Air conditioners are essential for maintaining a comfortable indoor environment, particularly during hot summer days. However, like any other home appliance, they can face issues, one of which is refrigerant leaks. ALP Heating, a leading HVAC service provider understands the complexities of refrigerant leaks and is here to help. Here, we will delve into the causes, signs, and solutions for refrigerant leaks in air conditioning units.

Causes of Refrigerant Leaks in Air Conditioners

There are numerous causes for refrigerant leaks in Air conditioners.
The most common causes include:

  1. Corrosion: Corrosion of the refrigerant lines, particularly the copper tubing, can result from long-term exposure to moisture or chemicals in the air. This corrosion weakens the copper coils, creating tiny holes and cracks that cause refrigerant leaks.
  2. Manufacturing defects: Poor manufacturing or faulty installation may lead to weak connections in the refrigerant lines or inadequate welding, causing the refrigerant to leak out.
  3. Vibration and wear: Over time, the constant vibrations from an air conditioner’s operation can cause wear and tear on the refrigerant lines, resulting in leaks.
  4. Accidental damage: Mishandling during installation, maintenance, or moving the air conditioner can cause physical damage to the refrigerant lines, leading to leaks.

Signs of a Refrigerant Leak in Your Air Conditioner

  1. Reduced cooling efficiency: A refrigerant leak may cause your air conditioner to lose its cooling power, making it less effective in maintaining the desired temperature.
  2. Frozen condensation on the evaporator coil: When there’s insufficient refrigerant, the evaporator coil may become too cold, causing condensation to freeze and form ice on the coil.
  3. Hissing or bubbling noises: These sounds in the air conditioner may indicate a refrigerant leak, as gas escapes from the damaged area.
  4. High energy bills: With a refrigerant leak, your air conditioner will work harder and consume more energy to achieve the desired temperature, leading to increased energy bills.
  5. Not blowing cool air: You can quickly check by putting your palm directly in front of your vents. If you’ve tried everything to remedy the problem but the air coming from the vents seems warm, your AC may have a Freon leak.
