A potential leak of AC freon is something that a lot of homeowners are worry about, especially because the signs of this occurrence can go unnoticed until the unit has ceased operating and cold air is no longer provided to the room. Below, you can read about what causes freon leaks in air conditioner to help you understand the issue better and hopefully can take proper step needed to restore the system faster.

Most Common Reasons Behind Refrigerant Leaks

Freon, which is also commonly referred to as refrigerant, is one of primary components of an air conditioner. It helps during the process of converting liquid into gas that result in heat absorption to lower the temperature of a house. Freon involves a specific chemical compound that constantly evaporates and condenses in the coils system.

Freon possesses a risk for health as it’s considered as a lethal toxic substance, that means it’s poisonous and can cause death. Due to this reason, the leak of this material is dangerous and should be handled by a professional AC repair technician. Moreover, a leak of this substance is unsafe for the environment as it contributes to ozone depletion.

What Causes Freon Leaks in Air Conditioner

Here are some of the most common causes of Freon leaks:

  • Improper installment

Freon leaks can occur because of HVAC unit poor installation, such as the over-tight situation on the flare connection. This is why it’s important to make sure that your air conditioning system is installed only by a professional and licensed technician.

Several warning symptoms of this problem include blown warm air from the system, malfunction of the thermostat, improper airflow inside the building, improper heating, and many more.

  • Metal Erosion

HVAC system can suffer significantly due to erosion. As an example, erosion can create small holes in which the refrigerant leaks through. The AC units placed outside are typically more susceptible of this condition. In addition, some substance such as formic acid can also affect the copper tubes and lines by making them corrode faster.

  • Factory Error

As it applies to any mass-produced product, there’s also a chance that an AC unit has factory defects. One of the possible errors from factory is defect of the refrigerant lines that causes Freon leak. This might be indicated by some signs such as efficiency issues or high energy bills. You will need a replacement if you happened to receive a brand-new unit with factory error. Most manufacturers offer warranty that can help in replacing or fixing the defected air conditioner.

  • Wear and Tear

Another potential cause of refrigerant leaks is worn and tear that tends to happen more on older AC units. Aging systems may lead to worn out rubber seals found on the valve stems. Rust can also occur over time. Either way, they can result in Freon leaks.

Now, you may wonder: does freon leak when AC is off? The answer is yes. Even when the AC is not operating, the refrigerant leak can still take place and cause further issue.

It is important to note that refrigerant leak is not something that should be handled on your own. Immediately contact a local professional air conditioner repairman or company to check the system if you notice any sign of refrigerant leaks. In the meantime, the guide on what causes freon leaks in air conditioner above may be helpful for you to recognize the signs better.
