Where Is The Most Common AC Leak?

It is essential to conduct a visual inspection every one to two months to ensure the AC system is in the right working condition.

1. Signs That Indicate There Is Refrigerant Leakage In The System

You need to call a professional AC repair technician if you notice any of the following signs of refrigerant leakage:

  • AC units time to lower the room temperature
  • A surge in the electricity bills
  • Increased humidity levels
  • Hissing sound from or around the AC system
  • Water dripping from the indoor air unit

2. Most Common Places To Look For AC Refrigerant Leakage

Here are the places where you should look for leakage if your AC system shows refrigerant leakage signs. Contact Mini Split AC in Lawndale CA if you find any leakage:

  • Capillary tube: The capillary tube is a thin, long, fixed-length copper tube found in the outdoor unit near the condenser coils. The role of the capillary tube is to maintain the refrigerant pressure as it moves toward the evaporator coil in the indoor unit.

    The capillary tube’s mounting hardware often gets damaged as it loosens due to constant vibrations from the condenser’s motor. As the loosened parts start to rub against other metal components, the tube develops tiny holes due to friction.

  • Flare fittings: You can find flare fittings in the air conditioning system when a capillary tube or any metal section of components needs to be connected to different AC metallic components. A flare fitting requires a flare nut that is tightened and compressed at the end of the metallic tube to prevent refrigerant leakage.

    However, with time and constant vibrations from the condenser motor, the flare fitting nuts loosen, leaving the refrigerant to escape.

  • Evaporator coil: Evaporator coils are one of the fundamental components in the AC system assembly as it helps cool down the air. It contains the compressed refrigerant that takes the heat from the indoor air and cools down the surrounding air.

    However, in the heat transfer process, the air cools down rapidly and forms condensation droplets on the coils. These droplets react with VOCs (Volatile organic compounds) in your room, forming formic acid. Formic acid precipitate eats away the copper coils, and the coils form tiny holes from where refrigerant can leak away.

3. Causes Behind A Refrigerant Leakage

Here are some reasons that can cause a refrigerant leakage. Contact the Mini Split AC experts in Lawndale CA if you any leakage occurs:

  • Corrosion
  • Weakened or extremely tightened joints in the system
  • Improper insulation
  • Factory defects
  • Wear and tear

Final Thoughts

Contact the Mini Split AC Installation experts of Lawndale CA, if you find refrigerant leakage in the AC system. It is essential to detect the refrigerant leakage issue as early as possible. Otherwise, it can impact the functioning of the entire AC system and lead to compressor failure.
