Before analyzing the real causes of a refrigerant leak and how we can solve and prevent the problem, it is important to understand how a refrigerant functions. What is a Refrigerant and how does it function in the cooling process of the AC? Does a leak in the system cause a shift in the cooling process?
During the process of air cooling, this chemical changes from a liquid to a gas state that releases heat. This initially moves from the condenser coil where it is incorporated with a high temperature gas that results to condensation. This gas formation of the refrigerant then goes through an expansion device that changes the gas into liquid state. This process inside happens in vice versa without depleting the volume of refrigerant.
By no means does the “charge” of the refrigerant change not unless a leak from the system where it passes through is formed. This needs to be repaired right away or else it will continue to seep through the cracks and damage the compressor. This will also eventually endanger the cooling power losing the AC’s cooling power. Understanding how the process works will help people understand the importance of regular maintenance by both the end-user and professional AC technicians. This will not only assure daily operation but also help reduce the risk of damaging the cooling system.
Checking for Signs of a Refrigerant Leak
Frozen coils
The process that goes through with the refrigerant should be inspected as this is greatly affected when the refrigerant isn’t performing its function. The AC should have a certain charge of refrigerant that is being constantly circulated through the evaporator coils. In the event that this solution is insufficient, the coil will inadequately able to absorb heat. As a result, there will be formation of ice around the coils. This could eventually result into a breakage of the AC unit if not properly attended to.
Decrease cooling power The refrigerant is an integral part of the cooling process which is why a decrease in its functionality would greatly affect the cool air output. The very function of the refrigerant is to absorb the heat distributed in the area and is being released in the external environment. A clear manifestation of leak is a decrease in the cooling power of the AC unit. This can be evaluated in the ability of the unit to cool at a certain time and the amount of cool air that is felt from the event and in the entire room.
Hissing noise Another sign that there is indeed a leak from the refrigerant is the sound that your cooling unit is manifesting during its operation. One of the noises formed by a leak from the coils of the refrigerant is the leak found inside. The louder the sound is the bigger the leak is formed. Although this is still not considered to be a definite cause but is largely one of the reasons noise is made.
Solutions to a Refrigerant Leak
Seal the cracks and holes
The very source of the problem of depleting refrigerant inside the AC is the holes and cracks formed inside. And the very first course of action would be sealing these cracks to avoid refrigerant leaking. Technology has come a very long way and fixing a refrigerant leak has become less time consuming and inexpensive. This method is to be done by technicians as they are more knowledgeable in dealing with the AC parts. They do several leak detections like using bubble solutions, halide torches, and electronic detectors. A simpler way to address leaks is by using a repair kit: hose, valve and sealant. This can be used by clipping the hose and placing it into the suction and running the AC unit. Having your refrigerant fixed can also get your aircon gas top up for a better cooling unit.
Replacing the coils
There are several factors that is causing the leaking of refrigerant. One of the reasons why holes develop in air cooling system is its constant operation or it is already too old to operate like it used to. The equipment is constantly exposed to several debris and contaminants that may have not been cleaned for a very long time. Let a professional do it for you. The technician evaluates the state of the system if the coils have been affected and if it needs to be changed entirely. This may be a very expensive way to solve the problem of leaking refrigerants but will put the system back into its former shape.
