At AirPoint, we understand the importance of maintaining your air conditioning system. However, we also understand that it can be challenging to detect when your AC system has a refrigerant leak. Refrigerant leaks can cause significant damage to your system and can be a safety hazard if left unchecked.

In this article, we will provide you with detailed information on AC refrigerant leaks and how to prevent them.

What Causes AC Refrigerant Leaks?

AC refrigerant leaks can be caused by various factors, such as wear and tear, corrosion, and faulty installation. When refrigerant leaks, it can cause your AC system to malfunction, leading to warm air blowing out of your vents, increased humidity, and higher energy bills. Additionally, refrigerant leaks can damage your compressor and other components in your AC system, resulting in costly repairs or replacement.

Signs of AC Refrigerant Leaks

Before we dive into the detection and fixing process, let’s first identify common signs of an AC refrigerant leak. The following are the signs you may notice if your AC has a refrigerant leak:

  1. Reduced Cooling: If your AC is not cooling your home as it used to, it could be a sign of a refrigerant leak. Low refrigerant levels can cause the AC to work harder, reducing its cooling capacity.
  2. Hissing or Bubbling Sounds: If you hear hissing or bubbling sounds coming from your AC unit, it could indicate a refrigerant leak. The sound comes from the refrigerant escaping through the leak.
  3. Warm Airflow: If your AC is blowing warm air instead of cold, it could be due to a refrigerant leak. Low refrigerant levels can cause the AC to produce warm air.
  4. Ice Buildup: If there is ice buildup on your AC unit, it could be due to a refrigerant leak. Low refrigerant levels can cause the evaporator coil to freeze, leading to ice buildup.

Locating the Leak:

Once you have identified the signs of a refrigerant leak, the next step is to locate the leak. Locating the leak can be challenging, and it’s best to leave it to professionals. However, if you want to attempt to find the leak yourself, follow these steps:

  1. Turn off the AC: Before you start, turn off the AC unit to avoid any accidents or injuries.
  2. Check the Condenser Coil: The condenser coil is located outside and is responsible for removing heat from the refrigerant. Check for any signs of damage, such as corrosion or physical damage.
  3. Check the Refrigerant Lines: The refrigerant lines are responsible for transporting refrigerant to and from the AC unit. Inspect the lines for any cracks, holes, or signs of wear and tear.
  4. Check the Evaporator Coil: The evaporator coil is located inside the AC unit and is responsible for absorbing heat from your home. Check for any signs of damage or ice buildup.

Preventing AC Refrigerant Leaks

Preventing AC refrigerant leaks is vital to keeping your system running efficiently and prolonging its lifespan. One way to prevent refrigerant leaks is to schedule regular maintenance with a professional AC technician. During maintenance, the technician will check for refrigerant leaks and other issues that can cause problems. Additionally, make sure to change your air filters regularly to prevent clogging, which can cause your system to work harder and potentially cause a refrigerant leak.

What to Do If You Suspect an AC Refrigerant Leak

If you suspect an AC refrigerant leak, it’s essential to take action right away. The longer you wait, the more damage can occur, leading to costly repairs or replacement. The first step is to turn off your AC system to prevent further damage. Next, contact a professional AC technician to inspect your system for leaks and determine the best course of action.
