How to Fix AC Coil Leak

The AC system is made up of several sections and components, each playing a crucial role in ensuring your home stays cool and fresh.

AC coils are one of these vital components, and any malfunction of this component will result in the whole system’s failure. This is because AC coils are responsible for cooling the warm air drawn from your house before it’s recirculated to cool the house.

Generally, there are two types of coils: the evaporator coil and the condenser coil. Evaporator coils absorb the heat from your indoor air, while the condenser coils release this heat into the outdoor environment. This way, your home stays cool.

But what happens when there’s a leaking coil? Do you know how to fix an AC coil leak?

If you don’t, there’s no need to worry. Here is a guide on how to fix an air conditioner coil leak.

Top Signs of an AC Coil Leak

Before learning how to fix an AC coil leak, the first step is being able to identify there’s a problem.

If you pay attention to your HVAC system, you can easily tell when there is a problem with the AC coils and find a solution.

So, what are the most common signs of a leaking AC coil?

1. Long Cooling Cycles

When the refrigerant leaks and its levels drop, it affects the cooling process. Generally, the system will be overworking to keep your house cool.

This results in longer cooling cycles and, in most cases, higher energy bills.

2. Poor Air Quality.

A leaking AC coil can also cause poor air quality inside your home. This happens when the refrigerant starts leaking out of the coil and mixes with the air inside your home. The end result is a stuffy, uncomfortable environment.

3. Water Leaking from Your Air Conditioner

Water leaking from your Air conditioner indicates the refrigerant level is very low. Low refrigerant levels cause your HVAC unit to lose pressure, and as a result, the water starts to overflow from the drain pan.

4. Weak Airflow

A leaking coil is responsible for unresponsive airflow. In the AC system, each component relies on one another. Meaning if one fails, the whole system will, most likely, fail eventually. For instance, when the AC coil leaks, the blower motor will not perform accordingly, resulting in a weak airflow.

5. Hissing Sounds from HVAC System Unit

If you’re hearing hissing sounds from your AC system unit, it’s a good indication that you have a leaking AC coil. This sound is usually caused by the refrigerant escaping from the coil through a hole or crack.

If you notice such a sign, calling an HVAC expert should be your next move to avoid dealing with greater problems down the line.

How to Fix AC Coil Leak

If you suspect that your AC coil is leaking, the best steps to take are:

First, turn off the power to your AC unit at the breaker box.
Next, call a professional HVAC technician to come and inspect your system.
Finally, follow the technician’s instructions on how to repair the leak.

Leaks can cause all sorts of problems in an air conditioning system, so it’s important to address them as quickly as possible.

More often than not, learning how to fix a leak in an air conditioner coil involves a complete replacement of the coil. If the coil is not replaced, the leaks might keep occurring, resulting in even more costs and discomfort in your house.

But, there is one sure way to avoid the problems caused by an AC coil leak – taking preventive measures before the leaks occur.

So, which preventive measures can you take to help fix the AC coil leak problems?

Let’s find out:

Controlling Humidity Indoors

Using a house dehumidifier, you can remove excess humidity in your house and avoid AC coil leaks.

Since the coils are made of copper, excess humidity causes them to corrode and weaken, which eventually leads to cracks and holes. Eliminating humidity means that the coils will have a longer lifespan.

Use of UV Light in the Evaporator Coil

Another way to prevent an air conditioner coil leak is by using a UV light in the evaporator coil. A UV light helps to kill bacteria and mold, which can cause damage to the coil and lead to a leak.

Apply Anti-corrosive Coating on your HVAC System Unit

Applying an anti-corrosive coating on your HVAC system unit is also a great way to prevent an AC coil leak.

This will help to protect the coils from corrosion and keep them in good condition.

Regular Maintenance and Cleaning

Regular maintenance and cleaning of your AC unit is also an excellent way of preventing coil leaks. By keeping the coils clean and free from debris, they will run more efficiently and last longer.

Make it a habit to clean your AC to remove any scattered dirt or dust. This will prevent these materials from accumulating on the coils, leading to corrosion and leaks.

You can do this by vacuuming around the coils or using compressed air to blow any dust particles out that may have built up over time.

Regularly having your HVAC system serviced is also a wise choice to prevent issues such as an AC unit coil leak.

Professional technicians will ensure your air conditioner system is clean and properly checked for any issues. You may simply call a professional technician to fix your problem while you will be chilling and playing some casino games instead of a boring repair.
