When your air conditioner isn’t cooling as efficiently as it used to, or you hear a faint hissing sound coming from the unit, it could be more than just wear and tear—it might be a gas leak. Gas leaks in air-conditioning systems are among the most common and often overlooked issues that can impact your home’s comfort and safety. In Sydney’s hot summers, timely gas leak repair is essential to keep your air conditioning running efficiently and prevent further damage.
In this guide, we’ll help you understand the common causes of refrigerant leaks, how to identify air conditioner gas leak symptoms, and when to contact a professional for AC refrigerant leak detection and repair.
What Causes Air Conditioner Gas Leaks?
Understanding the air-conditioning system gas leak causes can help you catch the problem before it worsens. Refrigerant gas—often referred to as Freon or R32—is what enables your air conditioner to cool indoor air. When this gas leaks, your system loses its cooling efficiency and can suffer long-term damage.
Here are the common causes of refrigerant leaks in AC units:
Corroded Copper Coils
Over time, the copper coils that carry refrigerant can corrode due to chemical reactions between moisture and volatile organic compounds (VOCs). This is a leading cause of air conditioner refrigerant gas leaks in Sydney homes.
Loose Connections or Poor Installation
Improper installation or weak joints in your split system air conditioner can lead to small leaks. If you’ve recently had your system installed, ensure it was fitted by a licensed professional to prevent early issues.
Vibration Damage
Continuous vibration of the AC unit can loosen connections over time, creating tiny gaps where refrigerant can escape. These leaks may start small but worsen if left unaddressed.
Aging Components
Older units are more prone to wear and tear. Components like seals and valves may degrade, leading to AC system under-charging due to gas leaks.
If you suspect your unit is leaking, don’t delay professional gas leak detection for air conditioning units—it can save you from higher costs later.
Warning Signs of an AC Refrigerant Leak
Knowing the air conditioner gas leak symptoms early can prevent system breakdowns. Here are the most common warning signs of AC refrigerant leak issues:
Hissing or Bubbling Sounds
A tell-tale air conditioner hissing sound gas leak often points to a refrigerant escaping through a small hole or crack. Bubbling noises may indicate a more significant leak.Reduced Cooling Efficiency
If your AC is blowing warm air or taking longer to cool a room, it might be due to a gas leak in split system air conditioner.Ice on Coils or Lines
A lack of refrigerant can cause the evaporator coil to freeze, leading to ice build-up inside the unit.Higher Energy Bills
A leaking unit works harder to maintain temperature, leading to increased energy use and higher bills.Unpleasant Odours
A faint chemical smell may be a sign of refrigerant leakage and should be addressed immediately.
If you’ve noticed one or more of these signs, your system likely needs professional AC refrigerant leak repair Sydney or ducted air conditioner gas leak repair Sydney services.
