How to Fix the Most Common AC Refrigerant Leaks


Leaks of the refrigerant used in air conditioning services are a typical issue that can result in less effective cooling and greater energy costs. In order to stop further system damage and save money on repairs, it’s critical to find and stop these leaks as soon as possible. In this article, we’ll talk about some of the most typical AC refrigerant leaks and how to stop them.

A leaking Schrader valve

In air conditioning repairs, refrigerant leaks frequently occur at the Schrader valve. It can leak as a result of wear and tear or poor installation, and it is found at the service ports. A Schrader valve core removal tool can be used to remove the valve core from a leaking Schrader valve in order to seal it. Then, swap it out for a new one, making sure to fully tighten it.

Leaking O-rings

The AC system uses O-rings to seal connections between its various parts. These O-rings may deteriorate or come free over time, causing leaks in the refrigerant system. Finding the precise O-ring that is causing the leak is necessary and once found, you can use an O-ring lubricant to make sure a good seal is made. If the O-ring is broken, a new one needs to be installed.

Leaky Evaporator Coil

Evaporator coils are essential parts of the air conditioning system, and leaks in these coils can cause refrigerant loss. Since they require specialized assistance, sealing these leaks might be more difficult. Coil leaks can be found and fixed with the help of sophisticated equipment and a licensed HVAC professional. Depending on how bad the leak is, then, the technician could have to replace the coil as a whole or fix the damaged portion.

Leaking Service Valves

Service valves are used to regulate the refrigerant flow in an air conditioning system. Due to wear, corrosion, or poor installation, these valves may eventually produce leaks. You might have to completely replace the valve or tighten the valve cover in order to stop a leaking service valve. It is advised that a qualified HVAC specialist complete this task to guarantee good sealing and prevent any system harm.

Leaking Refrigerant Line

Refrigerant lines transport refrigerant between the various AC system components. Corrosion, physical harm, or faulty installation can all cause these lines to leak. A qualified HVAC expert should be hired to seal leaky refrigerant lines because it might be a challenging job which may require replacing a part of the line, they can utilize specialist equipment and methods.


It is important to treat AC refrigerant leaks right away in order to maintain the system’s effectiveness and performance. While some leaks can be repaired using simple equipment and do-it-yourself methods, it is crucial to get experts like Elite Plumbing, Heating & Air Conditioning for help if the leak is complicated or if you are unclear of what to do. for more information click hear
