergency Air Conditioning Repair & Brazing Mechanical Corporation.

Your AC works thanks to the movement of refrigerant through your system. The refrigerant travels from inside where it picks up the heat to the outside where the heat is deposited in a cyclical motion.
There are two coils, the indoor coil causes the refrigerant to evaporate and thus absorb heat, and the outdoor coil causes the refrigerant to condense releasing the heat. The AC works not by cooling the air, but by removing the heat and a dirty condenser coil can cause a number of problems.
If the condenser coil is dirty the heat cannot effectively be released from your AC system. The heat has to go somewhere, and as a result, a number of problems could occur, such as:
A Lack of Cooling: If the AC cannot exchange the heat away from your home no cooling can occur.
Frozen Coils: The indoor evaporator coil can become frozen, this is a sure sign that the system is being overworked and it's a matter of time before other components break.
