The evaporator coil has been referred to that part of the air conditioning system of yours that in reality is responsible for the cooling of the air prior to its blowing into your blessing from God Almighty: home! How interesting that the majority of the homeowners do not and may not witness the presence of the coil since it is enshrouded by a case made of metal which is generally within the attic or the closet of the indoor type. It should be mentioned for your general information that the evaporator coil would be discovered to be shaped like the alphabet A, this shall be in the shape of a web made of the coils that are of the copper metal within the indoor unit of the air conditioning system.
We could simply talk on the role of the coil so that you may grasp the fundamental comprehension on it. It has been generally believed that the cool air is created throughout the system, wherever the heat contained within the circulating air inside the A.C is actually eliminated by the evaporator heating coils. There is the presence of the refrigerant within the coil, the fluid referred to as responsible for the transfer of heat, as the air that is present inside your house passes through the evaporator coils, this refrigerant absorbs the heat content as well as the present moisture inside the air, and the result being an air that has been dehumidified and of course cool!
Now, the question that could be asked at this juncture could relate to the fate in connection with the sucked heat! The refrigerant transports this heat towards the outdoor unit, here the dumping of the heat into the outside air takes place through the condenser coils! How brilliant! It has been mentioned that this cycle when repeated would go on till the set temperature has been reached, when the cycle shall halt. During the normal operation the refrigerant remains within the copper coils, but owing to the phenomenon of wear as well as tear there appear leaks in connection with the coils, and when this takes place the AC would not be able to perform the cooling of your home as efficiently as it is supposed to carry out!
The indications in conjunction with the leakage could comprise the bills which are higher than the normal, there shall be the presence of ice with regard to the lines pertaining to the refrigerant, the custom coils online relating to the evaporator shall be frozen and on top of cool the A.C would be struggling to carry out the cooling process in addition to the hissing sounds in relation to the refrigerant lines!
