What to Do if Air Conditioner Condenser Coil Leaks

One of the most common problems people have with their AC systems is when their condenser coil starts leaking. This is part of the air conditioner in which the heat is taken out of the refrigerant and then condensed into liquid form. With all the liquid generated in this piece, sometimes there are leaks that come out of the coil. Here is what to do if you are faced with an air condenser coil leak.

Air conditioner coils are an essential part of the cooling process. They are responsible for removing heat from the air and cooling it down before it is released back into your home. However, over time, the coils can become damaged, leading to leaks. If left untreated, these leaks can cause your air conditioner to stop working altogether.

What Are The Signs of Air Conditioner Coil Leaks?

One of the first signs of a leaking coil is a decrease in cooling performance. You may notice that your air conditioner is taking longer to cool your home or that it is not cooling it down as much as it used to. Another sign is a decrease in airflow. This can be caused by a buildup of ice on the coils, which can lead to further damage if not addressed promptly. Finally, you may notice water pooling around your air conditioner, which is a clear sign that there is a leak.

Causes Of Air Conditioner Coil Leaks

There are several causes of air conditioner coil leaks. One of the most common is corrosion. Over time, the coils can become corroded, leading to small holes or cracks that allow refrigerant to escape. Another cause is physical damage. If the coils are hit or bent, they can become damaged, leading to leaks. Finally, poor maintenance can also lead to coil leaks. Failure to clean or replace air filters can cause dirt and debris to build up on the coils, which can cause them to become damaged over time.

The Importance of Addressing Air Conditioner Coil Leaks

If you suspect that your air conditioner coils are leaking, it is important to address the issue promptly. Failure to do so can lead to further damage, which can be expensive to repair. In addition, a leaking air conditioner can be dangerous. The refrigerant used in air conditioners can be harmful if ingested or inhaled, so it is important to address leaks as soon as possible.

How Much Does It Cost To Repair AC Coil Leak?

The cost of repairing air conditioner coil leaks can vary depending on the severity of the damage and the type of air conditioner you have. In general, repairing a leaking coil can cost anywhere from $200 to $1500. If the damage is severe, it may be more cost-effective to replace the entire unit. It is important to get a quote from a reputable HVAC professional before making any decisions.

Hoe To Preven Air Conditioner Coil Leaks

Preventing air conditioner coil leaks is much easier than repairing them. The first step is to schedule regular maintenance with a qualified HVAC professional. This should include cleaning or replacing air filters, checking refrigerant levels, and inspecting the coils for signs of damage. In addition, it is important to keep the area around your air conditioner clean and free of debris. Finally, consider investing in a protective coating for your coils. This can help to prevent corrosion and other types of damage.
