Not many people know so much about air conditioners and their different parts. However, there seems to be too much information about AC functionality, the evaporator, and condenser coil operation, and why they leak remains a mystery to many.

In Conroe, many do not know what to do when their AC coil leaks, and not many technicians offer 24/7 AC repair. This article will discuss all you should know about your AC coil and what to do when they leak.

This article is presented by our company, 24/7 AC Repair Conroe, who are the experts in the field you need.

What Are the Evaporator and Condenser Coils?

The evaporator and condenser coils work in synergy to cool your room; they cannot work in isolation; they are two complementary parts of the AC. Firstly, what is the evaporator coil?

The evaporator coil is a part of the air conditioners located inside the blower compartment or air handlers. It absorbs the heat from the air in your homes, offices and other closed compartments. The coil forms a loop with different functions that enables the air conditioner to complete the heat exchange process, resulting in refrigerated cooling as the air from the blower fan moves over the coil. One simple way to describe the evaporator coil is by saying it is the part of the AC system refrigerant where cold air is released.

As simple as the process above seems, one will wonder what could go wrong and lead to the leaking of your evaporator coil? You will find out later in this article; quickly, let us discuss the operations of condenser coils.

Although a bit more complex than the evaporator coils, the condenser coils are that part of your AC is usually outside the home. This square unit contains multiple components, which include the condenser tubes and fins, a fan, copper tubing, valves and switches and the compressor. The condenser coils hold the refrigerant in its liquid form. The refrigerant takes in heat from the air inside the house, and the air moves through a copper tube to the condenser unit. The warm refrigerant goes into the compressor at low pressure in the condenser unit. After that, the compressor pressures the refrigerant, which converts it into a hot, high-pressure gas. This released hot air flows into the condenser coils from the compressor, aiding the refrigerant in releasing most of the heat that was absorbed from your room. The fan covers the outdoor unit and blows air over the condenser coil so that the refrigerant inside it loses heat. The many coils of the condenser are to elongate the amount of time the refrigerant is in the path of blowing air, allowing it so much time to release the heat that was expelled from your room.

Causes for the AC Coil to Leak

Now that we are discussing the complexity of the AC coils let us closely look at why they leak. In an AC, the evaporator coil is the most common leak that affects it, and this is due to the AC vibration causing the aluminum fins to rub a hole in the tubing over time. More often, this is experienced in older air conditioning units. The leak that results from the old AC unit would require a complete replacement that should be done by a technician only. In the case of newer AC, especially those using R-410A refrigerant gas, the leak is a problem of the manufacturer’s coils called “formicary corrosion”, which produces residual organic compound, water, and oxygen. The combination of these elements causes pinholes if the coil is not aluminium or uncoated copper. In Conroe, credible AC professionals would assist you in replacing your leaking AC coil.

How Do You Know Your AC Coil Is Leaking?

Well, this seems very obvious, when your AC units leak, there would be a significant reduction in the amount of cooling liquid you then experience by having a hot room rather than a cool one as expected. When you notice a hissing noise, you now have to pay more for electric bills. Check for water leaks in your AC unit. You should contact AC repair experts in Conroe to ascertain your AC unit leaks and seek their intervention.

Should You Add Refrigerant Gas to Your AC Unit?

Although many assume it is okay to add refrigerant gas to their AC, many end up adding refrigerant gas, often leading to an AC leak. Only your technician can ascertain the amount of gas your AC unit needs. If you are concerned that your AC gas may be lower than it should be, contact the AC Repair technician provided by 24/7 AC Repair Conroe, TX.

When Should You Call for Technician Help

Many people wrongly believe that their AC problems would go away on their own; more terrible, the DIY type tries to tackle what they think is the problem. Avoid any of the mentioned mistakes. AC faults do not just fly away; you cannot replace an expert in fixing whatever the issue may be. You must seek technician help to look into what may be wrong and fix the issue at a very early stage. Reach out to a 24/7 AC repair technician in Conroe. Always seek expert help for your AC.

What Is the Process of Replacing Your AC Coil in Conroe?

You will require a technician to help you fix the oil leak or replace the evaporator coil leak. The process mostly involves the technician dismantling the air conditioner, removing the leaking coil, and welding a new coil. The technician would add or replace a direr/filter to absorb contaminants and moister. You must contact a technician because the new coil would be soldered under slight nitrogen pressure, and the system must be evacuated about three times. The gas is also replaced with factory dehydrated refrigerant gas.

Cost of Replacing Your AC Coil in Conroe

Determining the cost to replace your coil in Conroe varies; however one important thing to consider is if the new cooling unit has a warranty. This significantly reduces the cost of replacing the cooling unit. If your AC unit is no longer covered by warranty, you should contact an expert in Conroe, Texas for a quotation.
